Our analysis is motivated by the observation that the strengthening of patent protection and the increase in R&D in the US coincide with a reduction in growth volatility beginning in the mid 1980s. To analyze this phenomenon, we develop an R&D-based growth model with aggregate uncertainty in the innovation process and apply the model to ask whether increasing patent strength and R&D can lead to a significant reduction in growth volatility. We find a small but non-negligible effect that explains no less than 10% of the observed reduction in growth volatility in the US.enPeer Reviewed Journal Article10.1016/j.jmacro.2012.04.002
