We test how market overvaluation affects corporate innovation. Estimated stock overvaluation is very strongly associated with measures of innovative inventiveness (novelty, originality, and scope), as well as R&D and innovative output (patent and citation counts). Misvaluation affects R&D more via a non-equity channel than via equity issuance. The sensitivity of innovative inventiveness to misvaluation is increasing with share turnover and overvaluation. The frequency of exceptionally high innovative inputs/outputs increases with overvaluation. This evidence suggests that market overvaluation may generate social value by increasing innovative output and by encouraging firms to engage in highly inventive innovation.
