I've read in a few trip reviews about people winning hundreds of dollars on the penny slots. When most people **max bet on penny slots** about winning big on pennies they max bet on penny slots go on a roll and have betting games large wins coupled with some small to mid sized wins. I go with a set amount of money to have fun, and if I win that makes it even more fun I would love to see these mystical slots where max bet is only five coins because it's been ages since I've seen those - max bet seems to be more 10 to 20 coins per line lately. A good payoff for a single coin per line bettor on a penny slot is a hundred dollars or so.

Our idealized limit model is based on a continuum of assets indexed by a hyperfinite Loeb measure space, and it is asymptotically implementable in a setting with a large but finite number of assets. Because the difficulties in the formulation of the law of large numbers with a standard continuum of random variables are well known, the model uncovers some basic phenomena not amenable to classical methods, and whose approximate counterparts are not already, or even readily, apparent in the asymptotic setting.

The capital-asset- pricing model and arbitrage pricing theory : a unification. This distinction yields a valuation formula involving only the essential risk embodied in an asset's return, where the overall risk can be decomposed into a systematic and an unsystematic part, as in the arbitrage pricing theory ; and the systematic component further decomposed into an essential and an inessential part, as in the capital-asset- pricing model.

A new look at some basic concepts in arbitrage pricing theory. In this paper we establish a version of the Kramkov's optional decomposition theorem in the setting of equivalent martingale measures. Based on this theorem, we have a new look at some basic concepts in arbitrage pricing theory : superhedging, fair price ,attainable contingent claims, complete markets and etc.

Stochastic arbitrage return and its implications for option pricing. The purpose of this work is to explore the role that arbitrage opportunities play in pricing financial derivatives. We use a non-equilibrium model to set up a stochastic portfolio, and for the random arbitrage return, we choose a stationary ergodic random process rapidly varying in time.

We exploit the fact that option price and random arbitrage returns change on different time scales which allows us to develop an asymptotic pricing theory involving the central limit theorem for random proces Stochastic arbitrage return and its implication for option pricing. The purpose of this work is to explore the role that random arbitrage opportunities play in pricing financial derivatives. We exploit the fact that option price and random arbitrage returns change on different time scales which allows us to develop an asymptotic pricing theory involving the central limit theorem for random processes.

We restrict ourselves to finding pricing bands for options rather than exact prices. The resulting pricing bands are shown to be independent of the detailed statistical characteristics of the arbitrage return. Dynamic option pricing with endogenous stochastic arbitrage. Only few efforts have been made in order to relax one of the key assumptions of the Black-Scholes model: the no- arbitrage assumption.

This is despite the fact that arbitrage processes usually exist in the real world, even though they tend to be short-lived. The purpose of this paper is to develop an option pricing model with endogenous stochastic arbitrage , capable of modelling in a general fashion any future and underlying asset that deviate itself from its market equilibrium. The theoretical results obtained for Binary and European call options, for this kind of arbitrage , show that an investment strategy that takes advantage of the identified arbitrage possibility can be defined, whenever it is possible to anticipate in relative terms the amplitude and timespan of the process.

Finally, the new trajectory of the stock price is analytically estimated for a specific case of arbitrage and some numerical illustrations are developed. We find that the consequences of a finite and small endogenous arbitrage not only change the trajectory of the asset price during the period when it started, but also after the arbitrage bubble has already gone. In this context, our model will allow us to calibrate the B-S model to that new trajectory even when the arbitrage already started.

In APT, the returns of securities are affected by several factors. This research is aimed to estimate the expected returns of securities using APT model and Vector Autoregressive model. There are ten stocks incorporated in Kompas index and four macroeconomic variables, these are inflation, exchange rates, the amountof circulate money JUB, and theinterest rateof Bank Indonesia SBI are applied in this research.

The first step in using VAR is to test the stationary of the data using colerogram and the results indicate that all data are stationary. The second step is to select the optimal lag based on the smallest value of AIC. The Granger causality test shows that the LPKR stock is affected by the inflation and the exchange rate while the nine other stocks do not show the existence of the expected causality. The results of causality test are then estimated by the VAR models in order to obtain expected returnof macroeconomic factors.

Fractal asset returns, arbitrage and option pricing. In the discrete-time fractional random walk model a market with one risky asset affords an arbitrage opportunity as described by Cutland et al. Stock price returns and the Joseph effect: a fractional version of the Black-Scholes model.

Finance Stoch ;5 3 ]. We briefly discuss these results and compute a numerical example in a fractional binomial model as illustration and mention an option pricing model for assets the returns of which are driven by a fractional Brownian motion [Yaozhong Hu, Bernt Oksendal. Fractional white noise calculus and applications to finance. Volatility estimation and option pricing with fractional Brownian motion, October Electricity- price arbitrage with plug-in hybrid electric vehicle: Gain or loss?

Customers, utilities, and society can gain many benefits from distributed energy resources DERs , including plug-in hybrid electric vehicles PHEVs. There is, however, disagreement on the magnitude of such profit. The simulation results indicate that under current market structure, even with significant improvement in battery technologies e. This finding implies that expected arbitrage profit solely is not a viable option to engage PHEVs larger adoption.

Volatility smile and stochastic arbitrage returns. We exploit the fact that option price and random arbitrage returns change on different time scales which allows us to develop an asymptotic pricing theory involving the central limit theorem for random Arbitrage Opportunities and their Implications to Derivative Hedging. We explore the role that random arbitrage opportunities play in hedging financial derivatives. We extend the asymptotic pricing theory presented by Fedotov and Panayides [Stochastic arbitrage return and its implication for option pricing , Physica A , ] for the case of hedging a derivative when arbitrage opportunities are present in the market.

We restrict ourselves to finding hedging confidence intervals that can be adapted to the amount of arbitrage risk an investor will per A remark on the set of arbitrage -free prices in a multi-period model. Furthermore, we provide Arbitrage free pricing of forward and futures in the energy market.

This thesis will describe a method for an arbitrage -free evaluation of forward and futures contracts in the Nordic electricity market. This is a market where it is not possible to hedge using the underlying asset which one normally would do. The electricity market is a relatively new market, and is less developed than the financial markets. The pricing of energy and energy derivatives are depending on factors like production, transport, storage etc. There are different approaches when pricing a forward contract in an energy market.

With motivation from interest rate theory , one could model the forward prices directly in the risk neutral world. Another approach is to start out with a model for the spot prices in the physical world, and then derive theoretical forward prices , which then are fitted to observed forward prices.

These and other approaches are described by Clewlow and Strickland in their book, Energy derivatives. This thesis uses the approach where I start out with a model for the spot price , and then derive theoretical forward prices. I use a generalization of the multifactor Schwartz model with seasonal trends and Ornstein Uhlenbeck processes to model the spot prices for electricity.

This continuous-time model also incorporates mean-reversion, which is an important aspect of energy prices. Historical data for the spot prices is used to estimate my variables in the multi-factor Schwartz model. Then one can specify arbitrage -free prices for forward and futures based on the Schwartz model.

The result from this procedure is a joint spot and forward price model in both the risk neutral and physical market, together with knowledge of the equivalent martingale measure chosen by the market. This measure can be interpreted as the market price of risk, which is of interest for risk management. In this setup both futures and forward contracts will have the same pricing dynamics, as the only difference between the two types of contracts is how the payment for the.

Arbitrage strategy. An arbitrage strategy allows a financial agent to make certain profit out of nothing, i. This has to be disallowed on economic basis if the market is in equilibrium state, as opportunities for riskless profit would result in an instantaneous movement of prices of certain financial instruments.

The principle of not allowing for arbitrage opportunities in financial markets has far-reaching consequences, most notably the option- pricing and hedging formulas in c Arbitrage opportunities and their implications to derivative hedging. We extend the asymptotic pricing theory presented by Fedotov and Panayides [Stochastic arbitrage return and its implication for option pricing , Physica A ] for the case of hedging a derivative when arbitrage opportunities are present in the market.

We restrict ourselves to finding hedging confidence intervals that can be adapted to the amount of arbitrage risk an investor will permit to be exposed to. The resulting hedging bands are independent of the detailed statistical characteristics of the arbitrage opportunities. Price formation and intertemporal arbitrage within a low-liquidity framework. Empirical evidence from European natural gas markets. In this study, the informational efficiency of the European natural gas market is analyzed by empirically investigating price formation and arbitrage efficiency between spot and futures markets.

Econometric approaches are specified that explicitly account for nonlinearities and the low liquidity framework of the considered gas hubs. The empirical results reveal that price discovery takes place on the futures market, while the spot price subsequently follows the futures market price. Furthermore, there is empirical evidence of significant market frictions hampering intertemporal arbitrage. UK's NBP seems to be the hub at which arbitrage opportunities are exhausted most efficiently, although there is convergence in the degree of intertemporal arbitrage efficiency over time at the hubs investigated.

Full Text Available This paper derives, from a pedagogic perspective, the Arbitrage Pricing Model, which is an important asset pricing model in modern finance. The derivation is based on the idea that, if a self-financed investment has no risk exposures, the payoff from the investment can only be zero. Microsoft Excel plays an important pedagogic role in this paper. The Excel illustration not only helps students recognize more fully the various nuances in the model derivation, but also serves as a good starting point for students to explore on their own the relevance of the noise issue in the model derivation.

Practical operation strategies for pumped hydroelectric energy storage PHES utilising electricity price arbitrage. In this paper, three practical operation strategies 24Optimal, 24Prognostic, and 24Hsitrocial are compared to the optimum profit feasible for a PHES facility with a MW pump, MW turbine, and a 2 GWh storage utilising price arbitrage on 13 electricity spot markets. The results indicate However, to maximise profits with the 24Optimal strategy, the day Otherwise, the predicted profit could be significantly reduced and even become a loss.

However, to maximise profits with the 24Optimal strategy, the day-ahead electricity prices must be the actual prices which the PHES facility is charged or the PHES operator must have very accurate price predictions. Finally, using the 24Optimal strategy, the PHES profit can surpass the annual investment repayments required.

Considering the year lifetime of PHES, even with low investment costs, a low interest rate, and a suitable electricity market, PHES is a risky investment without a more predictable profit. A hybrid credibility-based fuzzy multiple objective optimisation to differential pricing and inventory policies with arbitrage consideration.

In most markets, price differentiation mechanisms enable manufacturers to offer different prices for their products or services in different customer segments; however, the perfect price discrimination is usually impossible for manufacturers. The importance of accounting for uncertainty in such environments spurs an interest to develop appropriate decision-making tools to deal with uncertain and ill-defined parameters in joint pricing and lot-sizing problems. This paper proposes a hybrid bi-objective credibility-based fuzzy optimisation model including both quantitative and qualitative objectives to cope with these issues.

Taking marketing and lot-sizing decisions into account simultaneously, the model aims to maximise the total profit of manufacturer and to improve service aspects of retailing simultaneously to set different prices with arbitrage consideration. After applying appropriate strategies to defuzzify the original model, the resulting non-linear multi-objective crisp model is then solved by a fuzzy goal programming method.

An efficient stochastic search procedure using particle swarm optimisation is also proposed to solve the non-linear crisp model. Full Text Available Price arbitrage involves taking advantage of an electricity price difference, storing electricity during low- prices times, and selling it back to the grid during high- prices periods.

This strategy can be exploited by customers in presence of dynamic pricing schemes, such as hourly electricity prices , where the customer electricity cost may vary at any hour of day, and power consumption can be managed in a more flexible and economical manner, taking advantage of the price differential.

Instead of modifying their energy consumption, customers can install storage systems to reduce their electricity bill, shifting the energy consumption from on-peak to off-peak hours. This paper develops a detailed storage model linking together technical, economic and electricity market parameters.

The model can be applied to several kinds of storages, although the simulations refer to three kinds of batteries: lead-acid, lithium-ion Li-ion and sodium-sulfur NaS batteries. This could be particularly useful when the customer load profile cannot be scheduled with sufficient reliability, because of the uncertainty inherent in load forecasting. The motivation behind this research is that storage devices can help to lower the average electricity prices , increasing flexibility and fostering the integration of renewable sources into the power system.

This is a teaching note on a proposed approach that will correct a common flaw in the way the return-generating process within the APT framework is illustrated in textbooks. The problem can be resolved by dichotomizing the risk factors into two kinds.

Based on this approach, the author eliminated the main source of confusion and developed an…. Bonnans, J. Frederic, E-mail: frederic. We suggest a numerical approximation for an optimization problem, motivated by its applications in finance to find the model-free no- arbitrage bound of variance options given the marginal distributions of the underlying asset.

A first approximation restricts the computation to a bounded domain. Then we propose a gradient projection algorithm together with the finite difference scheme to solve the optimization problem. We prove the general convergence, and derive some convergence rate estimates. Finally, we give some numerical examples to test the efficiency of the algorithm. The role of transactions costs are explored vis-a-vis the law of one price.

Weekly data, February 3rd, through October 9th, , are used in the analysis. Results indicate that nonlinearity and structural change are important features of these markets; price Advertising Arbitrage. Speculators often advertise arbitrage opportunities in order to persuade other investors and thus accelerate the correction of mispricing. We show that in order to minimize the risk and the cost of arbitrage an investor who identifies several mispriced assets optimally advertises only one of them, and overweights it in his portfolio; a risk-neutral arbitrageur invests only in this asset.

The choice of the asset to be advertised depends not only on mispricing but also on its "advertisability" North American oriented strand board markets, arbitrage activity, and market price dynamics: A smooth transition approach. Price dynamics for North American oriented strand board markets are examined. Nonlinearities induced by unobservable transactions costs are modeled by estimating time-varying smooth transition autoregressions TV-STARs.

Results indicate that nonlinearity and structural change are important Epistemic Arbitrage. The article outlines how transnational professionals can be understood as unique groups that have careers and operate in networks where there is a supply of, and demand for, epistemic Hedging, arbitrage and optimality with superlinear frictions.

Such frictions induce a duality between feasible trading strategies and shadow execution prices with a martingale measure. Utility maximizing strategies exist even if arbitrage is present, because it is n No- arbitrage bound is established with no- arbitrage theory considering all kinds of trade costs, different deposit and loan interest rate, margin and tax in fuuaes markets.

The empirical results find that there are many lower bound arbitrage opportunities in China copper futures market from August 8th, to August 16th, Concretely, no- arbitrage opportunity is dominant and lower bound arbitrage is narrow in normal market segment. Lower bound arbitrage almost always exists with huge magnitude in inverted market segment. There is basically no- arbitrage in normal market because spot volume is enough, so that upper or lower bound arbitrage can be realized.

There is mostly lower bound arbitrage in inverted market because spot volume is lack. Non-equilibrium price theories. We propose two theories for the formation of stock prices under the condition that the number of available stocks is fixed. Both theories consider the balance equations for cash and several kinds of stocks. They also take into account interest rates, dividends, and transaction costs.

The proposed theories have the advantage that they do not require iterative procedures to determine the price , which would be inefficient for simulations with many agents. Asset Pricing - A Brief Review. I first introduce the early-stage and modern classical asset pricing and portfolio theories. Finally, I discuss the most recent development during the last decade and the outlook in the field of asset pricing.

Full Text Available Investing in the stock market is one option for investors. Investment in ordinary shares was classified as longterminvestments to be able to provide added value and the risk for fixed income. Thisstudy was based on the assumption that: there were differences in sectoral stock return volatility, volatility ofmarket risk factors, and macroeconomic risks affecting sectoral differences in the sensitivity of stock returns;there were differences in the results of testing the validity, robustness unconditional CAPM and APTMmultifactorial; and time-varying volatility referring to the phenomena of structural breaks and asymmetriceffect.

The method of analysis used nested models with panel data. Data were analyzed by using secondary datafrom The results of this study concluded that: there was no different sensitivity of stock returnsacross sectors, but there was different insensitivity between systematic risk factors, CAPM and APTM multifactorthat showed the inconsistency of the sectoral shares, but the proven model of unconditional CAPM wasvalid; the difference of factor risk premiums was as a result of the structural break, the financial crisis period of within the period These models are particularly useful for long horizon asset-liability management as they allow the modelling of long term stock returns with heavy tail ergodic diffusions, with tractable, time homogeneous dynamics, and which moreover admit a complete financial market, leading to unique pricing and hedging strategies.

Unfortunately the standard specifications of these models in literature admit arbitrage opportunities. We investigate in detail the features of the existing model specifications which create these arbitrage opportunities and consequently construct a modification that is arbitrage free. Project valuation and investment decisions: CAPM versus arbitrage.

As a consequence, the standard use of CAPM for project valuation and decision making should be reconsidered. This thesis proposes a theory of inefficient markets that uses limited rational choice as a central trait and I call it the theory of Homo comperiens.

The theory limits the alternatives and states that the subjects are aware of and only allow them to have rational preference relations on the limited action set and state set, i. With limited rational choice, I drive a wedge between the market price and the intrinsic value and thus create an arbitrage market Statistical field theory of futures commodity prices.

The statistical theory of commodity prices has been formulated by Baaquie Further empirical studies of single Baaquie et al. In this paper, the model for spot prices Baaquie, is extended to model futures commodity prices using a statistical field theory of futures commodity prices. The futures prices are modeled as a two dimensional statistical field and a nonlinear Lagrangian is postulated. Empirical studies provide clear evidence in support of the model, with many nontrivial features of the model finding unexpected support from market data.

According to arbitrage -free principle, we first discretize the continuous-time model. Then, in each small time interval, the transaction costs are introduced. Hedonic price theory : Concept and applications. Direct and indirect techniques are being used to estimate economic consequences of proximity to existing or proposed public facilities.

The hedonic price theory , an indirect technique, is the most logically suited, especially for capturing the shadow or implicit price of a characteristic such as proximity in the real estate market. While the theory is increasingly being used, there is also a growing tendency to draw inferences from the study of one or more hazards and situations and transfer the conclusions to a very different hazard and situation.

The use of the hedonic price theory and the issue of transferability to radioactive waste facilities are addressed in this paper. The Convertible Arbitrage Strategy Analyzed. This paper analyzes convertible bond arbitrage on the Canadian market for the period to Convertible bond arbitrage is the combination of a long position in convertible bonds and a short position in the underlying stocks.

Full Text Available For decades, there were many models explaining the returns earned emerged in order to fulfil the curiosity had by human. Therefore, many comparative studies between models were accomplished. Besides, the author also attempts to find how much inflation, interest rate, and exchange rate describe the returns earned in each sector existed in Indonesia Capital Market.

Besides, the author also found that among macroeconomic factors, there are only two macroeconomic factors that can affect certain samples significantly. Regret Theory and Equilibrium Asset Prices. Full Text Available Regret theory is a behavioral approach to decision making under uncertainty. In this paper we assume that there are two representative investors in a frictionless market, a representative active investor who selects his optimal portfolio based on regret theory and a representative passive investor who invests only in the benchmark portfolio.

In a partial equilibrium setting, the objective of the representative active investor is modeled as minimization of the regret about final wealth relative to the benchmark portfolio. In equilibrium this optimal strategy gives rise to a behavioral asset priciting model. We also extend our model to a market with multibenchmark portfolios. Empirical tests using stock price data from Shanghai Stock Exchange show strong support to the asset pricing model based on regret theory.

Triangular arbitrage in the foreign exchange market. We first review our previous work, showing what is the triangular arbitrage transaction and how to quantify the triangular arbitrage opportunity. Next we explain that the correlation of the foreign exchange rates can appear without actual triangular arbitrage transaction.

Defining electricity markets. An arbitrage cost approach. Market definition is a crucial component of antitrust policy. There is, however, no universally accepted method of carrying out market definition. While several approaches have been presented in the literature, each has its share of drawbacks. This paper suggests that a modeling technique based upon the theory of arbitrage is well suited to answering this question.

After the empirical approach is presented, it is used to calculate antitrust market definitions between electricity hubs in the American West. No- arbitrage bounds for financial scenarios. We derive no- arbitrage bounds for expected excess returns to generate scenarios used in financial applications.

The bounds allow to distinguish three regions: one where arbitrage opportunities will never exist, a second where arbitrage may be present, and a third, where arbitrage opportunities An arbitrage is a serious inefficiency of a financial market, and it is traditionally considered to completely disrupt a price system and to allow agents for growing unlimitedly rich. By means of a simple example, this paper points out that this is only true when dealing with positively homogeneous price systems; indeed, in more general financial market models taking into consideration, e.

Industrial Pricing : Theory and Managerial Practice. We organize the existing theoretical pricing research into a new two-level framework for industrial goods pricing. The second level consists of the pricing strategies appropriate for a given situation. For example, within the new product pricing situation, there are three alternative pricing strategies: Skim, Penetration, and Experience Curve pricing.

There are a total of ten pricing s The true invariant of an arbitrage free portfolio. It is shown that the arbitrage free portfolio paradigm being applied to a portfolio with an arbitrary number of shares N allows for the extended solution in which the option price F depends on N. Therefore the stock hedging expense is the true invariant of the arbitrage free portfolio paradigm. Arbitrage -free valuation of energy derivatives. This chapter focuses on techniques available for valuing energy-contingent claims and develops an arbitrage -free framework to value energy derivatives.

The relationship between the spot, forward and futures prices is explained. Option valuation with deterministic convenience yields is discussed using an extension of the Black framework, and details of the risk-neutral valuation of European options, and valuation of American and European-style options are given.

Option valuations with stochastic convenience yields, the evolution of the term structure of convenience yield, and a tree approach to valuing American and other options are discussed. Applications and limitations of the models for pricing energy derivative products are considered.

The stochastic differential equation for the futures prices when the convenience yields are stochastic is presented in an appendix. Motivated by the literature on limits-to- arbitrage , we build an equilibrium model of commodity markets in which speculators are capital constrained, and commodity producers have hedging demands for commodity futures. Increases decreases in producers' hedging demand speculators' risk-capacity increase hedging costs via price -pressure on futures, reduce producers' inventory holdings, and thus spot prices.

Consistent with our model, producers' default risk forecasts futures returns, spot pri Arbitrage , market definition and monitoring a time series approach. This article considers the application to regional price data of time series methods to test stationarity, multivariate cointegration and exogeneity. The discovery of stationary price differentials in a bivariate setting implies that the series are rendered stationary by capturing a common trend and we observe through this mechanism long-run arbitrage.

This is indicative of a broader market definition and efficiency. The problem is considered in relation to more than weekly data points on A multidimensional subdiffusion model: An arbitrage -free market. In this article, we introduce a multidimensional subdiffusion model that has a bond and K correlated stocks. This model describes the period of stagnation for each stock and the behavior of the dependency between multiple stocks.

Moreover, we derive the multidimensional fractional backward Kolmogorov equation for the subordinated process using the Laplace transform technique. Finally, using a martingale approach, we prove that the multidimensional subdiffusion model is arbitrage -free, and also gives an arbitrage -free pricing rule for contingent claims associated with the martingale measure. Discussion of discriminatory pricing by journal publishers and its effects on libraries focuses on six prerequisites for successful discriminatory pricing that are based on marketing theory.

Strategies to eliminate some of these prerequisites--and therefore eliminate discriminatory pricing --are suggested, including the need to change the attitudes…. Estimating the value of electricity storage in PJM. Arbitrage and some welfare effects. Significant increases in prices and price volatility of natural gas and electricity have raised interest in the potential economic opportunities for electricity storage. In this paper, we analyze the arbitrage value of a price -taking storage device in PJM power transmission organization in the USA during the six-year period from to , to understand the impact of fuel prices , transmission constraints, efficiency, storage capacity, and fuel mix.

The impact of load-shifting for larger amounts of storage, where reductions in arbitrage are offset by shifts in consumer and producer surplus as well as increases in social welfare from a variety of sources, is also considered. An investigation on the relationship between arbitrage and macro-economic indicators: A case study of Tehran Stock Exchange.

Full Text Available This paper presents an empirical investigation to study the effects of macro-economic factors on the performance of stocks listed on Tehran Stock Exchange TSE. The proposed study considers the effects of money supply, inflation rate, oil price , unforeseen changes in the course structure of interest rates as well as unanticipated changes in industrial production on stock price.

Using seasonal information of stock price over the period as well as regression analysis, the study has determined that risk premium of unforeseen changes in the course structure of interest rates, money supply, inflation rate and unanticipated changes in industrial production are meaningful when the level of significance is five percent.

In other words, Arbitrage pricing theory model describing the expected return per share is reasonable and macro-level variables explain systematic risk on TSE. A simple counterexample shows the the widely used WACC approach to value leverage firms developed by Miles and Ezzell can create an arbitrage opportunity. The only consequence to be drawn is that their WACC approach cannot be applied under the circumstances assumed by Miles and Ezzell. We show how the WACC has to be modified in order to obtain proper results.

We develop a theory in continuous as well as discrete time. In discrete time it turns out that with a further assumption on the cash fl Dynamic returns of beta arbitrage. This thesis studies the patterns of the abnormal returns of the beta strategy.

The topic can be helpful for professional investors, who intend to achieve a better performance in their portfolios. It is argued that beta arbitrage activity can have impact on the returns of the beta strategy. In fact, it is demonstrated that Does the European natural gas market pass the competitive benchmark of the theory of storage?

Indirect tests for three major trading points. This paper presents the first comparative analysis of the relationship between natural gas storage utilization and price patterns at three major European trading points. Using two indirect tests developed by that are applied in other commodity markets, we impose the no arbitrage condition to model the efficiency of the natural gas market.

The results reveal that while operators of European storage facilities realize seasonal arbitrage profits, substantial arbitrage potentials remain. We suggest that the indirect approach is well suited to provide market insights for periods with limited data.

We find that overall market performance differs substantially from the competitive benchmark of the theory of storage. A utility theory approach for insurance pricing. In this paper, we provide a utility modeling approach to handle insurance pricing and evaluate the tradeoff between discount benefit and deductible level.

A numerical example is also used to illustrate some interesting results. Predicting Malaysian palm oil price using Extreme Value Theory. This paper uses the extreme value theory EVT to predict extreme price events of Malaysian palm oil in the future, based on monthly futures price data for a 25 year period mid to mid Model diagnostic has confirmed non-normal distribution of palm oil price data, thereby justifying the use of EVT.

Both models revealed that the palm oil price will peak at Hedging under arbitrage. It is shown that delta hedging provides the optimal trading strategy in terms of minimal required initial capital to replicate a given terminal payoff in a continuous-time Markovian context.

This holds true in market models where no equivalent local martingale measure exists but only a square-integrable market price of risk. A new probability measure is constructed, which takes the place of an equivalent local martingale measure. In order to ensure the existence of the delta hedge, sufficient SETS, arbitrage activity and stock price dynamics.

This paper provides an empirical description of the relationship between the trading system operated by a stock exchange and the trading behaviour of heterogeneous investors who use the exchange.

Valuating Privacy with Option Pricing Theory. One of the key challenges in the information society is responsible handling of personal data. An often-cited reason why people fail to make rational decisions regarding their own informational privacy is the high uncertainty about future consequences of information disclosures today. This chapter builds an analogy to financial options and draws on principles of option pricing to account for this uncertainty in the valuation of privacy.

For this purpose, the development of a data subject's personal attributes over time and the development of the attribute distribution in the population are modeled as two stochastic processes, which fit into the Binomial Option Pricing Model BOPM. Possible applications of such valuation methods to guide decision support in future privacy-enhancing technologies PETs are sketched. A recent article convincingly nominated the Price equation as the fundamental theorem of evolution and used it as a foundation to derive several other theorems.

A major section of evolutionary theory that was not addressed is that of game theory and gradient dynamics of continuous traits with frequency-dependent fitness. Deriving fundamental results in these fields under the unifying framework of the Price equation illuminates similarities and differences between approaches and allows a simple, unified view of game-theoretical and dynamic concepts.

Using Taylor polynomials and the Price equation, I derive a dynamic measure of evolutionary change, a condition for singular points, the convergence stability criterion, and an alternative interpretation of evolutionary stability. Furthermore, by applying the Price equation to a multivariable Taylor polynomial, the direct fitness approach to kin selection emerges.

Finally, I compare these results to the mean gradient equation of quantitative genetics and the canonical equation of adaptive dynamics. This tradition implies on the one hand, that wealth must be evaluated i. Mainstream economic theory succeeds in price determination with some limits but fails on money integration, while non-mainstream monetary models succeed on money integration but fail on price determination.

Heterodox surplus approach: production, prices , and value theory. In this paper I argue that that there is a heterodox social surplus approach that has its own account of output-employment and prices , and its own value theory which draws upon various heterodox traditions. Starting with the Sraffian technical definition of the social surplus and then working with a Sraffa-Leontief input-output framework, the particular distinguishing feature of the heterodox approach is the role of agency in determining prices , the social surplus, and total social product a From price theory to marketing management.

Historical School, an essential precondition for the Copenhagen approach was the second wave of microeconomic theory of the s. The article argues that it was a marketing management school, and that it offered early contributions to the development of marketing theory.

Purpose — The purpose of this article is to show how a particular marketing paradigm developed in Denmark from the s through the s. It peaked in the mids and faded out with one major publication in the early s. The article provides a relatively detailed study of the initial phases A significant part of the sources are available in Danish only. Findings — While American marketing theory developed from the German Arbitrage hedging strategy and one more explanation of the volatility smile.

We present an explicit hedging strategy, which enables to prove arbitrageness of market incorporating at least two assets depending on the same random factor. The implied Black-Scholes volatility, computed taking into account the form of the graph of the option price , related to our strategy, demonstrates the "skewness" inherent to the observational data. Mispricing and lasting arbitrage between parallel markets in the Czech Republic.

However as this corresponds to a call spread with equal exercise prices , this strategy alone would No- arbitrage , leverage and completeness in a fractional volatility model. When the volatility process is driven by fractional noise one obtains a model which is consistent with the empirical market data. Depending on whether the stochasticity generators of log- price and volatility are independent or are the same, two versions of the model are obtained with different leverage behaviors.

Here, the no- arbitrage and completeness properties of the models are rigorously studied. The no- arbitrage relation between futures and spot prices implies an analogous relation between futures and spot daily ranges. The long-memory features of the range-based volatility estimators are analyzed, and fractional cointegration is tested in a semi-parametric framework. In particular, the no Prospect theory : An application to European option pricing.

Empirical studies on quoted options highlight deviations from the theoretical model of Black and Scholes; this is due to different causes, such as assumptions regarding the price dynamics, markets frictions and investors' attitude toward risk. In this contribution, we focus on this latter issue and study how to value European options within the continuous cumulative prospect theory. According to prospect theory , individuals do not always take their decisions consistently with the maximization An Hilbert space approach for a class of arbitrage free implied volatilities models.

In order to Price competition, level-k theory and communication. The level-k analysis predicts prices to be higher with communication than without. Our experimental evidence lends support to the view that communication affects subjects in a way Moreover, the results indicate that the predictive power of the level-k model does crucially depend on the possibility for high level players to form homogenous beliefs about Fact and fictions in FX arbitrage processes.

The efficient markets hypothesis implies that arbitrage opportunities in markets such as those for foreign exchange FX would be, at most, short-lived. The present paper surveys the fragmented nature of FX markets, revealing that information in these markets is also likely to be fragmented. The "quant" workforce in the hedge fund featured in The Fear Index novel by Robert Harris would have little or no reason for their existence in an EMH world.

The four currency combinatorial analysis of arbitrage sequences contained in [1] is then considered. Their results suggest that arbitrage processes, rather than being self-extinguishing, tend to be periodic in nature. This helps explain the fact that arbitrage dealing tends to be endemic in FX markets. Foreword; Preface; 1. Probability theory : basic notions; 2. Maximum and addition of random variables; 3.

Purchasing power parity theory in a model without international trade of goods. In recent discussions it frequently occurs that the Purchasing Power Parity Theory is identified with Jevons law of one price. By pointing to real world obstacles working against perfect goods arbitrage it is then erroneously concluded that the Purchasing Power Parity Theory cannot be valid while a dinstiction between an absolute version and a relative version of the Purchasing Power Parity Theory is neglected.

In the present paper it is shown that the Purchasing Power Parity Theory in the re Arbitrage and Hedging in a non probabilistic framework. The paper studies the concepts of hedging and arbitrage in a non probabilistic framework. It provides conditions for non probabilistic arbitrage based on the topological structure of the trajectory space and makes connections with the usual notion of arbitrage.

Several examples illustrate the non probabilistic arbitrage as well perfect replication of options under continuous and discontinuous trajectories, the results can then be applied in probabilistic models path by path. The approach is r An empirical test of reference price theories using a semiparametric approach.

In this paper we estimate and empirically test different behavioral theories of consumer reference price formation. Two major theories are proposed to model the reference price reaction: assimilation contrast theory and prospect theory. We assume that different consumer segments will use Realizing the financial benefits of capitation arbitrage. By anticipating the arbitrage potential of cash flow under budgeted capitation, healthcare organizations can make the best use of cash flow as a revenue-generating resource.

Factors that determine the magnitude of the benefits for providers and insurers include settlement interval, withhold amount, which party controls the withhold, and incurred-but-not-reported expenses. In choosing how to structure these factors in their contract negotiations, providers and insurers should carefully assess whether capitation surpluses or deficits can be expected from the provider.

In both instances, the recipient and magnitude of capitation arbitrage benefits are dictated largely by the performance of the provider. Full Text Available Abstract: We consider asset price processes Xt which are weak solutions of one-dimensional stochastic differential equations of the form equation 2 Such price models can be interpreted as non-lognormally-distributed generalizations of the geometric Brownian motion.

This will be applied to some context in statistical information theory as well as to arbitrage theory and contingent claim valuation. For instance, the seminal option pricing theorems of Black-Scholes and Merton appear as a special case. We develop a quality competition model to understand how price controls affect market outcomes in buyer-seller markets with discrete goods of varying quality.

While competitive equilibria do not necessarily exist in such markets when price controls are imposed, we show that stable outcomes do exist and characterize the set of stable outcomes in the presence of price restrictions. In particular, we show that price controls induce non- price competition: price floors induce the trade of ineffici The no- arbitrage efficiency test of the OMX Index option market.

The market efficiency definition is the absence of arbitrage oppor- tunity in the market. We first check the arbitrage opportunity by examining the boundary conditions and the Put-Call-Parity that must be satisfied Then a variance based efficiency test is performed by establish- ing a risk neutral portfolio and re-balance the initial portfolio in different trading strategies.

In order to choose the most appropriate model for option price and hedging strategies, we calibrate several most applied models, i Our results indicate that the AJD model significantly outperforms other models in the option price forecast and the trading strategies.

We introduce a microscopic model which describes the dynamics of each dealer in multiple foreign exchange markets, taking account of the triangular arbitrage transaction. The model reproduces the interaction among the markets well. We explore the relation between the parameters of the present microscopic model and the spring constant of a macroscopic model that we proposed previously.

As usual, we shall use its variance to measure its level of risk. The following is a precise formalization of a basic intuition. By theorem 2 in ref. It is thus natural to refer to all risks perfectly correlated with some linear combinations of the factors, as systematic risks. From another point of view, a principal motivation behind factor analysis is to find a small enough set of latent variables so that the systematic behavior of the directly observed random variables can be adequately identified and explained 20 , If one is allowed to use only m sources of risk to measure the ensemble of systematic risks of the market, then the m random variables ought to be chosen in a way that any other set of m random variables makes a smaller contribution towards explaining the correlational structure of the process of asset returns.

The specification of our underlying framework is now complete, and we turn to the formulation of APT and CAPM, and to a further decomposition of systematic risks. The ensemble of unsystematic risks identified above in the market as a whole satisfy a consistent version of the law of large numbers in the sense that the sample averages of various variations of e are L P -almost surely equal to zero ref.

This fact allows us to compute, from Eq. We can now present the basic theorem of APT, but without the assumption of an exogenously given, exact or approximate, factor structure. It needs to be emphasized that the no arbitrage condition is not only sufficient but also necessary for the validity of the asset pricing formula. Such a necessity condition is surprisingly absent in the APT literature. Theorem 2 does not furnish a precise specification of the portfolio M. We can construct a portfolio I 0 based on parameters extracted from the given market process of asset returns x and use it to identify the essential risk embodied in the realized return of a particular asset.

We can use I 0 to present. We can now present a further refinement of systematic risks, and thereby a tri-partite decomposition of the total risk of an asset. Then, by Eq. The importance of this decomposition lies in the fact that the risk premium of almost all assets is equal to the beta of the asset multiplied by the risk premium of the index portfolio. Once we move to the asymptotic setting of an increasing sequence of finite asset markets, the insights of the limit model can only be extracted in an approximate form.

Space considerations force us to defer a fuller elaboration of the asymptotic interpretation of the model; we only present the asymptotic analogue of Theorem 2 for illustrative purposes. The concrete nature of the idealized limit model that we report above allows us to explore conditions for the existence of various important portfolios—risk-free, factor, mean, cost, and mean-variance efficient—and to develop explicit formulas for them.

The hyperfinite model, besides being asymptotically implementable , also exhibits a universality property in the sense that the distributions of the individual random variables in the ensemble of unsystematic risks may be allowed any variety of distributions It is a pleasure to acknowledge the support of Profs.

It is shown that delta hedging provides the optimal trading strategy in terms of minimal required initial capital to replicate a given terminal payoff in a continuous-time Markovian context. This holds true in market models where no equivalent local martingale measure exists but only a square-integrable market price of risk.

A new probability measure is constructed, which takes the place of an equivalent local martingale measure.

Valuating Privacy with Option Pricing Theory. One of the key challenges in the information society is responsible handling of personal data.

An often-cited reason why people fail to make rational decisions regarding their own informational privacy is the high uncertainty about future consequences of information disclosures today. This chapter builds an analogy to financial options and draws on principles of option pricing to account for this uncertainty in the valuation of privacy. For this purpose, the development of a data subject's personal attributes over time and the development of the attribute distribution in the population are modeled as two stochastic processes, which fit into the Binomial Option Pricing Model BOPM.

Possible applications of such valuation methods to guide decision support in future privacy-enhancing technologies PETs are sketched. A recent article convincingly nominated the Price equation as the fundamental theorem of evolution and used it as a foundation to derive several other theorems. A major section of evolutionary theory that was not addressed is that of game theory and gradient dynamics of continuous traits with frequency-dependent fitness. Deriving fundamental results in these fields under the unifying framework of the Price equation illuminates similarities and differences between approaches and allows a simple, unified view of game-theoretical and dynamic concepts.

Using Taylor polynomials and the Price equation, I derive a dynamic measure of evolutionary change, a condition for singular points, the convergence stability criterion, and an alternative interpretation of evolutionary stability. Furthermore, by applying the Price equation to a multivariable Taylor polynomial, the direct fitness approach to kin selection emerges.

Finally, I compare these results to the mean gradient equation of quantitative genetics and the canonical equation of adaptive dynamics. This tradition implies on the one hand, that wealth must be evaluated i. Mainstream economic theory succeeds in price determination with some limits but fails on money integration, while non-mainstream monetary models succeed on money integration but fail on price determination.

Heterodox surplus approach: production, prices , and value theory. In this paper I argue that that there is a heterodox social surplus approach that has its own account of output-employment and prices , and its own value theory which draws upon various heterodox traditions. Starting with the Sraffian technical definition of the social surplus and then working with a Sraffa-Leontief input-output framework, the particular distinguishing feature of the heterodox approach is the role of agency in determining prices , the social surplus, and total social product a From price theory to marketing management.

The article argues that it was a marketing management school, and that it offered early contributions to the development of marketing theory.

The article provides a relatively detailed study of the initial phases A significant part of the sources are available in Danish only. Findings — While American marketing theory developed from the German Arbitrage hedging strategy and one more explanation of the volatility smile. We present an explicit hedging strategy, which enables to prove arbitrageness of market incorporating at least two assets depending on the same random factor.

When the volatility process is driven by fractional noise one obtains a model which is consistent with the empirical market data. Depending on whether the stochasticity generators of log- price and volatility are independent or are the same, two versions of the model are obtained with different leverage behaviors.

Here, the no- arbitrage and completeness properties of the models are rigorously studied. The no- arbitrage relation between futures and spot prices implies an analogous relation between futures and spot daily ranges. The long-memory features of the range-based volatility estimators are analyzed, and fractional cointegration is tested in a semi-parametric framework.

In particular, the no Prospect theory : An application to European option pricing. Empirical studies on quoted options highlight deviations from the theoretical model of Black and Scholes; this is due to different causes, such as assumptions regarding the price dynamics, markets frictions and investors' attitude toward risk.

Product price control using game theory : A case study of a fish price in the state of Terengganu. The increase in the price of goods is often a concern among the community. This is caused by factors that beyond of controlled such as a natural disaster, and others that cause the demand exceed the current supply. However, what is more concerning is the increase in price of goods due to the individual who raises the price in order to earn higher profits.

Therefore, to overcome this problem, a method of price controls using Game Theory is considered. The Game Theory realizing a form of observational on the action and effects that occur by an individual or group to maximize the utilization under certain circumstances. The study was conducted on prices of 14 fish commodities in the state of Terengganu and also to see the cooperation effect between players of commodity prices.

Data were analysed by using the software Gambit. The result shows that there is significant increase due to the influence of middlemen. The findings also shows that the price controls are applied at a set time, then it was applied to other times, prices are more stable and profitable returns to all parties can be maximized. Optimal execution with price impact under Cumulative Prospect Theory.

Optimal execution of a stock or portfolio has been widely studied in academia and in practice over the past decade, and minimizing transaction costs is a critical point. However, few researchers consider the psychological factors for the traders. What are traders truly concerned with - buying low in the paper accounts or buying lower compared to others?

We consider the optimal trading strategies in terms of the price impact and Cumulative Prospect Theory and identify some specific properties. Our analyses indicate that a large proportion of the execution volume is distributed at both ends of the transaction time.

But the trader's optimal strategies may not be implemented at the same transaction size and speed in different market environments. Pricing medicines: theory and practice, challenges and opportunities. The pricing of medicines has become one of the most hotly debated topics of recent times, with the pharmaceutical industry seemingly being attacked from all quarters.

From a company perspective, determining the price for each new product is more crucial than ever, given the present dearth of new drug introductions. But how are pricing strategies developed in practice? What is value-based pricing and how are financial models of return on investment constructed? What are the challenges faced in setting the price for a particular product, and how will scientific and environmental trends provide future pricing challenges or opportunities? On option pricing models in the presence of heavy tails.

We propose a modification of the option pricing framework derived by Borland which removes the possibilities for arbitrage within this framework. It turns out that such arbitrage possibilities arise due to an incorrect derivation of the martingale transformation in the non-Gaussian option models. Noble and Gruca , this issue provide useful insights into the pricing practices managers employ. Their findings indicate managerial pricing practices are heavily dominated by internal, cost-based approaches.

Particularly relevant is the absence of value-based pricing practices. Noble and Gruca's findings indicate that the emerging market orientation work has not connected to pricing practice.

Bridging the gap between theory and practice of transmission pricing. The authors describe some strategies for pricing transmission service.

Traditionally, wheeling prices have been postage stamp rates based on the level of megawatt demand; a related approach would assign grid costs to customers based on their respective shares of overall megawatt-miles. Innovative regulators have recently approved transmission rates based on opportunity cost of foregone capacity and the incremental costs of additional capacity needed to enable delivery.

Others determined prices designed to reflect short-run congestion costs on the grid.

This is a short book on the fundamental concepts of the no- arbitrage theory of pricing financial derivatives.

Its scope is limited to the general discrete setting of models for which the set of possible states is finite and so is the set of possible trading times--this includes the popular binomial tree model. This setting has the advantage of being fairly general while not requiring a sophisticated understanding of analysis at the graduate level.

Topics include understanding the several variants of " arbitrage ", the fundamental theorems of asset pricing in terms of martingale measures, and applications to forwards and futures. The authors' motivation is to present the material in a way that clarifies as much as possible why the often confusing basic facts are true. Therefore the ideas are organized from a mathematical point of view with the emphasis on understanding exactly what is under the hood and how it works.

Consumption-based macroeconomic models of asset pricing theory. Full Text Available The family of consumptionbased asset pricing models yields a stochastic discount factor proportional to the marginal rate of intertemporal substitution of consumption. In examining the empirical performance of this class of models, several puzzles are discovered. In this literature review we present the canonical model, the corresponding empirical tests, and different extensions to this model that propose a resolution of these puzzles.

EVT in electricity price modeling : extreme value theory not only on the extreme events. The extreme value theory EVT is commonly used in electricity and financial risk modeling. In this study, EVT was used to model the distribution of electricity prices. The model was built on the price formation in electricity auction markets. This paper reviewed the 3 main modeling approaches used to describe the distribution of electricity prices. The first approach is based on a stochastic model of the electricity price time series and uses this stochastic model to generate the given distribution.

The second approach involves electricity supply and demand factors that determine the price distribution. The third approach involves agent-based models which use simulation techniques to write down the price distribution. A fourth modeling approach was then proposed to describe the distribution of electricity prices. The new approach determines the distribution of electricity prices directly without knowing anything about the data generating process or market driving forces. Empirical data confirmed that the distribution of electricity prices have a generalized extreme value GEV distribution.

Arbitrage and Competition in Global Financial Regulation. Regulatory arbitrage in financial markets refers to a number of strategies that market participants use to avoid the reach of regulation, in particular by virtue of shifting trading abroad or else relocating activities or operations of financial institutions to other jurisdictions. If such risk-taking would be judged by market discipline instead of posing a risk to global financial stability, the main downside of regulatory competition could be restrained.

Within the boundaries of such a system, competition could then operate and contribute Policymakers worldwide are experimenting with remedies to respond to the phenomenon. I introduce the importance of an effective special A note on the theory of fast money flow dynamics.

The gauge theory of arbitrage was introduced by Ilinski in [K. Ilinskaia, K. Ilinski, Physics of finance: gauge modelling in non-equilibrium pricing Wiley, ]. The theory of fast money flow dynamics attempts to model the evolution of currency exchange rates and stock prices on short, e. It has been used to explain some of the heuristic trading rules, known as technical analysis, that are used by professional traders in the equity and foreign exchange markets. A critique of some of the underlying assumptions of the gauge theory of arbitrage was presented by Sornette in [D.

Sornette, Int. C 9, ]. In this paper, we present a critique of the theory of fast money flow dynamics, which was not examined by Sornette. We demonstrate that the choice of the input parameters used in [K. Ilinski, Physics of finance: gauge modelling in non-equilibrium pricing Wiley, ] results in sinusoidal oscillations of the exchange rate, in conflict with the results presented in [K.

We also find that the dynamics predicted by the theory are generally unstable in most realistic situations, with the exchange rate tending to zero or infinity exponentially.

Oil production cutbacks in recent years by OPEC members to stabilize price and to increase revenues warrant further empirical verification of the target revenue theory TRT.

We estimate a modified version of Griffin target revenue model using data from to The sample period, unlike previous investigations, includes phases of both price increase s and price decrease ss , thus providing a better framework for examining production behavior. The results, like the earlier study, are not supportive of the strict version of the TRT, however, evidence negative and significant elasticity of supply of the partial version are substantiated. Further empirical estimates do not support the competitive pricing model, hypothesizing a positive elasticity of supply.

OPEC's loss of market share and the drop in the share of oil-based energy should signal an adjustment in pricing and production strategies. Triangular arbitrage as an interaction among foreign exchange rates. We first show that there are in fact triangular arbitrage opportunities in the spot foreign exchange markets, analyzing the time dependence of the yen-dollar rate, the dollar-euro rate and the yen-euro rate. Next, we propose a model of foreign exchange rates with an interaction.

The model includes effects of triangular arbitrage transactions as an interaction among three rates. The model explains the actual data of the multiple foreign exchange rates well. Behavioral investment strategy matters: a statistical arbitrage approach. In this study, we employ a statistical arbitrage approach to demonstrate that momentum investment strategy tend to work better in periods longer than six months, a result different from findings in past literature.

Compared with standard parametric tests, the statistical arbitrage method produces more clearly that momentum strategies work only in longer formation and holding periods. Also they yield positive significant returns in an up market, but negative yet insignificant returns in a down A problematic issue in economic theory is the study of price determination.

Two distinct approaches to this difficult topic have been taken: i in Bertrand competition it is assumed sellers enter the market with a commitment to supply all demand forthcoming from buyers ii in Edgeworth competition sellers quote prices with no commitment to supply more than their competitive supply. Both these types of market contract struggle to provide credible pricemaking foundations for perfect competiti Most studies concerning OPEC's behavior were based on traditional market microstructure.

However, the assumptions about oil market structure are either very rigorous or rather fuzzy. This paper demonstrates the rationality and necessity of OPEC's price band policy by using the game theory. We conclude that OPEC has the incentive to limit its price within a specific range if the game period is sufficiently long. This incentive comes either from preference for long-term interest or from future expectations. In such a way, OPEC tries its best to maximize its profit with the quotaprice dual policy and plays a price stabilizing role in the future world oil market.

The message in North American energy prices. Serletis, A. How similar is the price behavior of North American natural gas, fuel oil, and power prices? Using current state-of-the-art econometric methodology, we explore the degree of shared trends across North American energy markets. Across these markets, there appear to be effective arbitraging mechanisms for the price of natural gas and fuel oil, but not for the price of electricity. Parameter estimation of electricity spot models from futures prices.

We consider a slight perturbation of the Schwartz-Smith model for the electricity futures prices and the resulting modified spot model. Using the martingale property of the modified price under the risk neutral measure, we derive the arbitrage free model for the spot and futures prices.

We estimate. The price terms in wheeling contracts very substantially, reflecting the differing conditions affecting the parties contracting for the service. These terms differ in the manner in which rates are calculated, the formulas used, and the philosophy underlying the accord. Nonfirm rates ranged from. The focus in this chapter is on cost-based rates, reflecting the fact that the vast majority of existing contracts are based on rate designs reflecting embedded costs.

This situation may change in the future, but, for now, this fact can't be ignored. An Investigation of Rational Decision Theory. The television game show The Price Is Right is used as a laboratory to conduct a preference-free test of rational decision theory in an environment with substantial economic incentives. It is found that contestants' strategies are transparently suboptimal. In response to this evidence, simple rules of thumb are developed that are shown to explain observed bidding patterns better than rational decision theory.

Further, learning during the show reduces the frequency of strategic errors. This is Have oil and gas prices got separated? This paper applies vector error correction models that show that oil and natural gas prices decoupled around Before , US and UK gas prices had a long-term equilibrium with crude prices to which gas prices always reverted after exogenous shocks.

Both US and UK gas prices adjusted to the crude oil price individually, and departure from the equilibrium gas price on one continent resulted in a similar departure on the other. After an exogenous shock, the adjustment between US and UK gas prices took approximately 20 weeks on average, and the convergence was mediated mainly by crude oil with a necessary condition that arbitrage across the Atlantic was possible. After , however, the UK gas price has remained integrated with oil price , but the US gas price decoupled from crude oil price and the European gas price , as the Atlantic arbitrage has halted.

The oversupply from shale gas production has not been mitigated by North American export, as there has been no liquefying and export capacity. Geographical aspects of geo- arbitrage : work in Canada and live in countries with low cost of living. The term geo- arbitrage means taking advantage of the difference in living costs between different geographic locations.

This paper focuses on geographical aspects of international geo- arbitrage based on differences in the cost of living from one country to another. More precisely, the paper shows the perspective for a Canadian student, volunteer, entrepreneur, IT person, or retiree with some sort of mobile income or savings can take advantage of price differences by traveling to other countries. The paper is based on world development indicators, which cover a wide range of criteria when moving to another country.

The data were collected for approximately countries and represent the following categories of criteria: cost of living economic factors , standard of living such as safety, health care, environmental issues , and personal preferences such as distance to home, Internet access or popularity of English language. The user input is required to rank or weight the importance of each of the criteria when moving to another country.

The results produce a list of the top suitable countries to practice geo- arbitrage. Another model allows the user to input weights for each criteria instead of ranks. The results from both models are mapped based on resulting suitability values. The top selected suitable countries are mapped, and the more specific information on each selected country is presented to the user, including the detailed cost of living, and current travel warning.

The application of option pricing theory to the evaluation of mining investment. A rational evaluation on an investment project forms the basis of a right investment decision-making. The discounted cash flow DCF for short method is usually used as a traditional evaluation method for a project investment. However, as the mining investment is influenced by many uncertainties, DCF method cannot take into account these uncertainties and often underestimates the value of an investment project.

Based on the option pricing theory of the modern financial assets, the characteristics of a real project investment are discussed, and the management option of mine managers and its pricing method are described. Game theory approach to use of non-commercial power plants under time-of-use pricing. There has been much research done on pricing theories for electric power utilities study. This paper employs the game theory approach for evaluating the impact of the introduction of customer owned NCP upon the pricing process when TOUP is used.

We have derived various interesting results from this analysis some of which are; the conflict between NCP customers and the supplier forces the supplier to reduce the price for NCP customers, also perception of the situation in which they are involved plays an important role in this conflict. The game model analysis presented in this paper provides us detailed quantitative information on electricity prices and on the ways of using NCP. This paper applies the dichotomous theory of choice by Zou a tothe analysis of investmentstrategies and security markets.

Issues concerning individualoptimality, approximate arbitrage ,capital market equilibrium, and Pareto efficiency are studied undervarious market conditions. Among the main. A game theory model for stabilizing price of chili: A case study. Chili is one of the important agricultural commodity in Indonesia because of its widely consumption by the Indonesian.

Chili becomes one of the commodities that experience price fluctuations and important cause of yearly inflation in Indonesia. The unstable price of chili is affected by the scarcity of the commodity in some months and the difference of the harvest season. This study proposes a model to solve the problem by considering the substitution of fresh chilies with dried chili. We propose the cooperative of chili's farmer as entities that process fresh chili into dry ones.

The existence of substitution products is expected to maintain the price stability chili. This research was conducted by taking a case study on chili commodity markets in Surakarta which consists of 19 traditional markets. This study aims to create a price stabilization scheme with product substitution using a game theory model.

There are 4 strategies proposed in game theory model to describe the relationship between producers and consumers. In this case, the producers are the farmers and the consumers are the trade market. A mixed strategy of was chosen to determine the optimal value among 4 strategies. From the calculation results obtained optimal value when doing a mixed strategy of IDR ,,, Full Text Available Both stochastic dominance and Omegaratio can be used to examine whether the market is efficient, whether there is any arbitrage opportunity in the market and whether there is any anomaly in the market.

In this paper, we first study the relationship between stochastic dominance and the Omega ratio. We extend the theory of risk measures by proving that the preference of second-order SD implies the preference of the corresponding Omega ratios only when the return threshold is less than the mean of the higher return asset.

On the other hand, the preference of the second-order RSD implies the preference of the corresponding Omega ratios only when the return threshold is larger than the mean of the smaller return asset. Nonetheless, first-order SD does imply Omega ratio dominance.

Thereafter, we apply the theory developed in this paper to examine the relationship between property size and property investment in the Hong Kong real estate market. We conclude that the Hong Kong real estate market is not efficient and there are expected arbitrage opportunities and anomalies in the Hong Kong real estate market. Our findings are useful for investors and policy makers in real estate. Theories of the price and quantity of physician services.

A synthesis and critique. In the traditional neoclassical model of supply and demand, prices determine the allocation of economic resources. The difficulty in applying this model to physician services is the rationing of resources directly by physicians themselves, eliminating the allocative function of prices.

Welfare consequences are appropriately judged in terms of efficiency and equity, not departures from the structural relationships implied by supply and demand. As interpreted here, both competitive theories and target-income theories of this market imply that physicians consider both their own welfare and the welfare of their patients in their decision-making. All consumer benefits and all producer costs are internalized by physicians.

They consequently have an incentive to obtain the maximum possible social benefit from the resources at their disposal, to the extent that they are implicitly allowed to share in the resulting social gains. The distribution of gains between patients and physicians is determined by professional ethics within bounds imposed by competitive forces.

Existing theories explaining security price clustering as well as clustering in the retail depositand mortgage markets are incompatible with the clustering in the corporate loan market. Wedevelop a new theoretical argument that the attitude of the lender toward the uncertaintyabout the quality of the borrower leads to the clustering of spreads. Our empirical resultssupport these arguments and we find that clustering increases with the degree of uncertaintybetween the lender and the borrower.

The rise and demise of the convertible arbitrage strategy. This article analyzes convertible arbitrage , one of the most successful hedge fund strategies. The aim of the strategy is to exploit underpricing of convertible bonds by taking a long position in a convertible and a short position in the underlying asset.

The authors find that convertible bonds are. Spatial and intertemporal arbitrage in the California natural gas transportation and storage network. Intertemporal and spatial price differentials should provide the necessary signals to allocate a commodity efficiently inside a network.

This dissertation investigates the extent to which decisions in the California natural gas transportation and storage system are taken with an eye on arbitrage opportunities. Daily data about flows into and out of storage facilities in California over and daily spreads on the NYMEX futures market are used to investigate whether the injection profile is consistent with the "supply-of-storage" curve first observed by Working for wheat.

Spatial price differentials between California and producing regions fluctuate throughout the year, even though spot prices at trading hubs across North America are highly correlated. In an analysis of "residual supply", gas volumes directed to California are examined for the influence of those fluctuations in locational differentials. Daily storage decisions in California do seem to be influenced by a daily price signal that combines the intertemporal spread and the locational basis between California and the Henry Hub, in addition to strong seasonal and weekly cycles.

The timing and magnitude of the response differs across storage facilities depending on the regulatory requirements they face and the type of customers they serve. In contrast, deviations in spatial price differentials from the levels dictated by relative seasonality in California versus competing regions do not trigger significant reallocations of flows into California.

Available data for estimation of both the supply-of-storage and residual-supply curves aggregate the behavior of many individuals whose motivations and attentiveness to prices vary. The resulting inventory and flow profiles differ from those that a social planner would choose to minimize operating costs throughout the network. Such optimal allocation is deduced from a quadratic programming model, calibrated to , that acknowledges relative seasonality.

It is organizedin two sections. The first one covers the unique price theory and the efficient markets hypothesis. In the second one, arbitrage conditions with ADRs are empirically evaluated. The objective is to prove the existence of price differentials between stocks and ADRs, which would allow investors to obtain a risk free return. It is organized in two sections. The objective is to prove the existence of price differentials between stocks and ADRs, which would allow.

Limits to Arbitrage in Sovereign Bonds. A queueing theory description of fat-tailed price returns in imperfect financial markets. In a financial market, for agents with long investment horizons or at times of severe market stress, it is often changes in the asset price that act as the trigger for transactions or shifts in investment position. This suggests the use of price thresholds to simulate agent behavior over much longer timescales than are currently used in models of order-books.

We show that many phenomena, routinely ignored in efficient market theory , can be systematically introduced into an otherwise efficient market, resulting in models that robustly replicate the most important stylized facts. We then demonstrate a close link between such threshold models and queueing theory , with large price changes corresponding to the busy periods of a single-server queue.

The distribution of the busy periods is known to have excess kurtosis and non-exponential decay under various assumptions on the queue parameters. Such an approach may prove useful in the development of mathematical models for rapid deleveraging and panics in financial markets, and the stress-testing of financial institutions. Lessons from game theory about healthcare system price inflation: evidence from a community-level case study.

Game theory is useful for identifying conditions under which individual stakeholders in a collective action problem interact in ways that are more cooperative and in the best interest of the collective. The literature applying game theory to healthcare markets predicts that when providers set prices for services autonomously and in a noncooperative fashion, the market will be susceptible to ongoing price inflation. We compare the traditional fee-for-service pricing framework with an alternative framework involving modified doctor, hospital and insurer pricing and incentive strategies.

While the fee-for-service framework generally allows providers to set prices autonomously, the alternative framework constrains providers to interact more cooperatively. We use community-level provider and insurer data to compare provider and insurer costs and patient wellness under the traditional and modified pricing frameworks.

The alternative pricing framework assumes i providers agree to manage all outpatient claims; ii the insurer agrees to manage all inpatient clams; and iii insurance premiums are tied to patients' healthy behaviours. Consistent with game theory predictions, the more cooperative alternative pricing framework benefits all parties by producing substantially lower administrative costs along with higher profit margins for the providers and the insurer.

With insurance premiums tied to consumers' risk-reducing behaviours, the cost of insurance likewise decreases for both the consumer and the insurer. Oil prices. Brownian motion or mean reversion? A study using a one year ahead density forecast criterion. For oil related investment appraisal, an accurate description of the evolving uncertainty in the oil price is essential.

For example, when using real option theory to value an investment, a density function for the future price of oil is central to the option valuation. The literature on oil pricing offers two views. The arbitrage pricing theory literature for oil suggests geometric Brownian motion and mean reversion models.

In addition to reflecting the volatility of the market, the density function of future prices should also incorporate the uncertainty due to price jumps, a common occurrence in the oil market. In this study, the accuracy of density forecasts for up to a year ahead is the major criterion for a comparison of a range of models of oil price behaviour, both those proposed in the literature and following from data analysis. The Kullbach Leibler information criterion is used to measure the accuracy of density forecasts.

Using two crude oil price series, Brent and West Texas Intermediate WTI representing the US market, we demonstrate that accurate density forecasts are achievable for up to nearly two years ahead using a mixture of two Gaussians innovation processes with GARCH and no mean reversion.

Full Text Available By reinterpreting the calibration of structural models, a reassessment of the importance of the input variables is undertaken. The analysis shows that volatility is the key parameter to any calibration exercise, by several orders of magnitude.

The methodology also eliminates the use of historic data to specify the default barrier, thereby leading to a full risk-neutral calibration. Subsequently, a new technique for identifying and hedging capital structure arbitrage opportunities is illustrated. The approach seeks to hedge the volatility risk, or vega, as opposed to the exposure from the underlying equity itself, or delta.

Direct and indirect techniques are being used to estimate economic consequences of proximity to existing or proposed public facilities. Abstract We present a model of a financial market in which naive diversification, based simply on portfolio size and obtained as a consequence of the law of large numbers, is distinguished from efficient diversification, based on mean-variance analysis. A microscopic model of triangular arbitrage. |

By riskless portfolio, he means a portfolio with totally predictable payoff. He then uses this argument to give the correct current price of the option which makes arbitrage impossible. Now I understand why the risk-neutral price of the call option is the only arbitrage-free price. If the call were overpriced an arbitrageur would long a replicating portfolio which easily exists in this model by some elementary linear algebra and short the call and if it were underpriced he or she would do the opposite.

In fact this is just the simplest version of the universal principle that the arbitrage-free value of any replicable contingent claim is just the discounted expectation of its payoff under the risk neutral probability measure. But I just don't understand Hull's principle I quoted above. There should be an obvious arbitrage opportunity if the return on a riskless portfolio doesn't match the risk-free rate, but since I have very poor finance intuition I'm from math background , I can't construct one by myself.

Forgive my ignorance but I still hope someone can help, thanks. You buy the cheaper, sell the more expensive, have a strictly positive cash-flow today and at maturity the cash-flows cancel out with certainty. This is a free lunch arbitrage.

It assumes that each investor will hold a unique portfolio with its own particular array of betas, as opposed to the identical "market portfolio". In some ways, the CAPM can be considered a "special case" of the APT in that the securities market line represents a single-factor model of the asset price, where beta is exposed to changes in value of the market.

A disadvantage of APT is that the selection and the number of factors to use in the model is ambiguous. Most academics use three to five factors to model returns, but the factors selected have not been empirically robust. Additionally, the APT can be seen as a "supply-side" model, since its beta coefficients reflect the sensitivity of the underlying asset to economic factors. Thus, factor shocks would cause structural changes in assets' expected returns, or in the case of stocks, in firms' profitabilities.

On the other side, the capital asset pricing model is considered a "demand side" model. Its results, although similar to those of the APT, arise from a maximization problem of each investor's utility function, and from the resulting market equilibrium investors are considered to be the "consumers" of the assets. As with the CAPM, the factor-specific betas are found via a linear regression of historical security returns on the factor in question.

Unlike the CAPM, the APT, however, does not itself reveal the identity of its priced factors - the number and nature of these factors is likely to change over time and between economies. As a result, this issue is essentially empirical in nature. Several a priori guidelines as to the characteristics required of potential factors are, however, suggested:.

Chen, Roll and Ross identified the following macro-economic factors as significant in explaining security returns: [3]. As a practical matter, indices or spot or futures market prices may be used in place of macro-economic factors, which are reported at low frequency e.
