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...

The striking geographical concentration of economic activities suggests that there are substantial benefits to agglomeration. The nature of those benefits remains unclear, however. In this Paper we take advantage of a new dataset to quantify the role of one of the main contenders: the matching...

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...

Large cities produce more output per capita than small cities. This may occur because more talented individuals sort into large cities, because large cities select more productive entrepreneurs and firms, or because of agglomeration economies. We develop a model of systems of cities that...

This paper uses two recent UK surveys to investigate labour market performance, the determinants of language proficiency, and the effect of language on earnings and employment probabilities of non-white immigrants. Our results show that language acquisition, employment probabilities, as well as...

We estimate a dynamic programming model of schooling decisions in which the degree of risk aversion can be inferred from schooling decisions. In our model, individuals are heterogeneous with respect to school and market abilities but homogeneous with respect to the degree of risk aversion. We...

There are few studies on occupational choices in Germany, and second-generation occupational choice and mobility is even less investigated. Such research is important because occupations determine success in the labour market. In a country like Germany occupations also reflect a general...

This paper investigates the human capital investments of migrants whose duration in the host country is limited, either by contract or by their own choice. The first part of the paper develops a model, distinguishing between migrants who immigrate on a fixed contract, and migrants who choose...

Two of the earliest inventions of a human capital-intensive technology were for the production of personal internal goods that enabled humans to derive more pleasure out of leisure, namely dance and music. I model the incentives to invent hobbies and to acquire hobby skills, and its implications...
