We build and estimate a novel TANK model with partially unfunded debt to study whether the record high debt-to-GDP ratio threatens US inflation stability. In response to business cycle shocks, the monetary authority controls inflation, and the fiscal authority stabilizes debt. The central bank...

In the early 2020s sharp surge of inflation, unprecedentedly high levels of government debt and deficits fueled attention for the Fiscal Theory of the Price Level (FTPL). This theoretical framework for fiscally induced inflation is well-known and controversially discussed. However, empirical...
