Stock Prices, News, and Economic Fluctuations

Open access
Beaudry, Paul, Portier, Franck·2006·American Economic Review

Abstract

We show that the joint behavior of stock prices and TFP favors a view of business cycles driven largely by a shock that does not affect productivity in the short run – and therefore does not look like a standard technology shock – but affects productivity with substantial delay – and therefore does not look like a monetary shock. One structural interpretation for this shock is that it represents news about future technological opportunities which is first captured in stock prices. This shock causes a boom in consumption, investment, and hours worked that precedes productivity growth by a few years, and explains about 50 percent of business cycle fluctuations.

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.
