Abstract: We assess whether survey responses to hypothetical policy scenarios can recover actual labor supply responses from policy variation. We study the German Mütterrente, a pension benefit crediting parents for child-rearing, benchmarking against Artmann et al. (forthcoming). Surveying mothers and fathers about a hypothetical reform modeled on that expansion, we find that mothers expect to reduce their labor supply, with an implied marginal propensity to earn of −0.65—close to the quasi-experimental estimate of −0.54. The response is sensible across subgroups, falls mainly on the extensive margin, and spills over to fathers. In the aggregate, spousal predictions match partners’ own reports.
