Polynomial goal programming and the implicit higher moment preferences of US institutional investors in hedge funds

Polynomial goal programming (PGP) is a flexible method that allows investor preferences for different moments of the return distribution of financial assets to be included in the portfolio optimization. The method is intuitive and particularly suitable for incorporating investor preferences in higher moments of the return distribution. However, until now, PGP has not been able to meet its full potential because it requires quantification of “real” preference parameters towards those moments. To date, the chosen preference parameters have been selected somewhat “arbitrarily”. Our goal is to calculate implied sets of preference parameters using investors’ choices of and the importance they attribute to risk and performance measures. We use three groups of institutional investors—pension funds, insurance companies, and endowments—and derive implied sets of preference parameters in the context of a hedge fund portfolio optimization. To determine “real” preferences for the higher moments of the portfolio return distribution, we first fit implied preference parameters so that the PGP optimal portfolio is identical to the desired hedge fund portfolio. With the obtained economically justified sets of preference parameters, the well-established PGP framework can be employed more efficiently to derive allocations that satisfy institutional investor expectations for hedge fund investments. Furthermore, the implied preference parameters enable fund of hedge fund managers and other investment managers to derive optimal portfolio allocations based on specific investor expectations. Moreover, the importance of individual moments, as well as their marginal rates of substitution, can be assessed.     

Debt covenant renegotiations and creditor control rights

Using a large sample of private debt renegotiations from 1996 to 2011, we report that, even in the absence of any covenant violation, debt covenants are frequently renegotiated. These renegotiations primarily relax existing restrictions and result in economically large changes in existing limits. Renegotiations of specific covenants are a response to both the distance the covenant variable is from its contractual limit and the firm?s specific operating conditions and prospects. Moreover, the borrower?s post-renegotiation investment and financial policies are strongly associated with the covenant changes resulting from the renegotiation. Overall, the findings imply that, even outside of default states, creditors have strong control rights over the borrower?s operating and financial policies, and they exercise these rights in a state contingent manner through covenant renegotiations.     

Union Representatives in Labour–Management Partnerships: Roles and Identities in Flux

This study examines the challenges met by union representatives (URs) who have to reconstruct their traditional role in the context of labour–management partnerships. They are innovators involved in the transition to renewed labour relations. Identity issues and role conflicts are examined through an in‐depth analysis of the process involved in assimilating this new role in unionized organizations. The results suggest that URs subordinate the partner role to the interest representation role. Interviews suggest that this enhanced union legitimacy. Some blurring of traditional social categories such as those of employee or employer is possible to the extent that the relations between the actors are founded on interpersonal relations.     

FTA and equity: New approaches to governance

FTA and equity addresses the need for multiple stakeholders’ participation in public policy and corporate decision making thus leading to more democratic societies. The need for more participative and inclusive decision making is due to the move from the technocratic nature of decision making towards more democratic processes, which is a result of the transformation of societies and situations as a result of various factors including globalisation, environmental concerns, more knowledge intensive work and lifestyle.The current paper addresses Future-oriented Technology Analyses (FTA) in the context of a better understanding of issues that ought to be considered by the FTA community so that it can support the quest for new forms of governance. The paper has been structured on the discussion of governance around three pillars: socio-cultural evolution, corporate industrial activity and government.Analysis of the relationship between governance and each of the three pillars poses a number of questions to the FTA community that reflect on the potential impacts of FTA activities in governance. Setting a new landscape for the FTA, the paper concludes with those issues where the FTA community is starting to devote attention, as well as those it still ought to consider.     

Pricing Bermudan options by nonparametric regression: optimal rates of convergence for lower estimates

The problem of pricing Bermudan options using simulations and nonparametric regression is considered. We derive optimal nonasymptotic bounds for the low biased estimate based on a suboptimal stopping rule constructed from some estimates of the optimal continuation values. These estimates may be of different nature, local or global, with the only requirement being that the deviations of these estimates from the true continuation values can be uniformly bounded in probability. As an illustration, we discuss a class of local polynomial estimates which, under some regularity conditions, yield continuation values estimates possessing the required property.     

Measuring entrepreneurial passion: Conceptual foundations and scale validation

Along with other affective and emotional dimensions, passion is at the heart of entrepreneurship. Yet past research on entrepreneurial passion (EP) has been hindered by the lack of a sound measurement instrument. Through a series of empirical studies conducted with samples from relevant populations, we develop and validate an instrument to capture EP and its inherent dimensions. We show that the task-specific dimensions of EP (intense positive feelings toward the domains of inventing, founding and developing, and the centrality of these domains to entrepreneurs' self-identity) are conceptually and empirically distinct from one another, and from other emotions and cognitions known to play a role in entrepreneurship. Our theory and results indicate that proper measurement of entrepreneurial passion incorporates the interaction between entrepreneurs' feelings and identity centrality for each domain. We discuss the implications of our model, instrument and findings for future research on the affective components of innovation and entrepreneurship. We also develop specific guidelines for using our validated instrument in future research.     

The creation of complicity a semiotic analysis of an advertising campaign for Black & White whisky

A qualitative pre-test study, employing the structured semiotic methodology of Greimas and the Paris school, was conducted on four print advertisements conceived for a Black & White whisky campaign, and this article presents the major findings. Both the content and expression of the advertisements are examined, in terms of elementary oppositions, of narrative organization, of cultural values, and of linguistic and plastic manifestations. Finally, the ironic quality of the enunciation, playing on cultural stereotypes, is shown to demonstrate an equivalence between the ‘author’ of the campaign and the target public envisaged.     

Judgemental Overconfidence, Self-Monitoring, and Trading Performance in an Experimental Financial Market

We measure the degree of overconfidence in judgement (in the form of miscalibration, i.e. the tendency to overestimate the precision of one's information) and self-monitoring (a form of attentiveness to social cues) of 245 participants and also observe their behaviour in an experimental financial market under asymmetric information. Miscalibrated traders, underestimating the conditional uncertainty about the asset value, are expected to be especially vulnerable to the winner's curse. High self-monitors are expected to behave strategically and achieve superior results. Our empirical results show that miscalibration reduces and self-monitoring enhances trading performance. The effect of the psychological variables is strong for men but non-existent for women.     

An engineering approach to LSE modelling of experience curves in the electricity supply industry

This review is a supplement to the paper by Sharp and Price (1990) and should be regarded as an alternative engineering approach to the modelling and forecasting of experience, or learning, curves. It highlights the problems associated with accurately defining a model to time series that show a combination of a continuous trend and a cyclical component, as detected by the authors in the Sharp and Price data. The authors give a number of alternative perspectives of the same time series, in this case average thermal efficiency data from the U.K. electricity supply industry, with the corresponding conclusions associated with each approach. Particular attention is drawn to the use of the “time constant learning curve” quoted by Sharp and Price which the authors show is a reasonable predictor of the average thermal efficiency. However, a tremendous improvement results from selecting the “ripple” model as a thermal efficiency predictor.
