learning schemes can be compared in terms of the consumption behaviour that they yield. We show that neither purely adaptive … learning, nor social learning based on imitation can ensure satisfactory consumption behaviours. By contrast, if the agents can … terms of its regularity, and its ability to improve performance (which is as a clear manifestation of learning). Our results …

This paper investigates the performances of an inflation targeting regime in a learning economy, whose functioning is … -- or heuristics -- while a continuous learning process governs the evolution of those simple rules. Departures from the … rational expectations equilibrium endogenously arise from those learning rules. Subsequently, the central bank implements an …

This chapter presents the methods and contributions of evolutionary approach to economic dynamics. First, we expose why economic dynamics can indeed be considered as evolutionary. Second, we discuss sources of diversity and selection mechanisms that drive these dynamics, in the context of...

We present the basic mechanisms of Genetic Algorithms and some significant applications of these algorithms in economics. The article also provides a representative reference list on this topic.

In this methodological work I explore the possibility of explicitly modelling expec-tations 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...

This contribution focuses on the simulation of the emergence and evolution of communities of practice, a concept brought forwards originally in sociology in the early 90’s by Lave and Wenger (1990) and Brown and Duguid (1991). In a first part, the main theoretical principles on which relies...

This article aims to test the relevance of learning through Genetic Algorithms (GA) and Learning Classifier Systems … simulations clearly show that learning is a source of technological and social efficiency. …

We show in this article how social learning gives rise to Walras equilibrium and why, in a … general setup, individual learning can effectively yield convergence to Cournot instead of Walras equilibrium. We illustrate …
