An enormous number of empirical papers have estimated technical efficiency, the distance of firms inside a frontier, following the model of Farrell (1957). We propose a theory that explains the distance these empirical papers seek to measure. The theory is based on the idea that workers can...

We investigate the sources of differences in school performance between students of different races by focusing on identity issues. We find that having a higher percentage of same-race friends has a positive effect of white teenagers’ test score while having a negative effect on blacks’ test...

Parents with higher education levels have children with higher education levels. Is this because parental education actually changes the outcomes of children, suggesting an important spillover of education policies, or is it merely that more able individuals who have higher education also have...

Estimates of the effect of education on GDP (the social return to education) have been hard to reconcile with micro-evidence on the private return. We present a simple explanation that combines two ideas: imperfect substitution between worker types and endogenous skill-biased technological...

Switzerland has experienced a substantial influx of immigrants over the 50 years since World War II, to the extent that it now has one of the highest share of foreigners in population among OECD countries. This paper analyses Switzerland’s experience of migration, centring on two main issues:...

A Welfare-to-Work (WTW) program is a mix of government expenditures on various labor market policies targeted to the unemployed (e.g., unemployment insurance, job search monitoring, social assistance, wage subsidies). This paper provides a dynamic principal-agent framework suitable for analyzing...

We discuss how a schooling system’s structure may imply that private school enrolment leads to worse subsequent performance in further education or in the labour market, and we seek evidence of such phenomena in Italian data. If students differ not only in terms of their families’ ability to...

This Paper develops a descriptive methodology for the analysis of wage growth of immigrants, based on human capital theory. The sources of the wage growth are: (i) the rise of the return to imported human capital; (ii) the impact of accumulated experience in the host country; and, (iii) the...

In the past century, more people have perished from famine than from the two World Wars combined. Many more were exposed to famine and survived. Yet we know almost nothing about the long run impact of famine on these survivors. This paper addresses this question by estimating the effect of...

Typically, laboratory experiments suffer from homogeneous subject pools and self-selection biases. The usefulness of survey data is limited by measurement error and by the questionability of their behavioural relevance. Here we present a method integrating interactive experiments and...
