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...

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.

We study the effects of deposit insurance and observability of previous actions on the emergence of bank runs by means of a controlled laboratory experiment. We consider three depositors in the line of a bank, who decide between withdrawing or keeping their money deposited. We have three...

The predicted labor supply responses to variations in wages and prices are important for discussions of the economic efficiency of taxes and subsidies, and their extent may be also relevant to the analysis of economic fluctuations. This paper presents new estimates of the wage intertemporal...

The main advantages of a laboratory financial market with respect to field data are: (i) it allows us a perfect monitoring of the available information to each subject at any moment in time, and (ii) it gives us the possibility of recording subjects' trading activity in the market. In our...

This paper considers the use of loyalty inducing discounts in vertical supply chains. An upstream manufacturer and a competitive fringe sell differentiated products to a retailer who has private information about the level of stochastic demand. We provide an analysis of the market outcomes when...
