This paper analyzes trade in an asymmetric 2×2×2 world, where the two countries, labelled America and Europe, differ in their attitudes towards wage inequality. In both America and Europe, fair wage considerations compress differentials between the wages for skilled and unskilled workers,...

The policy debate views offshoring as job destruction. Theoretical models of offshoring mostly assume full employment. We develop a model of task trade that allows for equilibrium unemployment. In this model, there are two margins of adjustment. At the extensive margin, moving tasks offshore...

Over the last 20 years the border-effect literature repeatedly documented the trade-reducing effect of inter- and intra-national borders. Thereby, the sheer size and persistence of observed border effects from the beginning raised doubts on the genuine effect of underlying borders. However, when...

We offer a theoretical explanation and empirical evidence for a positive link between increased offshoring and individual skill upgrading. Skill upgrading takes the form of on-the-job training, complementing the existing literature, which mainly focuses on the retraining of workers after a...

We revisit Grossman and Rossi-Hansberg's (2008) famous result, that under certain conditions offshoring of low-skilled labor tasks raises the domestic wage for low-skilled workers. Our re-examination features a less benign environment where Rybczynski-type reallocation of factors to absorb...

We present supportive empirical evidence and a new theoretical explanation for the negative selection into planned return migration between similar regions in Germany. In our model costly temporary and permanent migration are used as imperfect signals to indicate workers' high but otherwise...

This paper identifies a “border” effect in the absence of a border. The finding that trade between East- and West-Japan is 23.1 to 51.3 percent lower than trade within both country parts, is established despite the absence of an obvious east-west division due to historical borders, cultural...

We propose and apply a new theory-consistent algorithm, which uses disaggregated inter-city trade data to identify a pyramidic city system with central places and associated hinterlands. Because central places possess more industries than the cities in their hinterlands, and because industries,...
