What is the impact on intra-national trade and regional economic outcomes when the quality and lane-capacity of an existing paved road network is expanded significantly? We investigate this question for the case of Turkey, which undertook a large-scale public investment in roads during the...

We present a simple model of a two-region economy in which undesirable concentration may occur. With freedom to choose where to live, individuals in this economy concentrate into one region in their pursuit of better life, and end up becoming worse off. We characterize the conditions under which...

Over the last two decades, the literature on comparative development has moved from country-level to within-country analyses. The questions asked have expanded, as economists have used satellite images of light density at night and other big spatial data to proxy for development at the desired...

Many studies of regional disparity in China have focused on the preferential policies received by the coastal provinces. We decomposed the location dummies in provincial growth regressions to obtain estimates of the effects of geography and policy on provincial growth rates in 1996-99. Their...

We exploit a series of discontinuities, at several population thresholds, in the allocation mechanism of federal transfers to municipal governments in Brazil to identify the causal effect of municipal spending on local labor markets, using a 'fuzzy' regression discontinuity design. Our estimates...

In this chapter we analyze immigration and its effect on urban and regional economies focusing on productivity and labor markets. While immigration policies are typically national, the effects of international migrants are often more easily identified on local economies. The reason is that their...

We use a newly assembled sample of 1,503 regions from 82 countries to compare the speed of per capita income convergence within and across countries. Regional growth is shaped by similar factors as national growth, such as geography and human capital. Regional convergence is about 2.5% per year,...

We investigate the role of deeply-rooted pre-colonial ethnic institutions in shaping comparative regional development within African countries. We combine information on the spatial distribution of ethnicities before colonization with regional variation in contemporary economic performance, as...

Aggregate and more micro data on trade between the U.S., Canada, and Mexico are used to attempt to assess the early effects of Mexican entry into NAFTA. Although the fraction of Mexican trade with the U.S. and Canada has risen sharply, a number of factors have contributed to this result. Mexican...

The possibility of a single currency for the Mercosur countries was raised by Argentine President Menem in December 1997 and again at the regional summit this past June. This paper argues that whether Mercosur needs a common currency depends on what kind of integrated regional market its...
