This paper presents evidence that stringent balanced budget requirements en
forced in some U.S. states have exacerbated business cycles in those states
. The effect is not apparent directly. However, among states where fiscal p
olicy may have more macroeconomic consequences (large states), the differen
ce in volatility between states with lenient and strict balanced budget rul
es is larger (more negative or less positive) than among states where fisca
l policy may be less relevant (small states). Two implications are suggeste
d: (1) states' fiscal policies have real macroeconomic consequences, and (2
) strict balanced budget requirements increase business cycle volatility.
