The general consensus among health economists is that the increasing capability of medical providers-often called medical "technology"-is responsible for the majority of growth in medical expenditure. And yet, the principle means of understanding medical technology is through the use of total...

We study the choice of drug for the treatment of high blood pressure (hypertension) in Sweden between 1988-1994. During this time period calcium antagonists and ACE-inhibitors increased their market shares at the expense of the older drugs diuretics and beta-blockers. We use a prescription micro...

We empirically examine the determinants of adoption of information technology by primary healthcare clinics using a large sample of physician clinics from several States in the U.S. Ours is one of the first studies to intensively investigate primary care clinics. These clinics are important as...

Using data on all bariatric surgeries performed in the state of Pennsylvania from 1995 through 2007, this paper uses logistic and OLS regressions to measure the effect of star physicians and star hospitals on the diffusion of an innovation in bariatric surgery called laparoscopic gastric bypass...

This paper explores the adoption choice of electronic medical records by U.S hospitals, which could exhibit strategic complements or substitutes. I find complementarities in adoption through a reduced-form analysis with instruments for the unobserved market characteristics. I further develop a...

This paper seeks to understand the incentives of affiliated hospitals in choosing health information technology (IT) vendors. By adopting a system popular in the local market, hospitals may benefit from complementarities but also worry about losing patients. If benefits outweigh the competitive...

Covid-19 has sparked substantial growth in direct-to-consumer telemedicine (DCT) provision, intensifying healthcare competition by expanding patient choice sets. I analyze the causal effect of new DCT entrants on incumbent healthcare providers, leveraging quasi-experimental variation in market...

We examine whether user-generated physician ratings from online sources signal physician quality information and affect patients' physician choices. We collect physician rating and review data from Yelp, a leading online physician rating platform, and match the rating data with Medicare claims...

We show that review platforms reduce healthcare interruptions for patients looking for a new physician. We employ a difference-in-differences strategy using physician retirements as a “disruptive shock” that forces patients to find a new physician. We combine insurance claims data with...

In 2019 and the early months of 2020, global trade faced two major albeit very different shocks, namely the United States-China trade war and the cascading response of the countries around the world to the COVID-19 pandemic. While the former situation involved a pair of centrally-placed trading...
