Equity capital allocation plays a particularly important role for financial institutions such as banks, who issue equity infrequently but have continuous access to debt capital. In such a context this paper shows that EVA and RAROC based capital budgeting mechanisms have economic foundations. We derive optimal capital allocation under asymmetric information and in the presence of outside managerial opportunities for an institution with a risky and a riskless division. It is shown that the results extend in a consistent manner to the multidivisional case of decentralized investment decisions with a suitable redefinition of economic capital. The decentralization leads to a charge for economic capital based on the division's own realized risk. Outside managerial opportunities increase the usage of capital and lead to overinvestment in risky projects; at the same time more capital is raised but risk limits are binding in more states. An institution with a single risky division should base its hurdle rate for capital allocated on the cost of debt. In contrast, the hurdle rate tends to the cost of equity for a diversified multidivisional firm. The analysis shows that hurdle rates have a common component in contrast to the standard perfect markets result with division-specific hurdle rates.

This paper examines the impact of the borrower–lender relationship on the explicit loan interest rate and collateral, as well as the correlation between loan interest rates and collateral. Using a simultaneous equation approach, we find that collateral has a statistically significant positive impact of 200 to 400 basis points on loan interest rates. We find this positive association to be stronger for personal (or outside) collateral than collateral provided by the firm's assets (or inside collateral). Finally, we find the economic impact of the borrower–lender relationship to be 21 basis points for one standard deviation increase in relationship length.

This paper assesses the impact of the ownership structure of banks and shareholder protection laws on bank valuations while controlling for differences in bank regulations. Except in a few countries with very strong shareholder protection laws, banks are not widely held. Rather, families or the State control banks. Furthermore, (i) larger cash-flow rights by the controlling owner boost valuations, (ii) stronger shareholder protection laws increase valuations, and (iii) greater cash-flow rights mitigate the adverse effects of weak shareholder protection laws on valuations. These results suggest that ownership structure is an important mechanism for governing banks.

The Basel Committee designed a system of risk weights (“standardised approach”) to measure the riskiness of banks' loan portfolios. We investigate its ability to adequately reflect risk through an analysis of the economic capital implied in corporate bond spreads. This is based on a dataset of issuance spreads, ratings and other relevant bond variables including 7232 eurobonds issued by an internationally-diversified sample during 1991–2003. Three main results emerge: the spread/rating relationship is strongly significant; the estimated spreads per rating class indicate a steeper risk/rating relationship than the one approved by the Basel Committee; no significant difference appears in the spread/rating relation of banks and non-financial firms issuers.
