Collaboration, Stars, and the Changing Organization of Science : Evidence from Evolutionary Biology

Agrawal, Ajay K. - 2014

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...

An Exploration of Local R&D Spillovers in France

Mairesse, Jacques - 2010

This paper is an attempt to assess the existence and magnitude of local research spillovers in France. We rely on the model of an extended production function (Cobb-Douglas and Translog) with both local and neighborhood Ramp;D capital stocks. We estimate this model on 312 employment areas as of...

Does Scientist Immigration Harm Us Science? An Examination of Spillovers

Agrawal, Ajay K. - 2018

The recruitment of foreign scientists enhances US science through an expanded workforce but could also cause harm by displacing better connected domestic scientists, thereby reducing localized knowledge spillovers. We develop a model in which a sufficient condition for the absence of overall...

Identifying Age, Cohort and Period Effects in Scientific Research Productivity : Discussion and Illustration Using Simulated and Actual Data on French Physicists

Hall, Bronwyn H.; Mairesse, Jacques; Turner, Laure - 2021

The identification of age, cohort (vintage), and period (year) effects in a panel of individuals or other units is an old problem in the social sciences, but one that has not been much studied in the context of measuring researcher productivity. In the context of a semi-parametric model of...

Birds of a Feather - Better Together? Exploring the Optimal Spatial Distribution of Ethnic Inventors

Agrawal, Ajay K. - 2013

We examine how the spatial and social proximity of inventors affects knowledge flows, focusing especially on how the two forms of proximity interact. We develop a knowledge flow production function (KFPF) as a flexible tool for modeling access to knowledge and show that the optimal spatial...
