Hotellings berühmtes "Prinzip der minimalen Differenzierung" behauptet, dass zwei Firmen, die sich miteinander in räumlichem Wettbewerb befinden, dieselbe Position wählen. Wenn man räumlichen Wettbewerb als Modellierung von Produktdifferenzierung versteht, bedeutet dieses, dass die Firmen...

Hotelling’s famous ‘Principle of Minimum Differentiation’ suggests that two firms engaging in spatial competition will decide to locate at the same place. Interpreting spatial competition as modeling product differentiation, firms will thus offer products that are not differentiated and...

Chapter 2 examines whether a position in a search list (e.g. on a sales platform) can signal the quality of an experience good, if firms are allowed to pay for it. We show that it can do so, if vertical differentiation between firms is high, while it cannot, if it is low. Intuitively, if...

We suggest two alternatives to the Lovász-Shapley value for non-negatively weighted TU games (Casajus and Wiese, 2017. Int. J. Game Theory 46, 295-310), the dual Lovász-Shapley value and the Shapley² value. Whereas the former is based on the Lovász extension operator for TU games (Lovász,...

A growing literature has shown that behavioral biases influence consumer choices. Such so-called internalities are ubiquitous in many settings, including energy efficiency investments and the consumption of sin goods, such as cigarettes and sugar. In this paper, we use a mechanism design...
