Competition and the value of innovation
Abstract
We examine how competition affects the economic returns firms derive from their patented innovations. Using a stock market-based measure that reflects the discounted cash flows of newly granted patents, we document a robust negative relationship between competition intensity and the economic value of patents. To establish causality, we implement a quasi-experimental design and consider horizontal M&A as events that are likely to reduce competition for non-merging industry peers. Leveraging the random timing of peers’ patent grant dates within a narrow window around M&A announcements, we show that patents granted immediately after such events on average experience a 2.8% increase in value. This effect is stronger for deals that are more likely to be anti-competitive, but is absent for non-horizontal mergers that are unlikely to alter competition intensity. Overall, we offer new insights into the competition-innovation relationship by showing that competition weakens the economic returns that incentivize firm innovation.
