The relationship between geography and trade is a central topic in international economics. This paper investigates the potential existence of a continental bias in world trade flows on a sample of 182 countries over the period 1990-2006. Using traditional estimation techniques and recent...

We develop a framework for studying how differences in the level and/or dispersion of per-capita income affect trade structure and welfare in a two-country model. Thereby, we embed nonhomothetic preferences into a home-market model with two sectors of production and one input factor. We...

This paper illustrates the effect of employment in the tradable sector on employment in the non-tradable sector in the same city with a simple model. The model predicts a significant positive local employment multiplier that increases in size with the unemployment rate. It also predicts that the...

This paper claims that distance alone is a poor proxy for international transport costs in gravity equations. We develop a theoretical framework with a manufacturing and a transport sector, where the level of manufacturing exports determines the demand for transport. Above a certain threshold,...

This paper posits a new approach to the 'wage equation' of the New Economic Geography (NEG). On one side, it is shown that the NEG provides a spatial explanation of marginal costs, instead of wages. On the other side, and focusing on the statistical properties of the data, it is explained why...
