How the Netherlands became a bicycle nation: Users,firms and intermediaries, 1860–1940

In 1925, the Netherlands was a country of cyclists and cycle producers, as all classes cycled and almost all cycles were produced domestically. The bicycle was not a Dutch invention and the country had an open economy, and this raises the question ‘how did the Netherlands become a bicycle nation?’ This article investigates the interactions of users, firms and intermediaries from 1860 to 1940 and how these impacted the bicycle, its production and its use. Furthermore, it analyses knowledge flows and the roles of intermediaries. It illustrates changes in activities and the relevance of interactions between users, firms and intermediaries, and the effects of World War I. It shows how user organisations created an infrastructure and culture which made cycling Dutch. Firms created a cartel which produced bicycles that were wanted and used by all Dutch, as they were made in the Netherlands.     

Price and Quality Strategies for Services:

Developing effective price and service quality strategies requires an understanding of the effect of price and service quality on buyers' attitudes, intentions and purchase decisions. Consumer Involvement is an important variable that may interact with price and service quality, and is the focus of this research. This paper examines the influence of involvement, price and service quality on attitudes and intention to purchase automobile insurance and long-distance telephone services.     

Organics: marketplace icon

This essay explores and debates the status of organics as a marketplace icon. Organic products are somewhat unique in having a place in both mainstream and niche markets. The breadth of organic products and sales continue to rise, and certification processes have become more sophisticated, stringent and successful. Organics are loved and loathed by consumers, and loved and loathed (and often parodied) in popular culture. The market is both friend and enemy of organic products and organic consumers. What organics mean is complicated and confusing, and their benefits for both the natural environment and human health are contested. Scrutiny of organics allows us to explore how the relationship between regulations, the market and popular culture contribute to the development of an icon, firmly rooted in the marketplace, while also maintaining its status as ambivalent commodity. I conclude that organics are indeed marketplace icons – but decline to offer advice on whether or not I recommend becoming an organic consumer (despite my own avid purchase of all things organic).     

Strengthening Globalization’s Invisible Hand: What Matters Most?

In this paper, we investigate what matters most to sustaining strong economic growth in today’s more globalized, knowledge economy. An examination of 2005- 2006 statistical and survey data across 52 countries reveals that economic growth is driven mainly by developed and trustworthy financial markets, a well-educated and skilled workforce, and access to information and communications technologies. Moreover, we find that creditworthy financial markets are strengthened by free and open economies based on the rule of law and legal protections. Our findings support the notion that innovative ideas and entrepreneurship are at the heart of economic growth. However, these ideas need support from institutional policies and practices that create and sustain growth by providing needed protections and a market in which to finance them.

Knowledge and training in family firms of the European periphery: Spain in the eighteenth to twentieth centuries

This article is a first attempt to explore the relationship between training and entrepreneurship in Spanish family firms. It examines changes and continuities over time, and relates the evolution of the training practices of Spanish family firms to the technical and economic conditions of the first and second industrial revolutions. The article demonstrates the interaction betweeen technical and educational ideas, the creative adaptation to the entrepreneurial needs of regions and economic sectors, and institutional conditions. It is organised in three main sections. The first briefly introduces new institutional and sociological theories applied to the study of the formation of business groups. The second summarises existing literature and research that deals with knowledge transference and business training in Spanish family firms, and provides a general survey of informal and formal business education in eighteenth to twentieth-century Spain. The third presents case studies of changing training practices in big and old family firms, and relates this evidence with theoretical and institutional insights.     

Mapping symbolic (anti-) consumption

Rejection is at the heart of anti-consumption and is therefore key to some of the central relationships in symbolic consumption. However, researchers find rejection difficult to study because of the lack of material traces. This article draws on earlier frameworks to develop a new integrated and expanded conceptualization in order to achieve a more nuanced view of how rejection operates within symbolic consumption; and also to initiate research directions for investigating and theorizing rejection in anti-consumption. The focus on anti-consumption incorporates the interaction between avoidance, aversion and abandonment, and the relationship between distastes and the undesired self (mediated by the marketing, social and individual environments). A series of interrelationships and illustrations suggest how the expanded conceptualization is useful for theorizing and investigating anti-consumption.     

Striking a Balance Between Rules and Principles-based Approaches for Effective Governance: A Risks-based Approach

Several recent studies and initiatives have emphasized the importance of a strong ethical organizational DNA (ODNA) to create and promote an effective corporate governance culture of trust, integrity and intellectual honesty. This paper highlights the drawbacks of an excessively heavy reliance on rules-based approaches that increase the cost of doing business, overshadow essential elements of good corporate governance, create a culture of dependency, and can result in legal absolutism. The paper makes the case that the way forward for effective corporate governance is to strike an optimal balance between rules-based and principles-based approaches. The recent corporate scandals have demonstrated that the ethical ODNA is critical to the driving force and basis of legal and regulatory requirements. Effective governance means adhering to ethical principles, not merely complying with rules, and is a crucial guardian of a firm’s reputation and integrity. It is through an effective corporate governance program (that is, one that optimally captures and integrates the appropriate aspects of rules-based and principles-based approaches, and identifies and assesses the related risks) that an organization can reconfigure its ODNA for improved performance. Focusing on the ethical ODNA as the basis of new governance measures provides an opportunity to develop a competitive advantage as it represents a potential source of differentiation, strengthens the relationship with all stakeholders of the organization by building a culture of trust and integrity, and re-instills investor confidence. This paper employs dialectical reasoning that links the ODNA through principles-driven rules in developing a risks-based approach. A comparison from a risk assessment perspective between rules-based and principles-based approaches is presented. Although there have been few applications employing dialectical reasoning in business research, this methodology can be extremely useful in isolating ethical issues and integrating them into the business process. The risks-based approach captures the benefits of both rules-based and principles-based approaches, and incorporates trust-based principles such␣as solidarity, subsidiarity and covenantal relationships.Sundera Arjoon is a Senior Lecturer in Ethics at the Department of Management Studies, The University of the West Indies, Trinidad, He has served as Head of Department (2002–2005) and as Deputy Dean of the Faculty of Social Sciences (1996–2002).

Factors Associated with Opinion Seeking

Abstract

This study examines the relationship between opinion seeking and cultural values and individual characteristics in the context of electronic products by surveying cosmopolitan adults of 15 nationalities, namely, American, Australian, British, Dutch, Filipino, German, Hong Konger, Indian, Italian, Japanese, Malaysian, New Zealander, Singaporean, Swedish, and Thai. It finds (i) positive correlation between opinion seeking and power distance, category knowledge, category purchase intention, category innovativeness, opinion giving, market maven, brand loyalty, and susceptibility to interpersonal influence, (ii) negative correlation between opinion seeking and the masculinity and uncertainty avoidance cultural dimensions, category ownership, self-esteem, education, and age, and (iii) no correlation between opinion seeking and individualism, long-term orientation, and risk taking. It then discusses the managerial implications of the findings.     

Traditional Sushi for Modern Consumers: A Comparison Between Sushi Consumption Behavior in Japan and Norway

This study focused on differences between uses and users of sushi and sashimi in Norway and Japan. The study was based on a consumer survey that was completed by a representative sample of 902 participants from Norway and 897 participants from Japan. The survey included questions about food consumption frequency, ways of sourcing sushi and sashimi and situational factors related to consumption. Participants also reported their knowledge about, attitudes toward, and ambivalence related to sushi and sashimi, social acceptability of sushi and sashimi consumption, domain-specific innovativeness, and social and demographic characteristics. Differences in sushi consumption behavior between Japanese and Norwegian consumers considering the situational parameters surrounding sushi and sashimi consumption were revealed. Considerations for future research and implications on export strategy development were discussed.
