DO BALANCED-BUDGET RULES INCREASE GROWTH?

This study tests the hypothesis that balanced-budget rules (BBRs) that restrict public borrowing to investments in public infrastructure increase growth by increasing the productivity of debt, either because investments in public infrastructure are more productive than other uses for which states borrow funds or because BBRs lower borrowing costs. Results are based on data at 5-year intervals for 49 US states over the period 1957-2007. The tests strongly support the hypothesis that BBRs increase growth by increasing the productivity of debt and withstand a variety of robustness checks, including alternative lags, exogeneity tests, GMM estimation, a placebo test, and the influence of outliers.
