We investigate behavioral responses to a staggered disruption in the supply of prescription opioids across U.S. states: the introduction of electronic Prescription Drug Monitoring Programs (PDMPs). Using administrative datasets, we find PDMPs curtail the proliferation of prescription opioids....

What makes prescription drugs cost so much? The media and Congress say it is corporate greed, while pharmaceutical firms blame federal regulations and an expensive drug development process. This study focuses on R & D (R&D) expenditures at global pharmaceutical firms and explores the driving...

We introduce a simple oligopolistic trade model with international transportation costs, and analyze the profitability and the social desirability of national vs. international mergers in relation to three different issues, (i) the level of trade freeness, (ii) the possibility of rent...

Imperfect competition in labor markets can lead to efficiency losses and lower aggregate output. In this paper, we study whether differences in competitiveness of labor markets can help explain differences in GDP per capita across countries. We structurally estimate a model of oligopsony with...

We consider a model where firms first decide whether to invest in general human capital, then make wage offers for each others' trained employees and finally engage in imperfect product market...

This paper develops a new method for estimating production-function parameters that can be applied in differentiated-product industries with endogenous quality and variety choice. We take advantage of data on physical quantities of outputs and inputs from the Colombian manufacturing survey,...
