We develop a model to explain two-way migration of high-skilled individuals between countries that are similar in their economic characteristics. High-skilled migration is explained by a combination of two features: In both countries there is a continuum of workers with differing abilities,...

We set up a two-country general equilibrium model, in which heterogeneous firms from one country (the source country) can offshore routine tasks to a low-wage host country. The most productive firms self-select into offshoring, and the impact on welfare in the source country can be positive or...

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...

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 study how two distinct forms of globalisation, trade cost reductions and opening up of trade in previously shielded sectors, affect sector-specific wages, employment levels and aggregate welfare in a two-country model of general oligopolistic equilibrium (GOLE) with partly unionised labour...

We develop a general equilibrium two-country model with heterogeneous producers and rent sharing at the firm level due to fairness preferences of workers. We identify two sources of a multinational wage premium. On the one hand, there is a pure composition effect because multinational firms are...

This paper formulates a structural empirical model of heterogeneous firms whose workers exhibit fair-wage preferences. In the underlying theoretical framework, such preferences lead to a link between a firm's operating profits on the one hand and wages of workers employed by this firm on the...

This paper derives a new effect of trade liberalisation on the quality of the environment. We show that in the presence of heterogeneous firms the aggregate volume of emissions is influenced not only by the long-established scale effect, but also by a reallocation effect resulting from an...
