In a 2-country and 3-period OLG model with education, we study the impact on international migration of the two sided characteristics of borders. Individuals must first "leave" their home country before "entering" the destination country. Indeed, each social planner chooses the static welfare...

In a 2-country monetary union, this paper studies a Stackelberg game be- tween the Central Banker and two symmetrical countries. The central banker chooses the money supply. In each country, there is a union who acts as a monopoly of labor supply. Firms are wage and price takers. We analyze the...

We study incentive-compatible labour contracts in the case where individual productivity, preference for leisure and time preference rate are unobservable by the principal in a two-period model. We first reduce this three-dimensional problem to a standard one-dimensional screening problem....

We analyse the consequences of a change of the characteristics of goods due to new information on the equilibrium of a pure exchange economy with n goods and m agents. Some changes of the characteristics of goods à la Lancaster have a positive effect on utility. In the general competitive...

We analyse the consequences of an increase of information (say as a consequence of the internet), on the equilibrium of a pure exchange economy with n goods and m agents. We assume that such an increase modifies the characteristics of goods la Lancaster and has a positive effect on utility. We...

Search models with posting and match-specific heterogeneity generate wage dispersion. Given K values for the match-specific variable, it is known that there are K reservation wages that could be posted, but generically never more than two actually are posted in equilibrium. What is unknown is...

This paper proposes a framework to analyze international migrations under uncertainty in theDiamond (1965) two period overlapping generations model with two countries. Considering arandom country-shock on both labor and capital, we show that each autarkic Cobb-Douglaseconomy converges to a...
