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

The aim of this paper is to empirically validate the agent-based macroeconomic model of Gaffeo et al. [2008]. We show that the microsimulated version of the model is able to replicate actual data with a satisfactory degree of precision. From a theoretical point of view, our validation approach...

The representative agent (RA) approach of the mainstream economics allows a rich analysis of intertemporal maximization; but it rules out the possibility of the analysis of complex interactions. It is the latter that are at the root of this and other crises. We argue that the RA approach is...
