The quality of volatility traded on the over‐the‐counter currency market: A multiple horizons study

Previous studies of the quality of market‐forecasted volatility have used the volatility that is implied by exchange‐traded option prices. The use of implied volatility in estimating the market view of future volatility has suffered from variable measurement errors, such as the non‐synchronization of option and underlying asset prices, the expiration‐day effect, and the volatility smile effect. This study circumvents these problems by using the quoted implied volatility from the over‐the‐counter (OTC) currency option market, in which traders quote prices in terms of volatility. Furthermore, the OTC currency options have daily quotes for standard maturities, which allows the study to look at the market's ability to forecast future volatility for different horizons. The study finds that quoted implied volatility subsumes the information content of historically based forecasts at shorter horizons, and the former is as good as the latter at longer horizons. These results are consistent with the argument that measurement errors have a substantial effect on the implied volatility estimator and the quality of the inferences that are based on it. © 2003 Wiley Periodicals, Inc.

Domestic or Imported Beer Brands? Analysis and Assessment of Brand Equity in the Spanish Market

The Spanish brewing industry is a main economic sector and a major activity in the agrifood area; however, there are few studies regarding the analysis of brand equity in this product. This study aims to analyze brand equity for both a domestic beer brand—Estrella Galicia—and an imported beer brand—Carlsberg. For this purpose a quantitative study is carried out among consumers in order to assess the sources or dimensions of brand equity and its consequences, comparing the 2 brands present in the Spanish market. Results obtained suggest a better evaluation of the domestic brand and reveal that brand loyalty and perceived quality are the dimensions with a higher relevance in beer brand equity.     

What do we [not] know about technology entrepreneurship research?

This study aims to review what we do (and do not) know about technology entrepreneurship (TE) research to date. Based on a categorized bibliometric analysis resulting from a systematic review of 135 scientific articles published in refereed journals over the past 27 years (1986–2013), we identify the core domains of TE, its intellectual structure, the scientific journals with a major impact in this field of research, and the affiliation and collaboration networks within it. Specifically, through a detailed analysis of article co-citations within the TE area, this study provides co-citation networks of authors, journals, and their respective clusters, revealing their rankings in terms of contributions to the TE literature. This comprehensive analysis can be used to enhance our understanding of TE and support further research in this field.     

Moral Identity as Leverage Point in Teaching Business Ethics

This paper examines whether appealing to learners’ moral identity makes a significant contribution to improving their ethical decision making beyond traditional, rule-based teaching. In response to criticisms leveled at rule-based ethics teaching by alternative approaches, we identify moral identity theory and experiments in moral psychology as useful sources to draw on for the creation of a new, identity-based ethics teaching approach. We develop and apply a set of regular self-reflection focused writing tasks added to the traditional teaching program over a one-semester period, and assess the outcomes of an overall sample of 149 postgraduate business school students, who were randomly assigned to one of three conditions: exposure to both identity-based tasks and rule-based teaching, exposure to rule-based teaching only, and the control condition (i.e., no exposure to ethics teaching). Our findings show that, while the three groups reported the same level of ethical decision making at the beginning of the semester, at the end of the semester the students who were exposed to both identity-based and rule-based teaching reported higher level of ethical decision making compared to those who were only exposed to rule-based education. In addition, the students who received rule-based teaching reported higher ethical decision making compared to those in the control condition. These results suggest that a teaching approach which appeals to the learner’s moral identity can act as an effective leverage point when complementing rule-based teaching. This simple approach should be widely adopted as common practice in graduate business schools.     

Appropriating the value from innovation: inimitability and the effectiveness of isolating mechanisms

Preventing the imitation of products and their underlying characteristics is a key source of competitive advantage. Isolating mechanisms, such as patents, brand name and speed to market, render an organisation's inventions imperfectly imitable by competitors, helping sustain the above‐normal returns achieved from a new product innovation. A theoretical framework is developed whereby the characteristics of isolating mechanisms, namely causal ambiguity, asset stock effects and enforceability of property rights, are shown to be important determinants of appropriation effectiveness. A multiple method research design, consisting of a survey of 238 large Australian organisations, and a further six case study organisations, is adopted. The results indicate that isolating mechanisms in the form of technological capabilities, market‐based assets and knowledge protection positively moderate an organisation's returns from their innovation activities, while being first‐to‐market is found to negatively moderate the business returns achieved. Implications for managers in increasing the effectiveness of their appropriation regime, and future directions for research are proposed.     

Does family employment enhance MSEs performance?: Integrating socioemotional wealth and family embeddedness perspectives

This paper analyzes the effect of family employment on performance in micro and small enterprises (MSEs) by combining two research perspectives that, until now, have been conducted separately: the family embeddedness perspective of entrepreneurship (Aldrich and Cliff, 2003) and the socioemotional wealth (SEW) approach to family business (Gomez-Mejia et al 2007). Our integrated perspective allows us to highlight how the nature of the employment relationships in MSEs enhances the benefits derived from the socioemotional endowment associated with family labor, and reduces the opportunity costs of employing relatives. Moreover, we assert that this relationship is moderated by specific family characteristics that determine the firm's ability to preserve the SEW, while at the same time pursuing financial goals. Our results provide partial support to the enhancing role of family labour on MSEs performance: employing family members increases sales but decreases profitability as measured by ROA. This effect also results in improved performance for women-led firms and for firms that have received family funding, but impairs MSEs performance when the business is the main source of the owner´s household income.     

Omnichannel Shopper Segmentation in the Fashion Industry

The purpose of this paper is twofold: first, to identify groups of omnishoppers based on their main motivations (usefulness, enjoyment, and social influence); and, second, to characterize the omnishopper clusters. To this end, we surveyed a sample of 628 customers of an omnichannel clothing store and analyzed the data using cluster analysis. The results reveal three different segments: reluctant omnishoppers, omnichannel enthusiasts, and indifferent omnishoppers; and significant differences in gender, age, income level, and omnichannel behavior among these segments. In contrast, we found no differences in the use of channels and devices. These results have theoretical and managerial implications.     

The competitive nature of the Arab Middle Eastern banking markets

The competitive nature of the Arab Middle Eastern (AME) banking markets during the 1990s is the focus subject of this study. Using banks data from nine AME countries, and utilizing the so-called Rosse-Panzar test to quantitatively appraise the dominant competitive conditions in these markets between 1993–97, this study concluded that banking markets have been operating in the region under conditions of monopolistic competition. An important finding revealed by this study is that in the AME region, where two distinct economic spectrums dominate the markets, banking sector in the oil-producing countries (Gulf States) appears to be less competitive than its counterpart in non-oil countries.
