Agent-based Computational Economics (ACE) is the computational study of economic processesmodeled as dynamic systems of interacting agents. This essay discusses the potentialuse of ACE modeling tools for the study of macroeconomic systems. Points are illustratedusing an ACE model of a two-sector...

Taking location as given, we study imperfect competition on a circular city. In Bertrandoligopoly, we identify price harmonics as a function of firm unit costs and locations. The sumof oligopoly profits is larger when costs and/or locations are more dispersed in the ‘dihedralmajorization’...

When adjustment costs are present, cyclical preference and technology heterogeneities in aproduct’s markets induce cycles in production. We exploit cyclic and dihedral groupinvariances in an industry’s cost technology to describe these patterns. We show whenequilibrium cyclical pricing and...

What an entrepreneurial opportunity is and from whence it comes are important issues for understanding how markets function and come into being.In addition to describing the forum held on the topic and summarizing the contributions of the articles that appear in the special issue, this article...

This paper discusses a two-sector neoclassical overlapping generationseconomy with intermediate and final goods in the spirit of Romer(1990). The risk averse agents engage in one of two alternative occupations:either firm-ownership in the intermediate goods sector, characterizedby monopolistic...

This paper investigates the effects of monopolistic competition onentrepreneurial riskRtaking in a general equilibrium model. In thiscontext, occupational choice of risk averse agents is biased towardsfirm ownership. In this case, the inefficiencies due to the presence ofnondiversifiable risk...

This paper derives a universal approximation result for theminimum fuzzy implication rule as well as a differentiable substitute function that allows fast optimization and function approximation with neuro-fuzzy networks.

In April 2003 the U.S. Federal Energy Regulatory Commission proposed a complicated marketdesign – the Wholesale Power Market Platform (WPMP) – for common adoption byall U.S. wholesale power markets. Versions of the WPMP have been implemented in NewEngland, New York, the mid-Atlantic states,...

Market concentration ratios are popular statistics for characterizing the extent of marketdominance in an imperfectly competitive market, but these ratios may not agree whencomparing two markets. Neither do they necessarily agree with the Herfindahl-Hirschman orentropy indices. This letter...

Our context involves Cournot oligopolists producing NM products at constant marginal costs when preferences are quasi-linear. We identify relationships between second moments of unit costs and second moments of firm-level production. For example, a larger variance in unit costs of a product...
