Theoretically-driven, market-based contingent claims models have recently been applied to the field of corporate insolvency prediction in an attempt to provide the art with a theoretical methodology that has been lacking in the past. Limited studies have been carried out in order directly to compare the performance of these models with that of their accounting number-based counterparts. We use receiver operating characteristic curves to assess the efficacy of thirteen selected models using, for the first time, post-IFRS UK data; and investigate the distributional properties of model efficacy. We find that the efficacy of the models is generally less than that reported in the prior literature; but that the contingent claims models outperform models which use accounting numbers. We also obtain the counter-intuitive finding that predictions based on a single variable can be as efficient as those which are based on models which are far more complicated – in terms of variable variety and mathematical construction. Finally, we develop and test a naïve version of the down-and-out-call barrier option model for insolvency prediction and find that, despite its simple formulation, it performs favourably compared alongside other contingent claims models.  相似文献

To explain the persistence of dominant New York Stock Exchange (NYSE) market share in stock trading of listed securities from 1992 to 2002, we develop a dominant‐firm price leadership model and hypothesize that NYSE specialists raised the costs of rival market makers. The model predicts that natural and induced cost advantages will determine the NYSE's market share vis‐à‐vis the regional exchanges, electronic trading systems, and NASDAQ dealers. Empirically, NYSE market share increases with economies of scale and scope, abnormal price volatility, high asymmetric information, and with trading practices that raise rivals' costs, such as failure to display limit orders that bettered the existing quotes.  相似文献

World-wide cross-country regressions are used to examine South Asia's export structure through the lens of Heckscher‐Ohlin trade theory. By comparison with other regions, South Asia's exports are unusually concentrated on labour-intensive manufactures. This distinctive export structure is shown to be the result mainly of South Asia's distinctive combination of resources: by comparison with other regions, it has a low level of education and few natural resources, relative to its supply of labour. This basic economic fact must be recognized in the design of trade and development strategy for South Asia over the next few decades.  相似文献

The leisure research?leisure practice relation remains uncertain. Assuming leisure provides a preexisting link is not supported by research. Leisure research and leisure practice are independent professional paradigms between which a relation must be constructed. Three perspectives on constructing the research?practice relation are examined in this article: the traditional, the personal, and the critical. The benefits approach to leisure is a test case in each perspective. The traditional and personal perspectives subordinate one professional paradigm to the other or intensify their separation. The benefits approach fails to resolve these difficulties. The critical perspective emphasizes developmental activity and emancipation, facilitates research?practice interaction, and maintains the professional paradigms' integrity, and it reveals shortcomings in the benefits approach. The critical perspective enables the most dynamic research?practice relation.  相似文献

Recent research suggests that managers often make strategic decisions in novel situations by utilizing past experiences to reason by analogy. However, there is substantial evidence that decision makers often fail to identify and apply knowledge about one situation to a similarly structured situation. Two experimental studies investigated the mechanisms impacting knowledge transfer from one managerial situation (the source) to an analogous situation. The results show that exposure to variation in the source situation improves transfer performance. Variation decreases performance in the short term but improves learning and increases analogical transfer. Higher performance on and systematic search of the source situation also increase transfer performance. These results yield important implications for enhancing analogical transfer in strategic decision making and for future research on reasoning by analogy.

Abstract . It is the purpose of this paper to examine critically the choice of “zero discharge” as me ultimate goal of our federal water pollution policy and to demonstrate that a goal of 90 percent removal of pollutants from effluents of urban areas will be more economically efficient. Our results indicate that in reaching “Zero discharge,” there is a minimal return in water quality for urban areas which are located on large bodies of water. The final conclusion is that the substantial resources, which would be required to surpass the level of 90 percent removal of pollutants, could be employed more effectively in other social programs.  相似文献
