Assuming unemployment to be caused by efficiency wages, it is shown that a balanced-budget shift from a payroll tax to a VAT will increase employment if the rise in the VAT does not alter consumer prices. If the effects of a shift from SSC to the VAT on the worker’s effort are neutralised, for example, by imposing a constant wedge, the employment impact will depend on the nature of the unemployment compensation system. %K Efficiency wages %K social security contributions %K unemployment %K value-added tax
