Lenders are reluctant to finance firms' innovation activities because such activities tend to be opaque, with a high likelihood of negative outcomes that could hamper loan repayment. We posit that public credit registries (PCRs), which play an important role in credit information sharing in many countries, can facilitate financing by reducing adverse selection and moral hazard and increasing bank competition. Using the staggered establishment of PCRs in different countries and an international firm–patent data set, we find that credit information sharing positively affects firm innovation, especially in firms that experience a larger increase in bank debt financing after the establishment of a PCR. This finding is consistent with the notion that credit information sharing promotes firm innovation by easing bank debt financing frictions. We also find a stronger effect in countries that experience a large increase in bank competition after the establishment of a PCR—consistent with increased bank competition serving as a channel through which credit information sharing facilitates bank debt financing, thereby generating a positive effect on firm innovation. The positive effect is more pronounced when the established PCR has features that promote credit information sharing. It is also more pronounced for opaque firms and firms in innovation‐intensive industries, indicating that credit information sharing helps to reduce financing frictions. Finally, we posit and find evidence that firm efficiency in transforming innovation inputs into outputs improves after the establishment of a PCR. Overall, our paper offers novel insights into how credit information sharing facilitates firm innovation.

Credit information sharing allows creditors to obtain borrowers' relevant credit information, and it can improve borrowers' investment outcomes that are funded by debt. Using reforms to European countries' public credit registries (PCRs) to capture mandated information sharing among creditors, we examine the impact of such sharing on firms' investment efficiency. We find that information sharing enhances firms' investment efficiency, which we measure by their investment‐ q sensitivity. This finding is consistent with credit information sharing enabling creditors to better screen borrowers to mitigate adverse selection and enhancing borrower discipline to avoid a bad credit record, which leads to the borrower making more efficient investments. We also document that the information sharing effect is more pronounced when firms rely more on debt financing, when the shared credit information is more accessible, when firms' information environment is more opaque, and when there is a greater information monopoly in the banking system. We offer supplementary evidence that the effect is also more salient when PCRs have characteristics that suggest more effective credit information sharing. Overall, our paper offers new insight into whether and how information sharing in credit markets enhances firms' investment efficiency. More broadly, it highlights how making more borrower information available to creditors can have important economic spillover effects on firm outcomes.

We examine whether intellectual property protection facilitates the greater incorporation of firm-specific information into the stock price. Employing the staggered, country-level adoption of the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), we find that after adoption, stock prices become less synchronous, consistent with more firm-specific information being impounded into the stock price. We further show that this effect is more pronounced for more innovative firms, firms in countries with stronger law enforcement, and firms with more financial analyst coverage. Finally, we document that TRIPS induces a richer information environment characterized by more management forecasts and media coverage.
