In 1958 Jacob Mincer pioneered an important approach to understand earnings distribution. In the years since Mincer?s seminal work, he as well as his students and colleagues extended the original human capital model, reaching important conclusions about a whole array of observations pertaining...

Becker?s theory of human capital predicts that minimum wages should reduce training investments for affected workers because they prevent these workers from taking wage cuts necessary to finance training. In contrast, in noncompetitive labor markets, minimum wages tend to increase training of...

Employment protection systems are known to generate significant distortions in firms? hiring and firing decisions. We know much less about the impact of these regulations on worker effort. The goal of this paper is to fill in this gap and in particular to assess whether the provision of...

This article is an idiosyncratic survey of the insider-outsider theory, describing the vision underlying the theory, and evaluating salient contributions to the literature in the light of this vision. We also indicate what appear to have been dead-ends and red herrings in past research. The...

Whereas the standard modern theories of unemployment were developed in the context of a single sector labour market, this paper presents a survey of how these theories can be integrated into a dual labour market setting. This approach dichotomises the labour market into two sectors, a primary...

This paper analyses the impact of labor market conditions on a firm's incentive to train its workers. In an equilibrium model of the labor market in which firms use both untrained and in-house trained workers, we show that the incidence of training increases with the tightness of the labor...

External certification of workplace skills obtained through on-the-job training is widespread in many countries. This may indicate that training is financed by workers, and certification serves to assure the quality of the training offered by the firm. However, other evidence shows that general...

When workers' investments in firm-specific skills are non-contractible underinvestment may occur because of holdup. Up-or-out contracts can potentially solve this problem by limiting the firm's scope for opportunistic behavior. The downside of such contracts is that a worker who does not make...
