In a partial equilibrium setting without price uncertainty, the balanced-budget substitution of an ad valorem tax on output for a specific (unit) tax can enhance welfare in imperfectly competitive markets and is without impact in a competitive world. This paper demonstrates that a substitution...

A strictly risk-averse individual with an exogenous gross income in period one can acquire human capital in the same period and evade taxes. Period-two income rises with educational investments in period one and can also be hidden from tax authorities. It is shown that a greater tax...

A higher unemployment compensation increases the incentive to shirk in efficiency wage models. If there is a stronger dependence of unemployment benefits on current earnings, these incentives will be reduced. An unemployment insurance with earnings-related benefits is thus characterised by...
