This paper provides evidence on the monopolistic competition model with heterogeneous firms and endogenous productivity. We show that this model has a well-defined GDP function where relative export variety enters positively, and estimate this function over 48 countries from 1980 to 2000....

The elasticity of substitution between goods from different countries—the Armington elasticity—is important for many questions in international economics, but its magnitude is subject to debate: the "macro" elasticity between home and import goods is often found to be smaller than the...

This paper develops a procedure to rank-order countries and commodities using disaggregated US imports data. It finds strong evidence that both countries and commodities can be ranked, consistent with the ‘product cycle’ hypothesis. Countries habitually begin to export goods to the United...

This paper offers an explanation for the persistence observed in real exchange rate movements. The model combines pricing to market behavior with sticky prices generated by staggered contracts. A translog preference structure is used to enhance both features. The paper finds that openness limits...

We study outsourcing from the United States under the offshore assembly program (OAP). Formerly called the 806/807 provision of the U.S. tariff code, and now renamed the 9802 provision of the Harmonized System code, this program allows U.S. firms to export component parts and have them assembled...

The last few decades have seen a spectacular integration of the global economy through trade. The rising integration of world markets has brought with it a disintegration of the production process, however, as manufacturing or services activities done abroad are combined with those performed at...

The goal of this paper is to theoretically and empirically demonstrate the consequences of different imputation methods, using recent data from the International Price Program. We suppose that prices are missing due to random or erratic reporting. We consider three different imputation methods:...
