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...

In a social custom model of union membership with wage bargaining, higher levels of company taxes lower wages while having uncertain employment effects. A higher marginal income tax rate increases employment. Changes solely in the level of income taxation, retaining marginal rates, have...

Various taxes influence wage and employment outcomes in efficiency wage models. These findings are extended by incorporating more comprehensive tax functions, additional tax parameters, union-firm wage bargaining, and balanced budget restrictions. Moreover, the importance of different effort...

In a unionised labour market, a substitution of a payroll for an income tax will not alter employment if tax obligations are fulfilled. However, if workers or firms can evade taxes this irrelevance result might no longer apply. This will especially be the case if the fine for tax evasion depends...

In an efficiency wage economy with variable profits, a shift from payroll to employment taxes will reduce unemployment if the tax level is held constant at the initial wage. However, unemployment will rise if firms are constrained to zero profits in the long-run and if tax revenues are constant....

It is often argued that the quantity which is traded on the market is independent of the side of the market which is taxed. However, this assertion need not hold, especially in imperfectly competitive markets like that for labour. Taking an efficiency wage economy as an example, it is shown that...
