We characterise optimal discretionary monetary policy responses to cost-push shocks and to financial distress in the presence of model uncertainty. Under robust control, the central bank reacts more aggressively to both types of shocks, and less to the lagged policy rate, than if the true model...

The global financial crisis and the ensuing criticism of macroeconomics have inspired researchers to explore new modeling approaches. There are many new models that deliver improved estimates of the transmission of macroeconomic policies and aim to better integrate the financial sector in...

This paper starts from the observation that parameter instability and model uncertainty are relevant problems for the analysis of monetary policy in small macroeconomic models. We propose to deal with these two problems by implementing a novel ‘thick recursive modelling’ approach. At each...

Working with micro-founded loss functions to derive and analyse optimal policy ensures consistency with the model used and overcomes the misleading prescriptions that result from using exogenous ad hoc loss functions. However, when allowance is made for the fact that different theories of...

Recent research has shown that optimal monetary policy may display considerable price-level drift. Proponents of price-level targeting have argued that the costs of eliminating the price-level drift may be reduced if the central bank responds flexibly by returning the price level only gradually...

We study optimal monetary policy in a New Keynesian model at the zero bound interest rate where households use cash alongside house equity borrowing to conduct transactions. The amount of borrowing is limited by a collateral constraint. When either the loan to value ratio declines or house...

This paper studies the optimal long-run inflation rate in a labor search and matching framework in the presence of downward nominal wage rigidity. Optimal monetary policy features positive inflation in the long run; the optimal annual long-run inflation rate for the U.S. economy is slightly...
