This Paper analyses the determinants of regulatory capital (the minimum required by regulation) and economic capital (the capital that shareholders would choose in absence of regulation) in the context of the single risk factor model that underlies the New Basel Capital Accord (Basel II). The...

We examine the interdependency between loan officer compensation contracts and commercial bank internal reporting systems (IRSs). The optimal incentive contract for bank loan officers may require the bank headquarters to commit not to act on certain types of information. The headquarters can...

In this paper, we examine the relationship between banks’ approval for the internal ratings-based (IRB) approaches of Basel II and the ratio of risk-weighted over total assets. Analysing a panel of 115 banks from 21 OECD countries that were eventually approved for applying the IRB to their...

We study the effects of a bank’s engagement in trading. Traditional banking is relationship-based: not scalable, long-term oriented, with high implicit capital, and low risk (thanks to the law of large numbers). Trading is transactions-based: scalable, short-term, capital constrained, and with...

The paper studies risk mitigation associated with capital regulation, in a context where banks may choose tail risk assets. We show that this undermines the traditional result that higher capital reduces excess risk-taking driven by limited liability. Moreover, higher capital may have an...

This paper reports estimates of the long-run costs and benefits of banks funding more of their assets with loss-absorbing capital, or equity. Measuring those costs requires careful consideration of a wide range of issues about how shifts in funding affect required rates of return and on how...

We investigate the optimal regulation of financial conglomerates that combine a bank and a non-bank financial institution. The conglomerate’s risk-taking incentives depend upon the level of market discipline it faces, which in turn is determined by the conglomerate’s liability structure. We...

We consider a model in which banks face two moral hazard problems: 1) asset substitution by shareholders, which can occur when banks make socially-inefficient, risky loans; and 2) managerial under-provision of effort in loan monitoring. The privately-optimal level of bank leverage is neither too...

For an international sample of banks, we construct measures of a bank’s absolute size and its systemic size defined as size relative to the national economy. We then examine how a bank’s risk and return, its activity mix and funding strategy, and the extent to which it faces market...

We analyse a model in which bank deposits are insured and there is an exogenous cost of bank capital. The former effect results in bank over-investment and the latter in under-investment. Regulatory capital requirements introduce investment distortions, which are a constrained optimal response...
