The theoretical impact of genetic diversity is ambiguous since it leads to costs and benefits at the collective level. In this paper, we assess empirically the connection between genetic diversity and the performance of sport teams. Focusing on football (soccer), we built a novel dataset of...

This paper examines how and why people migrate between two regions with asymmetric size. The agglomeration force comes from the scale economies in the provision of local public goods, whereas the dispersion force comes from congestion in consumption of public goods. Public goods considered...

We analyse the effects of migration on the production of public goods, income taxes, and on the welfare of residents in the sending and in the receiving country. Migration is based on income differences between countries. Different alternative scenarios are considered. In the first, we assume...

We analyze the effects of labor migration flows on income taxation between two countries (regions) differing by the size of their population and the level of productive efficiencies. Residents, otherwise identical, are heterogeneous because they incur different migration costs. Each resident...
