The Effect of Schooling on Cognitive Skills

Carlsson, Magnus, Dahl, Gordon B., Öckert, Björn, Rooth, Dan-Olof·2015·Review of Economics and Statistics

Abstract

To identify the causal effect of schooling on cognitive skills, we exploit conditionally random variation in the date Swedish males take a battery of cognitive tests in preparation for military service. We find an extra ten days of school instruction raises scores on crystallized intelligence tests (synonyms and technical comprehension tests) by approximately 1% of a standard deviation, whereas extra nonschool days have almost no effect. In contrast, test scores on fluid intelligence tests (spatial and logic tests) do not increase with additional days of schooling but do increase modestly with age.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Carlsson et al. (2015) find that among 18-year-olds, an extra ten days of school instruction increases scores on crystallized intelligence tests by approximately 0.01 of a standard deviation.

    “Even among 18-year-olds (for whom we might expect investment effects to be weaker) an extra ten days of school instruction increases scores on crystallized intelligence tests (synonyms and technical comprehension tests) by approximately 0.01 of a standard deviation.”

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.
