How to Starve the Beast: Fiscal Policy Rules


Abstract: Countries have widely imposed fiscal rules designed to constrain government spending and ensure fiscal responsibility. This paper studies the effectiveness and welfare implications of revenue, deficit and debt rules when governments are discretionary and prone to overspending. The optimal prescription is a revenue ceiling coupled with a balance budget requirement. For the U.S., the optimal revenue ceiling is about 15% of output, 3 percentage points below the postwar average. Most of the benefits can still be reaped with a milder constraint or escape clauses during adverse times. Imposing a single fiscal rule allows governments to comply without necessarily curbing spending; on their own, revenue ceilings are only mildly effective, while deficit and debt rules are altogether ineffective.
