Demand-driven Technical Change and Productivity Growth: Theory and Evidence from the Energy Policy Act

Impullitti, Giammario; Kneller, Richard; McGowan, Danny

Abstract

We present novel evidence on the effect of market size on technology adoption and productivity. Our tests exploit a natural experiment in the US corn industry where changes to national energy policy created exogenous increases in demand. Difference-in-difference estimates show that the demand shock caused technical change as corn producers adopted higher quality seeds which in turn raised productivity by 7%. We develop a simple model that formalizes the mechanisms underlying our results.
