Long-run effects of earlier voting eligibility on turnout and political involvement [pdf] cite
The Journal of Politics, 2024
with Daniel Kuehnle and Markus Wagner

Theories of habit formation and transformative voting posit that voting has long-run consequences for turnout and political involvement, with younger voters possibly experiencing more pronounced effects from earlier eligibility. Long-term evidence of the effects of becoming eligible to vote at a younger age remains scarce. We use rich, long-term panel data from the UK to examine the effects of earlier voting eligibility on turnout and political involvement. By leveraging the election eligibility cut-off in a regression discontinuity design, our precise estimates document that earlier eligibility results in contemporaneous increases in several measures of political involvement. However, these short-term effects fade away quickly and do not translate into permanent changes in turnout propensity or political involvement. Our results imply that, in a setting with low institutional barriers to vote, the persistent and transformative effects of being eligible to vote at a younger age are short-lived at most.Replication package (Repository)Twitter thread

Immigration, Female Labour Supply and Local Cultural Norms [pdf] cite
The Economic Journal, 2024
with Sophia Schmitz and Felix Weinhardt

We study the local evolution of female labour supply and cultural norms in West Germany in reaction to the sudden presence of East Germans who migrated to the West after reunication. These migrants grew up with high rates of maternal employment, whereas West German families mostly followed the traditional breadwinner-housewife model. We find that West German women increase their labour supply and that this holds within households. We provide additional evidence on stated gender norms, West-East friendships, intermarriage, and child care infrastructure. The dynamic evolution of the effects on labour supply is best explained by local cultural learning.

A Glimpse of Freedom: Allied Occupation and Political Resistance in East Germany [pdf] cite
American Economic Journal: Applied Economics, 2023
with Luis R. Martínez and Guo Xu,  covered at Marginal Revolution and National Affairs Blog. BSE Insights summary 

This paper exploits the idiosyncratic line of contact separating Allied and Soviet troops within East Germany at the end of WWII to study political resistance in a non-democracy. When Nazi Germany surrendered, 40% of what would become the authoritarian German Democratic Republic was initially under Allied control but was ceded to Soviet control less than two months later. Brief Allied exposure increased protests during the major 1953 uprising and reduced Communist support during the last free elections of 1946. We use novel survey data to argue that even a “glimpse of freedom” can foster civilian opposition to dictatorship. Replication package  (Repository)Endorsement by 'The Hoff' for the publication Twitter thread
There is growing agreement among parents in high-income countries that having a working mother does not harm a preschool child. Yet, research is ongoing on what the long-run effects on children are of being looked after at home (primarily by their mothers) or in child care. Most studies find positive effects of child care on child outcomes for children from disadvantaged backgrounds and moderate effects for children from more advantaged backgrounds. The effects of maternity leave expansions on child outcomes depend on the type of counterfactual care and after the first six months, hardly any beneficial effects on children can be found.  Parents in many cases are able to compensate for reduced time with their children when they are in child care with increased engaged parenting time when they are home with them. A shortage of day care workers in many settings has led to a resurgence of maternity leave expansions and cash-for-care schemes. Policy makers need to improve compensation and the working environment for the sector if a high-quality level is to be achieved and if the beneficial effects on children from especially disadvantaged backgrounds and gains in terms of gender equality are to be maintained.

Culture, Children and Couple Gender Inequality [pdf] cite      
European Economic Review, 2022

This paper examines how culture impacts within-couple gender inequality. Exploiting the setting of Germany’s division and reunification, I compare child penalties of East Germans who were socialised in a more gender egalitarian culture to West Germans socialised in a gender-traditional culture. Using a household panel, I show that the long-run child penalty on the female income share is 23.9 percentage points for West German couples, compared to 12.9 for East German couples. The arrival of children also leads to a greater increase in the female share of housework and child care for West Germans. I add to the main findings by using time-use diary data from the German Democratic Republic (GDR) and reunified Germany, which provides a rare insight into gender inequality in the GDR and allows me to compare the effect of having children in the GDR to the effects in East and West Germany after reunification. Lastly, I show that attitudes towards maternal employment are more egalitarian among East Germans, but that the arrival of children leads to more traditional attitudes for both East and West Germans. The findings confirm that socialisation has a strong impact on child penalties and that family policies may have an impact on gender inequality through social learning in the long run.Replication package Twitter thread

The gender division of unpaid care work throughout the COVID-19 pandemic in Germany  [pdf]  cite
German Economic Review, 2022
with C. Katharina Spiess, Sevrin Waights and Katharina Wrohlich 

The COVID-19 pandemic and related closures of day care centres and schools significantly increased the amount of care work done by parents. There has been much speculation over whether the pandemic increased or decreased gender equality in parental care work. Based on representative data for Germany from spring 2020 and winter 2021 we present an empirical analysis that shows that although gender inequality in the division of care work increased to some extent in the beginning of the pandemic, it returned to the pre-pandemic level in the second lockdown almost nine months later. These results suggest that the COVID-19 pandemic neither aggravated nor lessened nequality in the division of unpaid care work among mothers and fathers in any persistent way in Germany.Replication package Twitter thread

Centre-Based Care and Parenting Activities  [pdf] cite
Oxford Bulletin of Economics and Statistics, 2022
with C. Katharina Spiess and Sevrin Waights 

We examine the relationship between parenting activities and centre-based care using time diary and survey data for mothers in Germany. While mothers using centre-based care spend significantly less time in the presence of their child, we find that differences in the time spent on specific activities such as reading, talking, and playing with the child are relatively small or zero. The pattern of results is more pronounced for lower education mothers. The lack of large decreases in activities is explained by two factors: (i) that centre care replaces time that parents spend with the child but are doing other things such as housework or leisure (a small direct effect), and (ii) that evenings become relatively more activity-rich (a compensating indirect effect). For the intensive margin (full-day vs. half-day), we find more additional reductions in parenting activities, but these are compensated for by lower education mothers during non-centre hours. Our findings represent novel evidence that activities in the home environment are a complement to centre-based care, highlighting a credible additional mechanism for child development effects of centre-based care.
Labor markets in low- and middle-income countries are characterized by high levels of informality. A multitude of interventions have been implemented to increase the formalization of firms and workers, including information campaigns, simplified registration procedures, reductions of payroll taxes, and interventions enforcing formalization. We compile a database of 170 impact estimates from 38 academic studies that evaluate empirically one or more of these formalization interventions. The quantitative analysis correlates the impact estimates of the studies — given as a measure of sign and statistical significance, the effect size or percent impacts — with explanatory factors such as intervention type, outcome variable, scope of the intervention, and contextual factors such as study design and economic context. Several key findings emerge: first, tax incentives are a particularly effective intervention type, and information interventions constitute an important component to combine with other interventions. Second, the outcome "worker registration" shows significantly better results than other outcomes. Third, large-scale policies are more effective on average than singular programs. Fourth, interventions tend to be more effective in a more promising (labor) market context.

Understanding Day Care Enrolment Gaps [pdf] cite
Journal of Public Economics, 2020
with Sevrin Waights and Sophia Schmitz 

We document gaps in day care enrolment by family background in a country with a universal day care system (Germany). Research demonstrates that children of parents with lower educational attainment and children of migrant parents may benefit the most from day care, making it important to understand why such enrolment gaps exist. We use a unique data set that records both parental demand for day care and actual usage to investigate determinants using complementary decomposition and quasi-experimental analyses. Our decomposition shows that (a) differences in demand are important but do not fully explain the enrolment gaps, (b) large shares of the gaps are unexplained, especially for migrant parents, and (c) the heterogeneous effects of access barriers (shortages and fees) may explain some of the remaining gaps. Our quasi-experimental design finds that reducing shortages significantly decreases the enrolment gap by parental education but not by parental migrant status. Similarly, using the synthetic control method we show that a reduction of fees reduces only the gap by parental education. We discuss implications for policy. 
Before 2006, large firms in Germany were obliged to pay for the generous maternity protection of female employees, such that firms’ expected costs depended on employees’ gender and age. From 2006 onward, all firms paid for maternity protection by contributing to the statutory health insurance system, where the contribution depends only on the number of employees and their wages and is thus independent of gender and age. This had been the regulation for small firms already before the reform. Using data from linked employer-employee administrative records, we provide evidence that the reform was followed by an increase in female relative wages within large firms. This reform effect provides evidence for statistical employer discrimination in the pre-2006 setup.
