Ever since the seminal RAND Health insurance experiment (HIE) was conducted, most health care services, including pharmaceuticals, are deemed to be price inelastic with price elasticities of demand (PED) close to -0.20. However, most studies of PED exploit natural experiments that change demand...

This paper uses Roy's model of sorting behavior to study welfare implication of current health care data production infrastructure that relies on solicitation of research subjects. We show that due to severe adverse-selection issues, directionality of bias cannot be established and welfare may...

This paper builds on the methods of local instrumental variables developed by Heckman and Vytlacil (1999, 2001, 2005) to estimate person-centered treatment (PeT) effects that are conditioned on the person's observed characteristics and averaged over the potential conditional distribution of...

Advocates of traditional antitrust are increasingly called upon to the defend the existing framework. In doing so they face a challenge: the traditional framework is actually quite difficult to explain. The problem is not that modern antitrust involves a lot of advanced economics — though that...

Monopolization, in the United States, and abuse of dominance, in the European Union, embody different philosophies about how best to police single firm conduct in competition law. Surprisingly, their disagreement ends at market definition. Both doctrines define relevant markets by similar...

Background: The WHO recommends use of masks and social distancing to reduce transmission and death from COVID-19. Governments worldwide also rely on test-trace-isolate (TTI) programs for additional risk mitigation. This study aims to estimate the cost-effectiveness of implementing a national TTI...
