RT Journal Article T1 Parental leave system design impacts on its gendered use: Paternity leave introduction in Spain A1 Castellanos-Serrano, Cristina A1 Escot Mangas, Lorenzo A1 Fernández Cornejo, José Andrés AB ObjectiveThe article evaluates the 2007 introduction of nontransferable and fully paid paternity leave in Spain.BackgroundPrevious research has focused on paternity leave reforms, especially in the Nordic and continental countries. This article studies characteristics of the parental leave system design, including transferability, payment, and purpose of different types of leave for mothers and fathers in a Mediterranean country.MethodWe use a quasi-experimental approach based on a sample of heterosexual dual-earner couples with children born before and after the paternity leave introduction. We estimate differences in differences regression models.ResultsThe 2007 reform caused a significant increase in fathers' number of days of parental leave. Most fathers used the whole nontransferable and fully paid paternity leave, but they hardly used transferable or unpaid leave. Mothers used all of these, especially paid leave.ConclusionThe number of nontransferable fully paid days of parental leave provided by law approximates the actual number of days most fathers used.ImplicationsThe policy design matters. A design of equal, nontransferable, and fully paid leave for each parent is necessary for equal use by fathers and mothers—and thus for gender equality in families and work.
