|January 2016||Healing the Poor: The Influence of Patient Socioeconomic Status on Physician Supply Responses|
with Darius N. Lakdawalla: w21930
A longstanding literature explores how altruism affects the way physicians respond to incentives and provide care. We analyze how patient socioeconomic status mediates these responses. We show theoretically that patient socioeconomic status systematically influences the way physicians respond to reimbursement changes, and we identify the channels through which these effects operate. We use two Medicare reimbursement changes to investigate these insights empirically. We confirm that a given physician facing an increase in reimbursement boosts utilization by more when treating richer patients. We show that average supply price elasticities vary from 0.02 to 0.18 for a given physician, depending on the patient’s socioeconomic status. Finally, we show that the Medicare reforms we study led to ...

|August 2015||Health Care Spending: Historical Trends and New Directions|
with Dana Goldman: w21501
Over the last five decades, broad changes in the US health care system have dramatically influenced growth in health care expenditures. These structural changes have also influenced the trajectory of the health economics research. This paper reviews some of the seminal health economics papers (measured by citations) and identifies the salient factors driving the growth of medical expenditures. We find that the research identified – and was strongly influenced by – four eras of expenditure growth: (1) coverage expansion; (2) experimentation with financial incentives; (3) the managed care backlash; and (4) a golden era of declining expenditure growth. We conclude by discussing some themes from this research suggesting optimism that, going forward, we can curb excess expenditure growth above ...

|September 2014||Why is Infant Mortality Higher in the US than in Europe?|
with Emily Oster, Heidi Williams: w20525
The US has higher infant mortality than peer countries. In this paper, we combine micro-data from the US with similar data from four European countries to investigate this US infant mortality disadvantage. The US disadvantage persists after adjusting for potential differential reporting of births near the threshold of viability. While the importance of birth weight varies across comparison countries, relative to all comparison countries the US has similar neonatal (<1 month) mortality but higher postneonatal (1-12 months) mortality. We document similar patterns across Census divisions within the US. The postneonatal mortality disadvantage is driven by poor birth outcomes among lower socioeconomic status individuals.
