Abstract

Recent evidence suggests that Medicare Part D has increased prescription drug use among the elderly, and earlier studies have indicated that increasing market size induces pharmaceutical innovation. This paper assesses the impact of Medicare Part D on pharmaceutical research and development (R&D), using time-series data on (a) the number of drugs in clinical development by therapeutic class, and (b) R&D expenditures by firm. We demonstrate that the passage of Medicare Part D was associated with significantly higher pharmaceutical R&D for drug classes with higher Medicare market share, and for firms specializing in higher-Medicare-share drugs.
