This article seeks to explain the contradiction between the promises of welfare gains derived from the economic models recommending the removal of immigration restrictions and the realities experienced by countries attempting to apply restrictions to immigration flows. A formal model is built in...

Motivated by increasing trade and fragmentation of production across countries since World War II, we build a dynamic two-country model featuring sequential, multi-stage production and capital accumulation. As trade costs decline over time, global-value-chain (GVC) trade expands across...

The trade literature often treats countries as dimensionless points, which is a strong assumption. Agglomeration or lumpiness of production factors within countries can affect the national pattern of trade. In this paper we analyze comparative advantage patterns for 22 cities and 4 regions for...

This paper constructs a theoretical model to illustrate the inherent dynamics between the trade imbalance and the comparative advantage of factor endowment structure under a two-country setting (South vs North). Our model shows that the shift of comparative advantage of factor endowment...

There are various ways to indicate the importance of international trade. In this paper, we use the "labor footprint" concept to gain new insights into the implications of trade for employment. We focus on the US, but also provide information on 39 other, mostly developed, countries for the...

In this chapter we discuss the role of natural resources and endowment structures on structural change. Departing from theories of trade that stress specialization according to one's comparative advantages as the key route to development, we articulate an alternative point of view on the role of...
