We study two different modes of social influence on human or artificial decision makers operating in complex environments. One is through emulation of social values, and the other is through social recommendations for specific actions. In an economic environment where agents make trade and...

Background This paper is a continuation of our investigation of the paradox of technical analysis in the stock market (Fyfe, Marney and Tarbert (1999), Marney et. al (2000)). The Efficient Markets Hypothesis (hereafter the EMH) holds that there should be no discernible pattern in share price...

For many environmental problems regulators are uncertain about both the costs of abatement and the stock-related damages. For example, governments have imperfect information about damages caused by greenhouse gas stocks, and also about the costs of abating greenhouse gas emissions. They acquire...

In this paper, we propose use of the influence diagram for stock portfolio selection. We use an algorithm that applies the mutual information as the metric to guide the refinement of the influence diagram. We applied the algorithm to the conceptual refinement of the influence diagram. We tested...

Anderson's papers describe a method for solving linear saddle point models. The numerical implementation of the algorithm has proved useful in a wide array of applications including analyzing linear perfect foresight models, and providing initial solutions and asymptotic constraints for...

This paper explores the dynamics of the U.S. hog market with three different dynamic models that are distinguished only by their assumptions with regard to market participants' expectations of future prices. The first model assumes that all the producers in the market have rational expectations....

In this paper, we specify a theoretical dynamic oligopoly model with regard to asymmetric firms. We then estimate a structural dynamic model of demand and pricing relations for the semiconductor industry. Using quarterly firm-level output and cost data as well as industry prices from 1974 to...

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...

The literature on multi-agent models up until recently has been mainly concerned with the price dynamics in a setting where agents are allowed to switch between a finite number of strategies.In reality, however, we would expect a high degree of heterogeneity, such that few belief types will...

The paper presents a correctnes proof as well as an implementation in maple of an algorithm to compute the value function of infinite horizon optimal control problems with a single state variable. It proceeds as follows: step1:compute candidates for equilibria(from the HJB); step2:for each...
