We study the influence of unsecured debt (subdebt) and of bail-in debt on banks' risk-taking in a contingent claim model, while considering the bargaining between stockholders and debtholders. We show that replacing stock with subdebt: (1) leads to fewer risk-shifting events, but generates a...

Black and Cox (1976) claim that the value of junior debt is increasing in asset risk when the firm's value is low. We show, using closed-form solution, that the junior debt's value is hump-shaped. This has interesting implications for the market-discipline role of banks' junior debt (subdebt)

Our understanding of risk preferences can be sharpened by considering their evolutionary basis. The existing literature has focused on two sources of risk: idiosyncratic risk and aggregate risk. We introduce a new source of risk, heritable risk, in which there is a positive correlation between...

We study various decision problems regarding short-term investments in risky assets whose returns evolve continuously in time. We show that in each problem, all risk-averse decision makers have the same (problem-dependent) ranking over short-term risky assets. Moreover, in each problem, the...
