We study the behavior of a financial institution subject to capital requirements based on self-reported VaR measures, as in the Basel Committee's Internal Models Approach. We view these capital requirements and the associated backtesting procedure as a mechanism designed to induce financial institutions to reveal the risk of their investments and to support this risk with adequate levels of capital. Accordingly, we consider the simultaneous choice of an optimal dynamic reporting and investment strategy. Overall, we find that VaR-based capital requirements can be very effective not only in curbing portfolio risk but also in inducing revelation of this risk.

Managements (“insiders”) of many corporations, especially small or newly-public firms, invest considerable resources in investor relations. We develop a model to explore the incentives of insiders to undertake such costly investments. We point out that insiders may undertake such investments not necessarily to improve the share price, but to enhance the liquidity of their block of shares. This leads to a divergence of interest between insiders and dispersed outside shareholders regarding investor relations. Our model predicts that the demographics of insiders (e.g. liquidity needs, size of equity stakes) are important determinants of the extent of investor relations across firms.

Using a panel data set (1997–1999) for 235 publicly listed companies in the People's Republic of China (PRC), this study tests empirically whether the purchase of property insurance mitigates principal-agent (agency) incentive conflicts. In contrast to prior studies, we first estimate a probit insurance participation decision model and then a fixed-effects insurance volume decision model (with Heckman's sample selection correction) in order to shed light on the determinants of both property insurance participation and volume decisions. Our results suggest that a major motivation for the corporate purchase of insurance in China appears to be the mitigation of agency conflicts. Additionally, various ownerships seem to have different impacts on the corporate purchase of insurance in China. Moreover, the results show that the same factor can have different impacts on the insurance participation and volume decisions, and that binding financial conditions may be a key factor accounting for such observed differences.
