​The paper concentrates on illustrating and assessing central banks' liquidity operations during the crisis that started in August 2007. In addition to the ECB, the central banks of Sweden, Switzerland, the United Kingdom, Australia, Japan, Canada and the United States are analyzed. During the...

We examine global dynamics under infinite-horizon learning in New Keynesian models where the interest-rate rule is subject to the zero lower bound. As in Evans, Guse and Honkapohja (2008), the intended steady state is locally but not globally stable. Unstable deflationary paths emerge after...

Disinflationary episodes are a valuable source of information for economic agents trying to learn about the economy. In this paper we are particularly interested in how policymakers can themselves learn by disinflating. The approach differs from the existing literature, which typically focuses...

In response to the Great Financial Crisis, the Federal Reserve and the Bank of England have adopted unconventional monetary policy instruments. We investigate if one of these, purchases of long-term government debt, could be a valuable addition to conventional short-term interest rate policy...

We study whether the mechanism design in the central bank liquidity auctions matters for the interbank money market interest rate levels and volatility. Furthermore, we compare different mechanisms to sell liquidity in terms of revenue, efficiency and auction stage interest rate levels and...

We examine global dynamics under learning in a nonlinear New Keynesian model when monetary policy uses price-level targeting and compare it to inflation targeting. Domain of attraction of the targeted steady state gives a robustness criterion for policy regimes. Robustness of price-level...

We examine global economic dynamics under infinite-horizon learning in a New Keynesian model in which the interest-rate rule is subject to the zero lower bound. As in Evans, Guse and Honkapohja, European Economic Review (2008), we find that under normal monetary and fiscal policy the intended...

We study the effects of model uncertainty in a simple New-Keynesian model using robust control techniques. Due to the simple model structure, we are able to find closed-form solutions for the robust control problem, analysing both instrument rules and targeting rules under different timing...

Inflation targeting involves using all available information in stabilizing inflation around some target rate (Svensson, 2003). Inflation is typically at the very end of the transmission mechanism and hence its determination is subject to much model uncertainty which the central bank will want...

Monetary policy transmission lags create credibility problems for the inflation-targeting policy maker who acts under discretion. We show that if prices react to monetary policy with a longer lag than output, the welfare maximizing inflation-targeting policy implies no policy stabilization of...
