This paper describes an agent-based model of exchange and uses it to illustrate the modelling framework offered by John Holland in his book on emergence and to propagate a hypothesis about the relationship between levels of exchange and the diversity of shadow prices. On both counts, the model...

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....

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...

As the world's telecommunication providers privatize, governments turn toward regulatory mechanisms to resolve interconnection disputes. Following provisions of the World Trade Organization agreement, these decisions are supposed to be decided on the basis of "cost;" however, the language...

Many optimization methods are available at the present time. The software that implements a particular method may not be available to all users or the software may require a compiler not readily available to all users. The software may require extensive modifications before it can run on a...

Since the beginning of this century, the normal distribution has played a central role in the mathematical finance literature. However, major drawbacks insight this assumption rely in the absence of closed form expressions for both its cumulative and probability density functions. Additionally,...

In his monograph The Conquest of American Inflation, Sargent (1999) points out the perils of econometric policy evaluation of the Theil-Tinbergen tradition wherein one estimates a reduced form econometric model of the economy and subjects it to control. If the model is misspecified, as is...

The work studies the properties of a coordination game in which agents repeatedly compete to be in the population minority. The game reflects some essential features of those economic situations in which positive rewards are assigned to individuals who behave in opposition to the modal behavior...

On last yearÌs conference in Barcelona the authors presented an innovative expectation formation hypothesis. The assumption of fully rational agents is rejected and replaced by a bounded rationality approach that is modelled by means of a fuzzy rule-base. These rules as well as their components...
