The remarkable stability of low domestic inflation in many countries requires explanation. In this paper, a number of competing hypotheses are evaluated on a stand-alone basis, and all are found to be inadequate. This includes the view that this outcome has been solely the result of more...

This paper studies an advantage of commitment over discretion when a central bankobserves only noisy measures of current inflation and output, in the context of an optimizingmodel with nominal-price stickiness. Under a commitment regime, if current policy turns outto be too expansionary...

Using a model of island economy where financial markets aggregate dispersed informationof the public, we analyze how two-way communication between the central bankand the public affects inflation dynamics. When inflation target is observable and credibleto the public, markets provide the bank...

This paper provides a stylized choice-thoretic model to analyze optimal monetary policies among interdependent economies. In response to marcoeconomic shocks, policymakers strike a balance between two objectives. The first is to stabilize marginal costs and markups to offset the distortions...

Monetary economics as practiced by central bank modelers has made a great deal of progress in recent years. In a 2002 paper I interviewed research economists at four central banks and surveyed the models in use at those banks. I criticized the models for having lost all touch with statistical...

In a simple New Keynesian model, we derive a closed form solution for the inflationpersistence parameter as a function of the policy weights in the central bank’s Taylorrule. By estimating the time-varying weights that the FED attaches to inflationand the output gap, we show that the...

Inflation rates in a number of OECD follow a common trend over the past four decades: inflation starts out low in the 1960s, rises for a time before peaking in the 1970s or early 1980s, and then falls back to initial levels. This similarity in the behavior of trend inflation suggests that any...

We study several popular monetary models which generate a non-degenerate stationary distribution of money holdings. Across these environments, our principal finding is as follows: a monetary policy that sets long run nominal interest rates to zero (the Friedman rule) does not typically maximize...

Global liquidity expansion has been very dynamic since 2001. Contrary to conventionalwisdom, high money growth rates have not coincided with a concurrent rise in goodsprices. At the same time, however, asset prices have increased sharply, significantlyoutpacing the subdued development in...

Using the Consensus Economics dataset with individual expertforecasts from G7 countries we investigate determinants of disagreement (crosssectionaldispersion of forecasts) about six key economic indicators. Disagreementabout real variables (GDP, consumption, investment and unemployment)has a...
