Banks operating under Value-at-Risk constraints give rise to a welldefined aggregate balance sheet capacity for the banking sector as a whole that depends on total bank capital. Equilibrium risk and market risk premiums can be solved in closed form as functions of aggregate bank capital. We...

We study rights offerings using a sample of 8,238 rights offers announced during 1995-2008 in 69 countries. Although shareholders prefer having the option to trade rights, issuers deliberately restrict tradability in 38% of the offerings. We argue that firms restrict rights trading to avoid the...

This paper studies the efficiency of collusion between supervisors and supervisees. Building on Tirole (1986)’s results that deterring collusion with infinitely risk averse supervisors is impossible, while it is costless to do so under risk neutrality, we develop here a theory of collusion...

We propose a theory of supervision with endogenous transaction costs. A principal delegates part of his authority to a supervisor who can acquire soft information about an agent's productivity. If the supervisor were risk-neutral, the principal would simply make the better informed supervisor...

‘Safe harbour’ is shorthand for a bundle of privileges in insolvency which are typically afforded to financial institutions. They are remotely comparable to security interests as they provide a financial institution with a considerably better position as compared to other creditors should...

Given the opportunity to buy IPO shares of uncertain value at a fixed price, potentially informed investors have an incentive to refuse to participate in offerings the underwriter happens to overprice. We show that an underwriter can efficiently resolve this problem by entering into a repeat...

This paper analyzes banks’ choice between lending to firms individually and sharing lending with other banks, when firms and banks are subject to moral hazard and monitoring is essential. Multiple-bank lending is optimal whenever the benefit of greater diversification in terms of higher...

This paper shows how separation of ownership and control may arise as a response to overload costs, despite agency costs, and how conglomerates arise as solution to information asymmetries in capital markets. In a context where entrepreneurs have the ability to run projects and improve their...
