The Impact of Consolidation on Prescription Drug Pricing and Access

This study will investigate the impact of mergers between drug manufacturers and between pharmacy benefits managers (PBMs) on prices of drugs and on patient access to drugs as dictated by formularies. The model of drug price negotiation between manufacturers and PBMs that will be developed in this study will support assessment of the potential pricing and access effects of future mergers and other policy changes, and can help regulators to improve antitrust screening.
