This paper assesses the impact on consumption and debt repayment from a credit card promotional campaign offering cash-back rewards. Using account-level administrative data from a large U.S. financial institution, we employ a generalized difference-in-differences design and find that even with a small 1% cash-back incentive, the rewards program leads to a substantial change in consumer behavior. Cardholders joining the rewards program increase their credit card spending by 32% and their debt by 8%, with such behavior persisting in the long run. Evidence from credit bureau confirms that the higher spending and debt are not driven by cross-card substitution or similar promotions by other card issuers. Different consumer segments respond differentially to the promotional campaign. Consumers with a higher level of liquidity constraints and who are less financially literate demonstrate more pronounced responses.

Anti-recharacterization laws significantly increase the rights of securitization creditors by allowing the buyers of securitized assets to exclusively and immediately seize collateral in bankruptcy. However, strengthening the rights of securitization creditors can limit other creditors’ ability to recover loans. We find that, after a state adopts an anti-recharacterization law, local banks operating in the same state accrue more loan loss provisions, tighten their loan contracts, and incur higher future loan charge-offs. These findings are consistent with the argument that a safe harbor for securitization transactions advantages Wall Street-style structured finance at the expense of Main Street-style lending.

We hypothesize that social trust, in mitigating contracting incompleteness, may have an important effect on the activeness and effectiveness of delegated portfolio management. Using a complete sample of worldwide open-end mutual funds, we find that trust is positively associated with the activeness of funds and that trust-related active share delivers superior performance (e.g., approximately 2% per year for cross-border investments). Moreover, “trust in the market” and “trust in managers” play important yet different roles for different types of cross-border delegated portfolio management. Our results suggest that trust acts as a fundamental building block for delegated portfolio management.

This paper investigates the effect of frictions in consumption taxes on firms' product mix decisions. We use a stacked difference-indifferences approach that exploits the staggered transition from a sales tax with the risk of tax cascading to a value added tax (VAT) with credits on inputs across states in India, as well as detailed data on listed manufacturing firms' production decisions. We find that the switch to a VAT system induces affected firms to narrow their product scope and to reduce vertical integration. That is, firms cut the internal production of input goods and instead focus their production on their best-performing products. Firms affected by the switch to VAT reduce their firm size and are more likely to outsource production of input goods. We also show that this vertical disintegration results in lower manufacturing costs, higher profitability and firm value, and increased investment efficiency for affected firms. Overall, the paper shows that alleviating frictions in sales tax or VAT systems can reduce investment and productivity distortions and improve the allocation of capital across firms.

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.

Inspired by the recent health science findings that air pollution affects mental health and cognition, we examine whether air pollution can intensify the cognitive bias observed in the financial markets. Based on a proprietary data set obtained from a large Chinese mutual fund family consisting of complete trading information for more than 773,198 accounts in 247 cities, we find that air pollution significantly increases investors’ disposition effects. Analysis based on two plausible exogenous variations in air quality (the vast dissipation of air pollution caused by strong winds and the Huai River policy) supports a causal interpretation. Mood regulation provides a potential mechanism.
