Investment in infrastructure is necessary for a strong, flexible, and growing economy. However, the relationship between public capital and economic growth is not linear. At a certain level, the tax burden associated with financing and maintaining public capital reduces the returns to private industry, which in turn reduces growth; also, different types of spending have different effects on growth. The short- and long-term growth-maximizing effects of public investment increase as the ratio of public to private capital stock rises to an optimal level (found to be about 61 percent); above that level, the growth effects decrease. The public-to-private ratio is below the optimal level throughout much of the country and government spending is not always directed toward the types of investment that have the most positive effects on growth. Good economic policy requires both increasing the public capital stock and reorienting government spending from consumption to investment in physical capital stock.

This paper develops and implements a neoclassical model of fiscal policy. The paper's main empirical hypothesis is that government non‐military investment spending is more expansionary than is either government consumption or military investment. The paper utilizes annual data to support the hypothesis. It finds that output "multipliers" for government non‐military investment significantly exceed unity while multipliers for government consumption and military investment lie below unity. The paper also finds that public sector deficits—both actual and cyclically adjusted—contain minor explanatory power for output when one controls for the effects of non‐military investment.
