Macroeconomic models are typically solved through the imposition of a top-down general equilibrium solution constraining agents' rational be- havior. This is customarily obtained by recurring, explicitly or not, to the Walrasian auctioneer (WA) artifice. In this paper we aim at contributing to...

This challenging book extends standard economic theory to take into account the presence of heterogeneity among economic agents. It argues for an approach to economic analysis which regards the economy as an interactive system with heterogeneous agents and not simply a system which treats...

In this paper we present the basics of a research program aimed at providing microfoundations to macroeconomic theory on the basis of computational agentbased adaptive descriptions of individual behavior. To exemplify our proposal, a simple prototype model of decentralized multi-market...

The firmly established evidence of right-skewness of the firms’ size distribution is generally modelled recurring to some variant of the Gibrat’s Law of Proportional Effects. In spite of its empirical success, this approach has been harshly criticized on a theoretical ground due to its lack...

In this paper we make use of firm-level data for a sample of European countries to prove the existence of a positive linear relationship between the mean and the variance of firms’ size, an empirical regularity known in mathematical biology as the Taylor power law. A computerized experiment is...
