Eastern enlargement of the EU promises gains, but also imposes fiscal costs on incumbent countries. A sensitive issue concerns immigration, jobs and wages. We address these issues in a general equilibrium framework, both analytically and through numerical simulations. Analytical results identify...

Economic globalization causes an increasing international fragmentation of value-added chains. A question often raised is whether such outsourcing affects domestic income distribution. The paper provides a theoretical treatment of this issue within a Heckscher-Ohlin framework. It extends beyond...

In this paper, we explore the role of trade in differentiated final goods as well offshoring of tasks for inequality both within and between countries. We emphasize the distinction between managerial and production labor. Production labor is assumed to be a variable input composed of tradable...

We decompose the native welfare effect of immigration into...
