September 2018Creativity Under Fire: The Effects of Competition on Creative Production
w25057
Though fundamental to innovation and essential to many industries and occupations, individual creativity has received limited attention as an economic behavior and has historically proven difficult to study. This paper studies the incentive effects of competition on individuals' creative production. Using a sample of commercial logo design competitions, and a novel, content-based measure of originality, I find that intensifying competition induces agents to produce original, untested ideas over tweaking their earlier work, but heavy competition drives them to stop investing altogether. The results yield lessons for the management of creative workers and for the implementation of competitive procurement mechanisms for innovation.
December 2017Scale versus Scope in the Diffusion of New Technology: Evidence from the Farm Tractor
w24125
Using the farm tractor as a case study, I show that lags in technology diffusion arise along two distinct margins, which I term scale and scope. Though tractors are now used in nearly every agricultural field operation and in the production of nearly all crops, they first developed with much more limited application. Early diffusion was accordingly rapid in these narrower applications, but limited in scope until tractor technology generalized. The sequence of diffusion is consistent with a model of R&D in specific- versus general-purpose attributes and with other historical examples, suggesting that the key to understanding technology diffusion lies not only in explaining the number of different users, but also in explaining the number of different uses.
