Mean-variance criteria remain prevalent in multi-period problems, and yet not much is known about their dynamically optimal policies. We provide a fully analytical characterization of the optimal dynamic mean-variance portfolios within a general incomplete-market economy, and recover a simple...

This paper examines hierarchies’ role in the organization of human-capital-intensive production. We develop an equilibrium model of hierarchical organization, then provide empirical evidence using confidential data on thousands of law offices from the 1992 Census of Services. We show how the...

There are relevant gender differences in the labour-market status of health sciences graduates in Spain: (i) female physicians have lower participation rates than male physicians plus they are subject to higher occupational mismatch, and (ii) moonlighting is more frequent among male physicians....

In this paper, we propose an alternative methodology for ranking hospitals based on the choices of Medical School graduates over hospital training vacancies. Our methodology is therefore a revealed preference approach. Our methodology for measuring relative hospital quality has the following...

This paper provides some evidence that the division of labour is limited by the extent of the (local) market. We first propose a theoretical model. Its main prediction is that scarce occupations are over-represented in large cities. Using census data for French cities, we then provide strong...

There is a considerable empirical literature which compares wage levels of workers who have studied at secondary vocational schools with wages of workers who took academic schooling. In general, vocational education does not lead to higher wages. In some countries where labour markets are...

This paper presents a modified and improved methodology for the decomposition of wage differentials between two groups of workers into an endowment component and a discrimination component. The standard decomposition technique does not take into account different probabilities of entering the...

The use of self assessed health status as a measure of health is common in empirical research. We analyse a unique Australian survey in which a random sub-sample of respondents answer a standard self assessed health question twice – before and after an additional set of health related...

A relevant question for the organization of large scale research assessments is whether bibliometric evaluation and informed peer review where reviewers know where the work was published, yield similar results. It would suggest, for instance, that less costly bibliometric evaluation might - at...

The inequality dataset compiled in the 1990s by the World Bank and extended by the UN has been both widely used and strongly criticized. The criticisms raise questions about conclusions drawn from secondary inequality datasets in general. We develop techniques to deal with national and...
