Regulatory reform of the UK gas market: The sase of the storage auction

The UK gas industry has undergone major changes since it was privatised in 1986 as a fully integrated monopoly. The most significant of these has occurred not as a result of the privatisation legislation but by the intervention of the ordinary competition authorities in support of an active industry regulator. While price capping continues to be used as the primary instrument for welfare protection against the still substantial monopolistic powers of the incumbent, new competition (which has been positively encouraged) has had the greater impact on prices and choice. Recently, however, the regulator has encouraged the use of auctions for the sale of storage capacity. This paper considers the merits of auctions and makes a tentative evaluation of their effectiveness. Further use of auctions is recommended but reserve prices are considered inappropriate where monopoly power still remains.     

Strategic Certification and Provision of Quality

We study the effect of the presence of a certification intermediary in an environment where information asymmetries are particularly severe. The intermediary improves the information that buyers have about quality. This in turn increases the incentives that the seller has to provide high-quality goods. Efficiency is increased by the presence of the intermediary, but quality is underprovided in equilibrium relative to full information. The intermediary can implement the optimal policy in many ways. The amount of information revealed ranges from full disclosure to partial, noisy disclosure.     

Multi-attribute Auction and Negotiation for e-Procurement of Logistics

The paper addresses the topic of e-procurement of logistics services and examines how the system that companies adopt to support this task affects the process performance. The system is evaluated in terms of substantive outcomes (e.g., logistics providers’ profits) and other performances related to perceptions and behavioral issues. Specifically, the considered system is characterized by the exchange mechanism that rules the transaction (multi-attribute auction vs. negotiation) and the level of problem complexity. The analysis, conducted via a laboratory experiment, shows that both the exchange mechanism and the problem complexity affect performance. Practical implications, which could help companies design effective e-procurement systems, are discussed.     

An examination of the ethical beliefs of managers using selected scenarios in a cross-cultural environment

Academic literature addressing the topic of business ethics has paid little attention to cross-cultural studies of business ethics. Uncertainty exists concerning the effect of culture on ethical beliefs. The purpose of this research is to compare the ethical beliefs of managers operating in South Africa and Australia. Responses of 52 managers to a series of ethical scenarios were sought. Results indicate that despite differences in socio-cultural and political factors there are no statistically significant differences between the two groups regarding their own ethical beliefs. Results thus support the view that culture has little or no impact on ethical beliefs.Russell Abratt (DBA Pretoria) is Professor of Marketing at the University of Witwatersrand, Johannesburg, South Africa.

Shaping buyer–supplier relationships in manufacturing contexts: Design and test of a contingency model

Although the idea that buyer–supplier partnerships can yield considerable benefits to firms is largely diffused among researchers and practitioners, the approach adopted in this paper is that no “one best way” exists in buyer–supplier relationships, but rather a “best way” for each specific exchange context. Hence, this paper proposes a contingency model for shaping and managing buyer–supplier relationships in manufacturing contexts. In order to test the model, an empirical study was performed on a sample of 45 buyer–supplier relationships within the Italian white goods industry. A three-dimensional performance indicator was computed to compare supplier performance achieved within relations matching the model's suggestions with those set differently. The results strongly suggest that suppliers involved in relationships set accordingly to the contingency model are likely to enjoy superior performance.     

ON THE EMERGENCE OF TOYBOYS: THE TIMING OF MARRIAGE WITH AGING AND UNCERTAIN CAREERS*

We explore how gender bias in career opportunities affects matching in a marriage market with search frictions and where an individual’s fitness decays with age. We document a “being left on the shelf” effect where young singles, who find the marriage market rapidly thins with age, rush into early partnership. Singles with stronger career opportunities, however, have a greater option value to defer marriage. More equal career opportunities for women (captured by greater schooling and better occupations) potentially explain the recent emergence of toyboy unions, in which the woman is at least 5 years older than her partner.     

The Role of Professional Codes in Regarding Ethical Conduct

This paper investigates the regulation of ethical behavior of professionals. Ethical perceptions of South African professionals operating in the business community (specifically accountants, lawyers and engineers) concerning their need for and awareness of professional codes, and the frequency and acceptability of peer contravention of such codes were sought. The existence of conflict between corporate codes and professional codes was also investigated. Results, based on 217 replies, indicated that the professionals believe that codes are necessary and are relatively aware of the contents of such codes. Despite these ethical tendencies, respondents (particularly lawyers) believe that their peers contravene their professional codes relatively often. No significant differences in ethical tendencies between professionals consulting to and those working in business were found. Many respondents were regulated by more than one code of ethics, but few experienced conflict between such codes. In the events of conflict occurring professionals chose to adhere to their professional code above others.     

Responsible Leadership: Pathways to the Future

After defining the essential elements of Aristotelian citizenship, the article proposes to apply these criteria in its search for the equivalent of a citizen within the corporate polis. It argues that shareholding managers are the best positioned among a firm’s constituents or stakeholders in fulfilling the role of corporate citizens. Greater participation by management not only in the control but also in the ownership of firms brings about benefits for the firm as a whole and for the managers themselves, as organizational citizenship behavior literature, among others, suggests.     

Evolution and challenges of dairy supply chains: Evidence from supermarkets,industries and consumers in Ethiopia

In developing countries the demand for products of animal origin is expected to grow rapidly in the coming years. Using data collected from 200 urban households this study examines the evolution of the dairy market in Ethiopia. In particular, this study suggests that although the Ethiopian dairy market remains extremely thin and volatile, the commercialization of processed dairy products through supermarkets is expanding and is expected to keep doing so in the foreseeable future. Increasing urbanization and corresponding changes in consumer preferences, behaviour and purchasing power are the identified causes for the rise of supermarket-processor dairy chains. This study shows also that emerging dairy chains provide new market opportunities to Ethiopian farmers, but the existence of retail-industrial monopolies and monopsonies jeopardize farmers’ economic benefits to a great extent. The study concludes with some implications for policy and further research.
