This paper investigates the patterns of directors' trades and returns around takeover announcements. We find that the pre-announcement net value (the difference between buy value and sell value) of directors' trading is positively related to acquirers' announcement period abnormal returns. This...

Disclosure of insider trading are ambiguous pieces of information, as liquidity traders may not assess whether the trades are motivated by significant privileged information related to the true share value. This paper establishes an algorithm, relying on Bayesian inference that represents the...

We present strong evidence of supra-competitive pricing of debtor-in-possession (DIP) loans to large firms in Chapter 11 bankruptcy. Over-collateralized and with super-priority, strong covenants, rollups, and debtor-funded monitoring costs, these loans are almost risk-free. Nonetheless, loan...
