  • Spending responses including durable purchases are estimates of the MPX, which will exceed estimates of the MPC.

    “Spending responses including durable purchases are estimates of the MPX, which will exceed estimates of the MPC (Laibson et al., 2022).”

    From Student Loan Forgiveness (2025) · cites this paper as Laibson et al., 2022

    Section 4.1 (p. 16) says the MPX will typically be greater than the MPC because durable expenditure is front-loaded relative to durable consumption. Section 4.2 (p. 17) adds that the MPC converges to the MPX over longer horizons. The claim correctly identifies spending responses including durable purchases as MPXs, but its unqualified 'will exceed' overstates the paper's qualified comparison. (LLM, conf=0.86)

    Experimental — accuracy not yet measured

  • Consumption and spending can differ dramatically when households respond by making expensive durable purchases.

    “When considering consumption responses, an important distinction is the difference between consumption and spending, which can differ dramatically when households respond by making expensive durable purchases.”

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.
