What has been the overall global welfare impact of the accession to the World Trade Organization of a large country like China, or the global welfare impact of the completion of the Uruguay round of GATT negotiations? Can we come up with a simple user-friendly formula to calculate the global...

To study the effects of tariffs on gross domestic product (GDP), one needs import demand elasticities at the tariff line level that are consistent with GDP maximization. These do not exist. Kee, Nicita, and Olarreaga modify Kohli's (1991) GDP function approach to estimate demand elasticities for...

This paper examines the relationship between the credit constraints faced by a firm and the unit value prices of its exports. The paper modifies Arkolakisś (2010) model of trade with heterogeneous firms by introducing endogenous quality and credit constraints. The model predicts that tighter...

The doctrine of patent exhaustion implies that the authorized sale of patented goods “exhausts” the patent rights in the goods sold and precludes additional license fees from downstream buyers. Courts have considered absolute exhaustion, in which the patent owner forfeits all rights upon an...

The doctrine of "patent exhaustion" implies that the authorized sale of patented goods "exhausts" the patent rights in the goods sold and precludes additional license fees from downstream buyers. This paper offers the first formal economic model of domestic patent exhaustion that incorporates...

We study the incentives that governments have to protect intellectual property in a trading world economy. We consider a world economy with ongoing innovation in two countries that differ in market size and in their capacities for innovation. We associate the strength of IPR protection with the...

This paper analyzes the setting of national patent policies in the global economy. In the standard model with free trade and social-welfare-maximizing governments à la Grossman and Lai (2004), cross-border positive policy externalities induce individual countries to select patent strengths that...
