Fiscal policy in a Real-Business-Cycle model with labor-intensive government services and endogenous public sector wages and hours

Motivated by the high public employment, and the public wage premia observed in Europe, a Real-Business-Cycle model, calibrated to German data (1970-2007), is set up with a richer government spending side, and an endogenous private-public sector labor choice. To illustrate the effects of fiscal policy, two regimes are compared and contrasted to one another exogenous vs. optimal (Ramsey) policy case. The main findings from the computational experiments performed in this paper are: (i) The optimal steady-state capital tax rate is zero; (ii) A higher labor tax rate is needed in the Ramsey case to compensate for the loss in capital tax revenue; (iii) Under the optimal policy regime, public sector employment is lower, but government employees receive higher wages; (iv) The benevolent Ramsey planner provides the optimal amount of the public good, substitutes labor for capital in the input mix for public services production, and private output; (v) Government wage bill is smaller, while public investment is three times higher than in the exogenous policy case.
