This paper investigates the existence of a possible media bias by analyzing the impact of automobile manufacturer’s advertisements on automobile reviews in a leading German car magazine. By accounting for both endogeneity and sample selection using a two-step procedure, we find a positive...

Using examples for each type of model, we consider dynamic games, differential games, and simulation as alternative ways of extending the standard static economic model of conflict to study patterns of conflict dynamics. It turns out that computational requirements and theoretical difficulties...

Although a large body of research has examined the effects of unions on the wage distribution, surprisingly little attention has been devoted to the effects of unions on the distribution of income. This paper examines the long-run relationship between unionization and income inequality for a...

This paper analyses the incentives of a vertical integrated Internet service provider (ISP) to block competitors from content markets. Using a simple model we find that the ISP does not block competing content providers as long as the contents are differentiated sufficiently. Exclusion only...

Wir illustrieren den Einsatz von Simulationstechniken zur Betrachtung komplexer Dynamiken in asymmetrischen Konfliktsituationen mit begrenzt rationalen Akteuren. Dazu wird erst ein formaler Modellrahmen entwickelt, dessen Steady state wir bestimmen. Darauf baut eine Umsetzung des Modells in...

This paper deals with discrete labour supply decisions of different groups of persons in response to a change in net wage rates. The centrepiece of this approach is individuals' switching between working time categories, while facing switching costs that arise when people expand or reduce...

This paper considers optimal linear tax structures that are differentiated according to group membership. Groups can be heterogeneous with respect to both preferences and abilities. Contrary to most arguments in favour of tax privileges for certain groups, e.g. gender-based taxation, it is shown...
