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...

In this paper we analyze the Ancona wholesale fish market (MERITAN) where transactions take place in three simultaneous Dutch auctions. Our objective is to characterize the behavior of market participants and, in particular, that of buyers in such a market structure. Our analysis shows that...

This document provides the initial report of the Simulation work package (Work Package 4,WP4) of the CATNETS project. It contains an analisys of the requirements for a simulation tool to be used in CATNETS and an evaluation of a number of grid and general purpose simulators with respect to the...

We present a simple model in which the transition from Malthusian stagnation to modern growth can occur. Agents are endowed with full control over their fertility but, differently from other studies, the degree of agents’ altruism which mainly affects fertility choices is allowed to change...
