We report a puzzling pair of facts concerning the organization of science. The concentration of research output is declining at the department level but increasing at the individual level. For example, in evolutionary biology, over the period 1980 to 2000, the fraction of citation-weighted...

Scientific freedom and openness are hallmarks of academia: relative to their counterparts in industry, academics maintain discretion over their research agenda and allow others to build on their discoveries. This paper examines the relationship between openness and freedom, building on recent...

In many growth models, economic growth arises from people creating ideas, and the long-run growth rate is the product of two terms: the effective number of researchers and their research productivity. We present a wide range of evidence from various industries, products, and firms showing that...

Are scientific knowledge flows embodied in individuals, or "in the air"? To answer this question, we measure the effect of labor mobility in a sample of 9,483 elite academic life scientists on the citation trajectories associated with individual articles (resp. patents) published (resp. granted)...

The growing peer effects literature pays particular attention to the role of stars. We decompose the causal effect of hiring a star in terms of the productivity impact on: 1) co-located incumbents and 2) new recruits. Using longitudinal university department-level data we report that hiring a...

This paper studies how corporate research and development (R&D) investment affects labor mobility. We use employer-employee matched data in ordinary least squares and instrumental variables analyses to assess four hypotheses. R&D has no effect on worker retention, exit from employment, or...

There is growing public interest in alternatives to intellectual property including, but not limited to, prizes and government grants. We argue that there is no single best mechanism for supporting research. Rather, mechanisms can only be compared within specific creative environments. We...

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,...

Despite growing empirical evidence of the link between environmental policy and innovation, most economic models of … innovation in the energy sector. Ignoring induced technological change overstates the welfare costs of an optimal carbon tax …, as the effect of induced innovation on emissions and mean global temperature is small. Sensitivity analysis shows that …
