A SURVEY ON THE FOUR FAMILIES OF PERFORMANCE MEASURES

Performance measurement is one of the most studied subjects in financial literature. Since the introduction of the Sharpe ratio in 1966, a large variety of new measures has appeared constantly in scientific journals as well as in practitioners' publications. The most complete and significant studies of performance measures, so far, have been written by Aftalion and Poncet, Le Sourd, Bacon, and Cogneau and H übner. A review of the most recent literature led us to collect several dozen measures that we classify into four families. We first present the class of relative measures, starting with the Sharpe ratio. Secondly, we analyse absolute measures, beginning with the most famous one ‐ the Jensen alpha. Thirdly, we study general measures based on specific features of the return distribution, where the pioneering contributions are those of Bernardo and Ledoit, and Keating and Shadwick. Finally, the fourth set concerns a few measures that explicitly take into account the investor's utility functions.     

Social Capital Accumulation and the Exercise of Power: The Case of P2 in Italy

This article addresses the production of legitimate forms of power in our democracies by framing the rise and fall of “Propaganda 2” (P2) — a masonic lodge active in Italy during the 1970s — in the analysis of social capital proposed by Pierre Bourdieu. This lens emphasizes the role played by networks in the accumulation of symbolic capital and their interaction with the historical and institutional context in the exercise of symbolic violence. The experience of P2 is then analyzed to describe, on one hand, the characteristics of the networks that are critical to its success and, on the other, the lodge’s capacity to interfere with the economic and political systems within the context of the Cold War in Italy. The willingness to control and provoke institutional change expressed by P2’s affiliates also shows to what extent the accumulation of social capital, in combination with other forms of capital, may represent a threat to public welfare. By illustrating the interaction between networks and the normative framework underlying our institutions, this case study suggests that the experience of P2 is not an exception in the functioning of our democracies.     

How Do Financial Constraints Affect Creativity?

This paper investigates the effects of financial constraints on the outcome of different types of creative tasks such as product ideation and product repair. Four experimental studies examine the effect of financial constraints on creativity of the outcome of a product ideation task, and compare the effect of financial constraints with the effect of another type of constraint (i.e., input restrictions) on creativity of products ideated and on the amount of resources invested in the development of the creative solution. Furthermore, these studies explore the type of creative process ignited by financial constraints and analyze the effect of financial constraints in interaction with an individual difference such as novelty seeking, which embraces more remote determinants of creative performance, on the creativity of the outcomes to a product ideation task, as well as on the creativity of the outcomes to a more constrained task such as repairing an existing product. The results suggest that constrained financial resources may be beneficial to creativity. Financial constraints lead to the ideation of more creative products. Yet these products are generated using fewer inputs and a lower budget than products generated in an unconstrained condition. Furthermore, while yielding outcomes as creative as the ones generated under input constraints, financial constraints induce a parsimonious mindset reflected in the use of less costly resources. More interestingly, financial constraints activate a top‐down rather than a bottom‐up processing strategy in approaching the creative task. Finally, the results show that the effect of financial constraints is stronger for individuals with inherent tendencies toward novelty seeking, because their stock of experiences and perspectives puts them under stress when facing an unconstrained problem space. This interaction effect holds not only for product ideation tasks, but also when the problem space is already constrained in nature, as in the case of repairing a product. These findings, which are quite counterintuitive from the perspective of classic new product development literature, suggest that, at least under certain conditions, the use of financial constraints might constitute a promising approach to foster new ideas' generation, one that leads to more creative outcomes despite using less costly inputs. In addition, our results suggest that, when dealing with a creative task, companies should modulate the adoption of this kind of constraint on the individual characteristics of their employees, specifically on their innate tendency to seek novelty.     

Wendell Bell, the scholar and the human being: His way of looking towards the future

Since his early professional life, Wendell Bell has sought to understand societies in terms of their changes by identifying the connections between sociology and futures studies. His aim, in my view, has been to use his highly developed intellectual capacity to search for indications of alternative futures, and his writings make a crucial contribution to sociology and futures studies and to their necessary interconnections. His efforts are unique in that they are based on the importance of ethical principles to guide human responsibility in present and future societies. His intellectual, professional capacities, as well as his experience, consist in an endeavour to understand the human being as well as its social context. This constant search emerges very clearly from Bell's writings and lectures, as well as from all his human contacts with colleagues, students and friends.     

Does technology make a difference? Evidence from Spanish hotels

Information and communication technologies (ICTs) have positively contributed to the hospitality industry. In Spain, the third tourism destination in the world, hotels have widely adopted computers and the Internet for the internal processes as well as in their relationships with their providers and customers. While some ICT solutions are common in hotels regardless of their category, others may allow to differentiate across upscale hotels and those of inferior level. This study identifies the most discriminating ICT solutions across 3-, 4-, and 5-star hotels, and discusses their potential for improving efficiency and service quality. In particular, digital technology, loyalty programs, and ambient intelligence are some of the most differentiating technologies, which may be implemented by 3- and 4-star hotels to improve the perceived quality of their processes and services.     

A predictability test for a small number of nested models

We introduce quasi-likelihood ratio tests for one sided multivariate hypotheses to evaluate the null that a parsimonious model performs equally well as a small number of models which nest the benchmark. The limiting distributions of the test statistics are non-standard. For critical values we consider: (i) bootstrapping and (ii) simulations assuming normality of the mean square prediction error difference. The proposed tests have good size and power properties compared with existing equal and superior predictive ability tests for multiple model comparison. We apply our tests to study the predictive ability of a Phillips curve type for the US core inflation.     

Who should teach what? Australian perceptions of the roles of universities and practice in the education of professional accountants

This paper addresses the respective roles and responsibilities of universities and practitioners in educating professional accountants. The issues are explored by a review of the literature in accounting and other professions regarding the respective roles of universities and employers in the development of both technical and non-technical knowledge and skills of professionals, particularly accounting practitioners. The literature review suggests that critics of university-based education fail to recognise (a) the changes that have occurred in the roles and responsibilities of accounting practitioners, and (b) the opportunity costs necessarily associated with providing generalist accounting degrees. Universities and employers have comparative advantages for the development of different types of professional skills and knowledge. These insights are extended by way of a series of interviews with Australian accounting practitioners, representatives from professional accounting bodies, recent accounting graduates, and accounting students about their perceptions of the respective responsibilities and roles of universities and employers. Although some interviewees recognised that universities cannot be ‘all things to all people’, there was a tendency to expect universities to have the major responsibility for the development in accounting graduates of both technical and non-technical knowledge and skills. Such perceptions tended to understate the responsibilities and comparative advantage of employers and result in unrealistic expectations about the outcomes of a university education. Employers need to be made more aware of the resource and other limitations associated with university programs and should develop meaningful opportunities for learning and reflection within workplace contexts.
