The Determinants of Enterprise Risk Management: Evidence From the Appointment of Chief Risk Officers
Enterprise risk management (ERM) has captured the attention of risk management professionals and academics worldwide. Unlike the traditional "silo-based" approach to corporate risk management, ERM enables firms to benefit from an integrated approach to managing risk that shifts the focus of the risk management function from primarily defensive to increasingly offensive and strategic. Despite the heightened interest in ERM, little empirical research has been conducted on the topic. This study provides an initial attempt at identifying the determinants of ERM adoption. We construct a sample of firms that have signaled their use of ERM by appointing a Chief Risk Officer (CRO) who is charged with the responsibility of implementing and managing the ERM program. We use a logistic regression framework to compare these firms to a size- and industry-matched control sample. While our results suggest a general absence of differences in the financial and ownership characteristics of sample and control firms, we find that firms with greater financial leverage are more likely to appoint a CRO. This finding is consistent with the hypothesis that firms appoint CROs to reduce information asymmetry regarding the firm's current and expected risk profile. 相似文献

This paper introduces a simple, yet rich, measure of efficiency changes based on the revenue-generating-ability (RGA) principle. Using this principle, we explain the connections between efficiency changes and the variables, such as pretax profits, interest expense, non-interest expense, profit margins, loan loss provision, and asset quality. These connections are used to explain earnings differences between small and large commercial banks. 相似文献

Statistical inference based on the Weibull distribution, a distribution widely used in reliability and survival analysis,
is usually difficult as it often involves numerical computation and approximation. However, this distribution can be transformed
to near-normality by a simple power transformation. Based on this transformation, a prediction interval (PI) for its median
can be easily constructed through an inverse transformation. The procedure for selecting the best power transformation through
minimizing Kullback-Leibler information is described. The property of this transformation-based PI is investigated. Simple
correction factors are also proposed. It is shown that the transformation-based PI with corrections performs well, irrespective
of the sample size and parameter values. Simulation results show that the new PI generally outperforms the existing PI. Numerical
examples are given for illustration. 相似文献

The conceptual model presented in this article argues that corporations exhibit specific behaviors that signal their true level of moral development. Accordingly, the authors identify five levels of moral development and discuss the dynamics that move corporations from one level to another. Examples of corporate behavior which are indicative of specific stages of moral development are offered.R.

An Erratum for this article has been published in Journal of Applied Econometrics 18(2) 2003, 249 Previous empirical work on corporate growth rates using cross‐section or short‐panel econometric techniques suggests that growth rates are random but that some degree of mean reversion exists. This means that size differences between firms are transitory. Another, more natural way to explore the long‐run distribution of firm sizes is to examine data on the growth of particular firms over long periods of time. Using a sample of 147 UK firms observed continually for more than 30 years, our conclusions are that growth rates are highly variable over time and that differences in growth rates between firms do not persist for very long. Further, firms show no tendency to converge to either a common size or to a pattern of stable size differences over time. These results are compared and contrasted with standard approaches that suggest that firms reach and maintain stable positions in a skewed size distribution.

The impact of demand growth on the collusion possibilities is investigated in a Cournot supergame where market growth may trigger future entry and the collusive agreement is enforced by the most profitable ‘grim trigger strategies’ available. It is shown that even in situations where perfect collusion can be sustained after entry, coping with a potential entrant in a market which is growing over time may completely undermine any pre‐entry collusive plans of the incumbent firms. This is because, before entry, a deviation and the following punishment phase may become more attractive thanks to their additional effect in terms of delaying entry. 相似文献

Financial flows between center and region are analyzed on the example of the Republic of Buryatia. Significant changes are shown to have occurred in the interbudgetary relations between the federal center and the region, which are associated with a revised delineation of authorities between different levels of authority. It has been the key factor in changing the sources and volumes of financial flows. The analysis is largely focused on the relations between the region and its municipalities. 相似文献

The general design for the real-time electricity market presented in this paper optimizes and prices both real and reactive
power simultaneously in an AC setting, where all assets—generation, load and transmission—are allowed to bid and are financially
settled at the locational price times energy consumed or produced. The result is that transmission lines are compensated for
both capacity and admittance, providing incentives for efficient operation of transmission-related assets such as FACTS devices,
if price-taking behavior is assumed. Losses are incorporated into the design and become an operating cost for transmission.
The market design is shown to be revenue neutral and, under some assumptions, nonconfiscatory.
