  • The impacts of maternity leave reforms: Evidence from Finland

  • The evolution of the child penalty


Danzer and Lavy (2018) study how the duration of paid parental leave affects children's educational performance using data from PISA. The extension of the maximum duration from 12 to 24 months had no significant effect on average but the authors highlight the existence of large and significant heterogenous effects that vary in sign depending on the education of mothers. The policy increased the scores obtained by sons of highly educated mothers, as measured in standard deviations, by 0.33 in Reading and 0.40 in Science. On the contrary, sons of lower educated mothers experienced a decrease of 0.27 in Reading and 0.23 in Science. In this article, I replicate their study following the appropriate estimation procedure that takes into account that PISA relies on imputation to derive student scores. I show that the estimates of the effects of the parental leave extension become substantially lower and non-significant.
