The theoretical literature generally finds that government spending multipliers are bigger than unity in a low interest rate environment. Using a fully nonlinear New Keynesian model, we show that such big multipliers can decrease when 1) an initial debt-to-GDP ratio is higher, 2) tax burden is...

This paper studies the main channels through which interest rate normalization has fiscal implications in the United States. While unexpected inflation reduces the real value of government liabilities, a rising policy rate increases government financing needs because of higher interest payments...

A New Keynesian model allowing for an active monetary and passive fiscal policy (AMPF) regime and a passive monetary and active fiscal policy (PMAF) regime is fit to various U.S. samples from 1955 to 2007. Data in the pre-Volcker periods strongly prefer an AMPF regime, but the estimation is not...

We analyse optimal monetary and fiscal policy in a New-Keynesian model with public debt and inflation persistence. Leith and Wren-Lewis (2007) have shown that optimal discretionary policy is subject to a ''debt stabilization bias'' which requires debt to be returned to its pre-shock level. This...
