In the low inflation and low interest rate environment that prevailed over the period 2013-2020, many argued that besides expansionary monetary policy, expansionary fiscal policy could also support central banks' efforts to bring inflation closer to target. During the pandemic, proper alignment...

This paper reviews recent advances in the specification and estimation of Bayesian Vector Autoregressive models (BVARs). After describing the Bayesian principle of estimation, we first present the methodology originally developed by Litterman (1986) and Doan et al. (1984) and review alternative...

Keynesian theory predicts output responses upon a fiscal expansion in a small open economy to be larger under fixed than floating exchange rates. We analyse the effects of fiscal expansions using a New Keynesian model and find that the reverse holds in the presence of sovereign default risk. By...

In standard macroeconomic models, debt sustainability and price level determinacy are achieved when fiscal policy avoids explosive debt and monetary policy controls inflation, irrespective of the relative strengths of each policy stance. We examine how these policy requirements for equilibrium...

We estimate the effects of monetary policy shocks across contractionary and expansionary fiscal regimes in the euro area. An expansionary monetary policy shock leads to an increase in inflation and output growth, but only when it occurs in the expansionary fiscal regime. In a contractionary...

We study the stabilization properties and welfare implications of a fiscal capacity in a New Keynesian model for a monetary union. A novel feature of the model is that access to the fiscal capacity is conditional on a country’s public debt accumulation being sufficiently low. Likewise, the...

Earlier studies on the equilibrium properties of standard dynamic macroeconomic models have shown that an inflation-targeting central bank imposes strict budgetary requirements on fiscal policy needed to obtain a unique and stable equilibrium. The failure of only one fiscal authority within a...
