Intertemporal Substitution in Macroeconomics

Open access

Abstract

Modern neoclassical business cycle theories posit that the observed fluctuations in consumption and employment correspond to decisions of an optimizing representative individual. We estimate three first-order conditions that represent three tradeoffs faced by such an optimizing individual. He can trade off present for future consumption, present for future leisure, and present consumption for present leisure. The aggregate U. S. data lend no support to this model. The overidentifying restrictions are rejected, and the estimated utility function is often convex. Even when it is concave, the estimates imply that either consumption or leisure is an inferior good.

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.
