Market representations in industrial marketing: Could representations influence strategy?

A central question in industrial marketing is whether the form in which the market of a firm is represented influences the marketing strategy. This question has been studied generally through case study research, and quantitative evidence is limited. In response to this limitation, this paper reports on a quasi-experiment investigating whether market representations have a constructive aspect in business. Empirically, this study compares two types of market representations - ostensive and performative - in order to test for influence exacted in two well-established strategies in industrial marketing - service focus and product differentiation. Results indicate that service focus is selected when market representations rely on agency in firms (i.e., performative), and product strategies are selected when structures are emphasized (i.e., ostensive). This paper contributes to methodology development by expanding the link between a case study approach and quasi-experiments explaining how quasi-experiments can replicate findings in industrial marketing.

The dual ladder: motivational solution or managerial delusion?

The 'Dual Ladder' reward system has been used for years by industry as an incentive system to motivate technical performance. Its effectiveness has been called into question on many occasions. The paper will report the results of a survey of nearly 1,500 engineers and scientists in nine U.S. organizations. In this survey, engineers were asked to indicate their career preferences in terms of increasing managerial responsibility, technical ladder advancement or more interesting technical work. Responses indicate marked age-dependent differences in response, particularly a strong increase in the proportion preferring more interesting project work over either form of advancement.

Industrial relationships and the effects of different types of connections

Emphasizing the primary and secondary functions in business networks, this paper is based on the presumption that the primary function of the focal dyadic relationship is connected to business, political, ancillary and competitive relationships, i.e. what has been denoted as the secondary function. The question is how these secondary functions affect the primary function. The conceptual view developed for the focal dyadic relationship is founded on the two key relationship concepts of trust and commitment. The empirical study is based on a survey of 353 firms and their most important customer relationships. The analysis examines nine hypotheses through a structural model in LISREL. Conclusions from the statistical test show the heterogeneity in the impacts of these different types of connections on trust and commitment. Knowledge of the impact of these connections can aid the further understanding of relationship connections and also assist business firms in developing strategies towards these units.     

Should System Firms Develop Complementary Products? A Dynamic Model and an Empirical Test

While Nintendo develops many video games internally, Apple is only marginally involved in the development of iPhone applications. This paper addresses the question: to what extent and how should system firms be involved in the development of complementary products for their “core products”? These core products may include video consoles, electronic book readers, etc. This is a highly relevant question, because the success of core products depends strongly on their complementary products, e.g., video games and electronic books. This study proposes a dynamic model for the degree that system firms should be involved in complementary product development by considering, as contingency factors, the novelty of the core, and the novelty of the complementary products. Both novelties influence the degree to which system firms should be involved in the development of complementary products. In terms of a system firm's involvement, this study makes a distinction between the degree of integration and the degree of ownership. The degree of integration reflects the extent to which the system firm is actively involved in the coordination of the complementary product, e.g., to ensure that the complementary product is optimally aligned with its core product and that the full potential of the core product is achieved. The degree of ownership reflects the extent to which the system firm finances the development of the complementary product and therefore, the degree of formal control authority over the complementary product. This model was tested using data from a survey of 99 development projects for mobile telecommunications applications. The results reveal that integration by the system firm contributes to the performance of complementary products for new core products but has a negative effect if a new complement is developed for a mature core product. In addition, ownership contributes to performance if both the core and complementary products are new. In other circumstances, a clear effect of ownership by the system firm on performance is not found. The implications of our findings are that system firms should be strongly involved in complementary product development when they introduce a new core product, and even more so if the complementary products are new. However, they should decrease their degree of involvement over time as the core product matures and, again, even more so if the complementary product is new. The paper concludes by providing practical implications for system firms in the mobile telecommunications industry and beyond.     

Decentralized control of cooperative and autonomous agents for solving the distributed resource allocation problem

This paper focuses on the decision-making mechanism of coordination protocol for a multi-agent system in collaborative, distributed environment requiring resource allocation solutions. The model of distributed collaboration network (DCN) for distributed resource allocation is developed. The use of monitored viability of each agent as a feedback for the agent's reflexivity and goal adjustment mechanisms during the coordination process is introduced. Question: Will (can) a multi-agent system, as a whole, achieve efficient resource allocations, when each agent makes independent decisions, adjusted by feedback of its own viability measure to maximize its own goal based on limited information about the entire system? To investigate this question, experiments were conducted by using the parallel simulator TIE/Protocol to model the DCN and multi-agent system behavior.
