We completely characterize the set of second-best optimal "menus" of student-loan contracts in a simple economy with risky labour-market outcomes, adverse selection, moral hazard and risk aversion. The model combines structured student loans and an elementary optimal income-tax problem à la...

This paper offers a model of the interaction between composition of jobs and labour market regulation. Ex-post rent-sharing due to search frictions implies that ‘good’ jobs which have higher creation costs must pay higher wages. This wage differential distorts the composition of jobs, and in...

This paper offers and tests a theory of training whereby workers do not pay for general training they receive. The crucial ingredient in our model is that the current employer has superior information about the worker’s ability relative to other firms. This informational advantage gives the...

We propose to model individual educational investments as a rational decision, maximizing expected utility, conditional on some characteristics observed by the student, under the combined risks affecting future wages and schooling duration. Assuming that students' attitudes toward risk can be...

This paper presents an empirical study of birth-order and sibship sex-composition effects on educational achievement, and uses these variables as instruments to estimate returns to education, with the help of a rich set of individual data. Our sample includes more than 12,000 men and 10,000...

In the standard model of human capital with perfect labor markets, workers pay for general training. When labor market frictions compress the structure of wages, firms may invest in the general skills of their employees. The reason is that the distortion in the wage structure turns...

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. We show that when the assumption of perfectly competitive labour markets underlying this...
