We study how changes in the value of the steady-state real interest rate affect the optimal inflation target, both in the U.S. and the euro area, using an estimated New Keynesian DSGE model that incorporates the zero (or effective) lower bound on the nominal interest rate. We find that this...

This paper studies how stable over time are the so-called "structural parameters" of dynamic stochastic general equilibrium (DSGE) models. To answer this question, we estimate a medium-scale DSGE model with real and nominal rigidities using U.S. data. In our model, we allow for parameter...

What stands out in retrospect about U.S. monetary policy during the Greenspan Era is the ongoing movement away from mechanistic restrictions on the conduct of policy, together with a willingness on occasion to depart even from what more flexible guidelines dictated by contemporary conventional...

Changes in both the macroeconomy and in macroeconomics suggest that the IS-LM-AS model is no longer the best baseline model of short-run fluctuations for teaching and policy analysis. This paper presents an alternative model that replaces the assumption that the central bank targets the money...

Aging populations in advanced economies are placing ever-increasing demands on government spending in the form of old-age benefits. Economies that have promised substantially more benefits than they have made provision to finance are heading into a prolonged era of fiscal stress. Unresolved...

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...

Inflation targeting is a monetary-policy strategy that is characterized by an announced numerical inflation target, an implementation of monetary policy that gives a major role to an inflation forecast and has been called forecast targeting, and a high degree of transparency and accountability....

Financial systems are inherently fragile because of the very function which makes them valuable: liquidity transformation. Regulatory reforms can strengthen the financial system and decrease the risk of liquidity crises, but they cannot eliminate it completely. This leaves monetary policy with a...

The paper considers the merits of rules and discretion for monetary policy when the structure of the macroeconomic model and the probability distributions of disturbances are not well defined. It is argued that when it is costly to delay policy reactions to seldom-experienced shocks until formal...
