The Fragility of Estimated Effects of Unilateral Divorce Laws on Divorce Rates
Abstract
Following an influential article by Friedberg (1998) on the response of divorce rates to the adoption of unilateral divorce laws, Wolfers (2006) explored the sensitivity of Friedberg’s results to allowing for dynamic response. We in turn explore the sensitivity of Wolfers’s results to variations in estimation method and functional form, and we find that the results are extremely fragile. We conclude first that the impact of unilateral divorce laws remains unclear. Second, we make the methodological point that identification in differences-in-differences research becomes weaker in the presence of dynamics, especially in the presence of unit-specific time trends.

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.
