This study uses a unique firm-level dataset to examine how falling trade costs from 1993-2001 affected entry, exit, productivity, and exporting in the Korean manufacturing sector. We verify many of the predictions of recent heterogeneous-firm models of international trade. For example, falling...

We utilize a global trade model to generate distributions of commodity and factor prices based on observed uncertainty in rice production. This is done for three trade policy regimes. We then assess their impact on domestic price variability and the likelihood of marginal households falling into...

The making of projections often requires an economy-wide perspective, and the estimation of consumer demands at the international level. In this paper, an implicit, directly additive demand system (AIDADS) is estimated using cross-country data on consumer expenditures from the International...

Elevated prices for major U.S. commodities have renewed interest in the price sensitivity of foreign demand facing the United States. Although the elasticity of foreign demand plays an important role in discussions of U.S. farm policy, it is also a parameter that is much debated with the...

We examine how changes in yield variability affect the welfare of cereal grain and oilseed buyers and producers around the world. We simulate trade patterns and welfare for 21 countries with a Ricardian trade model that incorporates bilateral trade costs and crop yield distributions. The model...

New information communication technology is a good opportunity to exchange information and to get feedback from customers shortening the traditional channel of social relationships. In different countries over the time there has been a significant growth of social interactions by social networks...
