July 2019Does the Healthcare Educational Market Respond to Short-Run Local Demand?
with Marcus Dillender, Cong T. Gian, Kosali I. Simon: w26088
The Patient Protection and Affordable Care Act (ACA) increased demand for healthcare across the U.S., but it is unclear if or how the supply side has responded to meet this demand. In this paper, we take advantage of plausibly exogenous geographical heterogeneity in the ACA to examine the healthcare education sector’s response to increased demand for healthcare services. We look across educational fields, types of degrees, and types of institutions, paying particular attention to settings where our conceptual model predicts heightened responses. We find no statistically significant evidence of increases in graduates and can rule out fairly modest effects. This implies that healthcare production may have adjusted to increased demand from insurance expansion in other ways rather than prima...

April 2018Ambulance Utilization in New York City after the Implementation of the Affordable Care Act
with Charles Courtemanche, Daniel I. Rees: w24480
Expanding insurance coverage could, by insulating patients from having to pay full cost, encourage the utilization of arguably unnecessary medical services. It could also eliminate (or at least diminish) the need for emergency services through increasing access to preventive care. Using publicly available data from New York City for the period 2013-2016, we explore the effect of the Affordable Care Act (ACA) on the volume and composition of ambulance dispatches. Consistent with the argument that expanding insurance coverage encourages the utilization of unnecessary medical services, we find that, as compared to dispatches for more severe injuries, dispatches for minor injuries rose sharply after the implementation of the ACA. By contrast, dispatches for pre-labor pregnancy complication...
August 2017The Affordable Care Act and Ambulance Response Times
with Charles Courtemanche, Andrew P. Koller, Daniel I. Rees: w23722
This study contributes to the literature on supply-side adjustments to insurance expansions by examining the effect of the Affordable Care Act (ACA) on ambulance response times. Exploiting temporal and geographic variation in the implementation of the ACA as well as pre-treatment differences in uninsured rates, we estimate that the expansions of private and Medicaid coverage under the ACA combined to slow ambulance response times by an average of 19%. We conclude that, through extending coverage to individuals who, in its absence, would not have availed themselves of emergency medical services, the ACA added strain to emergency response systems.
