Patent term restoration for top-selling drugs in the USA.

Patents temporarily protect brand-name drugs from generic competition, but some of the 20-year patent term is used up before marketing approval. To compensate for patent life lost to clinical testing and regulatory review, current law provides patent term restoration (PTR) of up to 5 years. Examining 170 top-selling drugs approved between 2000 and 2012, we found that 49% (83 drugs) received a PTR extension (median extension: 2.75 years) yielding a median total exclusivity period of 13.75 years, compared wit...

How Endogenous Crowd Formation Undermines the Wisdom of the Crowd in Online Ratings.

People frequently consult average ratings on online recommendation platforms before making consumption decisions. Research on the wisdom-of-the-crowd phenomenon suggests that average ratings provide unbiased quality estimates. Yet we argue that the process by which average ratings are updated creates a systematic bias. In analyses of more than 80 million online ratings, we found that items with high average ratings tend to attract more additional ratings than items with low average ratings. We call this asy...
