We present an agent-based computational model in which bounded rational firms and workers trade on fully decentralized markets for final goods and labor by means of random matching protocols. The model replicates several macroeconomic phenomena regularly observed in the data, with aggregate...

Power law behavior is an emerging property of many economic models. In this paper we emphasize the fact that power law distributions are persistent but not time invariant. In fact, the scale and shape of the firms' size distribution fluctuate over time. In particular, on a log–log space, both...

This paper analyzes how the movements of the policy interest rate affect bank-relevant variables through changes in the composition of the loan portfolio. Using a computational approach that fully accounts for borrowers’ heterogeneity, we show how the variety of bank customers changes and how...
