    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.

    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.

    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.
