We construct an endogenous growth model that includes productive public capital and government debt. We assume that the government debt-to-GDP ratio is gradually adjusted to a target level, reflecting the permanent commitment rules in the Stability and Growth Pact or the Maastricht Treaty in the European Union (i.e., the well-known 60% rule). These rules affect government borrowing and public investment. Here, we examine the welfare implications of the permanent commitment rules. We find that fiscal consolidation based on the rules improves social welfare. Moreover, the improvement in welfare accelerates as fiscal consolidation progresses more rapidly. Last, we also discuss and derive the optimal long-run debt-to-GDP ratio.

One part of the literature on endogenous growth concerns models where public infrastructure affects the private production process. An unsolved puzzle in this literature concerns observed public investment-to-output ratios for developed economies, which tend to fall short of theoretical model-based optimal ratios. We reexamine the optimal choice of public investment in a more general framework. This setting allows for long-lasting capital stocks, a lower depreciation rate for public capital than for private capital, an elasticity of intertemporal substitution that differs from unity, and the need to finance a nontrivial share of public services in output. Given other fundamentals in the economy, we show that the optimal public investment-to-output ratio is smaller for low-growth economies, for economies populated by consumers with low preferences for substituting consumption intertemporally, and when public capital is durable. For a calibrated economy, we show that a combination of these factors solves the public investment puzzle.

This paper considers an endogenous growth model with public capital and heterogeneous agents. Heterogeneity is due to differences in discount factors and inherent abilities. This allows us to closely approximate the 2007 U.S. income and wealth distributions. Government expenditures, including public investment, are financed through a progressive income tax along with a flat tax on consumption. Three revenue-neutral fiscal policy reforms are considered: (i) an increase in the degree of progressivity of the tax schedule that reduces the after-tax income distribution Gini coefficient to its lowest value over the period 1979–2009, (ii) a reduction in the progressivity ratio that causes the Gini coefficient of the wealth distribution to come close to 1, and (iii) an increase in the fraction of output allocated to public investment that has the same positive impact on the growth rate as reform (ii). It is shown that increasing investment in public capital is the only type of policy that simultaneously enhances growth and reduces both types of inequality (income and wealth). We also find that the public-investment-to-output ratio that maximizes social welfare crucially depends on the elasticity of the labor supply. With a more elastic labor supply the optimal ratio is 4.40%, whereas with a less elastic labor supply it is 5.53%.
