Implementing reverse e-auctions: A learning process

Reverse e-auctions, which enable suppliers to compete on-line in real-time, are changing the way organizations select their suppliers. We explore how five large firms in different industries learned to use e-auctions, and how e-auctions were integrated into their purchasing processes. To successfully implement e-auctions, organizations should: (1) build e-auction competencies; (2) organize for knowledge management; (3) create a holistic sourcing process; (4) focus on the total cost of ownership; and (5) experiment with e-auction designs. Key observations are drawn from the case studies, and implications for supply managers are presented.     

Does success diminish competitive responsiveness? Reconciling conflicting perspectives

Previous research provides conflicting evidence of the association between the past performance of a business and its competitive responsiveness, with researchers observing both positive and negative relationships. To clarify this issue, the authors test a model using survey data from the retailing industry. The model delineates direct and indirect mediated paths through ability to respond, motivation to respond, and awareness of competitors’ actions to show how past performance can have both positive and negative influence on competitive responsiveness. However, the overall impact of past performance of an organization on its competitive responsiveness is positive. The implications of these findings for research, practice, and theory are discussed.

Static and dynamic efficiency of pollution control strategies

A great deal of the economic literature on pollution control strategies concentrates on the efficiency of environmental policy instruments. Most analytical studies in this field show that market instruments are more efficient with respect to the cost of pollution abatement of a given number of polluters than non-market instruments. According to several analytical studies, market instruments should also be more efficient with respect to innovation in pollution abatement equipment than non-market instruments. In the empirical literature a great number of case studies exist with estimations of the savings of abatement costs of market instruments in a situation without technological progress. Empirical studies about the impact of environmental policy market instruments on the abatement costs in situations with technological progress are lacking.The purpose of this paper is to fill this gap. The paper deals with an empirical estimation of abatement costs for the emission of SO₂ of coal-fired electricity units in the Netherlands from 1985 to 2000. First, the working of market instruments and non-market instruments (the existing environmental policy of the Dutch government) is simulated in a static situation. Second, we analyse the learning effects of flue gas desulphurization. The efficiency advantage of market instruments turns out to be larger in a situation of technological progress than in a static situation.

Competitive decision making: Two and a half frames

We argue that the study of competitive decision making has been heavily influenced by the frames of reference that are adopted by researchers. The dominant economic frame and the emergent behavioral frame describe largely separate phenomena and have little overlap. Drawing from examples of learning in games and markets, we show how each of these frames falls short of capturing some interesting elements in competitive decisions. We then describe how a coevolutionary perspective may be emerging as an integrative paradigm for the study of competitive decisions.This paper was prepared for the conference, Understanding Competitive Decision Making. Comments by the participants of that conference and Paul Shoemaker are gratefully acknowledged, as are discussions with Colin Camerer, Eldar Shafir, and Sharoni Shafir.
