|March 2020||Out of the Woodwork: Enrollment Spillovers in the Oregon Health Insurance Experiment|
with Katherine Baicker, Amy Finkelstein: w26871
We analyze the impact of expanded adult Medicaid eligibility on the Medicaid enrollment of already-eligible children. To do so, we exploit the 2008 Oregon Medicaid lottery, in which some low-income uninsured adults were randomly selected for the chance to apply for Medicaid. Children in these households were eligible for Medicaid irrespective of whether the household won the lottery. We estimate statistically significant but transitory impacts of adult lottery selection on children’s Medicaid enrollment: for every 9 adults who enroll in Medicaid due to the lottery, one additional child also enrolls at the same time. Our results shed light on the existence, magnitude, and nature of so-called “woodwork effects”.
|April 2018||Adoption and Learning Across Hospitals: The Case of a Revenue-Generating Practice|
Performance-raising practices tend to diffuse slowly in the health care sector. To understand how incentives drive adoption, I study a practice that generates revenue for hospitals: submitting detailed documentation about patients. After a 2008 reform, hospitals could raise their Medicare revenue over 2% by always specifying a patient’s type of heart failure. Hospitals only captured around half of this revenue, indicating that large frictions impeded takeup. Exploiting the fact that many doctors practice at multiple hospitals, I find that four-fifths of the dispersion in adoption reflects differences in the ability of hospitals to extract documentation from physicians. Hospital adoption is robustly correlated with generating survival for heart attack patients and using inexpensive survival...

|October 2015||Healthcare Exceptionalism? Performance and Allocation in the U.S. Healthcare Sector|
with Amitabh Chandra, Amy Finkelstein, Chad Syverson: w21603
The conventional wisdom in health economics is that idiosyncratic features of the healthcare sector leave little scope for market forces to allocate consumers to higher performance producers. However, we find robust evidence across a variety of conditions and performance measures that higher quality hospitals tend to have higher market shares at a point in time and expand more over time. Moreover, we find that the relationship between performance and allocation is stronger among patients who have greater scope for hospital choice, suggesting a role for patient demand in allocation in the hospital sector. Our findings suggest that the healthcare sector may have more in common with “traditional” sectors subject to standard market forces than is often assumed.

|July 2013||Healthcare Exceptionalism? Productivity and Allocation in the U.S. Healthcare Sector|
with Amitabh Chandra, Amy Finkelstein, Chad Syverson: w19200
The conventional wisdom in health economics is that large differences in average productivity across hospitals are the result of idiosyncratic, institutional features of the healthcare sector which dull the role of market forces. Strikingly, however, we find that productivity dispersion in heart attack treatment across hospitals is, if anything, smaller than in narrowly defined manufacturing industries such as ready-mixed concrete. While this fact admits multiple interpretations, we also find evidence against the conventional wisdom that the healthcare sector does not operate like an industry subject to standard market forces. In particular, we find that hospitals that are more productive at treating heart attacks have higher market shares at a point in time and are more likely to expand ...
