We study innovation incentives in the presence of "product hopping," whereby the incumbent patents a minor modification of a drug (e.g., a new delivery method) and invests in marketing to switch demand towards the minor modification. In our setting firms compete sequentially to discover two...

In a patent infringement suit, the alleged infringer wins with a ruling of either patent invalidity or non-infringement. It is ambiguous which of these outcomes is preferred by the alleged infringer. Invalidity may increase current-period competition, but simultaneously removes constraints to...

Hearing on "Net Neutrality: Is Antitrust Law More Effective than Regulation in Protecting Consumers and Innovation?" Testimony of Bruce M. Owen before the Subcommittee on Regulatory Reform, Commercial and Antitrust Law, Committee on the Judiciary, U.S. House of Representatives, Washington DC,...

The conventional antitrust wisdom is that the formation of patent pools is welfare en- hancing when patents are complementary, since the pool avoids a double-marginalization problem associated with independent licensing. The focus of this paper is on (down- stream) product development and...

The conventional wisdom is that the formation of patent pools is welfare enhancing when patents are complementary, since the pool avoids a double-marginalization problem associated with independent licensing. This conventional wisdom relies on the effects that pooling has on downstream prices....

Basic innovations are often fundamental to the development of applications that maybe developed by other innovators. In this setting, we investigate whether patent pools canrectify the lack of incentives for developers to invest in applications. Following Green andScotchmer (1995), we also...

Research and Development (R&D) and innovation are crucial features of the seed industry. To supportlarge R&D investments by the private sector, strong intellectual property rights, such as patents, arenecessary. The exclusivity granted by patents naturally creates market power positions and...

Many high technology goods are based on standards that require several essential patents owned by different IP holders. This gives rise to a complements and a double mark-up problem. We compare the welfare effects of two different business strategies dealing with these problems. Vertical...

The conventional wisdom is that the formation of patent pools is welfare enhancing when patents are complementary, since the pool avoids a double-marginalization problem associated with independent licensing. This conventional wisdom relies on the effects that pooling has on downstream prices....

This papers analyses how horizontal mergers affect innovation activities of the merged entity and its non-merging competitors. We develop an oligopoly model with heterogeneous firms to derive empirically testable implications. Our model predicts that a merger is more likely to be profitable in...
