Abstract

From 1960From -1983, the standard deviation of annual growth rates in real GDP in the United States was 2.7%.From 1984-2001, the corresponding standard deviation was 1.6%.This paper investigates this large drop in the cyclical volatility OF real economic.activity.The paper has two objectives.The first is to provide a comprehensive characterization of the decline in volatility using a large number of U.S. economic time series and a variety of methods designed to describe time-varying time series processes.In so doing, the paper reviews the literature on the moderation and attempts to resolve some of its disagreements and discrepancies.The second objective is to provide new evidence on the quantitative importance of various explanations for this "great moderation".Taken together, we estimate that the moderation in volatility is attributable to a combination of improved policy (20-30%), identifiable good luck in the form of productivity and commodity price shocks (20-30%), and other unknown forms of good luck that manifest themselves as smaller reduced-form forecast errors (40-60%).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
