On syndicate sharing rules for unanimous project rankings

This paper extends the notion of individual certainty equivalent to group certainty equivalent, in order to derive sharing rules that ensure unanimity on project rankings within a syndicate. A constrained maximization problem is set up with optimal project-specific sharing rules as the solution. It is shown that the group certainty equivalent construct allows for experimental derivation of a syndicate's preference function from a procedure parallel to that presently employed for deriving preference functions of individuals. The analysis potentially has a role in examining the nature of optimal compensation systems (sharing rules) for closely held (non-traded) corporations and partnerships.     

Convergence of numerical methods for valuing path-dependent options using interpolation

One method for valuing path-dependent options is the augmented state space approach described in Hull and White (1993) and Barraquand and Pudet (1996), among others. In certain cases, interpolation is required because the number of possible values of the additional state variable grows exponentially. We provide a detailed analysis of the convergence of these algorithms. We show that it is possible for the algorithm to be non-convergent, or to converge to an incorrect answer, if the interpolation scheme is selected in appropriately. We concentrate on Asian options, due to their popularity and because of some errors in the previous literature. This revised version was published online in June 2006 with corrections to the Cover Date.     

The effects of economic news on commodity prices

We assess how commodity prices respond to macroeconomic news and show that commodities have been relatively insensitive to such news over daily frequencies between 1997 and 2009 compared to other financial assets and major exchange rates. Where commodity prices are influenced by news, there is a pro-cyclical bias and these sensitivities have risen as commodities have become increasingly financialized. However, models based on news still do a relatively poor job of forecasting commodity prices at daily frequencies. We also find some asymmetries in how commodity prices respond to news, most notably for gold, which alone among commodities acts as a safe-haven when “bad” economic news emerges.     

RESEARCH AND CONSULTANCY: TOWARDS A CONCEPTUAL SYNTHESIS

This paper describes an investigation into some of the apparent similarities between what certain kinds of researchers and consultants do in organizations. Using a facet analysis approach (Foa, 1965), an instrument was devised with the purpose of identifying and delineating overlaps between organizational research and consultancy. Sixty-six British researchers and consultants took part in the study. The results highlight certain specific similarities and suggest that these may represent aspects of research and consultancy which are crucial to their success. The facets of the two activities which emerged from the study as being common are described by reference to the qualitative data which were generated by participants. A number of important implications for the successful conduct of research and consultancy are discussed with particular reference to the process of managing the relationship between investigators and those with whom they work.     

Advanced models of quality function deployment: a literature review

In this paper, a literature review conducted to study the characteristics of advanced models of quality function deployment (QFD) that have appeared in the literature arena is reported. QFD technique emerged in Japan in the 1970s. QFD has been proving to be a powerful tool that can be used for translating the voice of customers into technical languages. Yet from the beginning of this century, researchers began to point out the need to refine, modify and improve the features of QFD technique. In order to fulfil this need, few researchers brought out several advanced models of QFD. While conducting the literature review reported in this paper, six types of such advanced models of QFD were identified in the literature arena and their characteristics were studied. The result of this study revealed that the procedural and computational complexities are least in the case of an advanced model called total quality function deployment (TQFD). TQFD technique replaces the complex computations involved in applying conventional QFD technique with simple ratings. Besides the formation of teams to translate the voice of customers into work instructions ensures the quick reactions to the customers’ desires in the actual field of implementation. In this background, at end of this paper, it is suggested to adopt TQFD for implementation in traditional organizations in which the prevalence of adequate education for adopting complex procedures is found to be least.     

The generality/specificity issue in consumer innovativeness research

The purpose of the present study was to explore the role of personality in shaping consumer innovativeness by testing a model of the hierarchical relationships between a global (broad or abstract) personality trait, its domain-specific manifestation in a consumer context, and overt consumer behavior. A survey of 465 adult consumers measured global innovativeness, domain-specific innovativeness for two product categories (clothing and electronics) and self-reported purchase of new clothing and electronic items. Three hypotheses were tested. First, global innovativeness is more highly correlated with domain-specific innovativeness than it is with the purchase of new items. Second, domain-specific innovativeness is more highly correlated with the purchase of new items than is global innovativeness. Finally, the association between global innovativeness and new product purchase is mediated by domain-specific innovativeness. All three hypotheses were supported for both product categories.     

Reason rules...: the utility of rationality and the rationality of utility

Almost every theory of human behavior is based upon some assumption of rationalty. Such an assumption is commonly believed to be necessary in order to distinguish rational behavior, which is, from non-rational behavior, which is not amenable to scientific investigation. This article presents a thorough re-examination of this assumption, an inquiry which turns out to raise all the central issues of both the methodology and the theory of behavioral inquiry generally. It leads to the somewhat surprising conclusion that the notion of rationality does not have any meaningful role to play in behavioral inquiry, and that there is no sense in distinguishing rational from non-rational or irrational behavior. It also shows that the generalization of the utility notion in terms of information makes it into a much more powerful and subtle tool of analysis than it commonly appears to be taken for.
