We develop a simple model of international outsourcing and apply it to processing trade in China. Export processing involves a foreign firm contracting with a Chinese factory manager to assemble intermediate inputs into a final product. Whether the same or different parties should have ownership...

We estimate the relative influence of trade versus technology on wages in a "large-country" setting, where technological change affects product prices. Trade is measured by the foreign outsourcing of intermediate inputs, while technological change is measured by expenditures on high-technology...

We develop a simple model of international trade with heterogeneous firms that is consistent with a number of stylized features of the data. In particular, the model predicts positive as well as zero trade flows across pairs of countries, and it allows the number of exporting firms to vary...

Stabilization programs in open economies typically consist of two stages. In the first stage, the rate of currency devaluation is reduced, but the fiscal adjustment do es not eliminate the fiscal deficit that causes growth of debt and lo ss of reserves, making a future policy change necessary....

We develop a two-country model of endogenous innovation and imitation in order to study the interactions between these two processes. Firms in the North race to bring out the next generation of a set of technology-intensive products. Each product potentially can be improved a countably infinite...

We develop a novel model of campaigns, elections, and policy-making in which the ex ante objectives of national party leaders differ from the ex post objectives of elected legislators. This generates a distinction between "policy rhetoric" and "policy reality" and introduces an important role...

We develop an equilibrium model of industrial structure in which the organization of firms is endogenous. Differentiated consumer products can be produced either by vertically integrated firms or by pairs of specialized companies. Production of each variety of consumer good requires a...
