|February 2018||Hospital Pricing and Public Payments|
with Michael Darden, Eric Barrette: w24304
A longstanding debate in health economics and health policy concerns how hospitals adjust prices with private insurers following reductions in public funding. A common argument is that hospitals engage in some degree of "cost-shifting," wherein hospitals increase prices with private insurers in response to a reduction in public payments; however, evidence of significant cost-shifting is mixed, and the rationale for such behavior is unclear. We enter this debate by examining plausibly exogenous variation in Medicare payment rates generated by two policies under the Affordable Care Act: the Hospital Readmission Reduction Program (HRRP) and the Hospital Value Based Purchasing (HVBP) program. We merge rich hospital-level information to actual private-payer payment data from a large, multi-pa...
|July 2017||It's a Cruel Summer: Household Responses to Reductions in Government Nutrition Assistance|
with Lorenzo Almada: w23633
The appropriate size and scope of government nutrition assistance programs is a regular source of debate among policy-makers, and with calls to reduce government benefits, a clear understanding of household responses to any proposed benefit reduction is critical. Exploiting the design of U.S. nutrition assistance programs, we examine how low-income households reallocate their budgets following an exogenous reduction in nutrition assistance benefits. The magnitude of our results suggests that the budget for an average low-income household with children is severely inflexible and likely unable to absorb more than a $2 to $3 reduction in nutrition benefits per child per week.

|September 2015||What Can We Learn About the Effects of Food Stamps on Obesity in the Presence of Misreporting?|
with Lorenzo Almada, Rusty Tchernis: w21596
There is an increasing perception among policy makers that food stamp benefits contribute positively to adult obesity rates. We show that these results are heavily dependent on one's assumptions regarding the accuracy of reported food stamp participation. When allowing for misreporting, we find no evidence that SNAP participation significantly increases the probability of being obese or overweight among adults. Our results also highlight the inherent bias and inconsistency of common point estimates when ignoring misreporting, with treatment effects from instrumental variable methods exceeding the non-parametric upper bounds by over 200% in some cases.
