Estimates of mortality models imply that actual life expectancy of HIV/AIDS patients in 2001 was 13.4 years higher than it would have been if the drug utilization rate had not increased from its 1993 level. Estimates of a model of hospital discharges imply that increased utilization of HIV drugs...

A patent only protects an innovator from others producing the same product, but it does not protect him from others producing better products under new patents. Therefore, one may divide up the source of competition facing an innovator into within-patent competition, which results from...

Between 1960 and 1997, life expectancy at birth of Americans increased approximately 10% - from 69.7 to 76.5 years - and it has been estimated that the value of life extension during this period nearly equaled the gains in tangible consumption. We investigate whether an aggregate health...

Prior literature has established a link between changes in market size and pharmaceutical innovation; whether a link exists with scientific research remains an open question. If upstream research is not responsive to these changes, the kinds of scientific discoveries that flow into future drug...

In this paper we document significantly steeper declines in nondurable expenditures in the UK compared to the US, in spite of income paths being similar. We explore several possible causes, including different employment paths, housing ownership and expenses, levels and paths of health status,...

We study the effect of the COVID-19 pandemic on chronic disease drug adherence. Focusing on asthma, we use a database that tracks the vast majority of prescription drug claims in the U.S. from 2018 to 2020. Using a difference-in-differences empirical specification, we compare monthly drug...

Does using prescription drugs off-label increase disability and medical expenditure? This paper uses a unique dataset to evaluate off-label vs. on-label drug use in the US non-institutionalized population. Patients using drugs off-label have on average $515 higher medical expenditure and...
