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

Agrawal, Ajay - 2013

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...

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

Agrawal, Ajay - 2007

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...

University Patenting : Estimating the Diminishing Breadth of Knowledge Diffusion and Consumption

Rosell, Carlos - 2006

The rate of university patenting increased dramatically during the 1980s. To what extent did the knowledge flow patterns associated with public sector inventions change as university administrators and faculty seemingly became more commercially oriented? Using a Herfindahl-type measure of patent...

Does Scientist Immigration Harm US Science? An Examination of Spillovers

Agrawal, Ajay - 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...

Characterizing the Drug Development Pipeline for Precision Medicines

Chandra, Amitabh - 2017

Precision medicines - therapies that rely on the use of genetic, epigenetic, and protein biomarkers - create a better match between patients with specific disease subtypes and medications that are more effective for those patients. This heterogeneity in response has implications for the decision...

Does Knowledge Accumulation Increase the Returns to Collaboration?

Agrawal, Ajay - 2013

We conduct the first empirical test of the knowledge burden hypothesis, one of several theories advanced to explain increasing team sizes in science. For identification, we exploit the collapse of the USSR as an exogenous shock to the knowledge frontier causing a sudden release of previously...

The Economics of Medical Procedure Innovation

Dranove, David; Garthwaite, Craig; Heard, R. Christopher; … - National Bureau of Economic Research - 2021

This paper explores the economic incentives for medical procedure innovation. Using a proprietary dataset on billing … code applications for emerging medical procedures, we highlight two mechanisms that could hinder innovation. First, the … administrative hurdle of securing permanent, reimbursable billing codes substantially delays innovation diffusion. We find that …
