It is well known from the literature that the introduction of financial constraints in economies with infinite-lived agents can be responsible for the occurrence of multiple equilibria and en- dogenous fluctuations. However, the question of the persistence of such phenomena when the constraints...

In this paper we propose a pension policy that would isolate the social security system from any financial crisis resulting from changes in population structure. This policy consists of linking social security benefits to the fertility behaviour of the individual. We present a theoretical...

In this paper, we explore a simple model which focuses on the joint role of workers’ heterogeneity and imperfect competition in the endogeneous formation of labor market equilibria. We show that, compared to the competitive case, imperfect competition leads to a misallocation of workers and to...

The labor market model is developed within an urban spatial context, where it is shown that effeciency-wage policies can lead to significant levels of involuntary unemployment. Commuting cost differences between workers and nonworkers tend to increase unemployment, and competition for land tends...

We consider a dual labor market with a continuum of heterogeneous workers differentiated by their ability of acquiring a specific skill. In the primary sector, jobs require firm-specific training and firms set efficiency wages. In the secondary sector, wages are competitive and no training is...

We show in a theoretical efficiency wage model where firms differ in monitoring intensity or in the effort intensity of their technologies that the impact of monitoring intensity on wages is ambiguous, a result that mirrors evidence from the empirical literature. We argue that to correctly...

In a game with rational expectations individuals refine their information with the information revealed by the strategies of other individuals: their elementary acts of other individuals at each state of the world. At a Nash of a game with rational expectations, the information of individuals is...

We reconsider the well-known result of Arrow (1953) that the set of equilibria of an economy with complete markets coincides with the one of an economy with sequentially complete markets. We show by means of two examples that this result is problematic when there exist multiple equilibrium...

For alternative specifications of an economy under uncertainty, we build a partially revealing Rational Expectations Equilibrium (REE). At equilibrium, no individual knows the state of the world or the quantities traded by other individuals. The combination of these partial revelation properties...

This paper analyses the impact of multiple competitive equilibria and complete markets in a simple general equilibrium model. A random selection from the equilibrium correspondence of a finite exchange economy defines probability distributions on equilibrium prices. Asset markets allow traders...
