We consider the implications of ethical behaviour on the effect of a redistributive tax-transfer system. In choosing their labour supplies, individuals take into account whether their tax liabilities correspond to what they view as ethically acceptable. If tax liabilities are viewed as ethically...

A framework is developed in which the formation of gangs --- the criminal market structure --- is endogenous. We examine the impact of crime deterrence in this framework. It is shown that for a given gang structure, an increase in deterrence reduces criminal output. However, under identifiable...

Within a class action suit, similarly injured individuals can collectively obtain compensation through the justice system. Damage averaging occurs when the compensation awarded by the court to individual members is partly or completely determined by the average damage of the class. The key role...
