Is there a competitive market for hospital services?
Insights
Hospitals possess significant market power, particularly for patients with Blue Cross insurance or those paying out-of-pocket. This pricing power allows them to set higher prices, impacting healthcare costs.
Area of Science:
- Health Economics
- Hospital Market Analysis
- Healthcare Pricing Strategies
Background:
- Hospitals often operate with varying pricing strategies for different patient groups.
- Understanding price elasticity of demand is crucial for analyzing hospital market power.
Purpose of the Study:
- To estimate the price elasticity of hospital-specific demand curves.
- To assess hospital market power across different payer types (Medicare, Medicaid, Blue Cross, commercial insurance, HMOs, self-pay).
Main Methods:
- Developed a pricing rule to infer hospital-specific price elasticities.
- Analyzed payer admission distributions to identify price-sensitive patient segments.
- Utilized data from 31 Minneapolis-St. Paul hospitals in 1981.
Main Results:
- Hospitals demonstrated monopoly power in markets for Blue Cross and self-pay/commercial insurance/HMO patients.
- This market power was confirmed and extended to Medicare patients through demand analysis.
Conclusions:
- Hospitals leverage significant pricing power, especially with non-governmental payers.
- Findings highlight the complex interplay between hospital pricing, payer mix, and market competition.
Abstract:
This paper focuses on the price elasticity of hospital-specific demand curves. Each hospital is assumed to practice price discrimination with respect to Medicare, Medicaid, and other patients. Among the third group, patients covered by Blue Cross are analyzed separately from those who pay their own bills or are covered by commercial insurance or a health maintenance organization (HMO). We use two different methods to estimate the price elasticity of demand. First, a pricing rule is developed from which hospital-specific price elasticities may be inferred. Second, the distribution of each payer's admissions at specific hospitals is examined to determine if low-priced hospitals attract more patients. Data for the analysis are taken from 31 hospitals in the Minneapolis-St. Paul metropolitan area in 1981. Results of the first analytic method indicate that hospitals had monopoly power in their markets for Blue Cross and self pay/commercial insurance/HMO patients. These results are confirmed and extended to Medicare patients by the hospital demand analysis.
