Should monetary policy be more aggressive or more cautious when facing uncertainty on the relationship between macroeconomic variables? This paper's answer is: “it depends” on the degree of persistence of the shocks that hit the economy. The paper studies optimal monetary policy in a basic...

This paper studies optimal robust monetary policy when the central bank imperfectly observes potential output and has Knightian uncertainty about the intertemporal elasticity of substitution and the slope of the Phillips curve. The literature on optimal robust monetary policy has focused on...

The question of how climate change and weather fluctuations affect the economy is high on the economic research agenda, but the quantification of the effects of temperatures at infra-annual frequencies still remains an open issue. Using daily county-level data since 1970, I construct quarterly...

Using a new monthly dataset on bank-level lending rates, we study the transmission of conventional and unconventional monetary policy in the euro area via shifts in the supply of credit. We find that a bank lending channel is operational for both types of measures, though its functioning...

This paper evaluates the macroeconomic effects of a monetary and fiscal policy mix implemented in a two-region monetary union in response to the COVID-19 shock. The pandemic is modelled as a mix of recessionary demand and supply shocks affecting both regions simultaneously and symmetrically,...

The applied literature on adaptive learning has mostly focused on small, linear models, with homogenous expectations. In non-linear models heterogeneous expectations prevail and the process through which agents select (and change) a forecasting model becomes a necessary ingredient of the...

We evaluate the global macroeconomic effects of fiscal and monetary policy measures to counterbalance secular stagnation by simulating a five-region New Keynesian model of the world economy, calibrated to the United States (US), the euro area (EA), Japan (JP), China (CH), and the rest of the...

This paper evaluates the macroeconomic effects of the Eurosystem's expanded Asset Purchase Programme (APP) under alternative strategies as regards (i) the unwinding of asset positions accumulated under the APP and (ii) communication of current and future paths of the policy rate (forward...

This paper evaluates the macroeconomic effects of purchases of long-term sovereign bonds by a central bank in a monetary union when (1) the private sector faces tight financial conditions and (2) the zero lower bound (ZLB) on the policy rate holds. To this end, we calibrate a dynamic general...

We probe the scope for reacting to house prices in simple and implementable monetary policy rules, using a New Keynesian model with a housing sector and financial frictions on the household side. We show that the social welfare maximizing monetary policy rule features a reaction to house price...
