Optimal Pricing of Nondurables when Demand is Dynamic and Stochastic

This paper derives optimal pricing strategies for nondurables if demand is sluggish and stochastic. The puzzling result is that moving from a static demand to a dynamic relation alters the marketing strategy dramatically if the equilibrium demand is convex (in price): the profit maximizing price policy is to switch between a low and a high price depending on current demand while a continuous price policy is optimal for concave demand relations. However, the formal existence of such a price switching policy is restricted to the anyway more realistic stochastic version of the model. The clear cut implications of the model provide also a criterion to test empirically the characteristics and the optimality of actual price strategies.     

Majority voting on restricted domains

In judgment aggregation, unlike preference aggregation, not much is known about domain restrictions that guarantee consistent majority outcomes. We introduce several conditions on individual judgments sufficient for consistent majority judgments. Some are based on global orders of propositions or individuals, others on local orders, still others not on orders at all. Some generalize classic social-choice-theoretic domain conditions, others have no counterpart. Our most general condition generalizes Sen's triplewise value-restriction, itself the most general classic condition. We also prove a new characterization theorem: for a large class of domains, if there exists any aggregation function satisfying some democratic conditions, then majority voting is the unique such function. Taken together, our results support the robustness of majority rule.     

Beyond the Bounded Instrumentality in Current Corporate Sustainability Research: Toward an Inclusive Notion of Profitability

We argue that the majority of the current approaches in research on corporate sustainability are inconsistent with the notion of sustainable development. By defining the notion of instrumentality in the context of corporate sustainability through three conceptual principles we show that current approaches are rooted in a bounded notion of instrumentality which establishes a systematic a priori predominance of economic organizational outcomes over environmental and social aspects. We propose an inclusive notion of profitability that reflects the return on all forms of environmental, social, and economic capital used by a firm. This inclusive notion of corporate profitability helps to redefine corporate profitability as if sustainability matters in that it overcomes the bounded instrumentality that impairs current research on corporate sustainability. We apply this notion to different car manufacturers and develop conceptual implications for future research on corporate sustainability.     

The 'magic formula' for linearly edge-reinforced random walks

Linearly edge-reinforced random walk on a finite graph is a mixture of reversible Markov chains with an explicitly known mixing measure. We give a new proof of this fact.     

IT Competence in Internet Founder Teams

In the Net Economy, numerous start-ups relying on Internet-based business models have been founded in the recent years. In these ventures IT experts are confronted with different requirements to those of traditional software development. It can thus be assumed that founders in the Net Economy prefer IT experts with a different competence profile. Based on an elaborate competence model for IT experts in Internet-based ventures, founder preferences are empirically analyzed and related to the novelty of the venture’s product. An adaptive conjoint analysis is applied to obtain utility values for single components of competence. Using cluster analysis, four different competence profiles are identified which correspond to prototypical IT experts bearing different core functions. Data analysis suggests that founders with more innovative products differ from founders with less innovative products in their perception of the optimal IT expert’s competence profile. The results have implications both for career decisions of IT experts and for founders of Internet start-ups who are looking for co-founding IT experts. This study is one of the first to explicitly focus on IT competence in Internet-based ventures. It therefore extends existing research on IT competence to a new and dynamic industry.     

Why is research on management accounting change not explicitly evolutionary? Taking the next step in the conceptualisation of management accounting change

In this article we discuss the evolutionary foundation of the OIE-guided management accounting change research building on the framework of [Scapens R.W. 1994. Never mind the gap: towards an institutional perspective on management accounting practice. Management Accounting Research, 5, 301–321.] and [Burns, J. and Scapens, R.W., 2000. Conceptualizing management accounting change: an institutional framework. Management Accounting Research, 11, 3–25.]. We argue that research on management accounting change should be based on evolutionary theory, but that the full potential of evolutionary theory has not yet been described or used in management accounting research. The conceptualisation and understanding of management accounting change can be improved and expanded if the evolutionary approach is developed beyond the general belief that it describes only small and gradual, often slow, changes. In this article we show that an evolutionary perspective on management accounting change implies that management accounting’s development is explained as the interaction between the evolutionary sub processes of retention (inheritance), variation and selection. Thus, both continuity and change are seen as evolutionary outcomes. These processes follow the cumulative causality that Charles Darwin proposed and Thorstein Veblen applied to the social sciences. Such a comprehensive theory, here labelled Universal Darwinism, must, however, be given substance with supporting details.     

Strategic foresight for collaborative exploration of new business fields

To ensure long-term competitiveness, companies need to develop the ability to explore, plan, and develop new business fields. A suitable approach faces multiple challenges because it needs to (1) integrate multiple perspectives, (2) ensure a high level of participation of the major stakeholders and decision-makers, (3) function despite a high level of uncertainty, and (4) take into account interdependencies between the influencing factors. In this paper, we present an integrated approach that combines multiple strategic-foresight methods in a synergetic way. It was applied in an inter-organizational business field exploration project in the telecommunications industry.
