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 proposal involves the establishment of ‘welfare accounts’ for every person in a country. There are four accounts: a retirement account (covering pensions), an unemployment account (covering unemployment support), a human capital account (covering education and training), and a health...

This paper discusses how employment vouchers should depend on age in a simple overlapping generations model in which workers are either young or old. We find that young workers should receive higher vouchers as displacement of the old rises and as the deadweight loss from providing vouchers to...

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...

This Paper studies the internal commitment mechanisms or ‘personal rules’ (diets, exercise regimens, resolutions, moral or religious precepts, etc.) through which people seek to achieve self-control. Our theory is based on the idea of self-reputation over one’s willpower, which potentially...

This paper explores the optimal design of subsidies for hiring unemployed workers (‘employment vouchers’ for short) in the context of a simple macroeconomic model of the labour market. Focusing on the short-term and long-term effects of the vouchers on employment and unemployment, the...

The paper explores the employment implications of allowing people the opportunity of using a portion of their incapacity benefits to provide employment vouchers for employers that hire them. The analysis indicates that introducing this policy could increase employment, raise the incomes of...
