The ¿beneficial brain drain¿ hypothesis suggests that skilled migration can be good for a sending country because the incentives it creates for training increase that country¿s supply of skilled labour. To work, this hypothesis requires that the degree of screening of migrants by the host...

This paper examines the relation between ambition, as a form of dynamic human capital, and the escalator role of high order metropolitan regions, as originally identified by Fielding (1989). It argues that occupational progression in such places particularly depends on concentrations both of...

This paper examines the relation between ambition, as a form of dynamic human capital, and the escalator role of high-order metropolitan regions, as originally identified by A. J. Fielding. It argues that occupational progression in such places particularly depends on concentrations both of...

In this paper, using the framework of a Roy theoretical model, we examine the performance of return migrants in Albania. We ask two main questions: (i) Had they chosen not to migrate, what would be the performance of return migrants compared to the non-migrants? and (ii) What would be the...

There is widespread concern currently that some ethnic minority communities within Britain, especially Muslim, are not following the stereotypical immigrant path of economic and cultural assimilation into British society. Indeed, many seem to have the impression that differences between Muslims...

This brief essay provides a selective discussion of how in recent years economists in the neoclassical tradition have addressed the questions whether and how immigration affects native workers’ labour market outcomes. In particular, it discusses: the distinction between the displacement,...

In the urban resurgence accompanying the growth of the knowledge economy, second-order cities appear to be losing out to the principal city, especially where the latter is much larger and benefits from substantially greater agglomeration economies. The view that any city can make itself...

Ethnic inventors play important roles in US innovation systems, especially in high-tech regions like Silicon Valley. Do ‘ethnicity-innovation’ channels exist elsewhere? This paper investigates, using a new panel of UK patents microdata. In theory, ethnicity might affect positively innovation...

Following Grossman and Rossi-Hansberg (2008) we present a model in which tasks of varying complexity are matched to workers of varying skill in order to develop and test predictions regarding the effects of immigration and offshoring on US native-born workers. We find that immigrant and...

The skill gap in geographical mobility is entirely driven by workers who report moving for a new job. A natural explanation lies in the large expected surplus accruing to skilled job matches. Just as large surpluses ease the frictions which impede job search in general, they also help overcome...
