Recent advances in the theory of credit risk allow the use of standard term structure machinery for default risk modeling and estimation. The empirical literature in this area often interprets the drift adjustments of the default intensity's diffusion state variables as the only default risk premium. We show that this interpretation implies a restriction on the form of possible default risk premia, which can be justified through exact and approximate notions of "diversifiable default risk." The equivalence between the empirical and martingale default intensities that follows from diversifiable default risk greatly facilitates the pricing and management of credit risk. We emphasize that this is not an equivalence in distribution, and illustrate its importance using credit spread dynamics estimated in Duffee (1999) . We also argue that the assumption of diversifiability is implicitly used in certain existing models of mortgage-backed securities. 相似文献

A bstract . A simple framework is presented for the analysis of the local employment, income, sales , and local government impacts of landing North Sea gas at either of two Norwegian kommunes (municipalities). These impacts indicate the different forms of economic change arising from a major economic development event. The average annual net change in these economic measures is estimated for the operational phase of a gas terminal. The analysis indicated substantial differences in local and regional net gains. Both sites yielded positive neteconomic gains, which means noneconomic and national considerations become key decision determinates. These national issues provide the setting to judge the local/regional net gains. The unresolved questions include the national benefits and costs of the landing decision given the small scale of the Norwegian economy, potential future gas finds, and a fully employed economy. 相似文献

There is general agreement that attitudes towards the entrepreneur, entrepreneurial activity, and its social function are determinant factors for university students to decide an entrepreneurial career.This empirical study aims at assessing and comparing the attitudes of university students towards entrepreneurship and enterprise formation in Catalonia and Puerto Rico, using a sample of 837 and 435 students, respectively.Results reveal a positive entrepreneur’s image. Both samples have a favorable perception of desirability of new venture creation, although the perception of feasibility is by far not so positive and only a small percentage has the firm intention to create a new company. 相似文献

The Theory of Socially Embedded Games: Applications and Extensions to Open and Closed Games 总被引:1,自引:0,他引:1
An earlier article, drawing on the mathematical theory of rules and rule complexes, extends and generalizes game theory (GGT). The theory has been used to conceptualize and analyze diverse social relationships, roles, and games as particular types of rule complexes.For instance, a social role, as a major basis of a parent's action in a game, consists of at least four key components – which are mathematical objects – in the determination of action: value complex, model of reality (including beliefs and knowledge bases), a repertoire of acts, routines, programs, and strategies, and modality, a role-specific algorithm for determining or generating action in game settings. This article applies and extends GGT in analyses of a market bargaining game (a type of open game) and of the classical game of prisoners' dilemma (a type of closed game). The applications show the concrete effects of social embeddedness on game structuring, game interaction patterns and outcomes, and social equilibria. 相似文献

This article introduces this special issue of theEmployee Responsibilities and Rights Journal on recent work exploring Albert O. Hirschman's Exit, Voice, and Loyalty model of dissatisfaction. This special issue provides a forum for researchers and theorists with various perspectives on the model to present their ideas in one place. There are six original articles in this issue, and one discussion piece. While these articles do not resolve the controversies surrounding the Exit, Voice, and Loyalty model, they do provide a clear picture of the current status of research and theory on dissatisfaction in organizations from this perspective. 相似文献

The underlying “architecture of the decision to pursue a degree in psychology was quantified using the Method of Sorting technique
to identifying the critical issues necessary to make this choice. Multidimentsional scaling procedures were employed to construct
a three-dimensional map representing the relationships between reasons for selecting psychology as a major. Freshman and senior
psychology majors (N = 165) from a regional university and a large research-based institution rated the relative importance of items in their
decision-making process. Hierarchical clustering procedures revealed seven different groups of students. Although significant
differences associated with class standing were not found, institutional affiliation did influence cluster composition. Reflecting
local emphases, students at the regional institution had a greater interest in Counseling Psychology, whereas those at the
research-based school focused on Clinical Psychology. This semantic map and the associated item clusters arising from psychology
student data provides an empirical basis for, amongst other things, course selection, faculty-initiated program design or
revision, strategic niche marketing, and student retention. 相似文献
