This paper analyzes the growth and employment effects of dynamic fiscal policies in an overlapping generations model with endogenous growth and imperfect labour markets. With balanced-budget policies, the modelled closed economy grows at a constant rate which is the higher, the lower are the labour tax rate and the unemployment rate. Both government Ponzi games and constant-flow budget policies are shown not to be feasible. Furthermore, while constant-stock fiscal policies are sustainable, an increase in the debt-to-capital ratio is accompanied by higher taxes, a rise in unemployment and lower economic growth.
