Reference pricing and firms' pricing strategies.

Area of Science:

• Behavioral Economics
• Industrial Organization
• Health Economics

Background:

• Reference pricing is a common healthcare reimbursement strategy.
• Understanding its impact on firm pricing and market outcomes is crucial.
• Existing models often simplify firm interactions and product differentiation.

Purpose of the Study:

• To analyze the effects of different reference pricing reimbursement rules on firms' pricing strategies.
• To investigate the time consistency of reference pricing policies.
• To compare market outcomes under distinct reference price formulations.

Main Methods:

• Economic modeling using a horizontal differentiation framework.
• Inclusion of heterogeneous product qualities.
• Analysis of two reference price rules: minimum observed price and a linear combination of prices.

Main Results:

• The 'minimum policy' prevents firms from coordinating on higher prices.
• The 'linear policy' acts as an implicit price coordination device.
• Compared to the 'linear policy', the 'minimum policy' leads to higher total/private expenditures and lower consumer surplus/firm profits.
• Quality differentiation amplifies price increases under both policies.

Conclusions:

• Reference pricing policies significantly influence firms' pricing behavior and market dynamics.
• The specific rule of reference price determination critically affects economic outcomes.
• Policy design must consider the coordination effects and potential for unintended consequences on expenditures and welfare.
