    Karen Shen, Eric Barrette, and Leemore S. Dafny

    Journal of Industrial Economics: Any Willing Provider and Negotiated Retail Pharmaceutical Prices
    Daniel Hosken, David Schmidt, Matthew C Weinberg
    April 29, 2020

    Abstract:  Any Willing Provider (AWP) regulations require insurers to allow health care providers network membership, eliminating an insurer’s ability to commit to a limited network of providers. We study the effect of AWP on prices negotiated between insurers and providers by exploiting the introduction of a regulation targeting retail pharmacies in the state of Maine. Using…

    Health Affairs: Prevalence And Characteristics Of Surprise Out-Of-Network Bills From Professionals In Ambulatory Surgery Centers
    Erin L. Duffy, Loren Adler, Paul B. Ginsburg, and Erin Trish
    April 15, 2020

    Abstract:  Patients treated at in-network facilities can involuntarily receive services from out-of-network providers, which may result in “surprise bills.” While several studies report the surprise billing prevalence in emergency department and inpatient settings, none document the prevalence in ambulatory surgery centers (ASCs). The extent to which health plans pay a portion or all of out-of-network…

    February 4, 2019

    Abstract: Evidence suggests that growth in providers’ prices drives growth in health care spending on the privately insured. However, existing work has not systematically differentiated between the growth rate of hospital prices and that of physician prices. We analyzed growth in both types of prices for inpatient and hospital-based outpatient services using actual negotiated prices…
