演講摘要 : The speed of diffusion of post-patent pharmaceuticals has important implications both on the reduction of pharmaceutical expenditures and on the incentive to innovate. Exploiting rich micro-panel data, I study the diffusion of post-patent pharmaceuticals. I find that doctors on average fail to internalize patient costs and strong state dependence exists in prescription choices. These explain why cheaper generics diffuse slowly. Consequently, returns from innovations may be higher in pharmaceuticals. Results also indicate that financial incentives are a key driver for the diffusion of generics. However, financial incentives can also be costly, and I offer some cautionary remarks.
