This paper examines what we have learned and how we should change our thinking about monetary policy strategy in the aftermath of the 2007-2009 financial crisis. It starts with a discussion of where the science of monetary policy was before the crisis and how central banks viewed monetary policy...

This paper, which is the introductory chapter in my book, "Monetary Policy Strategy", forthcoming from MIT Press, outlines how thinking in academia and central banks about monetary policy strategy has evolved over time. It shows that six ideas that are now accepted by monetary authorities and...

In this paper we examine how target ranges work in the context of a Barro-Gordon (1983) type model, in which the time-inconsistency problem stems from political pressures from the government. We show that target ranges turn out to be an excellent way to cope with the time-inconsistency problem,...

However, central banks can improve transparency in discussing that they do care about reducing output fluctuations . By describing procedures for how the path and horizon of inflation targets would be modified in the face of large shocks, by emphasizing that monetary policy will be just as...

This paper assumes that a central bank commits itself to maintaining an inflation target and then asks what measure of the inflation rate the central bank should use if it wants to maximize economic stability. The paper first formalizes this problem and examines its microeconomic foundations. It...

Central banks affect the resources available to fiscal authorities through the impact of their policies on the public debt, as well as through their income, their mix of assets, their liabilities, and their own solvency. This paper inspects the ability of the central bank to alleviate the fiscal...

Today, all major central banks pay or collect interest on reserves, and stand ready to use the interest rate as an instrument of monetary policy. We show that by paying an appropriate rate on reserves, the central bank can pin the price level uniquely to a target. The essential idea is to index...

Analysis of quantitative easing (QE) typically focus on the recent past studying the policy's effectiveness during a financial crisis when nominal interest rates are zero. This paper examines instead the usefulness of QE in a future fiscal crisis, modeled as a situation where the fiscal outlook...

Since 2008, the central banks of advanced countries have borrowed trillions of dollars from their commercial banks in the form of interest-paying reserves and invested the proceeds in portfolios of risky assets. We investigate how this new style of central banking affects central banks'...

What set of institutions can support the activity of a central bank? Designing a central bank requires specifying its objective function, including the bank's mandate at different horizons and the choice of banker(s), specifying the resource constraint that limits the resources that the central...
