In the business ethics literature, many argue that managerial decision making ought to be improved by more robust ethical concerns. Some see the virtue of “practical wisdom” as the key for improved managerial decision making. However, because of the epistemic limitations confronting decision makers in the face of irreducible market complexity, there is a risk that practical wisdom, employed in the context of day-to-day managerial decision making, becomes an impractical concept. Nevertheless, if the attempt to incorporate virtue ethics (and its related concepts) into business practices is laudable, if indeed a virtuous life is worth pursuing and practical wisdom plays an essential role toward that end, it is important to attempt to salvage practical wisdom and uncover its appropriate usage. Thus, this article pursues two major ends. First, upon surveying some of the prominent and standard usages of the term, it articulates concerns, rooted in epistemic limitations, about the way that practical wisdom appears in business ethics literature. Second, it offers a new way forward for understanding “practical wisdom.” By contextualizing day-to-day, rule-based managerial decision making within the ethical value of the market order, practical wisdom reappears as the higher-order capacity to pursue vocations, as morally worthwhile projects, in business. 相似文献

This study focuses on the success factors of necessity immigrant entrepreneurs. It proposes a profile for the necessity immigrant entrepreneur as well as for the opportunity immigrant entrepreneur. It clarifies the concept of success for immigrant entrepreneurs and suggests that the concept of survival is more appropriate for the necessity immigrant entrepreneurs and should mainly be measured by the age of the business, while the traditional concept of success is relevant for the opportunity immigrant entrepreneur and can be measured by the usual quantitative performance indicators. Based on different existing theories, the study suggests a theoretical explanation of the survival factors of necessity immigrant entrepreneurs. This contributed to propose a theoretical model of survival factors of necessity immigrant entrepreneurs. This model, which represents the major contribution of this study, suggests five categories of survival factors: ethno‐cultural factors, financial factors, managerial factors, psycho‐behavioral factors, and institutional factors. © 2010 Wiley Periodicals, Inc. 相似文献

Abstract Growing research interest has been shown in finite-time ruin probabilities for discrete risk processes, even though the literature is not as extensive as for continuous-time models. The general approach is through the so-called Gerber-Shiu discounted penalty function, obtained for large families of claim severities and discrete risk models. This paper proposes another approach to deriving recursive and explicit formulas for finite-time ruin probabilities with exponential or geometric claim severities. The proposed method, as compared to the general Gerber-Shiu approach, is able to provide simpler derivation and straightforward expressions for these two special families of claims. 相似文献

Abstract It is well known that reinsurance can be an effective risk management tool for an insurer to minimize its exposure to risk. In this paper we provide further analysis on two optimal reinsurance models recently proposed by Cai and Tan. These models have several appealing features including (1) practicality in that the models could be of interest to insurers and reinsurers, (2) simplicity in that optimal solutions can be derived in many cases, and (3) integration between banks and insurance companies in that the models exploit explicitly some of the popular risk measures such as value-at-risk and conditional tail expectation. The objective of the paper is to study and analyze the optimal reinsurance designs associated with two of the most common reinsurance contracts: the quota share and the stop loss. Furthermore, as many as 17 reinsurance premium principles are investigated. This paper also highlights the critical role of the reinsurance premium principles in the sense that, depending on the chosen principles, optimal quota-share and stop-loss reinsurance may or may not exist. For some cases we formally establish the sufficient and necessary (or just sufficient) conditions for the existence of the nontrivial optimal reinsurance. Numerical examples are presented to illustrate our results. 相似文献

Abstract This article discusses methods of risk-neutralizing multivariate probability distributions by applying exponential tilting to the joint probability density function with respect to a set of reference risks. To ensure consistent interpretations of the exponential tilting parameters, a normalization procedure is performed on the reference risks via percentile mapping to standard normal variables. The article establishes links between normalized exponential tilting and multivariate probability distortions. It provides efficient methods for computing risk-neutralized multivariate probability distributions, and it gives illustrative examples in pricing contingent claims on multiple risks. 相似文献
