Are Important Innovations Rewarded? Evidence from Pharmaceutical Markets

No 12420, CEPR Discussion Papers from C.E.P.R. Discussion Papers
This paper focuses on the relationship between therapeutic value and different measures of market rewards (the number of patents, price, market share, and total revenues) of a new treatment. Using an assessment of therapeutic value provided by the French Haute Authoritï¿½ de Santï¿½ (HAS), I find a weak relationship between most measures of rewards and this assessment of therapeutic value, suggesting that the returns to developing a "me-too" product are not very different from developing treatments with greater therapeutic effects. One interpretation is that the HAS score is a poor assessment of therapeutic value, in which case the use of similar health technology assessments by governments and other payers should be re-examined. Alternatively, if the HAS score is informative, the results suggest countries are spending too much on less innovative products, and that a re-balancing of innovation incentives may be worth considering if therapeutic value is highly related to social welfare.
