November 2016Intertemporal Substitution in Health Care Demand: Evidence from the RAND Health Insurance Experiment
with Daniel W. Sacks: w22802
Nonlinear cost-sharing in health insurance encourages intertemporal substitution be- cause patients can reduce their out-of-pocket costs by concentrating spending in years when they hit the deductible. We test for such intertemporal substitution using data from the RAND Health Insurance Experiment, where people were randomly assigned either to a free care plan or to a cost-sharing plan which had coinsurance up to a maximum dollar expenditure (MDE). Hitting the MDE—leading to an effective price of zero—has a bigger effect on monthly health care spending and utilization than does being in free care, because people who hit the MDE face high future and past prices. As a result, we estimate that sensitivity to short-lasting price changes is about twice as large as sensitivity to long-lasting ch...
July 2015Information Technology and Patient Health: Analyzing Outcomes, Populations, and Mechanisms
with Seth Freedman, Jeffrey Prince: w21389
We study the effect of hospital adoption of electronic medical records (EMRs) on health outcomes, particularly patient safety indicators (PSIs). We find evidence of a positive impact of EMRs on PSIs via decision support rather than care coordination. Consistent with this mechanism, we find an EMR with decision support is more effective at reducing PSIs for less complicated cases, using several different metrics for complication. These findings indicate the negligible impacts for EMRs found by previous studies focusing on the Medicare population and/or mortality do not apply in all settings.
May 2014Public Health Insurance Expansions and Hospital Technology Adoption
with Seth Freedman, Kosali Simon: w20159
This paper explores the effects of public health insurance expansions on hospitals' decisions to adopt medical technology. Specifically, we test whether the expansion of Medicaid eligibility for pregnant women during the 1980s and 1990s affects hospitals' decisions to adopt neonatal intensive care units (NICUs). While the Medicaid expansion provided new insurance to a substantial number of pregnant women, prior literature also finds that some newly insured women would otherwise have been covered by more generously reimbursed private sources. This leads to a theoretically ambiguous net effect of Medicaid expansion on a hospital's incentive to invest in technology. Using American Hospital Association data, we find that on average, Medicaid expansion has no statistically significant effect on...
