Changing the income tax progressivity in labour markets with collective wage bargaining generates a trade-off. On the one hand, higher progressivity distorts individual labour supply decisions at the hours-of-work margin, on the other hand, it reduces unemployment by exerting downward pressure...

This chapter reviews options of labour market modelling in a CGE framework. On the labour supply side, two principal modelling options are distinguished and discussed: aggregated, representative households and microsimulation based on individual household data. On the labour demand side, we...

In labour markets with collective wage bargaining higher progressivity of the labour income tax creates a trade-off. On the one hand, wages are lowered and unemployment decreases, on the other hand, the individual labour supply decision is distorted at the hours-of-work margin. The optimal level...

When we analyse the labour market consequences of labour tax reforms in a model of firm-union wage bargaining, minor changes in the formulation of the union's fallback option can have drastic effects. This paper compares two variants of the model in which either workers have no reemployment...

The employment effects of an ecological tax reform depend decisively on the presence of a profit tax and on the extent to which profits are taxed. This is shown in a model where firms have monopoly power on product markets and bargain over wages with unions on the labour market. In the setting,...

We compare two options of integrating discrete working time choice of heterogenous households into a general equilibrium model. The first, known from the literature, produces household heterogeneity through a working time preference parameter. We contrast this with a model that directly...

In the tax policy debate, differentiation of value-added taxes is often justified by distributional concerns. Our quantitative analysis for Germany indicates that such concerns are misplaced. We find that the abolition of VAT differentiation has only negligible redistributive effects. Instead,...

Labour market reforms that are designed to stimulate labour supply at the lower end of the wage distribution can never be precisely restricted to affect only the target group. Spillovers to and feedback from other segments of the labour market are unavoidable and may counteract the direct...
