The Evolution of Physician Practice Styles: Evidence from Cardiologist Migration

Abstract: Physician treatment choices for observably similar patients vary dramatically across regions. This paper exploits cardiologist migration to disentangle the role of physician-specific factors such as preferences and learned behavior versus environment-level factors such as hospital capacity and productivity spillovers on physician behavior. Physicians starting in the same region and subsequently moving to dissimilar regions practice similarly before the move. After the move, physician behavior in the first year… Show more

“…hospitals), facing different external (market) environments or working with different colleagues (peer effects). Molitor (2018) studies the effect of the hospital environment in determining the considerable regional variation in invasive procedures for patients who have had a heart attack. He exploits cardiologist migration between (large) regions in the US to examine if cardiologists change their style in a new clinical setting.…”

“…Most closely related are Song et al (2010), who look at how health measures change around patient moves, and Molitor (2014), who looks at cardiologist behavior changes around their moves. Outside of the health care sector, a number of papers beginning with Abowd et al (1999) use matched worker-firm data to separately identify worker and firm fixed effects.…”

“…Our paper also contributes to a small but growing literature on the impact of providers on the healthcare sector. Much of this literature has focused on the effect of financial incentives on provider behavior (e.g., Cutler, 1995;Clemens and Gottlieb, 2014;Ho and Pakes, 2014;Eliason et al, 2018;Einav, Finkelstein and Mahoney, 2018), or more broadly on the role of the physician in affecting healthcare decisions (e.g., Barnett, Olenski and Jena, 2017;Molitor, 2018). Our study is unusual in that it studies the impact of a specific institution (or organizational form) on the efficiency of the healthcare sector.…”
