Discount Rates,Debt Maturity,and the Fiscal Theory

This paper examines how the transmission of government portfolio risk arising from maturity operations depends on the stance of monetary/fiscal policy. Accounting for risk premia in the fiscal theory allows the government portfolio to affect expected inflation, even in a frictionless economy. The effects of maturity rebalancing on expected inflation in the fiscal theory depend directly on the conditional nominal term premium, giving rise to an optimal debt-maturity policy that is state-dependent. In a calibrated macrofinance model, we demonstrate that maturity operations have sizable effects on expected inflation and output through our novel risk transmission mechanism.
