Abstract: Using a narrative identification of US tax changes over the post-WWII period, we show that corporate income tax cuts foster R&D spending and innovation, leading to a persistent increase in aggregate productivity and output. In contrast, changes in the average personal income tax rate have mostly short-term effects. An estimated endogenous productivity model highlights the role of “applied research†- over and above formal R&D - as a main force behind these results, and suggests a social rate of return to investment in innovation between 20% and 75%.
