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....

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...

There is wide dispersion in pharmaceutical prices across countries with comparable quality standards. Under monopoly, off-patent and generic drug prices are at least four times higher in the United States than in comparable English-speaking high income countries. With five or more competitors,...

Despite their importance to the supply of prescription drugs, there has been limited research on pharmacy benefit managers (PBMs) and their vertical relationships to insurers and drug manufacturers. This paper provides an overview of the current state of research on this topic, motivates why...

We establish four facts concerning competition among U.S. generic drug suppliers, using IQVIA's National Sales Perspective™ 2004Q4 - 2016Q3 data. We define a unique product market ("molform"), consisting of the combination of a molecule active ingredient and a route of administration...

We provide causal evidence that regulatory shocks associated with drug safety label changes lead to aggregate demand declines of 16.9 percent within two years of a relabeling event. After accounting for all plausible substitution patterns by physicians along with competitor actions, aggregate...

In this survey chapter on pricing and reimbursement in U.S. pharmaceutical markets, we first provide background information on important federal legislation, institutional details regarding distribution channel logistics, definitions of alternative price measures, related historical...

EU countries closely regulate pharmaceutical prices whereas the U.S. does not. This paper shows how price constraints affect the profitability, stock returns, and R&D spending of EU and U.S. firms. Compared to EU firms, U.S. firms are more profitable, earn higher stock returns, and spend more on...

With substantial fixed costs of drug development, more common conditions can support more products. If additional pharmaceutical products are beneficial, they will attract greater consumption and promote better health, e.g. greater longevity. We ask how market size measured by condition...

There is a long-standing literature that recognizes that an efficient solution in correcting a consumption externality is through applying subsidies and taxes that line up private incentives with social ones. An equally long-standing literature tackles the appropriate methods of generating the...
