    Using textual analysis and comparing cybersecurity-risk disclosures of firms that were hacked to others that were not, we propose a novel firm-level measure of cybersecurity risk for all US-listed firms. We then examine whether cybersecurity risk is priced in the cross-section of stock returns. Portfolios of firms with high exposure to cybersecurity risk outperform other firms, on average, by up to 8.3% per year. At the same time, high-exposure firms perform poorly in periods of high cybersecurity risk. Reassuringly, the measure is higher in information-technology industries, correlates with characteristics linked to firms hit by cyberattacks, and predicts future cyberattacks

    We study the effects of unexpected changes in trade policy uncertainty (TPU) on the U.S. economy. We construct three measures of TPU based on newspaper coverage, firms' earnings conference calls, and aggregate data on tari rates. We document that increases in TPU reduce investment and activity using both firm-level and aggregate macroeconomic data. We interpret the empirical results through the lens of a two-country general equilibrium model with nominal rigidities and firms' export participation decisions. In the model as in the data, news and increased uncertainty about higher future tariffs reduce investment and activity

    There is a robust literature documenting the importance of physician practice style (e.g., the propensity to perform certain operations) in explaining outcomes related to patients' physical health. Yet little is known about the role of physicians in explaining patients' mental health outcomes. This paper uses novel data on doctor note text together with natural language processing techniques to estimate and document heterogeneity in physician practice style for diagnosing Attention Deficit Hyperactivity Disorder (ADHD). I find significant variation in both diagnostic intensity (the mean propensity to diagnose) and diagnostic compliance (the weight that physicians place on medical guidelines). Physician characteristics can explain some of this heterogeneity. Specifically, both female physicians and recent graduates have higher diagnostic compliance and lower diagnostic intensity than their respective counterparts. Mental health diagnostic errors lead to excess medical and societal spending. Given the costs of such errors, the findings in this paper encourage a re-evaluation of the mental health identification process, though perhaps targeted at specific sub-groups of physicians.

    Exploiting the 2009 amendments to Regulation S-K, we provide unique evidence on the first-time disclosure of the reasons firms state for combining (separating) the roles of CEO and chairman. The stated reasons support both agency theory and organization theory. They are more numerous and comprise more words, including more positive words, for firms with duality. Examining the announcement returns to firms’ disclosures, we find that investors evaluate the most frequently cited reasons for CEO duality by considering the firm’s characteristics.

    Increased interdependencies across countries have led to calls for greater harmonization of regulations to prevent local shock from spilling over to other countries. Using the rulemaking process of the Basel Committee on Banking Supervision (BCBS), this paper studies the process through which harmonization is achieved. Through leaked voting records, we document that the probability of a regulator opposing an initiative increases if their domestic national champion (NC) opposes the new rule, particularly when the proposed rule disproportionately affects them. Next, we show that smaller banks, even when they collectively have a higher share in the domestic market, do not have any impact on regulators' stand - suggesting that regulators' support for NCs is not guided by their national interest. Further, we find the effect is driven by regulators who had prior experience working in large banks. Finally, we show this unanimous decision-making process results in significant watering down of proposed rules. Overall, the results highlight the limits of harmonization of international financial regulation.

    Fund companies regularly send shareholder letters to their investors. We use textual analysis to investigate whether these letters' writing style influences fund flows and whether it predicts performance and investment styles. Fund investors react to the tone and content of shareholder letters: A less negative tone leads to higher netflows. Thus, fund companies can use shareholder letters as a tactical instrument to influence flows. However, at the same time, a dishonest communication that is not consistent with the fund's actual performance decreases flows. A positive writing style predicts higher idiosyncratic risk as well as more style bets, while there is no consistent predictive power for future performance.
