Do financial derivatives enhance or impede innovation? We answer this question by examining the relationship between equity options markets and standard measures of firm innovation. We find that firms with more options trading activity generate more patents and patent citations per dollar invested in research and development (R&D), after accounting for other confounding factors. These results are confirmed when we use a propensity score matching procedure and an instrumental variable approach to control for the potential endogeneity of options trading. The evidence is consistent with the notion that the enhanced informational efficiency induced by options leads to an improved allocation of corporate resources. We further discuss possible underlying economic mechanisms through which more active options markets boost innovation and show that the effect remains substantial even after controlling for these mechanisms. Considering the average increase in the dollar volume of options traded for our sample firms, we conclude that a 200% move in options volume increases firm innovation by about 31%.

Equity option markets can have a dual effect on firms' cost of debt. On the one hand, options attract more informed investors, which increases price informativeness and reduces information asymmetries in the market, facilitating firm financing. On the other, by attracting more informed investors who provide reassurance regarding managerial career concerns, options can increase the potential for risk shifting in firms. We explore these two channels via different tests on corporate bond yields and use different econometric specifications including quasi-natural experiments to mitigate endogeneity concerns. We find evidence consistent with the preeminence of the risk-shifting channel when private managerial risk-taking incentives are sufficiently high and debtholders are more exposed to expropriation.

ABSTRACT We examine how the prospect of research and development (R&D) disclosure affects a firm’s institutional investor base. Difference-in-differences (DiD) regressions around the enactment of the American Inventors Protection Act (AIPA), which mandated the public disclosure of patent applications within 18 months of filing, show that short-term institutional investors increase their holdings before public information is released, whereas long-term investors do not adjust their positions. This anticipatory shift is consistent with theoretical predictions that expected disclosure strengthens short-horizon investors’ incentives to acquire and trade on private information. We further document that stock prices reflect more firm-specific information leading up to disclosure and that improved liquidity at disclosure enables short-term investors to partially unwind their positions. Our paper offers novel evidence on how increases in the expected likelihood of disclosure shape investor behavior and the composition of firms’ investor bases.

We analyze how the materialization of physical climate risk in the institutional investors’ portfolios spurs a propagation effect on the information content of stock prices. Institutional investors with a relatively high portfolio exposure to natural disasters divest from disaster-hit stocks, decrease the trading intensity in non-hit stocks, and their trading decisions predict low medium-term returns. At the firm-level, institutional investors propagate the effects of disasters to non-hit stocks through reduced incorporation of firm-specific information, especially when the stocks represent a low portfolio weight. Combined, these results suggest that natural disasters trigger a rational reallocation of information-processing resources by institutional investors.
