In my testimony to the Senate Judiciary Committee, I explained the benefits of legislation addressing anticompetitive conduct that brand-name drug companies have employed: sample denials, pay-for-delay settlements, citizen petitions, product hopping, and patent thickets. By increasing generic...

This document (of 401 pages) comprises the proceedings of an OECD roundtable on competition and regulation issues in the pharmaceutical industry. The pharmaceutical sector is a dynamic, research-intensive industry that is fundamentally influenced by a web of regulations designed to (a) promote...

In the pharmaceuticals sector there is an inherent tension between intellectual property rights and antitrust. This paper examines this tension over the past 10 years since modernisation of EU competition law. It looks at three types of problems: (i) restrictions on parallel imports; (ii) abuse...

We present a Hotelling model of price and advertising competition between prescription drugs that differ in quality/side effects. Promotional effort results in the endogenous formation of two consumer groups: brand loyal and non-brand loyal ones. We show that advertising intensities are...

Policy makers use reference pricing to curb pharmaceutical expenditures by reducing coverage of expensive branded drugs. In a theoretical analysis we show that the net effect of reference pricing is generally ambiguous when accounting for entry by generic producers. Reference pricing shifts...

We study the effect of the degree of exclusivity for the lowest bidder on the average price of generic pharmaceuticals in the short and long terms. Our results indicate that a 1-percentage-point gain in market share of the lowest bidder reduces average costs by 0.2% in the short term and 0.8% in...

I study the incentives of oligopolists to acquire and disclose information on a common demand intercept. Since firms may fail to acquire information even when they invest in information acquisition, firms can credibly conceal unfavorable news while disclosing favorable news. Firms may earn...

This paper empirically assesses the impact of the intensity of competition on investment in new technologies within the mobile telecommunications industry. Using firm level panel data and an instrumental variable estimation it finds an inverted-U relationship between competition intensity and...

This paper considers a general symmetric quantity-setting oligopoly where the "coefficient of cooperation" defined by Cyert and DeGroot (An Analysis of Cooperation and Learning in a Duopoly Context, 1973) is interpreted as the parameter indicating severity of competition. It is obtained that...

We develop a structural econometric framework that allows us to simulate the effects of mergers among two-sided platforms selling differentiated products. We apply the proposed methodology to the Dutch newspaper industry. Our structural model encompasses demands for differentiated products on...
