The legal regulations require the minimum wage in Germany to be adjusted biennially which gives rise to a policy discontinuity. From the perspective of rational expectations models, such policy features render standard local approximation techniques infeasible. The paper presents a stylised...

The macroeconomic effects on growth, investment and private sector employment of different ways of rolling back the welfare state are analysed. Cutting public spending on private goods induces a lower interest rate, a higher wage, a lower capital stock and a fall in employment. Cutting public...
