Pay-as-You-Go Financing and Capital Outlay Volatility: Evidence from the States over Two Recent Economic Cycles

Pay-as-you-go (pay-go or cash) and pay-as-you-use (pay-use or debt) are two mechanisms to finance capital projects. While pay-go faces multiple constraints, pay-use smoothes outlays, stabilizes tax rates, and improves inter-generational equity. Thus, pay-use has dominated infrastructure financing for decades. In recent years, there has been revived academic interest in pay-go as an alternate financing mechanism; however, there is a large gap in the literature and inadequate evidence on the effects of pay-go, especially its effects on capital outlay volatility. This paper fills in the niche. Examining state experience over the two recent economic cycles, this paper finds evidence that suggests that paygo is associated with lower volatility in capital spending in the long run, but may increase short-run variability. We recommend that states couple pay-go in boom years with pay-use in lean years. In unison, the two mechanisms can reduce aggregate volatility and increase long-run stability of capital expenditures.
