摘要

面对仿制药的竞争，品牌药公司有时会通过第三方实体推出自己的仿制药，称为“授权仿制药”(AGs)。如果这一策略奏效，那么每一种专利到期的品牌药物都应该成立一个AG。然而，这与只有一小部分品牌药物含有AGs的事实相矛盾。为了解释这个谜题，我开发了一个两期模型，在这个模型中，一家知名制药公司在仿制药进入市场之前利用自己的品牌。该模型预测，只有当品牌忠诚度足够弱时，品牌公司才会推出AG。

Brand Loyalty and Generic Entry: Why do Brand-Name Drug Companies Launch Their Own Generics?

Facing generic competition, brand-name drug companies sometimes launch their own generics called “authorised generics” (AGs) through a third-party entity. If that strategy works, an AG should be launched for every branded drug that comes off patent. This, however, contradicts the fact that only a small proportion of branded drugs have had AGs. To explain this puzzle, I develop a two-period model in which a brand-name drug company exploits its name brand before generic entry. The model predicts that the brand-name company launches an AG only when brand loyalty is sufficiently weak.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
