We exploit the impact of hurricane Katrina on insurance companies to study the relationship between bondholder concentration and credit risk. Redemption-driven sales by property and casualty (re)insurance companies exposed to hurricane Katrina are associated with a large drop in bondholder concentration faced by corporate bond issuers. Exploiting this shock to capture exogenous variation in bondholder concentration, we find that greater bondholder concentration is associated with higher bond yield spreads, as well as with firm characteristics associated with credit risk.

We examine the impact of overconfidence on compensation structure. Our findings support the exploitation hypothesis: firms offer incentive-heavy compensation contracts to overconfident Chief Executive Officers (CEOs) to exploit their positively biased views of firm prospects. Overconfident CEOs receive more option-intensive compensation and this relation increases with CEO bargaining power. Exogenous shocks (Sarbanes-Oxley Act of 2002 (SOX) and Financial Accounting Standard (FAS) 123R) provide additional support for the findings. Overconfident non-CEO executives also receive more incentive-based pay, independent of CEO overconfidence, buttressing the notion that firms tailor compensation contracts to individual behavioral traits such as overconfidence.
