Lumpiness of production factors within a country might overturn the predictions for the structure of trade by the factor-abundance (HO) model. Trade patterns, as predicted by this model, can both be magnified or reversed by uneven concentration of production factors within a country. Cities are...

Distance related variables typically vary in a cross-section dimension but less so in a time dimension across cities, regions, or countries. The enlargement of the EU or the introduction of the euro, however, can be looked upon as integration shocks that are informative of the consequences of...

The literature on China indicates that the concentration of economic activities in China is less than in other industrialized countries. Institutional limits are largely held responsible for this finding (e.g. the Hukou system); firms and workers are not able to take full advantage of the...

This paper shows that subsidy competition may be efficiency enhancing. We model a subsidy game among two asymmetric regions in a new trade model, where capital can freely move among regions, but capital rewards are repatriated. We study subsidy competition, starting from an equilibrium where the...

Using a rich data set on the EU regions, we analyze the relevance of two possible determinants of a region’s resilience to shocks, the degree of urbanization and specialization. We take the Great Recession, the economic and financial crisis that started in 2008, as our shock and then analyze...

We study the optimal and equilibrium size of cities in a city system model with environmental pollution. Pollution is related to city size through the effect of population on production, commuting, and housing consumption. With symmetric cities, if pollution is local or per capita pollution...

We provide empirical evidence of the dynamics of city size distribution for the whole of the twentieth century in U.S. cities and metropolitan areas. We focus our analysis on the new cities that were created during the period of analysis. The main contribution of this paper, therefore, is the...
