Guest-worker programs have been providing rapidly growing economies with millions of temporary foreign workers over the last couple of decades. With the duration of stay strictly limited by program rules in most of the host countries and wages paid to guest workers often set at sub-market...

Is entrepreneurial talent entirely innate or do people learn to become entrepreneurs? We extend Lucas's (1978) model of entrepreneurship to allow for the possibility that entrepreneurial talents may be acquired by watching other entrepreneurs in action. This model implies that areas with a...

We develop a two-country general equilibrium model where firms make separate choices about the location of R&D and high-tech production. There are two agglomeration forces: R&D spillovers and backward linkages associated with high-tech production. The latter tends to attract production to the...

We evaluate the role that cities play on individual productivity in China. First, we show that location explains a large share of nominal wage disparities. Second, even after controlling for individual and firms characteristics and instrumenting city characteristics, the estimated elasticity of...

Why do cities grow in population, surface area, and income per person? Which cities grow faster and why? To these questions, the urban growth literature has offered a variety of answers. Within an integrated framework, this chapter reviews key theories with implications for urban growth. It then...

Individual earnings are higher in bigger cities. We consider three reasons: spatial sorting of initially more productive workers, static advantages associated with workers' current location, and learning by working in big cities. Using rich administrative data for Spain, we find that workers in...

Where transport costs were falling, were the new economic geography forces for industry agglomeration and dispersion at work in the movement of industry in pre-1931 Britain? This Paper examines the issue empirically using a general model that nests the Heckscher-Ohlin factor endowment with new...

This paper is concerned with the influence of agglomeration economies on economic outcomes across British regions. The concentration of economic activity in one place can foster economic performance due to the reduction in transportation costs, the ready availability of customers and suppliers,...

Low corporate taxes can help attract new firms. This is the main mechanism underpinning the standard 'race-to-the-bottom' view of tax competition. A recent theoretical literature has qualified this view by formalizing the argument that agglomeration forces can reduce firms' sensitivity to tax...

The size distribution of cities in many countries follows some broadly regular patterns. Any good theory of city size distributions should (i) be able to account for this regularity, but also (ii) rely on a plausible economic mechanism and (iii) be consistent with other fundamental features of...
