  • Inertia, Market Power, and Adverse Selection in Health Insurance

    Evan Saltzman, Ashley Swanson et al.ARTICLEThe Review of Economics and…2025

    We study how inertia interacts with market power and adverse selection in health insurance. We incorporate inertia into a model of plan selection and price competition, and estimate it using data from the California ACA exchange. We estimate inertia costs equaling 26% of average premiums. Our simulations indicate that inertia exacerbates market power, but has minimal interaction with selection. Eliminating inertia reduces average premiums by 6.6%…

  • Medicare-Covered Services Near the End of Life in Medicare Advantage vs Traditional Medicare

    Open AccessLauren Hersch Nicholas, Stacy M Fischer et al.ARTICLEJAMA Health Forum2024

  • Macular Degeneration Drug Prescribing Patterns After Step Therapy Introduction in Medicare Advantage

    Open AccessAngela Liu, Kelly E Anderson et al.ARTICLEJAMA Health Forum2024

    The findings of this retrospective encounter-based analysis indicate that step therapy is associated with a greater probability of prescribing the plan-preferred drug for the first administration. The analysis failed to find a statistically significant greater rate of medication switching within a treatment episode. Step therapy changed macular degeneration prescribing patterns, but step therapy alone did not transition all administrations to the…

  • Role of Patient Sorting in Avoidable Hospital Stays in Medicare Advantage vs Traditional Medicare

    Open AccessJianhui Xu, Kelly E Anderson et al.ARTICLEJAMA Health Forum2023

    In this cross-sectional study of MA and TM beneficiaries, the lower rate of avoidable hospital stays among MA beneficiaries than TM beneficiaries was attributable to MA beneficiaries visiting clinicians with lower rates of avoidable hospital stays. The patient sorting that occurs in MA plays a critical role in the lower rates of avoidable hospital stays compared with TM

    Open AccessNiya Khanjar, Jonathan Hall et al.ARTICLEEnvironmental Justice2021

    Mississippi's growing poultry business, including industrialized farms and meatpacking plants, raises a number of concerns regarding public health and environmental justice.

  • Acuity-based Scheduling in Primary Care

    Molly Candon, Karin Rhodes et al.ARTICLEMedical Care2018Referências: 13

    OBJECTIVES: Triage algorithms are ubiquitous in emergency care settings, but the extent of their use in primary care is unknown. This study asks whether primary care practices prioritize patients with more acute service needs. METHODS: We used an audit study in which simulated patients were randomized to 2 clinical scenarios-a new patient seeking a routine check-up or a new patient seeking treatment for newly diagnosed hypertension-and attempted …

  • Primary Care Appointment Availability for Medicaid Patients

    Simon Basseyn, Brendan Saloner et al.ARTICLEMedical Care2016Referências: 12

    BACKGROUND: Arkansas and Iowa received waivers from the federal government in 2014 to use federal Medicaid expansion funding to enroll beneficiaries in commercial insurance plans on the Marketplaces.

  • Real-World Data

    Anirban Basu, Kirsten Axelsen et al.ARTICLEMedical Care2016Referências: 12

    As real-world data (RWD) in health care begin to cross over to the Big Data realms, a panel of health economists was gathered to establish how well the current US policy environment further the goals of RWD and, if not, what can be done to improve matters. This report summarizes these discussions spanning the current US landscape of RWD availability and usefulness, private versus public development of RWD assets, the current inherent bias in term…

  • High deductible health plans

    Open AccessNeal Gupta, Daniel PolskyARTICLEHealth Expectations2015

    OBJECTIVE: To determine whether increased cost sharing in health insurance plans induces higher levels of consumer sophistication in a non-elderly population. STUDY DESIGN: This analysis is based on the collection of survey and demographic data collected from enrollees in the RAND health insurance experiment (HIE). During the RAND HIE, enrollees were randomly assigned to different levels of cost sharing (0, 25, 50 and 95%). METHODS: The study pop…

    Using longitudinal data on practicing obstetricians from 1998 to 2004 derived from Pennsylvania, Florida, and New York hospital discharge data, this study finds that rising malpractice premiums are associated with an increased rate of exit and a reduced rate of entry for obstetricians. In Pennsylvania and Florida, where premiums rose by an average of 20% per year for four years, the combined effect of more exits and fewer entries was associated w…
