Efficiency evaluation of Greek equity funds

This study assesses the relative performance of Greek equity funds employing a non-parametric method, namely Data Envelopment Analysis (DEA). Specifically, we evaluate the funds’ total productivity change using the DEA-based Malmquist Index. Our results reveal significant losses in funds’ productivity for the period of 2003–2009, which calls for the attention of domestic policy makers and market regulators. Significant implications for the investors’ fund selection process arise from our analysis since we are able to identify potential sources of operational inefficiencies. Employing a panel logit model we document a significant negative relationship between the probability of being efficient and funds’ size, a finding which may be related to the microstructure of the domestic stock market. Furthermore, we provide evidence against the notion of funds’ mean-variance efficiency.     

The Theory of Planned Behavior in the Context of a Food and Drink Event: A Case Study

The present case study seeks to contribute to the culinary event management literature, investigating key motivators among participants to the Derbyshire Food and Drink Fair, United Kingdom. A questionnaire, which was partly based on predictors related to the theory of planned behavior was designed and distributed; 308 usable responses were collected. The validity and impact of attitude toward the behavior, perceived behavioral control, and subjective norms on behavioral intention was confirmed. Additionally, several motivators, such as “commitment and perceived importance,” “consumption and entertainment,” “attendance and discovery,” and “joining others” were identified as key factors. Finally, statistically significant differences were noticed among various participating groups, namely, in terms of age, gender, or distance traveled to the event. The findings have important implications for event managers and organizers, in terms of promotion, and addressing the needs and wants of various segments of food festival attendees.     

Institutional characteristics and capital structure: A cross-national comparison

The main objective of this paper is to investigate whether differences in institutional characteristics result in different capital structure determination among countries. First, we analyze the institutional setting in Greece compared with that of other countries. Second, we provide survey information about the determinants of capital structure in Greece and compare our findings with those of similar surveys in the United States and Europe based on Graham and Harvey [Graham, J., & Harvey, C. (2001). The theory and practice of corporate finance: Evidence from the field. Journal of Financial Economics, 60, 187–243], Bancel and Mittoo [Bancel, F., & Mittoo, U. (2004). Cross-country determinants of capital structure choice: A survey of European firms. Financial Management, 33(4), 103–133 Winter 2004] and Brounen, de Jong and Koedijk [Brounen, D., de Jong A., & Koedijk, K. (2006). Capital structure policies in Europe: Survey evidence. Journal of Banking and Finance, 30, 1409–1442] respectively. Greek firms seem to follow an own-business policy and seem to care more about the disadvantages of debt than try to exploit its advantages. Financial distress considerations, market timing and competitiveness are important factors, whereas agency costs of equity, pecking order and the signalling theory do not seem to apply. Conclusions are relatively similar with those of other countries, though specific differences that can be attributed to the different institutional settings do exist. In general however, we conclude that differences in institutional characteristics do not seem to affect the way of thinking of financial managers when they decide on capital structure issues.     

The influence of formal and informal sales controls on customer-directed selling behaviors and sales unit effectiveness

Adaptive selling (AS) and customer-oriented selling (COS) constitute two key customer-directed selling behaviors for the success of the modern sales force. However, knowledge regarding the organizational factors that can induce salespeople to engage in those behaviors is strikingly limited. Against this background, we develop a comprehensive model that delineates the influences of formal and informal sales controls on AS and COS and, through them, on sales unit effectiveness. Based on a sample of sales managers in a major European Union country, we present new evidence that (a) formal and informal sales controls exert differential impact on salespeople's AS and COS behaviors; (b) AS directly and positively influences sales unit effectiveness; (c) COS affects sales unit effectiveness only indirectly, i.e. by fostering AS; and (d) outcome and cultural controls directly improve sales unit effectiveness. We conclude with a discussion of our findings for academics and practitioners.

The role of the workplace in ethnic wage differentials

Using linked employer–employee data for Britain, we examine ethnic wage differentials among full-time employees. We find substantial ethnic segregation across workplaces. However, this inter-workplace segregation does not contribute to the aggregate wage penalty in Britain. Instead, most of the ethnic wage gap exists within the workplace, between observationally-equivalent co-workers. Lower pay satisfaction and higher levels of skill mismatch among ethnic minority workers are consistent with discrimination in wage-setting on the part of employers. The presence of recognized trade unions and the use of job evaluation schemes within the workplace are associated with a smaller ethnic wage gap. These findings indicate that more attention should be placed on ensuring fairness in wage determination.     

An experiment on spatial competition with endogenous pricing

Hotelling's (1929) principle of minimum differentiation and the alternative prediction that firms will maximally differentiate from their rivals in order to relax price competition have not been explicitly tested so far. We report results from experimental spatial duopolies designed to address this issue. The levels of product differentiation observed are systematically lower than predicted in equilibrium under risk neutrality and compatible with risk aversion. The observed prices are consistent with collusion attempts. Our main findings are robust to variations in three experimental conditions: automated vs. human market sharing rule for ties, individual vs. collective decision making, and even vs. odd number of locations.     

Selling and sales management: An introduction to the special section and recommendations on advancing the sales research agenda

Effectively managing the sales function is a prerequisite for success in business markets. Thus, practitioners are increasingly interested in improving the performance of their sales function. However, there is evidence pinpointing that academic research in the area may be experiencing a decline in its status among other subject areas in the marketing discipline. Fortunately, advances in the field of selling and sales management as reflected in the organization of specialized conferences/meetings and the development of special journal issues hold the promise of enhancing the status of sales within marketing academia. Following this stream of activities, this IMM special section on “Selling & Sales Management” aims at stimulating the level of discourse regarding how research in our field can be advanced. The present article introduces the special section; next, it summarizes the articles comprising the special section; and, finally, it concludes with some thoughts on fruitful research opportunities in the sales area.     

Objective methods for graphical structural learning

Graphical models are used for expressing conditional independence relationships among variables by the means of graphs, whose structure is typically unknown and must be inferred by the data at hand. We propose a theoretically sound Objective Bayes procedure for graphical model selection. Our method is based on the Expected-Posterior Prior and on the Power-Expected-Posterior Prior. We use as input of the proposed methodology a default improper prior and suggest computationally efficient approximations of Bayes factors and posterior odds. In a variety of simulated scenarios with varying number of nodes and sample sizes, we show that our method is highly competitive with, or better than, current benchmarks. We also discuss an application to protein-signaling data, which wieldy confirms existing results in the scientific literature.     

The Cinderella moment: Exploring consumers' motivations to engage with renting as collaborative luxury consumption mode

Past literature argued that the purchase of luxury goods is driven by people's motivation to conform or fit into our economic and social system. In this study, the authors focus on a new aspect of consumption, that is, renting instead of purchasing luxury goods, backed by the emerging opportunities of sharing economy platforms. Drawing upon the analysis of spontaneous consumers' online communications (in the form of tweets), this study aims to investigate the motivations to engage with luxury garment renting within a collaborative consumption context. To this end, a series of automatic content analyses, via two studies, were conducted using the tweets posted with respect to the Run the Runway collaborative consumption platform. Results demonstrate consumers' increased willingness to show their social status through renting rather than owning luxurious apparel based on five main motivators (need to wear new clothes for a special event, inspirations created by the products/brands, possibility to explore a new way of consuming luxury goods, need to make more sustainable choices, and to increase the life cycle of each luxury product). The implications of these findings are discussed, while they pave the way for future research in collaborative consumption of luxury retailing.
