The Consumption Response to Income Changes
Abstract
We review different empirical approaches that researchers have taken to estimate how consumption responds to income changes. We critically evaluate the empirical evidence on the sensitivity of consumption to predicted income changes, distinguishing between the traditional excess sensitivity tests and the effect of predicted income increases and income declines. We also review studies that attempt to estimate the marginal propensity to consume out of income shocks, distinguishing between three different approaches: identifying episodes in which income changes unexpectedly, relying on the covariance restrictions that the theory imposes on the joint behavior of consumption and income growth, and combining realizations and expectations of income or consumption in surveys in which data on subjective expectations are available.

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.
