The Covid-19 pandemic found policymakers facing constraints on their ability to react to an exceptionally large negative shock. The current low interest rate environment limits the tools the central bank can use to stabilize the economy, while the large public debt curtails the efficacy of...

While high uncertainty is an inherent implication of the economy entering the zero lower bound, deflation is not, because agents are likely to be uncertain about the way policymakers will deal with the large stock of debt arising from a severe recession. We draw this conclusion based on a...

We show that policy uncertainty about how the rising public debt will be stabilized accounts for the lack of deflation in the US economy at the zero lower bound. We first estimate a Markov-switching VAR to highlight that a zero-lower-bound regime captures most of the comovements during the Great...

What happens if the government's willingness to stabilize a large stock of debt is waning, while the central bank is adamant about preventing a rise in inflation? The large fiscal imbalance brings about inflationary pressures, triggering a monetary tightening, further debt accumulation, and...

Low and stable inflation requires an appropriate fiscal framework aimed at stabilizing government debt. Historically, trend inflation is critically influenced by actual or perceived changes to this framework, while cost-push shocks only account for short-lasting movements in inflation. Before...

The growing asymmetry in the size of fiscal imbalances poses a serious challenge to the macroeconomic stability of the Euro Area (EA). We show that following a contractionary shock, the current monetary and fiscal framework weakens economic growth even in lowdebt countries because of the zero...

We develop a new class of general equilibrium models with partially unfunded debt to propose a fiscal theory of trend inflation. In response to business cycle shocks, the monetary authority controls inflation, and the fiscal authority stabilizes debt. However, the central bank accommodates...

Since the 2001 recession, average core inflation has been below the Federal Reserve's 2% target. This deflationary bias is a predictable consequence of a low nominal interest rates environment. When monetary policy faces the risk of encountering the zero lower bound, in.ation tends to remain...
