Existing papers studying optimal monetary policy when the central bank makes errors in measuring potential output typically treat those errors as exogenous to the model of the economy. Here we show that this is not an innocuous assumption, and can have important implications for optimal monetary...

This paper offers several contributions to actual research and discussion on monetary policy. It clarifies the relationship between uncertainty of inflation persistence and optimal monetary policy and discusses the consequences of the recent Blanchard proposal to implement a higher inflation...

This paper studies the design of optimal time-consistent monetary policy in an economy where the planner trusts its own model, while a representative household uses a set of alternative probability distributions governing the evolution of the exogenous state of the economy. In such environments,...

Model uncertainty has the potential to change importantly how monetary policy should be conducted, making it an issue that central banks cannot ignore. In this paper, I use a standard new Keynesian business cycle model to analyze the behavior of a central bank that conducts policy with...

Inflation-targeting central banks have only imperfect knowledge about the effect of policy decisions on inflation. An important source of uncertainty is the relationship between inflation and unemployment. This paper studies the optimal monetary policy in the presence of uncertainty about the...

Post great financial crisis (GFC) of 2008-2009, there has been a surge in the macroeconomics literature on aggregate uncertainty. Although the recent literature has recognized adverse real effects of global uncertainty shocks in EMEs, the role of monetary policy in mitigating these effects is...

Large risk shocks give rise to cost-push effects in the canonical New Keynesian model. At the same time, monetary policy becomes less effective. Therefore, stochastic volatility introduces occasional trade-offs for monetary policy between inflation and output gap stabilisation. The cost-push...
