In this paper, we study the dynamics of legal rules in a model with two nation-states playing a non cooperative game. For each country, changing the legal system is a costly process. At the same time, the existence of different legal systems is also costly for all nation-states. We show that...

We develop a 2-country model of legal dynamics in which each country's social welfare depends generally on its actual law, its culturally ideal one, its technologically efficient one and the actual law of the other country. In our model, countries are better off when all these laws coincide....

We extend the analysis of Ball (2000) on near-rational expectations. We show that near-rational expectations imply nontrivial additional forecast errors and the degree of error depends on the monetary regime. Moreover, this scheme of expectations does not by itself give support to the New...

In this article, the authors investigate competitive firm behaviors in a two-firm environment assuming linear cost and demand functions. By introducing conjectural variations, they capture the different market structures as specific configurations of a more general model. Conjectural variations...

In this paper, we consider a T-stage linear model of Stackelberg oligopoly. First, we show geometrically and analytically that under the two conditions of linear market demand and identical constant marginal costs, the T-stage Stackelberg model reduces to a model where T oligopolies exploit...

In this paper, we consider a hierarchical oligopoly model, in which firms compete on quantities of an homogeneous product. We provide a proof and an interpretation that under the three necessary and sufficient conditions of linear aggregate demand, constant and identical marginal costs, the...

This paper examines the existence of Berge equilibrium. Colman et al. provide a theorem on the existence of this type of equilibrium in the paper [Colman, A. M., Körner, T. W., Musy, O. and Tazdaït, T. [2011] Mutual support in games: Some properties of Berge equilibria, J. Math. Psychol. 55,...
