In this note, we start to claim that established marriages can be heavily destabilized when the population of existing couples is enriched by the arrival of new candidates to marriage. Afterwards, we discuss briefly how stability concepts can be extended to account for entry and exit phenomena...

This paper builds a macroeconomic model of equilibrium unemployment in which firms persistently face difficulties in selling their production and this affects their decisions to create jobs. Due to search-frictins on the product market, equilibrium unemployment is a U-shaped function of the...

This paper aims at explaining the dynamics of labor markets in Spain, especially the high persistence of unemployment and the Beveridge curve. We build a stochastic dynamic general equilibrium matching model, which assumes failures in the matching between vacancies and unemployed. We calibrate...

We explain the positive correlation between union power and tax progressivity from a normative point of view by integrating labour market frictions and union power in an optimal taxation framework. We find that unions and redistributive taxation are complementary in the sense that they both...

The objective of this paper is to model explicitly the possibility to form temporary matching in a model of two-sided search. The agents (workers and employers) differ by their human quality endowment. In a search equilibrium agents form subintervals and are only matched to agents within their...

The objective of this paper is to analyze the relationship between bargaining organizational forms and the licensing of cost-reducing innovations, in order to assess the patent holders optimal policy as well as their welfare properties. Trading mechanisms based on bargaining models with...

This papers revisits the normative properties of search-matching economies when workers have concave utility functions. A general equilibrium framework is developed where agents are homogeneous and wages are bargained over. Assuming lump-sum taxation of profits, the optimal allocation of...

This paper characterizes optimal non-linear income taxation in an economy with a continuum of unobservable productivity levels and endogenous involuntary unemployment due to frictions in the labor markets. Redistributive taxation distorts labor demand and wages. Compared to the laissez-faire,...

The notion of frictional unemployment first arose in the writings of Beveridge, Pigou and Hicks. Why did it fail at the time to grow into a fully fledged theory ? Our answer is simple. This failure was due to the fact these economists were unwilling and/or unable to go beyond the then-prevailing...

This paper studies equilibrium unemployment in a two-region economy where homogeneous workers and jobs are free to move and the housing market clears. Because of the Internet, searching for a job in another region without first migrating there is nowadays much simpler than in the past....
