Efforts to strengthen the global patent system for pharmaceuticals continue to be controversial, and what will likely be a similarly fraught international debate over price controls has begun. The outcome of international negotiations and the resulting policy decisions made by each country will...

Economic literature has extensively studied how prices for incumbent pharmaceutical drugs respond to generic competition after entry. However, less attention has been paid to pricing behavior in anticipation of brand-to-brand competition. We contribute to this gap in the literature by both...

Importation of drugs into the U.S. would result in a decline in U.S. drug prices. The purpose of this paper is to assess the consequences of importation for new drug development. A simple theoretical model of drug development suggests that the elasticity of innovation with respect to the...

The recent withdrawal of Cox-2 Inhibitors has generated debate on the role of information in drug diffusion: can the market learn the efficacy of new drugs, or does it depend solely on manufacturer advertising and FDA updates? In this study, we use a novel data set to study the diffusion of...

This study examines the effect of chain store entry on drug quality and prices in the retail pharmacy market in Hyderabad, India. In contrast to prevailing mom-and-pop pharmacies, chains exploit scale economies to offer high-quality drugs at lower cost. With a unique data set and a natural...

Experts claim that some Indian drug manufacturers cut corners and make substandard drugs for markets with non-existent, under-developed or emerging regulatory oversight, notably Africa. This paper assesses the quality of 1470 antibiotic and tuberculosis drug samples that claim to be made in...

This paper studies how insurance coverage policies impact pharmaceutical innovation. In the United States, most patients obtain prescription drugs through insurance plans administered by Pharmacy Benefit Managers (PBMs). Beginning in 2012, PBMs began excluding coverage for many newly approved...

Empirical studies suggest that entry of generic competitors results in minimal decreases or even increases in brand-name drug prices as well as sharp declines in brand-name advertising. This paper examines circumstances under which this empirical pattern could be observed. The analysis focuses...

We examine the role of network effects in the demand for pharmaceuticals at both the brand level and for a therapeutic class of drugs. These effects emerge when use of a drug by others conveys information about its efficacy and safety to patients and physicians. This can lead to herd behavior...

We examine the role of consumption externalities in the demand for pharmaceuticals at both the brand level and over a therapeutic class of drugs. These effects emerge when use of a drug by others affects its value, and/or conveys information abut efficacy and safety to patients and physicians....
