We investigate whether suppliers adjust innovative supply chain investment following stock market signals about customers’ economic prospects. We show that suppliers increase R&D and investment in customer-related patents after positive market reactions to customers’ new product announcements. A battery of falsification tests suggest that spurious factors are unlikely to explain our results. Market signals about customers appear more important when information asymmetry is greater, when suppliers face greater competitive threats, and when suppliers are financially unconstrained. Our evidence suggests that the stock market can be a viable source of information to mitigate supply chain frictions.

Is bank financing compatible with innovation? We show that an exogenous enhancement in the value of borrowers’ patents, either through greater patent protection or creditor rights over collateral, results in cheaper loans. Using regression discontinuity design, we show that although R&D investment sharply drops following a financial covenant violation, the reduction is concentrated in firms with less productive R&D. Consequently, R&D reduction does not impair innovative output. Our results suggest that the property rights that patents confer to intellectual property and to lenders’ judicious exercise of control rights allow bank loans to be a viable means of financing for innovative firms.

We study the relation between state-level public corruption in the United States and firm-value and firms' disclosure policies. Consistent with our hypotheses, firms have significantly lower value (Tobin’s q) and informational transparency in more corrupt areas. Local corruption has a less negative effect on industries that sell primarily to the government, suggesting a quid pro quo between these firms and public officials. Several tests address endogeneity concerns: for example, firms located in different states but close to state borders are affected by differences in state-level corruption, indicating legal jurisdiction matters despite similar local conditions.

We review the effectiveness of various adjustment methods in correcting the truncation-bias in patents data and the implications for existing studies. The NBER patents-database was recently updated, extending the sample from 2006 to 2010. The updated sample is largely free of truncation-bias over the period covered by the NBER-2006 sample, allowing us to evaluate the bias-adjustment methods. We find that existing adjustments perform poorly towards the end of NBER-2006 sample. We re-examine multiple studies from the recent literature on innovation and show that findings based on the last few years of NBER-2006 data are not supported in the updated patents-database.

We examine managers’' disclosure decisions in response to non-fundamental price shocks. Using mutual fund fire sales as a source of market disruption, we show some firms respond by issuing earnings guidance. Others, especially firms with weaker performance and more short-term-oriented investors, engage in accrual-based earnings management. To identify the efficacy of firm disclosure choices, we examine passage of Sarbanes-Oxley and Regulation Fair Disclosure and show that they increased reliance on guidance rather than earnings management. The shift is associated with faster post-fire-sales price recovery, suggesting enhancing information disclosure rather than manipulation is effective in mitigating the effect of market disruptions.

Firms rely on patenting and trade secrecy to protect their intellectual property. We study how changes in the trade-off between patenting and secrecy affect firms’ stock liquidity and financing outcomes. We show that an international trade agreement (TRIPS) that strengthened patent protection led to a 10.2% increase in patenting, accompanied by a 14.0%–27.1% improvement in stock liquidity for firms in patent-reliant industries. This in turn allows the affected firms to increase equity financing by 1.9% and reduce leverage by 5.9%. Our results suggest that policies that promote use of patenting over secrecy can reduce informational frictions in equity markets.

We examine the recent rise of institutional investment in the single-family home rental market and its implications for renters’ welfare. Using institutional mergers to identify local exogenous variation in institutional landlords’ scale and market share, we show that rents increase in neighborhoods where both merging firms owned properties (i.e., overlapped neighborhoods) relative to other nonoverlapped neighborhoods. Meanwhile, the crime rate also significantly decreases in overlapped neighborhoods after mergers. Our findings suggest that while institutional landlords leverage their market power to extract greater surplus from renters, they also improve the quality of rental services by enhancing neighborhood safety.
