Using detailed data on biotechnology in Japan, we find that identifiable collaborations" between particular university star scientists and firms have a large positive impact on firms'" research productivity, increasing the average firm's biotech patents by 34 percent development by 27 percent,...

We examine the effects of university-based star scientists on three measures of performance for California biotechnology enterprises: the number of products in development, the number of products on the market, and changes in employment. The `star' concept which Zucker, Darby, and Brewer (1994)...
