|August 2017||Politics, Hospital Behavior, and Health Care Spending|
with Amanda E Kowalski, Eleanor N Powell, Jennifer Wu: w23748
This paper examines the link between legislative politics, hospital behavior, and health care spending. When trying to pass sweeping legislation, congressional leaders can attract votes by adding targeted provisions that steer money toward the districts of reluctant legislators. This targeted spending provides tangible local benefits that legislators can highlight when fundraising or running for reelection. We study a provision - Section 508 – that was added to the 2003 Medicare Modernization Act (MMA). Section 508 created a pathway for hospitals to apply to get their Medicare payment rates increased. We find that hospitals represented by members of the House of Representatives who voted ‘Yea’ on the MMA were significantly more likely to receive a 508 waiver than hospitals represented by m...
|July 2017||Surprise! Out-of-Network Billing for Emergency Care in the United States|
with Fiona Scott Morton, Nathan Shekita: w23623
Using insurance claims data, we show that in 22% of emergency episodes, patients attended in-network hospitals, but were treated by out-of-network physicians. Out-of-network billing allows physicians to significantly increase their payment rates relative to what they would be paid for treating in-network patients. Because patients cannot avoid out-of-network physicians during an emergency, physicians have an incentive to remain out-of-network and receive higher payment rates. Hospitals incur costs when out-of-network billing occurs within their facilities. We illustrate in a model and confirm empirically via analysis of two leading physician-outsourcing firms that physicians offer transfers to hospitals to offset the costs of out-of-network billing and allow the practice to continue. We fi...
|December 2015||The Price Ain’t Right? Hospital Prices and Health Spending on the Privately Insured|
with Stuart V. Craig, Martin Gaynor, John Van Reenen: w21815
We use insurance claims data for 27.6 percent of individuals with private employer-sponsored insurance in the US between 2007 and 2011 to examine the variation in health spending and in hospitals’ transaction prices. We document the variation in hospital prices within and across geographic areas, examine how hospital prices influence the variation in health spending on the privately insured, and analyze the factors associated with hospital price variation. Four key findings emerge. First, health care spending per privately insured beneficiary varies by a factor of three across the 306 Hospital Referral Regions (HRRs) in the US. Moreover, the correlation between total spending per privately insured beneficiary and total spending per Medicare beneficiary across HRRs is only 0.14. Second, var...
