Interpretive structural modeling—A useful tool for technology assessment?

Interpretive Structural Modeling (ISM) is a computer based technique for helping small groups develop graphical representations of complex systems. In this paper, the rationale for the use of Interpretative Structural Modeling in activities such as technology assessment is developed and the basic concepts underlying the technique are explored. Several applications of ISM are described and from these experiences some observations are made about the nature and effectiveness of the ISM process and product. ISM was found to provide its users with a systematic and comprehensive method for integrating group judgments in the development of “first-cut‘ structural models. At the same time, however, the technique was found to be relatively inflexible and may, in some instances, inhibit group processes. Possible directions for the development of less rigid methods are suggested.     

Price leadership in a duopoly with capacity constraints and product differentiation

This paper analyzes Stackelberg price leadership in a duopoly in which firms are capacity constrained and products are imperfect substitutes. Assuming symmetric substitutes, linear demand, and efficient rationing, we characterize the equilibria with an exogenously specified leader. Using the equilibrium profits derived from these games, we argue that over certain ranges of asymmetric capacities an endogenous price leader will emerge. When endogenous leadership does arise, it is the large capacity firm which is the leader. We thus provide a game theoretic model of dominant firm price leadership.Dave Furth's research has been undertaken as a part of the project Competition and Cooperation.

Some characteristics of adopters of a major innovation in the computer field and its potential use in marketing

The computer industry is changing dramatically thanks to new technologies that facilitate departure from the lock-in strategies pursued by the long-term industry leaders. New, highly competent competitors have entered the market with the resulting lower profit margins. Innovations in hardware and software are continuously introduced, and a rapid, successful introduction in the market is essential to gain a foothold before new contenders erode the opportunity. The selection of the most likely buyers is therefore important to direct the marketing efforts optimally. An international and a regional field study were carried out to identify the profile of organizations and individuals most likely to adopt an innovation in the computer field. These findings coupled with data base marketing techniques seem promising for a higher success rate in reaching the early adopters (lead users), making it possible to establish a first-mover advantage. The suggested approach can be used in other industries in rapid change.     

The new product development process for commercial financial services

The attention of senior executives in the financial services industry is increasingly being focused on how well the new product development process is working within their institutions. This focus on product development results from the combined pressures of increased competition, a rapidly changing marketplace, new technology, and new and pending legislative changes. All of these factors underscore the need to be able to design, develop, and launch, in a timely fashion, new products that are winners. A strong new product initiative is now considered an essential weapon in both offensive and defensive initiatives.To achieve their goals, executives are increasingly reexamining their organizations' approach to development and launch of new products to determine if the process can be redesigned for faster reaction time, better utilization of limited resources and improved success rates. This article examines the new product development process within the setting of corporate/commercial financial services. Its conclusions provide executives with some broad principles for their own new product processes to help them in their quest for competitive advantage through winning new products.     

Localizing Land Governance,Strengthening the State: Decentralization and Land Tenure Security in Uganda

Decentralization of land governance is expected to significantly improve land tenure security of small‐scale farmers in Africa, through ensuring better protection of their assets and reducing land‐related conflicts. This paper, however, cautions not to have too high expectations of transferring responsibilities for land administration and dispute resolution to local government bodies. Field research in Mbarara District in south‐western Uganda brings out how decentralization has limited impacts in terms of localizing land services provision. Nonetheless, local land governance has transformed in important ways, as decentralization adds to institutional multiplicity, and fuels competition among state and non‐state authorities, and about the rules they apply. Rather than strengthening local mechanisms for securing tenure, the reforms introduce new forms of tenure insecurity, fail to transform local conventions of dealing with land disputes and delegitimize local mechanisms for securing tenure. In practice, decentralization has had limited effects in securing tenure for the rural poor, yet reinforces the presence of the state at the local level in diverse ways.     

Book reviews

Abstract

This article examines the cultural field of fitness as a network of producers, consumers, products and practices that has developed around the care of the body through physical exercise. Drawing on a thematic text analysis of US exercise manuals, the paper focuses on how the commercial fitness field naturalizes associations between physical exercise and leisure, and between leisure and self‐work. In particular, the analysis examines three themes and their relevance to our broader understanding of leisure in contemporary consumer society: the management of leisure time; the use of leisure for self‐investment strategies; and the promotion of consumption as the framework for leisure and an accompanying notion of pleasure. The fitness field casts light on how leisure more generally is constructed as a sphere of obligations to make productive use of one’s time, to improve one’s body and self, and to do so through the wares of the consumer marketplace. The cultural imaginary of leisure as a time of freedom from work and responsibility is thus recast, in an age of individualization, as a time of freedom to accomplish the work of self‐production.     

Perceived trust in contractual channel dyads: an exploratory investigation of Finnish food retailers

Distributor firms have found long-term contracting an effective means of gaining competitive advantage. To realize these benefits, the alliance should involve trusting others. However, contracts can also be one-sided rather than reciprocal, favouring the larger business partner. Should trust develop naturally where there are formal contracts defining the terms of the relationship? And what inducements should a supplier take to gain retailers' trust? The trade-off is further complicated when the retailers operate in a small market with few suppliers and high barriers to entry. This study focuses on these questions. We use original field data from Finnish food retailers who have signed a written agreement with their focal wholesaler. We find that maintaining autonomy increases trust in the relationship. We also find that regular communication in the dyad and balance between perceived rewards and contributions are associated with higher levels of trust. In turn, intrachannel competition strongly reduces retailers' trust in the dyad.
