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...

We combine two extensions of the differentiated duopoly model of Dixit (1979), namely Caminal and Vives (1996) and Brander and Spencer (2015a,b), to analyze the effect of consumer learning on firms' incentives to differentiate their products in models of Cournot and Bertrand competition....

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...

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...
