We propose a test that uses information on workers’ mobility, wages and firms’ profits to identify the sign and strength of assortative matching. The basic intuition underlying our empirical strategy is that, in the presence of positive (negative) assortative matching, good workers are more...

In labor markets with worker and firm heterogeneity, the matching between firms and workers may be assortative, meaning that the most productive workers and firms team up. We investigate this with longitudinal population-wide matched employer-employee data from Portugal. Using dynamic panel data...

Hellerstein and Neumark (1999) developed a straightforward method to detect wage discrimination using matched employer-employee data. In this paper a new method to measure wage discrimination is proposed, that builds on the ideas first developed by Hellerstein and Neumark. It has four main...

The CFL programme has been introduced in 1985 to improve the youths occupational chances. It provides the employers some incentive to recruit young workers by reducing both the labour and the firing costs relative to those they would bear by recruiting older workers. Following the literature,...

The availability of a flexible labour force might influence adjustment decisions regarding the rigid part of the labour force. To test this idea, we contrast the use of trainees (fixed-term contracts) and normal-contract workers (open-end contracts) when a reform made it more costly to use...

This paper investigates the role that idiosyncratic uncertainty plays in shaping social preferences over the degree of labor market flexibility, in a general equilibrium model of dynamic labor demand where the productivity of firms evolves over time as a Geometric Brownian motion. A key result...

Labor market reforms increasing flexibility at the margin have been recently paying out in terms of employment growth. This paper argues that two-tier labor market reforms have a transitional honeymoon, job creating effect. In a dynamic model of labor demand under uncertainty, the paper predicts...

In this paper I propose and estimate an equilibrium search model using matched employer-employee data to study the extent to which wage differentials between men and women can be explained by differences in productivity, disparities in friction patterns, segregation or wage discrimination. The...
