Sticky Spending, Sequestration, and Government Debt
Facundo Piguillem

Abstract
Once established, government spending programs tend to continue. A commonly
held view is that spending inertia leads to unsustainable debt, ultimately requiring fiscal
adjustments such as “sequestration.” We show that by insuring against political turnover,
inertia may reduce politicians’ incentives to accumulate debt. However, large preexisting
commitments and the prospect of future stabilization can lead to overspending to dilute
past administrations’ commitments. Finally, we show that political polarization amplifies
incentives to prioritize inertial programs, potentially explaining the increased share of
mandatory spending in the U.S. budget.
