This paper proposes an aspiration-based model for (anonymous) cooperation where a large population of agents are re-matched every period to playa Prisoner's Dilemma. At each point in time, agents hold a certain common aspiration level which is updated on the basis of population-average...

A model of "satisficing" behavior in the repeated Prisoners Dilemma is studied. Each player has an aspiration at each date, and takes an action. [S]he switches from the action played in the previous period only if the achieved payoff fell below the aspiration level (with a probability that...

The aim of this paper is to show the relation among equilibria in models with different levels of rationality. The different levels of rationality are defined in terms of the number of iterations that a player can perform with a simple rule for updating beliefs. It is shown that the rule...

Competition has long been regarded as productivity enhancing. Understanding the mechanism by which competition affects innovation and productivity is therefore an important topic for economic policy. The main contribution of this paper is to disentangle the relationship between competition and...

Here I provide a model that gives some insights regarding questions about actual economic behavior. I take as a source for stylized facts the experiments conducted by Marimón and Sunder as reported in Econometrica, 1993, in which it is shown that people initially do not behave according to 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. 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...

In this paper we analyze firms' ability to tacitly collude on pricesin an infinitely repeated duopoly game of vertical productdifferentiation. We show that firms collude if and only if their discountfactor is high enough, i.e. if they value future profits sufficiently. We alsoshow that a lower...

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, present a calibrated model of life-cycle occupation and investment decisions where households choose between paid work and entrepreneurship and conditional on the latter how much of their savings to invest in their business. The returns to entrepreneurial activity are modeled...

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...
