We analyze the strategic behavior of firms when demand is determined by a rule of thumb behavior of consumers. We assume consumer dynamics where individual consumers follow simple behavioral decision rules governed by imitation and habit as suggested in consumer research. On this basis, we...

We define an indirect evolutionary approach formally and apply it to (Tullock)contests. While it is known (Leininger, 2003) that the direct evolutionary approach in the form of finite population ESS (Schaffer, 1988) yields more aggressive behavior than in Nash equilibrium, it is now shown that...

I study a market model in which profit-maximizing firms compete in multi-dimensional pricing strategies over a consumer, who is limited in his ability to grasp such complicated objects and therefore uses a sampling procedure to evaluate them. Firms respond to increased competition with an...

We study the effects of disruption risk in a supply chain where one retailer deals with competing risky suppliers who may default during their production lead-times. The suppliers, who compete for business with the retailer by establishing wholesale prices, are leaders in a Stackelberg game with...

In this paper, we estimate the value of an Information Communication Technology (ICT) investment opportunity, modeled as a Real Option (RO), when there is competition threat that can influence negatively its value or even more eliminate it. We put our analysis in the revenue management concept,...

Die Arbeit behandelt die Musikverwertung mit Hilfe von Tonträgern und Netzen. Nach einem kurzen Abriß der Tonträgergeschichte wird der bestehende Rechtsrahmen im nationalen, europäischen und internationalen Kontext dargestellt. Die Anreize zur Musikproduktion und -verwertung werden...

A potentially dangerous product is supplied by a competitive market. The likelihood of a product-related accident depends on the unobservable precautions taken by the manufacturer and on the type of the consumer. Contracts include the price to be paid by the consumer ex ante and stipulated...
