Competition versus regulation: some empirical evidence.

J Merrill, C McLaughlin

    Journal of Health Politics, Policy and Law
    |January 1, 1986
    PubMed
    Summary

    Health maintenance organizations (HMOs) and regulatory strategies did not significantly reduce overall hospital costs. Supply factors, like hospital beds and specialists, were the primary drivers of cost and utilization increases.

    Area of Science:

    • Health economics
    • Healthcare policy
    • Health services research

    Background:

    • Rising healthcare costs prompt debate on regulatory vs. competitive strategies.
    • Health maintenance organizations (HMOs) are promoted as a competitive strategy to control costs.
    • Increased HMO enrollment is hypothesized to drive down overall hospital expenditures through market competition.

    Purpose of the Study:

    • To examine the impact of HMO growth and regulatory activity on healthcare costs and utilization.
    • To determine if competition or regulation effectively contains hospital expenditures.
    • To identify the primary drivers of healthcare costs and utilization.

    Main Methods:

    • Analysis of data from the 25 largest Metropolitan Statistical Areas (MSAs) between 1971 and 1981.
    • Statistical control for environmental conditions within each market.
    • Examination of the relationship between HMO market share, regulatory activity, and hospital cost/utilization metrics.

    Main Results:

    • Neither increased HMO enrollment nor regulatory activity demonstrated a significant impact on reducing overall hospital costs.
    • No generalizable effect of competition or regulation on hospital costs was observed across markets.
    • Increases in healthcare costs and utilization were primarily driven by supply-side factors, including hospital bed capacity and the number of medical specialists.

    Conclusions:

    • Market-based competition through HMOs and regulatory interventions were not effective in controlling overall hospital costs during the study period.
    • Healthcare cost containment strategies need to consider supply-side dynamics.
    • Further research may be needed to explore localized effects or alternative cost-control mechanisms.
