Now in prospect is a major revision of international bank capital regulations that would embody recent advances in credit risk measurement and management. Previous regulations have been simpler in structure, with a primary goal of getting capital requirements right on average, and thus have...

Although nation-based systems of financial regulation constitute a second-best approach to global welfare maximization, treacherous accountability problems must be acknowledged and resolved before regulatory cooperation can deal fairly and efficiently with cross-border issues. To track and...

We study a modification of the Diamond and Dybvig (1983) model in which the bank may hold a liquid asset, some depositors see sunspots that could lead them to run, and all depositors have incomplete information about the bank's ability to survive a run. The incomplete information means that the...

As financial institutions and markets transact more and more cross-border business, gaps and flaws in national safety nets become more consequential. Because citizens of host (home) countries may be made to pay for mistakes made in the home (host) country, Basel's lead-regulator paradigm...

This paper models and estimates ex ante safety-net benefits at a sample of large banks in US and Europe during 2003-2008. Our results suggest that difficult-to-fail and unwind (DFU) banks enjoyed substantially higher ex ante benefits than other institutions. Safety-net benefits prove...

Financial safety nets are incomplete social contracts that assign responsibility to various economic sectors for preventing, detecting, and paying for potentially crippling losses at financial institutions. This paper uses the theories of incomplete contracts and sequential bargaining to...

Under the New Basel Accord bank capital adequacy rules (Pillar 1) are substantially revised but the introduction of two new "Pillars" is, perhaps, of even greater significance. This paper focuses on Pillar 2 which expands the range of instruments available to the regulator when intervening with...

Limited liability and asymmetric information between an investment bank and its lenders provide an incentive for a bank to undercapitalise and finance overly risky business projects. To counter this market failure, national governments have imposed solvency constraints on banks. However, these...

Countercyclical capital buffers (CCyBs) are an old idea recently resurrected. CCyBs compel banks at the core of financial systems to accumulate capital during expansions so that they are better able to sustain operations during downturns. To gauge the potential impact of modern CCyBs, we compare...

We propose a theory of regulatory arbitrage by banks and test it using trust preferred securities (TPS) issuance. From 1996 to 2007, U.S. banks in the aggregate increased their regulatory capital through issuance of TPS while their net issuance of common stock was negative due to repurchases. We...
