Budish, Eric B. - 2016
A well-developed theoretical literature — dating back at least to Nordhaus (1969) — has analyzed optimal patent policy design. We re-present the core trade-off of the Nordhaus model and highlight an empirical question which emerges from the Nordhaus framework as a key input into optimal...

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...
