Monitoring, liquidation, and security design

By identifying the possibility of imposing a creditable threatof liquidation as the key role of informed (bank) finance ina moral hazard context, we characterize the circumstances underwhich a mixture of informed and uninformed (market) financeis optimal, and explain why bank debt is typically secured,senior, and tightly held. We also show that the effectivenessof mixed finance may be impaired by the possibility of collusionbetween the firms and their informed lenders, and that in theoptimal renegotiation-proof contract informed debt capacitywill be exhausted before appealing to supplementary uninformedfinance.     

Loan pricing under Basel capital requirements

We analyze the loan pricing implications of the reform of bank capital regulation known as Basel II. We consider a perfectly competitive market for business loans where, as in the model underlying the internal ratings based (IRB) approach of Basel II, a single risk factor explains the correlation in defaults across firms. Our loan pricing equation implies that low risk firms will achieve reductions in their loan rates by borrowing from banks adopting the IRB approach, while high risk firms will avoid increases in their loan rates by borrowing from banks that adopt the less risk-sensitive standardized approach of Basel II. We also show that only a very high social cost of bank failure might justify the proposed IRB capital charges, partly because the net interest income from performing loans is not counted as a buffer against credit losses. A net interest income correction for IRB capital requirements is proposed.     

A model of takeovers of foreign banks

This paper investigates the determinants of the takeover of a foreign bank by a domestic bank whereby the former becomes a branch of the latter. Each bank is initially supervised by a national agency that cares about closure costs and deposit insurance payouts, and may decide the early closure of the bank on the basis of supervisory information. Under the principle of home country control, the takeover moves responsibility for both the supervision of the foreign bank and the insurance of the foreign deposits to the domestic agency. It is shown that the takeover is more likely to happen if the foreign bank is small (relative to the foreign banking market) and its investments are risky (relative to those of the domestic bank). Moreover, the takeover is in general welfare improving for both countries.
