Research Interests: Monetary policy, central banking: My research deals primarily with central banking and issues associated with the theory of monetary policy. Recent work has focused on the sustainability of forward guidance, worker heterogeneity and the effects of monetary policy.

My vita contains a complete list of my publications.

The fourth edition of Monetary Theory and Policy, MIT Press 2017, available April 2017. Among the major changes in the 4th edition are the addition of a new chapter on the effective lower bound on nominal interest rates and balance sheet policies, discussion of search and matching models of unemployment in Chapter 8 on the new Keynesian model, and an extensive revision of Chapter 9 on the open economy.

Preliminary: Sustainable Forward Guidance, keynote address presented at the Norges Bank Rethinking Inflation Targeting Conference, Oslo, Norway, September 8-9, 2016. In this paper, I ask whether policy makers lacking the ability to commit may, nevertheless, still make credible announcements about future policy. In the standard analytical frameworks often used to study the effective lower bound (ELB) on nominal interest rates, this can never be the case. These frameworks assume that once the ELB episode is over, it never occurs again. Consequently, there is a cost to fulfilling the promise once the ELB episode is over, while there is no future benefit to fulfilling the promise. However, once there is a positive probability of hitting the ELB in the future, the central bank has an incentive to honor its promises. I find that a promise to keep the nominal interest rate at zero after the ELB episode is sustainable, as long as the promise is not for too many periods. In contrast, announcing an inflation rate for the period after the ELB episode is only sustainable for some values of the likelihood and expected duration of future ELB episodes. Presentation slides

Economics, with Joe Stiglitz, W. W. Norton, 2006, 4th ed. (Also available in separate micro and macro splits.) A modern treatment of economics for the introductory student. Exposes students to the basic competitive model, but deals also with the important role of imperfect information and imperfect competition. The macro approach replaces static aggregate demand and supply models of the price level, to which a Phillips curve is then appended, with an integrated framework for understanding inflation and output determination.
