Marinova, Dani M. & de Carvalho, Gabriela. “De-penalizing motherhood? Paternity leave’s (un)intended effects on job discrimination.”

Abstract Job discrimination associated with motherhood has been documented across advanced capitalist economies, but we know little about the effectiveness of father-specific leave intended to redress it. Paternity leave seeks to increase and normalize men’s involvement in caregiving, challenge traditional gender norms that associate childcare primarily with mothers and reduce employer biases that penalize women for assumed caregiving responsibilities. We test this expectation for the first time by leveraging original survey data on reported discrimination by parents with children born before and after Spain’s 2021 paternity leave reform, which extended paternity leave and equalized it with maternity leave. Spain provides a compelling case to assess paternity leave’s impact, with over 80% of eligible fathers now taking paternity leave, alongside well-documented discrimination against mothers and no penalties for fathers. Results show that the reform did not reduce discrimination against mothers, who report stable rates of job discrimination before and after its implementation. Fathers, however, report significantly higher levels of job discrimination after the reform—especially in relation to hiring, termination, and workplace culture—suggesting that equal leave entitlements trigger new forms of bias against men as caregivers.

Marinova, Dani M. & Bellón, Pedro Manuel. “Paternity Leave and the Motherhood Penalty: How Within-Couple Inequalities Conditions Policy Impact.”

Abstract Motherhood-related labor market penalties remain a major driver of the gender employment gap. Father-specific paternity leave is often promoted as a policy tool to support maternal employment, yet evidence of its effectiveness is inconclusive. This article examines whether—and under what conditions—paternity leave reduces key dimensions of the motherhood penalty, including the timing of return to work, the terms of labor market reentry, and perceived professional sacrifice. We use original survey data from 1,800 mothers whose children were born before and after Spain’s 2021 paternity leave reform, which extended and equalized paternity leave to match maternity leave. Multinomial regression models show that equal, non-transferable paternity leave is associated with shorter employment interruptions but does not significantly alter reentry conditions. An important exception is mothers with earnings similar to their partners: they are significantly more likely to return to full-time work after the reform, attesting to the moderating role of intra-household economic equality on policy effects. However, mothers’ perceptions of professional sacrifice remain largely unchanged after the reform. Overall, while father-specific leave can alleviate some aspects of the motherhood penalty, its impact is modest and contingent on household characteristics.

Marinova, Dani M. & Hellwig, Timothy. “Public Responses to the Allocation of Welfare Spending: The Case of Old-Age Pensions”

Abstract A basic premise of research on welfare state spending is that electoral incentives matter, with voters backing program expansion and opposing retrenchment. The evidence supporting this premise is mixed, however, presenting a puzzle. Departing from previous studies, we argue that apparent null effects stem from an emphasis on the generosity of social spending at the expense of its distributional allocation. We argue that citizens’ preferences over the allocation of welfare spending depend on their relationship to economic vulnerability. Individuals in secure economic situations support schemes with benefits proportional to contributions, while those in more vulnerability positions instead favour systems based on recipient need. These heterogeneous preferences translate into public evaluations of policymaker performance, providing a pathway for the electoral connection. We test this argument in two stages: first, using ESS Round 4 to examine how individual precarity shapes preferences for needs-based versus contributory pensions; and second, using the Executive Approval Database to assess how composition of pension expenditures and debt perceptions affect government support across eleven European welfare states (1986–2019). Results in tandem provide evidence consistent with research expectations. By highlighting the micro-level foundations of policymakers’ incentive structures, study results provide a path forward for specifying connections between the allocation of social policy spending and mass politics.

González Motos, Sheila & Marinova, Dani M. “Equal Leave, Equal Care? Evidence from the 2021 Paternity Leave Reform in Spain.”

Abstract This manuscript investigates whether equal and non-transferable paternity leave can promote more equitable caregiving within couples. Exploiting a natural experiment created by Spain’s 2021 paternity leave reform—which established a 16-week leave entitlement equal to maternity leave—we analyze its effects on fathers’ involvement in both physical and cognitive childcare. Drawing on an original two-wave survey of over 3,400 partnered parents of children born between 2018 and 2022, we estimate short- and medium-term impacts of increasing paternity leave duration. Results show modest gains in fathers’ participation in physical care during the early months following birth, but these effects dissipate after return to work. No significant shifts are observed in the distribution of cognitive labor, which remains disproportionately shouldered by mothers. Effects do not vary significantly by birth order or socioeconomic status. Our findings suggest that even under ideal policy conditions—equal, well-paid, non-transferable leave entitlements—progress toward gender-equal caregiving is limited. The study highlights the persistence of traditional gender roles, particularly in mental and anticipatory care tasks, and calls for broader institutional and cultural change beyond parental leave policy.
