In the last decades, the OECD labor markets faced important labor supply changes with the arrival of women and the cohorts of the baby-boom. Using a survey where workers declare their true employment experience, this paper argues that these supply trends imply more inexperienced workers. It then...

We analyse an equilibrium labour market with on-the-job search and experience effects (where workers learn-by-doing). The analysis yields a standard Mincer wage equation with worker fixed effects and endogenously determined firm fixed effects. It shows that learning-by-doing increases...

This paper constructs a theory of the coexistence of fixed-term and permanent employment contracts in an environment with ex-ante identical workers and employers. Workers under fixed-term contracts can be dismissed at no cost while permanent employees enjoy labor protection. In a labor market...

This paper presents a general-equilibrium model of endogenous skilled-biased technological change and matching unemployment in a disaggregated economy. We simultaneously endogenise both the direction and pace of technological change as well as the unemployment rates. We show that an increase in...

We extend the standard quality-ladder model with heterogeneous workers by including efficiency wages and unions. We find that higher union bargaining power leads to a negative relationship between growth and unemployment. An increase in the supply of human capital, however, on the one hand...

This paper analyzes the role of the period length in a search model of the labor market and argues that it has profound implications for the market equilibrium. In the model, job offers and job destruction shocks arrive according to a Poisson process in continuous time, but institutional factors...
