This paper analyzes the relationship between firms’ innovation success and their capital structures. I hypothesize that firms’ innovation success reduces the extent of information asymmetry facing them in the equity market, leading to a greater propensity of firms to issue equity rather than debt to raise external financing. Supporting these hypotheses, I show empirically that firms with higher levels of innovation success have lower leverage ratios and a greater propensity to issue equity rather than debt. Further, these firms face a lower extent of information asymmetry in the equity market. I establish causality using instrumental variable analyses, instrumenting for patent grants with patent examiner leniency.

We analyze how corporate direct investments in fintech startups affect startup performance and that of investing firms. Corporate investment in fintech startups is associated with a greater likelihood of successful exit, more and higher-quality innovation, and a greater inflow of high-quality inventors. A stacked difference-in-differences analysis shows that direct investments enhance the operating performance and equity-market valuation of corporate investors in the financial services sector, but not those in the nonfinancial sector. We establish two channels that drive fintech startups’ performance improvements: strategic alliance formation between investors and startups, and enhanced startup monitoring by corporate investors.
