We analyse the dynamics resulting from social learning in a simple general equilibrium (GE) model, whose structure is similar to the one underlying macroeconomic models of the New Macroeconomic Synthesis. The economy is composed by households and firms who exchange labour and consumption goods...

This article questions the rather pessimistic conclusions of Allen and Carroll (2001) about the ability of consumer to learn the optimal buffer-stock based consumption rule. To this aim, we develop an agent based model where alternative learning schemes can be compared in terms of the...

The modelling of networks formation has recently became the object of an increasing interest in economics. One of the important issues raised in this literature is the one of networks efficiency. Nevertheless, for non trivial payoff functions, searching for efficient network structures turns out...

This article is dedicated to the analysis of the first innovation survey of the Tunisian firms. Starting from basic mechanisms of innovation processes and existing results on other developing countries, we test a set of assumptions on the characteristics of innovating firms in a developing...

We test the robustness of the main growth mechanisms of the original Aghion & Howitt model by relaxing two central assumptions: the homogeneity of the agents and perfect foresight. To this end, we introduce boundedly rational firms in the R&D sector that are capable of learning. Our first...

In this methodological work I explore the possibility of explicitly modelling expectations conditioning the R&D decisions of firms. In order to isolate this problem from the controversies of cognitive science, I propose a black box strategy through the concept of internal model. The last part of...

This article aims to test the relevance of learning through Genetic Algorithms (GA) and Learning Classifier Systems (LCS), in opposition with fixed R&D rules, in a simplified version of the evolutionary industry model of Nelson and Winter. These three R&D strategies are compared from the points...

In a preceding article we have studied the Communities of Practice and their conditions of emergence using an Agent based model of a set of agents facing a continuous flow of problems. We center now our analysis on the performance of this organizational structure in comparison with a two-level...
