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

The aim of this article is to analyse critically the definition of involuntary unemployment offered by Lindbeck and Snower in their insider-outsider model. Their category of involuntary unemployment will be shown to be broader than that of unemployment. Hence, with their definitional stance, it...

This paper investigates the effect of organizational and technological changes on job stability of different occupations in France. We first develop a basic matching model with endogenous job destsruction. It provides a structure to the empirical analysis, where we extensively exploit a unique...

We introduce an efficiency-wage mechanism into an innovation-driven growth model. Due to informational problems, the labour market is segmented and homogeneous workers may be employed either in a non-competitive intermediate sector or in a competitive research one. We analyse the impact that...

We analyze a unionized duopoly model to examine how unions affect the incentives for merger. We find that, once the union has the option to delegate, an increase in the union bargaining power can create incentives for the firms to merge.

We develop a model of wage determination with private information, in which te union has the option to delegate the wage bargaining to either surplus-maximizing delegates or to wage-maximizing delegates (such as senior union members). We show that the strike activity is greater whenever the...

We analyze to what extent skill heterogeneity in the labor market with different wage formation mechanisms can explain the features of the Spanish labor market. The model assumes two types of workers with differences in skills. Skilled labor sets wages in an efficiency way while unskilled labor...
