April 2018How the Reformulation of OxyContin Ignited the Heroin Epidemic
with William N. Evans, Patrick Power: w24475
We attribute the recent quadrupling of heroin death rates to the August, 2010 reformulation of an oft-abused prescription opioid, OxyContin. The new abuse-deterrent formulation led many consumers to substitute to an inexpensive alternative, heroin. Using structural break techniques and variation in substitution risk, we find that opioid consumption stops rising in August, 2010, heroin deaths begin climbing the following month, and growth in heroin deaths was greater in areas with greater pre-reformulation access to heroin and opioids. The reformulation did not generate a reduction in combined heroin and opioid mortality—each prevented opioid death was replaced with a heroin death.
January 2018Targeting with In-kind Transfers: Evidence from Medicaid Home Care
with Lee M. Lockwood: w24267
Many of the most important government programs make transfers in kind as opposed to in cash. Making transfers in kind has the obvious cost that recipients would often prefer cost-equivalent cash transfers. But making transfers in kind can have benefits as well, including better targeting transfers to desired recipients or states of the world. In this paper, we develop a framework for evaluating this tradeoff and apply it to home care. Exploiting large-scale randomized experiments run by three state Medicaid programs, we find that in-kind provision of formal home care significantly reduces the value of benefits to recipients while targeting benefits to a small fraction of the eligible population that has greater demand for formal home care, is sicker, and has worse informal care options tha...
April 2017Cost of Service Regulation in U.S. Health Care: Minimum Medical Loss Ratios
with Steve Cicala, Victoria Marone: w23353
A health insurer's Medical Loss Ratio (MLR) is the share of premiums spent on medical claims. The Affordable Care Act introduced minimum MLR provisions for all health insurance sold in fully-insured commercial markets, thereby capping insurer profit margins, but not levels. While intended to reduce premiums, we show this rule creates incentives analogous to cost of service regulation. Using variation created by the rule's introduction as a natural experiment, we find claims costs rose nearly one-for-one with distance below the regulatory threshold: 7% in the individual market, and 2% in the group market. Premiums were unaffected.
