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...

We examine the issue of new goods and price indexes for the important and tractable case of generic and branded drugs. By treating generics as entirely distinct goods and "linking them in" to indexes with fixed weights, the standard price indexes fail to reflect the substantial welfare gains to...

I use variation in approval time for generic drugs to shed light on the objectives of the federal agency in charge of granting entry permission for these drugs (FDA). Applications belonging to firms later found to have engaged in fraud or corruption were approved nine months faster on average,...

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

During the 1980s the share of prescriptions sold by retail pharmacies that was accounted for by generic products roughly doubled. The price response to generic entry of brand-name products has been a source of controversy. In this paper we estimate models of price responses to generic entry in...

This paper analyzes determinants of ex-manufacturer prices for originator and generic drugs across a large sample of countries. We focus on drugs to treat HIV/AIDS, TB and malaria in middle and low income countries (MLICs), with robustness checks to other therapeutic categories and other...
