May 2014The Effect of Child Health Insurance Access on Schooling: Evidence from Public Insurance Expansions
with Sarah Cohodes, Daniel Grossman, Michael F. Lovenheim: w20178
Public health insurance programs comprise a large share of federal and state government expenditures. Although a sizable literature analyzes the effects of these programs on health care utilization and health outcomes, little prior work has examined the long-term effects and resultant health improvements on important outcomes, such as educational attainment. We contribute to filling this gap in the literature by examining the effects of the public insurance expansions among children in the 1980s and 1990s on their future educational attainment. Our findings indicate that expanding health insurance coverage for low-income children increases the rate of high school completion and college completion. These estimates are robust to only using federal Medicaid expansions, and mostly are due to e...

March 2012Do High-Cost Hospitals Deliver Better Care? Evidence from Ambulance Referral Patterns
with Joseph J. Doyle, Jr., John A. Graves, Jonathan Gruber: w17936
Endogenous patient sorting across hospitals can confound performance comparisons. This paper provides a new lens to compare hospital performance for emergency patients: plausibly exogenous variation in ambulance-company assignment. Ambulances are effectively randomly assigned to patients in the same area based on rotational dispatch mechanisms. Using Medicare data from 2002-2008, we show that ambulance company assignment importantly affects hospital choice for patients in the same zip code. Using data for New York state from 2000-2006 that matches exact patient addresses to hospital discharge records, we show that patients who live very near each other but on either side of ambulance-dispatch boundaries go to different types of hospitals. Both strategies show that higher-cost hospitals hav...

January 2011A Structural Approach to Market Definition With an Application to the Hospital Industry
with Martin Gaynor, William B. Vogt: w16656
Market definition is essential to merger analysis. Because no standard approach to market definition exists, opposing parties in antitrust cases often disagree about the extent of the market. These differences have been particularly relevant in the hospital industry, where the courts have denied seven of eight merger challenges since 1994, due largely to disagreements over geographic market definition. We compare geographic markets produced using common ad hoc methodologies to a method that directly applies the "SSNIP test" to hospitals in California using a structural model. Our results suggest that previously employed methods overstate hospital demand elasticities by a factor of 2.4 to 3.4 and define larger markets than would be implied by the merger guidelines's hypothetical monopolist ...

March 2010Do Strikes Kill? Evidence from New York State
with Jonathan Gruber: w15855
Concerns over the impacts of hospital strikes on patient welfare led to substantial delay in the ability of hospitals to unionize. Once allowed, hospitals unionized rapidly and now represent one of the largest union sectors of the U.S. economy. Were the original fears of harmful hospital strikes realized as a result? In this paper we analyze the effects of nurses' strikes in hospitals on patient outcomes. We utilize a unique dataset collected on nurses' strikes over the 1984 to 2004 period in New York State, and match these strikes to a restricted use hospital discharge database which provides information on treatment intensity, patient mortality and hospital readmission. Controlling for hospital specific heterogeneity, patient demographics and disease severity, the results show that nurse...
