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...

We introduce public signals and cognitive dissonance into the standard Allingham-Sandmo- Yitzhaki (ASY) model of tax evasion. It turns out that the pres- ence of cognitive dissonance attenuates tax evasion as individuals dislike allowing their true bevhaviour to diverge from their public...

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...

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 compares student evaluation of teaching on the web site MeinProf.de to the standard evaluation procedures at German universities. While MeinProf offers the advantage of a broad, publicly available database, a number of theoretical and econometric problems emerge. Many of these...

Using a new panel dataset comprising publication and appointment data for 889 German academic economists over a quarter of a century, we confirm the familiar hypothesis that publications are important for professorial appointments, but find only a small negative effect of appointments on...

This paper is concerned with methods for analysing patterns of conflict. We survey dynamic games, differential games, and simulation as alternative ways of extending the standard static economic model of conflict to study patterns of conflict dynamics, giving examples for each type of model. It...

We analyse the long-run equilibrium and adjustment dynamics in three popular models of economic growth when property rights are absent. The results are compared to the outcome in the corresponding economy with secure property rights.

If firms demand heterogeneous working qualifications, each has to decide whether to choose its preferred qualification and be incompatible to other firms' qualifications or to standardize and choose the same qualification as other firms. The model analyses whether advanced training, which...
