This paper develops and tests a heterogeneous agents model for the option market. Our agents have differing beliefs about the level of volatility of the underlying stock index and trade accordingly. We consider two types of agents: fundamentalists, who are assumed to expect the conditional volatility to return to the unconditional volatility, and chartists who respond solely to noise from the l...

The Sato process model for option prices is expanded to accomodate credit considerations by incorporating a single jump to default occuring at an independent random time with a Weibull distribution. Explicit formulas, in this context, for the bid and ask prices of two price economies that price residual risks to levels of risk acceptability are then derived. Liquidity considerations are thereby...

Economic agents have the possibility to fund the protection of environmental public goods, such as natural ecosystems and biodiversity, facing unknown risks of collapse, which could help to back them up. On the base of the prediction markets, which meet with a degree of success since their introduction, we propose an evolutionary model of an option fund market for the threshold environmental pu...

We call markets in which intermediaries sell networks of suppliers to consumers who are uncertain about their needs "option demand markets." In these markets, suppliers may grant the intermediaries discounts in order to be admitted to their networks. We derive a measure of each supplier's market power within the network; the measure is based on the additional ex ante expected utility consumers ...

pro-market economists usually present “competition” as the only solution of government’s inefficiencies. therefore, having given too much credence to the private sector in economy, they choose market strategy rather than state strategy in economic policies, prizing market choice above state choice, thereby advising strongly privatization policies in the economic system in order to inject ration...

In this paper, we examine an exchange economy with a financial market composed of three assets: a share of a stock, an European call option written on the stock, and a riskless bond. The financial market is assumed to be incomplete and the option is not a redundant asset. In such a case the construction of a riskless hedge-portfolio to valuate the option is unfeasible and therefore the pricing ...

This paper describes how to evaluate a long-term fixed priced material procurement contract versus spot purchases. We model the long-term contract as a real option. In the financial world, option pricing is based on the assumption that the market is complete and frictionless. This assumption is usually too strong when it comes to pricing real options. For example, both the option and its underl...

The efficient market hypothesis based primarily on the statistical principle of Bayesian inference has been proved to be only a special-case scenario. The generalized financial market, modeled as a binary, stochastic system capable of attaining one of two possible states (High  1, Low  0) with finite probabilities, is shown to reach efficient equilibrium with p . M = p if and only if the tran...

Taking advantage of a unique corporate bond transaction dataset from the National Association of Securities Dealers (NASD), this paper investigates whether information-based trading takes place in the high-yield corporate bond market, and how firm-specific information flow across related securities, including stocks, options and corporate bonds. Differing from previous studies, I find that curr...
