February 2016The Mobility of Elite Life Scientists: Professional and Personal Determinants
with Pierre Azoulay, Joshua S. Graff Zivin: w21995
As scientists’ careers unfold, mobility can allow researchers to find environments where they are more productive and more effectively contribute to the generation of new knowledge. In this paper, we examine the determinants of mobility of elite academics within the life sciences, including individual productivity measures and for the first time, measures of the peer environment and family factors. Using a unique data set compiled from the career histories of 10,004 elite life scientists in the U.S., we paint a nuanced picture of mobility. Prolific scientists are more likely to move, but this impulse is constrained by recent NIH funding. The quality of peer environments both near and far is an additional factor that influences mobility decisions. Interestingly, we also identify a significa...

May 2015It's Good to be First: Order Bias in Reading and Citing NBER Working Papers
with Daniel R. Feenberg, Patrick Gaule, Jonathan Gruber: w21141
Choices are frequently made from lists where there is by necessity some ordering of options. In such situations individuals can exhibit both primacy bias towards the first option and recency bias towards the last option. We examine this phenomenon in a particularly interesting context: consumer response to the ordering of economics papers in an email announcement issued by the National Bureau of Economic Research (NBER). Each Monday morning Eastern Standard Time (EST) the NBER issues a “New This Week” (NTW) email that lists all of the working papers that have been issued in the past week. This email goes to more than 23,000 subscribers, both inside and outside academia, and the placement order is based on random factors. We show that despite the randomized list placement, papers that ...

January 2014Why and Wherefore of Increased Scientific Collaboration
with Richard B. Freeman, Raviv Murciano-Goroff: w19819
This paper examines international and domestic collaborations using data from an original survey of corresponding authors and Web of Science data of articles that had at least one US coauthor in the fields of Particle and Field Physics, Nanoscience and Nanotechnology, and Biotechnology and Applied Microbiology. The data allow us to investigate the connections among coauthors and the views of corresponding authors about the collaboration. We have four main findings. First, we find that US collaborations have increased across US cities as well as across international borders, with the nature of collaborations across cities resembling that across countries. Second, face-to-face meetings are important in collaborations: most collaborators first met working in the same institution and communi...
