We explore the role of trade in differentiated final goods as well ollshoring of tasks for inequality both within and between countries. We emphasize the distinction between managerial and production labor. Managerial labor is a fixed input while production labor is a variable input. Following...

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...
