Do hospitals respond to decreasing prices by supplying more services?

Area of Science:

• Health Economics
• Hospital Management
• Healthcare Policy

Background:

• Regulated prices are a prevalent feature in healthcare markets, significantly influencing provider behavior.
• Understanding the impact of price regulations on healthcare service volume is crucial for effective policy-making.
• Previous research has not fully elucidated the nuanced relationship between reimbursement price changes and hospital service supply.

Purpose of the Study:

• To estimate the effect of changes in regulated reimbursement prices on the volume of hospital care.
• To analyze the impact of a specific hospital financing reform in Germany on hospital service supply.
• To investigate the income effect of prices on the volume of medical care.

Main Methods:

• Utilized administrative data from a German hospital financing reform that altered overall reimbursement levels.
• Analyzed the relationship between price changes (increases for some hospitals, decreases for others) and hospital service volume.
• Examined potential nonlinearities in the volume response to price changes.

Main Results:

• Hospitals reduced service supply in response to increasing reimbursement prices.
• Hospitals increased service supply in response to decreasing reimbursement prices.
• Evidence suggests a nonlinear relationship between price changes and volume adjustments.

Conclusions:

• The findings indicate that hospitals react counterintuitively to price changes, reducing volume when prices rise and increasing it when prices fall.
• This behavior is interpreted as evidence of a negative income effect, where higher prices lead to reduced service provision.
• The study highlights the complex interplay between price regulation and hospital service volume, with implications for healthcare financing reforms.
