Consider an evolutionary context where a given number of quantity-setting oligopolists tend to mimic successful behavior, occasionally experimenting with some small probability. In this context, it is shown that the unique long-run outcome of the process has all firms playing Walrasian, i.e.,...

We study a market for a homogeneous good in which firms adjust theirproduction decisions on the basis of imitation, learning from own experience, and local experimentation.For any fixed set of firms (more than one), long run behavior settles on a symmetric marginal-cost pricingequlibrium. When...

This paper analyzes an evolutionary model where agents are locally matched to playa coordination game and can adjust both their strategy and location. Their decisions are subject to friction, so that an agent who migrates to a different location may be unable to adjust her strategy optimally to...

This paper introduces expectations into the framework of evolutionary games. On the one hand, (myopic) players are assumed to behave optimally according to the expectations they hold at each point of the process. On the other hand, expectations themselves are continuously updated according to...

In this paper, we study the return to human capital variables for wages of workers observed in Tunisian matched worker-firm data in 1999. We develop a new method based on multivariate analysis of firm characteristics, which allows us most of the benefits obtained by introducing firm dummies in...

We study a dynamic process where agents in a network interact in a Prisoner’s Dilemma. The network not only mediates interactions, but also information: agents learn from their own experience and that of their neighbors in the network about the past behavior of others. Each agent can only...

From Tunisian matched worker-firm data in 1999, we study the returns to human capital for workers observed in two leading manufacturing sectors. Workers in the mechanical and electrical industries (IMMEE) benefit from higher returns to human capital than their counterparts in the...

In this paper, we study the return to human capital variables for wages of workers observed in Tunisian matched worker-firm data in 1999. This reveals us how returns to human capital in a Less Developed Country like Tunisia may differ from the industrial countries usually studied with matched...

In this paper, we draw some lessons from the Tunisian experience of social reforms and associated civil conflict. Our main interest is the riots that occurred after subsidy cuts and the attempts at substitution of price subsidies by direct cash transfers. We propose new welfare indicators apt to...

We study the relationship of wages and education and training practices in Morocco in a context of trade and liberalisation reforms in a matched worker-firm data of eight exporting firms in two industrial sectors: Metallurgical-Electrical industries and Textile-Clothing. We find that the...
