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...

We survey and assess the literature on the positive and negative effects of ethnic diversity on economic policies and outcomes. Our focus is on both focus both cities in developed countries (the US) and villages in developing countries. We also consider the endogenous formation of political...

This paper is about the spending choices of youth, with a particular focus on how the demand for cigarettes, alcohol and marijuana are influenced by changes in the prices of other products. Youth tend to have small incomes and limited wants, with the result that many students spend the bulk of...

We assess substitutable and complementary relationships among eight national advertising media classes, as well as the magnitude of their own-price elasticities. We use a translog demand model, whose parameters we estimate by three-stage least squares, based on 1960-94 annual U.S. data.We find...

Several theories suggest that pay raises below a reference point will reduce job performance. Final offer arbitration for police unions provides a unique opportunity to examine these theories, as the police officers either receive their requested wage or receive a lower one. In the months after...

The federal system for distributing student financial aid rivals the tax code in its complexity. Both have been a source of frustration and a focus of reform efforts for decades, yet the complexity of the student aid system has received comparatively little attention from economists. We describe...

Behavioral Economics is the combination of psychology and economics that investigates what happens in markets in which some of the agents display human limitations and complications. We begin with a preliminary question about relevance. Does some combination of market forces, learning and...

In this paper we construct a supply function of university education, i.e. the dependence of the supply (the number of places for students) on its price, i.e. on the revenue of university (either from scholarship or from state support) per student. We derive our results from an optimization...

We analyze the structure of a society driven by power relations. Our model has an exogenous power relation over the set of coalitions of agents. Agents determine the social order by forming coalitions. The power relations determine the ranking of agents in society for any social order. We study...

This paper presents a dynamic model of labor/leisure, consumption/saving and annuity decisions over the life cycle. Such a dynamic model provides a framework for considering important policy experiments related to the reforms in Social Security. We address the role of labor supply in a life cyle...
