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....

In this paper, we study the dynamics of legal convergence and the comparison between the different instruments of legal convergence based on cooperative strategies (i.e., harmonization and unification) or not. To study these questions we use a model with two nation-states which is inspired in...

The present paper proposes to interpret the differences in legal systems between common-law and civil- law nations as arising from the importance given to adjudication in comparison with statute laws. It focuses on the relative costs of legal change by adjudication (case law development) when...

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...
