This paper considers Nash equilibria of a game played by two populations. Stability of the mixed equilibria is diacU8aed for a wide class of differential systems describing the evolutionary dynamics of behavior. The main property of the Systems under consideration is that every Nash equilibrium...

We study an income tax enforcement problem using a principal agent model where the government sets the tax and inspection functions. These functions are announced to the agents and there is no commitment problem. The penalty function for dishonest taxpayers is given exogenously and must satisfy...

This paper deals with the existence and properties of the demand correspondence when agents' preferences are pseudotransitive. It is shown that a consumption plan belongs to the demand mapping if and only if it is a maximizer of a real-valued weak utility function. Further properties, as...

Two solution concepts have been proposed for bargaining problems with claims, namely, the proportional solution, introduced by Chun & Thomson (1992), and the extended claim-egalitarian solution, [see Bossert (1993) and Marco (1993)]. Neither of these solutions exhaust all possible gains from...

This paper analyzes how learning considerations may influence the pricing behavior of a duopoly facing demand uncertainty. We consider a symmetric duopoly game with product differentiation where firms have imperfect information about some parameters of the market demands. Firm learn about these...

Following the work of Bandyopadhyay and Sengupta, we analyze the rationalization of a choice function in terms of the revealed preference but in a more general context: choice sets with a continuum of alternatives. Firstly it is proved that some results which are verified in the finite case are...

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...

This paper proposes a test statistic for discriminating between two partly non linear regression models whose parametric components are non-nested. The statistic has the form of a J-test based on a parameter which artificially nests the null and alternative hypotheses. We study in detail the...

Since the 1970's most industrialized countries have undertaken massiveinvestment in computers and information technology (IT). Several stylizedfacts emerge from the empirical studies, see Landauer, 1993. In particular,they have found that this investment has not lead to a general increase...

In this paper we study the optimal trade policy in an oligopolistic market with a given number of quantity-setter firms. It is shown that under no fixed costs, the optimal trade policy displays certain characteristics but under fixed costs most of these characteristics no Longer hold.
