This paper empirically examines herding behavior in the strategic style allocations of Spanish pension plan managers. The study uses both the standard metric used in financial literature to capture institutional herding and a new approach to address some shortcomings of this traditional measure. Concretely, some authors have highlighted that the traditional measure does not take into account that the probability that a manager buys rather than sells a certain stock depends on both the initial holding in the stock and the asset flows. As a consequence, this study proposes a new approach, which can be applied to other financial markets and provides more accurate values of the probability to increase (or decrease) the style exposures bearing in mind the previous exposure of each portfolio. The study confirms the existence of herding behavior by using both methods. Although the strength of this behavior decreases using the new approach, the herding levels detected in this study of style herding of Spanish pension plans are higher than those of previous research analyzing portfolio holdings in other countries. Additionally, herding levels are higher in periods of low volatility while market returns does not seem to influence herding levels.  相似文献

This article focuses on a recent concept of covariation for processes taking values in a separable Banach space $B$ and a corresponding quadratic variation. The latter is more general than the classical one of Métivier and Pellaumail. Those notions are associated with some subspace $\chi $ of the dual of the projective tensor product of $B$ with itself. We also introduce the notion of a convolution type process, which is a natural generalization of the Itô process and the concept of $\bar{\nu }_0$ -semimartingale, which is a natural extension of the classical notion of semimartingale. The framework is the stochastic calculus via regularization in Banach spaces. Two main applications are mentioned: one related to Clark–Ocone formula for finite quadratic variation processes; the second one concerns the probabilistic representation of a Hilbert valued partial differential equation of Kolmogorov type.  相似文献

This paper introduces and tests Bid Function Equilibria (BFE) in the British spot market for electricity. BFE extend von der Fehr and Harbord's (1993) multi-unit auction model of wholesale electricity markets by allowing firms to have heterogeneous costs for different generating units. Pure-strategy equilibria in BFE predict asymmetric bidding by producers: a single firm (the “price-setter") bids strategically while other firms (“non-price-setters") bid their costs. We test for asymmetries in firms' bid functions in the British spot market between 1993 and 1995 and find strong empirical support for the theory. We conclude that BFE have important implications for the design and governance of electricity markets.  相似文献

The diversity of approaches to customer relationship management (CRM) brings about the need for systematic reviews. The objective of this article is to identify and categorize the most used publications in the CRM field. We conducted a bibliometric analysis using the Web of Science database. To identify and categorize the subfields, we conducted an exploratory factor analysis. The most used publications were categorized into: (1) methodology in the CRM research field; (2) relationship marketing; (3) service quality and customer loyalty; (4) implications of market-oriented strategy; (5) CRM theory and its practical implications; (6) strategic management; and (7) customer value.  相似文献

Studies have shown that exposure to sponsorship can influence behavior. However, evidence of the effectiveness of sports advertising and its influence on alcohol consumption is inconclusive. The goal of this research is to examine whether sponsorship by alcohol products receives the same attention as sponsorship by nonalcohol products depending on their congruence and the way they influence the intention to consume. Using sports posters, an experiment was performed to measure attention through eye-tracking. The results show that attention paid to alcohol brands is no greater than the attention paid to incongruent brands and is no different from the attention paid to congruent brands, regardless of gender and sporting discipline. Attention paid to sponsors has no influence on the intention to consume. These results show the need for further research on the effectiveness of sponsorship and its relationship with alcohol consumption.  相似文献

The main goal of this paper is to evaluate the possibility of finding international consumer segments in the organic food product (OFP) market. For that purpose, the power of country of residence in discriminating between urban frequent, occasional and non‐consumers of OFP was evaluated; and the most appropriate international segmentation bases for that market were studied. In order to achieve this goal, a survey of organic food consumers from Lisbon (Portuguese) and Berlin (German) was implemented through a structured questionnaire. Upon this, factorial and discriminant analysis was applied to the data. The results highlight the significance of the “Country” variable when distinguishing between groups of urban OFP consumers and non‐consumers as well as between frequent and occasional urban OFP consumers. The different levels of OFP consumption are mostly explained by the level of declared “OFP knowledge”. Therefore, we can conclude that in order to increase the consumption of OFP and dilute the effect of the country variable and to be able to work with international segments, marketers should aim to increase awareness and knowledge on these products. It is important to mention that this study was based on a non‐probabilistic sample and, consequently, generalizations of its conclusions must be made with care.  相似文献

Scholars in the fields of organization and strategic communication have long been interested in organizational identification as a phenomenon favoring employees’ alignment with corporate values and consequently achievement of the organizational mission. To date, most studies on the subject have relied on social identity theory, which focuses on cognitive categorization processes but overlooks the role of employees’ relationships within their organization. In this research, we introduce a social capital perspective into organizational identification models. We propose and test a model looking at the influence of an individual’s social capital, a variable deriving from different dimensions of an individual’s communication network (i.e., prestige, resourceful others, friendship), on organizational identification, mediated by the attractiveness of perceived organizational identity. The results from a survey conducted in a business organization suggest that a person’s social capital influences organizational identification, both directly and through the attractiveness of perceived organizational identity. Our organizational identification model contributes to extend knowledge on the complementarity of the cognitive and relational perspectives of strategic communication and on the role of relationship building and networks in strategic communication management.  相似文献

In this study, we examine the cross‐cultural differences in human resource (HR) managers’ beliefs in effective HR practices by surveying HR practitioners in Finland (N = 86), South Korea (N = 147), and Spain (N = 196). Similar to previous studies from the United States, the Netherlands, and Australia, there are large discrepancies between HR practitioner beliefs and research findings, particularly in the area of staffing. In addition, we find that interpersonal‐oriented aspects of HR practices tend to be more culturally bound than technical‐oriented aspects of HR practices. We interpret the differences using Hofstede's cultural dimensions (Power Distance, Individualism versus Collectivism, Masculinity versus Femininity, Long‐Term Orientation versus Short‐Term Orientation, and Uncertainty Avoidance). We discuss the overall nature of the science‐practice gap in HR management, and the implications for evidence‐based management. © 2014 Wiley Periodicals, Inc.  相似文献
