The paper studies the short-run, transitional, and long-run output effects of permanent and temporary shocks in public consumption under various financing methods.To this end, a dynamic macroeconomic model for a closed economy is developed, which features a perfectly competitive final goods sector and a monopolistically competitive intermediate goods sector.Finitely lived households consume final goods, supply labor, and save part of their income.Amongst the findings for a permanent rise in public consumption are: (i) monopolistic competition increases the absolute value of the balanced-budget output multiplier; (ii) positive long-run output multipliers are obtained only if the generational turnover effect is dominated by the intertemporal labor supply effect; (iii) short-run output multipliers under lump-sum tax financing are smaller than long-run output multipli-ers if labor supply is elastic; and (iv) bond financing reduces the size of long-run output multipliers as compared to lump-sum tax financing and may give rise to non-monotonic adjustment paths if labor supply is sufficiently elastic and the speed of adjustment of lump-sum taxes is not too high.Temporary bond-financed fiscal shocks are shown to yield: (i) permanent effects on output; and (ii) negative long-run output multipliers.
