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...
