Bankruptcy, Counterparty Risk, and Contagion 总被引:2,自引:0,他引:2
This paper provides a unifying framework for the modeling ofvarious types of credit risks such as contagion effects. Weargue that Markov chains can efficiently be used to tackle theseproblems. However, our approach is not limited to pricing problemswith contagion. On the theoretical side, we derive pricing formulasfor three building blocks that are generalizations of contingentclaims studied in Lando (1998). These claims can be thoughtof as atoms forming the basis for all credit risk payments.Furthermore, we demonstrate that, in general, all contingentclaims exposed to credit risk satisfy a system of partial differentialequations. This is the key result to calculate prices of creditrisk claims explicitly and efficiently. 相似文献

This article contrasts and compares statistics from the UK small firm sector in general with those related to small firms within the hotel industry. In doing so, it is clearly illustrated that there is a need to focus research, resultant policy and strategy on the specific issues facing small firms at a sub-sector level, rather than assuming a homogeneity of the small firm population in general. The paper concludes that the plight of the small firm operating within the hotel industry is dire and questions what the future holds. 相似文献

Internationally, the small firm community has been the focus of attention from academics and policy makers for several decades. On the other hand, franchising of services is a relative newcomer, particularly in the United Kingdom, and has not received the attention that this form of business organisation warrants. This article investigates the extent to which franchising represents the intelligent leverage of resources by ‘small firm’ owner-operator franchisees, focusing on one major ‘benchmark’ franchisor in the UK – McDonald's Restaurants Ltd. The article enables the exploration of the profile of individuals attracted to franchising and the associated resources, costs, tensions and contradictions, and moves discussion towards conclusions based on a resource scarcity/efficiency thesis from the dual perspectives of the franchisee and franchisor. 相似文献

We study the welfare effect of tax-optimizing portfolio decisions in a life cycle model with unspanned labor income and realization-based capital gain taxation. For realistic parameterizations of our model, certainty equivalent welfare gains from fully tax-optimized portfolio decisions are less than 2% of present financial wealth and lifetime income compared to a heuristic portfolio policy ignoring the taxation of profits (capital gains, interest and dividend payments). Compared to a heuristic portfolio policy that only ignores the realization-based feature of capital gain taxation and instead assumes mark-to-market taxation, these gains are less than 0.5%. That is, our work provides a justification for ignoring taxes in life cycle portfolio choice problems – a wide-spread assumption in that literature. However, if capital gains are forgiven at death (as in the U.S.), investors with strong bequest motives face substantial welfare costs when not tax-optimizing their portfolio decisions towards the end of the life cycle. 相似文献

There are many situations where two interacting individuals can benefit from coordinating their actions. We examine the endogenous choice of partners in such social coordination games and the implications for resulting play. We model the interaction pattern as a network where individuals periodically have the discretion to add or sever links to other players. With such endogenous interaction patterns we see multiple stochastically stable states of play, including some that involve play of equilibria in the coordination game that are neither efficient nor risk-dominant. Thus the endogenous network structure not only has implications for the interaction pattern that emerges, but it also has a significant impact on the play in the coordination game relative to what would arise if the same interaction network were exogenous. 相似文献

This paper investigates the relative importance of social responsibility criteria in determining organizational effectiveness. The organizational effectiveness menu was used as a questionnaire with a sample of 151 senior undergraduates. Each respondent was asked to rate the importance of the criteria from three constituent perspectives within a service organization: (1) as a manager, (2) as an investor, (3) as an employee. Later, a subsample of students (n=61) responded to the same questionnaire acting as a manager in an assigned case study. The results indicated that students acting as managers, investors, or employees rate social responsibility criteria among the least important of the determinants of organizational effectiveness. Moreover, while specific situations may call for changes in the relative importance of these criteria, social responsibility criteria were not viewed, generally, as the most important determinants of organizational effectiveness.Kenneth L. Kraft is currently an Associate Professor of Management at Old Dominion University in Norfolk, VA. His recent papers explore the relationships between strategy, structure, social responsibility, and organizational effectiveness in a variety of settings. 相似文献

Mapping the benefits and costs associated with process innovation: The case of RFID adoption 总被引:2,自引:0,他引:2
The successful implementation of any innovation requires an understanding of its benefits and costs. This study examines the changes in the magnitude of costs and benefits associated with technology process innovation adoption as the innovation diffuses across different industries. Using RFID as an exemplar technology, the study shows that the magnitude of benefits and costs associated with technological process innovation adoption within different industries varies as technology diffuses beyond early adopters to the early majority. During the early stages of technology evolution, the development cost, the cost of capital, ethical costs and simple direct implementation costs (in the form of the cost of tags) predominate. As a dominant design emerges the profile of costs changes with the emphasis on initiation costs, more holistic direct implementation costs and indirect implementation costs. A similar change in the emphasis of benefits is observed, with a shift from direct to indirect benefits being noticeable as the technology moves from early adopters to early majority adopters. Our findings help to explain the difficulties in consistently measuring innovation outcomes observed in the innovation implementation literature, and emphasize the need to take into consideration the stage of technology development as a significant factor that influences the realised outcomes from innovation implementation. 相似文献
