We discuss conditions for the Aubin property of solutions to perturbed cone constrained programs, by using and refining results given in Klatte-Kummer "Nonsmooth Equations in Optimization", Kluwer, 2002. In particular, we show that constraint nondegeneracy and hence uniqueness of the multiplier is necessary for the Aubin property of the critical point map. Moreover, we give…

We show that the optimal asset allocation for an investor depends crucially on the theory with which the investor is modeled. For the same market data and the same client data different theories lead to different portfolios. The market data we consider is standard asset allocation data. The client data is determined by a standard risk profiling question and the theories we apply are…

This article introduces one emergent theoretical perspective from the North American research field of organizational communication that has come to be called “communication constitutes organization“ (CCO). The CCO perspective ascribes to communication a fundamental role in the constitution of organizations: Organizations basically consist of interconnected events of communication.…

This paper develops a model of a cooperative enterprise and compares it to a vertically separated market. In our model of a multi-stage production process, agents can acquire costly knowledge to decrease production costs. Our model shows that the cooperative acquires less non-generalizable knowledge than the market, but more generalizable knowledge if the large member in the…

Most of today’s manufacturing companies are organized in networks. Discussions concerning these networks include the global footprint, but hardly how the sites can be successfully coordinated. Leaning at coordination mechanisms known from team sports, this article provides five tactics of how the network coordination can be done successfully. These include a consequent reassessment…

Based on a model of asymmetric competition between a pay and a free media platform, this paper investigates advertising pricing models. The pay media platform generates revenues from media consumers through subscription fees, while the free media platform generates revenues from charging advertisers either on a lump-sum basis (regime A) or on a per-consumer basis (regime B). We show…
