Zeitinkonsistenz wird im Allgemeinen grob als das Phänomen verstanden, dass einEntscheider, der einen bestimmten optimalen Plan gefasst hat, diesen bei einer späteren Reoptimierung revidiert, ohne dass sich unterdessen relevante Unsicherheit aufgelöst hätte. Die wirtschaftspolitische und...

Gegenstand dieses Aufsatzes sind die fundamentalen Probleme liberaler Argumente in den Wirtschaftswissenschaften. Anders als dies die Zyklen in der Dogmengeschichte nahelegen, erweist sich die gegenwärtige Krise des Wirtschaftsliberalismus dabei nicht als eine vorübergehende 'Rezession',...

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 presence of cognitive dissonanceattenuates tax evasion as individuals dislike allowing their true bevhaviour to diverge from their public statement...

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...

Our very simple model serves to illustrate that it is useful to think of corruption as implicit privatisation cum auction, i.e. of the state relegating decision-making authority to a private person, who then auctions the rents off.

We review, and extend, one of the classic dynamic models of conflict in economics by Richardson (1919) and Boulding (1962). It turns out that the stability properties of the model change if one takes a more realistic 'incrementalist' view, and that chance / friction can easily be incorporated...

We review, and extend, one of the classic dynamic models of conflict in economics by Richardson (1919) and Boulding (1962). Restrictions on parameters are relaxed to account for alliances and for peace-keeping, yielding new dynamic patterns of conflict. In addition, we explore an incrementalist...
