We construct a tractable general equilibrium model of cumulative innovation and growth, in which new ideas strictly improve upon frontier technologies, and productivity improvements are drawn in a stochastic manner. The presence of positive knowledge spillovers implies that the decentralized...

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...

On May 30, 2017, the Supreme Court held that the initial authorized sale of a patented item within or outside the U.S. “exhausts” all rights of the patentee to that item under the Patent Act. This decision goes against the Government's position that a foreign sale authorized by the U.S....

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...
