This document summarizes a working paper that studies the effects of Luxembourg's 2009 expansion of subsidized childcare access through a universal childcare voucher. The voucher aimed to increase the use of formal childcare and support parental employment. Using a differences-in-differences strategy with longitudinal data, the paper finds that in response to more affordable childcare, maternal employment increased by 4-7 percentage points and hours worked rose by about 3 hours per week. Parents with younger children under age 3 were more likely to use daycare for longer hours, with no change in informal care use, suggesting no crowding out of existing arrangements. The results provide evidence that expanding access to existing subsidized childcare can effectively increase maternal employment, especially
This document summarizes a research paper that investigates the effect of increased availability of public pre-kindergarten programs on maternal labor supply in the United States. Using data from 13 states where school districts are organized at the county level, the author employs a differences-in-differences model to compare changes in labor force participation and employment of mothers with four-year-olds in counties with growing pre-K availability over time, relative to counties without increased availability. The results suggest that greater access to public pre-K is associated with statistically significant increases in labor supply for mothers of four-year-olds, both with and without younger children. Specifically, full implementation of pre-K is estimated to increase labor force participation by

Child labor and schooling in Malawi: Does mother’s employment matter ? by Mic...IFPRIMaSSP
The study investigated the impact of mother’s employment on child labor and schooling in Malawi using the Third Integrated Household Survey (IHS3) dataset. Children aged 5 to 17 were sampled from the dataset and used in the analysis. The study employed the Multi-level trivariate probit model by considering the mothers equation as fixed effects model and the child-level equations as random effects probit models. The results showed that mother’s employment is negatively related to child labor but positively related to child schooling. Another finding was the negative relationship between child labor and child schooling. These results did not change when the model was disaggregated to compare the effects for a boy child and girl child. Based on the results, policy recommendations include promoting female employment programs by the government so that eventually, child labor may decline and schooling may be encouraged.
Child labor is one of the issues receiving much attention from researchers and scholars around the world. Child labor still occurs in most countries around the world. Viet Nam is also one of the countries with relatively high child labor and increasing trend. This article is based on critical discourse analysis and data from the General Statistics Office of Vietnam to analyze some fundamental issues of child labor in Vietnam, thereby giving policy suggestions to the Vietnam government in minimizing the current child labor situation.

Childcare provision is a crucial part of a modern state’s
infrastructure: it enables parents to work, improves
children’s outcomes and helps narrow the gap
between disadvantaged children and their peers. The
importance of childcare is now recognised and over
the last 20 years there have been many policy changes
that have aimed to make childcare more affordable
for families, through free early education, tax credits,

recently, the Government has announced that it will
double the hours of free early education for three and
four year olds, with working parents offered 30 hours

The influence on childhood circumtances on adult health2014Gulbin Erdem
The document discusses the influence of childhood circumstances on adult health. It finds that childhood disadvantage is strongly linked to poorer health outcomes later in life. Studies show that people who experienced socioeconomic hardships during childhood have higher risks of mortality and morbidity from various diseases even when accounting for their adult socioeconomic status. One mechanism believed to link childhood conditions to later health is epigenetics, where early life experiences can modify gene expression. The report recommends greater investment in early childhood interventions as there is strong evidence they can improve health and generate high economic returns through improved outcomes.

This document outlines a dissertation on the socio-economic importance of family day care and its impact on women's employment in Hungary. The dissertation aims to examine how improving access to affordable, flexible day care options could change mothers' negative attitudes towards early child care and increase women's participation in the workforce. The theoretical model discusses factors influencing women's employment decisions, including social norms, employer attitudes, state policies, and availability of child care arrangements like family day care centers. The dissertation will analyze literature on socialization, child development, and parental preferences to understand perceptions of early child care and explore how restructuring state aid could better support working mothers in Hungary.

The document discusses challenges in conducting cross-national research on socioeconomic status (SES) and child development. It is difficult to find truly comparable measures across countries due to differences in how data is collected. The researcher discusses how they addressed this by selecting common SES measures like income quintiles and harmonizing variables to prioritize comparability over using country-specific measures. Their research found SES gaps in school readiness vary between countries and that most factors like these are already present before school entry, especially in the US. The researcher advocates being transparent about harmonization decisions and how sensitive results are to alternative measurements.

Statistical gender discrimination: evidence from young workers across four de...GRAPE
Statistical discrimination at young age due to fertility expectations may decrease as the average age of first birth increases. The authors analyze data from 56 countries over four decades to test whether changes in the timing of fertility are linked to changes in adjusted gender wage gaps for labor market entrants aged 20-30. They estimate adjusted gender wage gaps and instrument for fertility timing using reforms to compulsory education, military conscription policies, and the authorization of contraceptive pills across countries over time.

This was a Project we took in our Econometrics course with Prof. Hemanshu Kumar in the Spring 2018 Semester. Using Regression with STATA, we attempted to establish a causal relationship between gender equality and economic growth.
What are the welfare and macroeconomic effects of family policies? How do they depend on policy composition? I answer that questions in overlapping generations model calibrated to the US. I account for the idiosyncratic income risk, redistribution via social security, and tax and benefit system. I explicitly model child-related tax credit, child care subsidies, and child allowance. I show the expansion of the family policy yields higher welfare. The expenditure on the optimal policy accounts for approximately 3% of GDP. Even though the optimal family policy is three times bigger than the status quo policy, taxes decrease when the optimal policy is implemented. Therefore, reform is self- financing. The structure of family policy is crucial for welfare evaluation. Tax credit and child allowance generate higher welfare gains than child care.
This document summarizes key findings from cohort studies in Jamaica that informed public health policies and programs. It discusses how research on:
1) Maternal and child health issues like syphilis screening and hypertension identified needs for more efficient testing and maternal education.
2) Child development factors like poverty, parenting, violence exposure, and nutrition informed policies addressing early intervention, parenting programs, and healthy lifestyles.
3) Educational factors such as screening, early childhood standards, and gender differences guided teacher training and childhood programs.
The success of translating this research relied on engagement with government, clear communication of implications, and researcher involvement in guiding policy implementation.

Statistical discrimination at young age:
This document discusses statistical discrimination based on fertility plans and childbearing. It motivates studying gender wage gaps among young labor market entrants and how delayed fertility may impact these gaps. The authors aim to test the link between the timing of fertility and adjusted gender wage gaps using individual-level data from 56 countries over four decades. They employ instrumental variable strategies using reforms to compulsory education duration, changes to military conscription, and the authorization of contraceptive pills across countries.
1) Young Danish women expect to balance full-time work and family life due to changing social norms and welfare benefits like paid parental leave.
2) The Danish welfare system allows for a year of paid parental leave and subsidized daycare which has led to 75% of Danish women working outside the home.
3) However, the financial crisis has threatened these supports with more pregnant women and parents on leave being fired and some choosing shorter leaves or alternative childcare due to concerns about job stability.
Child-related transfers: is there a room for welfare improvement?GRAPE
How does income risk affect the optimal size of the child-related transfer system? I answer this question in an overlapping generations model with endogenous fertility and PAYG social security. I show that the optimal size of the child-related transfer is increasing in income risk.
First, in the stylized model, I provide the intuition behind this result. Second, I quantify the size of welfare gains due to child-related transfer reform in a full-fledged model calibrated to the US economy.
Expansion of child-related transfer yields to welfare gain even with constant income dispersion. In a scenario with higher income dispersion, welfare gains increase from 1.08% to 1.2% of lifetime consumption.
Third, I show that in a scenario with high-income dispersion, even higher welfare gains may be obtained if the child-related transfer system has a more redistributive nature.
The employment rate of married women with and without pre- school children varies substantially across countries. To what extent can child-related transfers account for this variation? I develop a life-cycle model in which married couples jointly decide their labor supply, female human capital evolves endogenously, and some couples have access to grandparental childcare. I show that child-related transfers can explain most of the variation in the employment rates of married women, even after taking the labor income tax treatment and cross-country variation in childcare fees into account.

This document reviews international research on the impact of early childhood education and care (ECEC) on child development. It finds that high-quality ECEC is associated with benefits for children's development, especially for those from disadvantaged backgrounds. However, low-quality care can sometimes have negative effects. While research on preschool-aged children is consistent, evidence for younger children is more mixed, with some studies finding positive effects and others finding negative or null effects, depending on factors like quality of care and family background. The document provides a comprehensive overview of research from different countries and programs, finding both individual and societal benefits from high-quality ECEC.
IB Diploma Geography Case Study Pro-Natal Policy Of SingaporeJamie Boyd
The pro-natal policy of Singapore was introduced in 1987 to address declining fertility rates since the 1960s that threatened economic and social stability. The policy provided incentives like cash bonuses for having additional children and parental leave. It was enhanced in 2000 with increased bonuses for second or third children. Evaluations in 2004 and 2008 led to amendments like tax relief and subsidies to make the policy more effective. While the policy achieved its goal of stabilizing population growth, concerns remain around environmental sustainability and coercive aspects of population control.
Geert Driessen (2019) Are the early childhood education claims valid?Driessen Research
Early Childhood Education (ECE) often is part of a broader educational disadvantage policy and offers institutional compensatory programs to young children who lack specific educational stimulation in the home environment. ECE typically aims on children from deprived socioeconomic backgrounds and those of immigrant origin. Although ECE nowadays is widespread and accepted as perhaps the most important means of preventing and combatting educational disadvantage, the controversy surrounding the evidence of effects and thus the justification and foundation of ECE provisions still is not solved. This article focuses on the basis (or lack of it) of ECE in the Netherlands.
The document calls for governments in Central and Eastern Europe and Central Asia to end the practice of placing children under three years of age, including those with disabilities, in institutional care. It cites extensive evidence that institutionalization has severe negative impacts on child development, especially for very young children. It urges governments to prioritize family-based care and community services instead of institutionalization as the default placement for vulnerable children. The document outlines specific legislative, budgetary, capacity-building and partnership measures that governments should implement to reform child welfare systems and protect the rights and well-being of children.
The document discusses early childhood inclusion in the United Kingdom. It provides background on the development of policies and services to support early intervention and inclusion of children with special educational needs. Key policies and initiatives over the last 20 years aimed to provide universal early childhood services alongside targeted support for children with disabilities or delays. Recent reforms place families at the center of planning and emphasize coordinated support across education, health and care services from birth to age 5. The document also describes current early childhood inclusion practices in the diverse range of settings in the UK.
Increasing numbers of parents do not have a standard nine-to-five job; they may work shifts, have zero-hour contracts, unforeseen overtime or other unpredictable hours. These atypical work patterns can present childcare challenges, if partners or relatives cannot provide informal childcare. Two of our reports examine the scale of these challenges and present solutions to help meet this specific childcare need.

This study examines the causal effect of child labor on later socioeconomic outcomes using panel data from Vietnam. The authors find that children who worked as children are significantly less likely to be in school and have lower educational attainment five years later. However, these same children have a greater probability of wage employment and higher earnings as young adults. The authors estimate that the earnings gain from work experience exceeds the foregone earnings from reduced schooling, suggesting the net effect of child labor may be positive, at least until early adulthood. Over the longer run, the returns to education are found to increase more than the returns to child labor experience.
UNICEF and OHCHR call on governments in Europe and Central Asia to end the practice of placing children under three years old, including those with disabilities, in institutional care. While reforms have been ongoing, the rates of institutionalization in the region remain extraordinarily high, with over 600,000 children living in institutions. Placement of young children in institutional care should only be used as an absolute last resort and for short term emergencies of no more than six months. It is time to prioritize developing family and community-based care alternatives to support vulnerable families and children, especially those with disabilities.
Grandparents in Europe- what is the impact on grandparents of their caring?Grandparents Plus
Results of EU wide research on grandparents which aims to:
To investigate patterns of grandparent health and wellbeing and their relationship to socio-economic, demographic and caring roles (both for children and adults).
To examine how cumulative advantage/disadvantage across the life course (e.g. in terms of childhood, work, partnership, health and/or housing trajectories), in addition to socio-economic and demographic characteristics, is associated with grandparent health and wellbeing. (value of life histories from age 16)
To investigate how variations over time in grandparent childcare, and other socio-economic and demographic factors affect grandparents’ own health and wellbeing. We will examine how socio-economic status at each wave interacts with grandparent childcare to affect grandparents’ own health and wellbeing.
For example, does grandparent childcare have a deleterious effect on health and wellbeing but only for those in the most vulnerable groups and at the highest care intensities?
Does grandparental involvement at lower intensities have a beneficial impact on health and wellbeing?
An additional year of schooling is associated with a 0.107 higher probability of not having a chronic illness for adults in Mongolia. For males it's 0.114 and for females it's 0.100. A mother's additional year of schooling increases the probability her child does not have health complaints by 0.031. However, a father's schooling has no impact on a child's health. While education is linked to better health outcomes, the causal mechanisms are still being investigated.

This document provides a report card on how family friendly the UK is based on analysis of policy, statistics, and a survey of parents. It examines how families are faring in terms of income and poverty, employment, and public services like education, healthcare, and social care. While most parents are satisfied with public services, many families feel the financial squeeze of stagnant wages and rising costs of living. Access to affordable childcare, flexible work opportunities, and extra-curricular activities are identified as areas needing improvement to better support families.
The document discusses the increasing focus in UK policy on early childhood development and parenting interventions. It outlines how New Labour and the Coalition government have promoted the idea that parenting skills can be taught and that certain parenting styles are evidence-based. Major reviews on early intervention recommended universal parenting programs, early education from birth, and regular assessments of preschoolers' social-emotional skills.

This document summarizes a student paper that examines the effect of mandated paid maternity leave on fertility rates in 10 OECD countries from 1970 to 2012. The student uses regression analysis with panel data to analyze the relationship between paid maternity leave and fertility rates while controlling for other factors. The analysis includes regressions with different lag periods to account for delayed effects of policy changes. The results in the four tables in the Appendix show that mandated paid maternity leave has no statistically significant effect on fertility rates.
This study examines the relationship between teen motherhood, education, and employment outcomes in the Philippines. It finds that education mediates the impact of teen motherhood on work status and type, as teen mothers have lower odds of completing high school and higher education, and thus lower odds of obtaining favorable work. Specifically, finishing high school increases the odds of non-precarious employment, while higher education increases the odds of employment and quality jobs. The study recommends expanding support for teen mothers to improve access to education and employment opportunities.
This document summarizes a study that analyzes the impact of California's paid family leave program on parental leave use and mothers' wages. The study finds that:
1) The use of parental leave increased significantly for mothers, around 4-5%, but had a small impact on fathers' leave use, increasing only around 1%.
2) Placebo tests found no significant impacts on other states, supporting that the increases in California were due to the paid family leave program.
3) The increases in leave use were larger for disadvantaged groups like unmarried and black mothers compared to advantaged groups.
4) The study also examines the impact on mothers' wages but does not provide results in this summary
This document discusses the economic benefits of investing in early childhood care and education. It summarizes research showing investments in children's early years have higher rates of return than later investments due to the rapid development of skills like self-control in early childhood. Quality early education improves educational and employment outcomes. It enhances children's cognitive and non-cognitive skills, leading to higher earnings. Early education also reduces child poverty by supporting child development and enabling parental employment. The document argues the economic case for increased government investment in early childhood is compelling based on its long-term benefits.
This document is a dissertation submitted by Nathan McGibney for a Masters in Development Practice examining child labor in Rwanda through qualitative research. The literature review discusses debates around defining and measuring child labor, unpaid household services (UHS), and how dominant data collection fails to capture the full reality of children's work in informal and domestic contexts. It finds UHS burden girls more and notes labor's complex impacts on education. Qualitative research in Rwanda revealed children's intensive exploitative labor evading recognition due to private/informal settings and lack of context-specific definitions.

HijackLoader Evolution: Interactive Process HollowingDonato Onofri
CrowdStrike researchers have identified a HijackLoader (aka IDAT Loader) sample that employs sophisticated evasion techniques to enhance the complexity of the threat. HijackLoader, an increasingly popular tool among adversaries for deploying additional payloads and tooling, continues to evolve as its developers experiment and enhance its capabilities.
In their analysis of a recent HijackLoader sample, CrowdStrike researchers discovered new techniques designed to increase the defense evasion capabilities of the loader. The malware developer used a standard process hollowing technique coupled with an additional trigger that was activated by the parent process writing to a pipe. This new approach, called "Interactive Process Hollowing", has the potential to make defense evasion stealthier.

Abstract
In most OECD countries, subsidised childcare is a key instrument to support
maternal employment. Using a large reform implemented in Luxembourg
in 2009, I study the effect of expanding access to subsidised childcare on
childcare and employment decisions of women in a context where childcare
is universal and heavily subsidised, but bound by capacity constraints. The
identification relies on temporal variation across child age groups. The re-
sults show that, in response to the reform, the employment rate of mothers
increased by 4-7 percentage points and their hours of work by around 3 hours
per week. Studying heterogeneous effects reveals a differential impact of the
reform for more vulnerable mothers. Parents whose youngest child is under
the age of 3 are found to use more daycare services, for longer hours, while
the use of informal care remains unchanged. These results suggest that there
is no crowding out effect of the new policy.

4. 1 Introduction
Over the last decades, improving access to affordable Early Childhood Education and Care
(ECEC) services has been a key policy in many OECD countries. Policy makers have based
their policy on the belief that early childhood education and care policy can be a tool to recon-
cile work and family life, and thus support maternal employment and reduce gender inequal-
ities (OECD, 2018). However, empirical evidence on the effectiveness of childcare policy to
support maternal employment are mixed across countries and time. Answering this question is
of critical importance for countries who are currently expanding childcare policy, by increas-
ing the amount of subsidies, the number of free hours of care or the group of eligible children.
For example, between 2000 and 2013, most states in West Germany adopted a free childcare
policy. In 2017, in the UK, the number of free hours of childcare for 3- to 4-year-old was
doubled from 15 hours to 30 hours per week for working parents. Also in 2017, Luxembourg
started providing 20 hours of free daycare for all children between 1 and 4 years old. More
recently, Japan decided to introduce a free daycare policy for children under the age of 5 in
Autumn 2019.
This paper investigates the impact of a recent policy that increases the availability of af-
fordable childcare in Luxembourg at a time when public childcare was universal and heavily
subsidised, but with limited places. In 2009, the government introduced a childcare voucher.
The childcare voucher is universal: all children under 13 years old are eligible, regardless of
family’s income and parent’s job. The childcare voucher aimed at increasing the use of formal
childcare (including before and after school care), helping parents to find a work-life balance
and reducing socio-economic inequalities between children. The childcare voucher reform
increased government’s subsidies to childcare facilities. New providers entered the market,
increasing the overall provision of subsidised childcare: the number of slots doubled between
2009 and 2014 (source: Ministry of Family, Ministry of Education, Luxembourg). Employing
a Difference-in-Differences strategy, I estimate the effect of the reform on child and maternal
employment outcomes using longitudinal data from the European Union - Statistics on Income
and Living Conditions (EU-SILC) survey for the period 2004-2014. The treatment group con-
sists of women aged 20 to 50 years old with a youngest child up to 13 years old. As a control
group, I choose to use women of the same age group but whose youngest child is 13 years old
or more, and childless women as the trends in outcomes are very similar before the reform. I
provide graphical evidence, placebo estimates and tests on pre-reform difference in slopes to
make sure that eligible mothers and non eligible mothers are comparable. I also exploit the
difference in the intensity of the policy change between children’s age over time as the increase
in the number of places at childcare facilities was more pronounced for younger children than
for older ones.
This setting has many interesting features. Firstly, I provide evidence on the effects of
expanding access to existing subsidised childcare whereas much of the literature focuses on
the role of the introduction of subsidised childcare or preschool programs for children up to
three years old. Results from this literature may not be transferable to the case where ex-
isting subsidised childcare is expanded for different reasons. On the one hand, the contexts
regarding maternal employment and childcare attendance are different. Likely, the group of
women who might be sensitive to the incentives given by childcare policies differs from the
group of women who might respond to the introduction of such policy. On the other hand,
the impact found for parents of preschoolers may be different than the impact found for par-
ents of younger children, mainly because preferences for childcare arrangements vary with
2
5. the age of the child. In contrast to most of the literature focusing on mothers’ of preschool
children, I provide evidence for mothers of children under the age of three. Provision of sub-
sidised childcare for this age group is important for several reasons. From the mother’s side, a
poor provision of affordable childcare services may lead to withdraw from the labour market,
with negative effects on future earnings potential. There is large evidence documenting the
cost of motherhood on women’s careers (Waldfogel, 1998, Lundberg and Rose, 2000, Sigle-
Rushton and Waldfogel, 2007, Fitzenberger et al., 2013, Goldin, 2014, Angelov et al., 2016,
Adda et al., 2017, Blau and Winkler, 2017, Rossin-Slater, 2018). From the child’s side, the
period 0-3 years is recognised as a sensitive period because early developmental outcomes
may predict economic success later in life and interventions made in the early period of life
may have higher return rate than later on interventions (Cunha et al., 2005, Mueller and Plug,
2006, Almond and Currie, 2011, Lindqvist and Vestman, 2011). Thirdly, the childcare voucher
introduced in Luxembourg benefits all children less than 13 years old, regardless of family’s
income and parent’s job. While most of the evidence relies on programs targeted at subgroups
of the population, I can analyze the effect of the policy on the overall population which is of
high interest for policy makers, as well on specific sub-groups.
The results indicate that the employment probability of women whose youngest child is
under the age of three increased by 4-7 percentage points and the hours of work (including
those who were not working before the reform) increased by around 3 hours per week. There is
also evidence of heterogeneous responses, with more vulnerable mothers (less well educated,
non-natives and single mothers) are found to be more responsive to the reform than the overall
sample. In response to the expansion of subsidised places, parents whose youngest child is
under three years old are more likely to use daycare, for longer hours, while their propensity
to use informal care is unchanged, suggesting no crowding out effect of the new policy. The
results confirm that in a context where employment of young mothers and daycare attendance
were low, making affordable childcare more widely available is a way to increase the use of
daycare and maternal employment. A back-to-envelope calculation suggests a 0.17 percentage
point increase in the employment rate of mothers of a child aged 0-2 per percentage increase
in daycare attendance rate.
This paper relates to a large literature in economics investigating the impact of the provi-
sion of subsidised childcare on maternal employment. The most recent papers exploit policy
changes that provide exogenous variations in prices or access to childcare to identify the effect
of lower childcare prices or higher access to outside household childcare on child and mater-
nal outcomes. Most studies focus on preschool children (3-6 years old) and provide mixed
empirical evidence. Some authors find positive and sizable effect of public childcare on ma-
ternal employment (Baker et al., 2008, Berlinski and Galiani, 2007, Lefebvre and Merrigan,
2008, Herbst, 2017, Cascio, 2009, Lefebvre et al., 2009, Nollenberger and Rodriguez-Planas,
2015). By contrast, other authors report small, if any, effects, which are applicable to specific
sub-groups of mothers, such as single mothers or less-well educated mothers (Gelbach, 2002,
Fitzpatrick, 2010, 2012, Goux and Maurin, 2010, Hardoy and Pal, 2013, Felfe et al., 2015,
Givord and Marbot, 2015). Small effects are found when the reform leads to only marginal
decreases in the costs of childcare (Lundin et al., 2008), in contexts of already high female
employment and childcare attendance simply because the scope for policies is limited. Small
to zero effects are also found if newly subsidised places crowd out existing private childcare
arrangements, especially when there is still rationing after expansion (Bauernschuster et al.,
2016, Cascio et al., 2015, Cattan, 2016). From a policy perspective, providing evidence on
the role of policy that expand subsidised childcare is important while, in most OECD coun-
3
6. tries, supporting female employment is a key policy goals and the public expenses devoted to
childcare interventions is growing.
Additionally, my analysis is related to a literature on the effect of the public provision of
private childcare services by a voucher. Proponents of a voucher in the childcare market argue
that vouchers may increase parents’ choices and thus their satisfaction, and may also increase
the quality of childcare by stimulating competition between providers (Bradford and Shaviro,
1999, Steuerle, 2000). But in a context of universal subsidised childcare, a childcare voucher
may lead to non-negligible crowding out effects as the new subsidised childcare may substitute
for private arrangements (Bergstrom et al., 1986). There is empirical evidence that a voucher
increases the use of for-profit daycare by increasing affordable demand and encouraging new
(for-profit) providers to enter the childcare market (Bassok et al., 2014, Warner and Gradus,
2009). This effect is found to be higher in areas that suffered from rationing before the intro-
duction of the voucher (Viitanen, 2011). This paper provides additional evidence on this issue
by investigating the role of a childcare voucher on parental choices in a context of universal
public childcare with excess demand prior the reform.
The paper proceeds as follows. I first describe the institutional context and the 2009 child-
care reform in Section 2. Section 3 and Section 4 respectively presents the data and identifica-
tion strategy. The results, including robustness checks, are presented and discussed in Section
5. Finally, I conclude in section 6.
2 The institutional context and the 2009 childcare reform
In this section, I describe the institutional context in Luxembourg to underline to what extent
my results could be relevant for other countries, before presenting the 2009 reform in question.
In Luxembourg, as in other OECD countries, employment rates are lowest for mothers of
children aged zero to two years, for those with low education, and with a migration background
(see the Appendix). To support working parents, Luxembourg provides paid maternity and
parental leaves and subsidised high-quality public childcare. Paid maternity leave lasts for 16
weeks, of which 8 weeks must be taken by the mother before childbirth. Upon completion
of maternity leave, the childcare options available to working parents are parental leave or
paid care in a daycare centre (public or private), a childminder or unpaid care by relatives.
There are no legal claims for a place. Daycare provision is mixed in Luxembourg: daycare
centres can be either publicly or privately owned. Compulsory schooling starts at the age of
4 in Luxembourg. Most of children start secondary school when they turn 12. At the age of
3, children can enter preschool (’Precoce’), which is not mandatory and provided on a part
time basis by municipality. Around the year of the reform, two-thirds of eligible children are
in ’Precoce’ class (source: Ministry of Education).
Before the 2009 reform, daycare centres were subsidised as long as they satisfied a set of
criteria established by law. These criteria related to the staff-child ratio, the group size, the
education and training of the employees and the characteristics of the facilities. There were
different types of grants (operating costs, equipment/materials, buildings). The price paid by
the parents differed according to the type of provider. In public daycare centres, it was a
function of their income and the birth order of the child. By contrast, private providers were
free to set their own prices.
For many years in Luxembourg, childcare provision rates for children under 3 years of age
were low, below the 33% target agreed at the 2002 Barcelona Summit, and there were waiting
lists. To allocate the available places among families, priority rules were used. In public
4
7. childcare centres, priority rules were derived from family characteristics. In the private sector,
priority rules were not defined by family characteristics: the available slots were allocated
according to the rule ’first come, first served’. In 2007, 61% of public centres refused children
because of limited numbers of places, compared to 29% of private daycare centres (Bousselin,
2017). This difference can be explained by a more important demand for public childcare: the
public sector was more attractive than the private one because, on average, the former provided
childcare at a lower price for a similar (or even higher) quality.
In 2009, the government passed a childcare reform, the so-called childcare voucher, to
promote access to affordable childcare services (either public or private), help parents to find
a work-life balance and reduce socio-economic inequalities between children (Ministry of
Family, 2009). All children under 13 years old or not yet enrolled in secondary education are
eligible. The government subsidises private facilities so that the price paid by parents is the
same as the one they would pay in a public facility. This price, which is considerably lower
than the price which used to be paid before the reform, depends on the family’s income and
children’s birth order. On average, before the reform, the hourly price was 2.50 euros in the
public and 4.90 euros in the for-profit sector, compared to 1.40 euros in both sectors after the
reform.
The new policy acts as a huge boost for new private providers to enter the market, increas-
ing the overall provision of childcare. In particular, the number of places quadrupled in private
daycare and doubled in home-based care. It is not surprising as there are no barriers to entering
the market and the reform increased the number of families who can afford formal childcare.
Thus, private providers have had strong incentives to offer new slots. This increase in the num-
ber of places was much more pronounced for younger children than for older ones: the number
of places for children aged 0-3 have been multiplied by 3.6; those for children aged 4-12 years
old by 1.6 (see Table 1). This increase translates into a growth in daycare attendance (see Table
2). Due to the rise in subsidies and the rise in daycare attendance, the government expenses
on early childhood and education and care rose from 0.42 percent of GDP in 2009 to 0.77 in
2013 (OECD family database). The budget devoted to the childcare policy has tripled over the
period, growing from 87 millions in 2009 to 303 millions in 2015, which is now roughly half
of public spending for family allowances (source: Ministry of Education and National Fund
for Family Allowances).

3 Data
In this paper, I use data from the Luxembourgish household panel survey (EU-SILC/PSELL
3). EU-SILC/PSELL 3 is an annual survey of the population in Luxembourg and the Lux-
embourgish component of the European Union-Statistics on Income and Living Conditions
(EU-SILC). This survey collect timely and comparable cross-sectional and longitudinal mul-
tidimensional microdata on income, poverty, social exclusion and living conditions. While
social exclusion and housing information are collected at the household level, labour, educa-
tion, income and health information are collected at the individual level. The survey has been
used to provide data on and monitor social inclusion and poverty in the European Union.1 The
Luxembourgish survey is representative of the whole population living in Luxembourg and
affiliated to the national Social Insurance.
The main advantage of the EU-SILC/Psell 3 survey for my analysis is that it contains
detailed information on both parents and children. The survey allows me to match women
with their partner and their child(ren) and thus to identify families. Besides information related
to job and hours of work, the survey also collects information on childcare arrangements for
each child below 13 years old living in the household (e.g. the type of childcare and the
intensity of care). This information is vital for studying to what extent making formal childcare
more affordable increases the use of formal childcare and whether the policy change leads to
crowding out effect (e.g. informal care being substituted by formal care). Another advantage
of this data for my analysis is to provide five years of pre-reform data that enable me to do
placebo tests (see section 5). I use the waves 2004-2014. I exclude data from 2003 because the
definition of childcare arrangements is different from the other waves. I select women aged 20
to 50. The final sample is made up of 34287 women.
Outcome variables In the survey, individuals report their employment status over the year
and, if they are working, the number of hours of work. The most frequent status over the
year is used to define the employment status of the individual. I use this information to build
a dummy variable for whether the person is employed. Employed means full or part-time
employment including maternity leave and parental leave. In the survey, the working hours
are by definition only reported by those who work in the labour market. I include the zero
hours of work of mothers who do not work to avoid composition change when I estimate the
effect of the reform on the number of hours of work (Angrist and Pischke, 2009). Related to
change in mother’s labour supply, one can expect change in father’s labour supply. Similarly
to mothers, I also investigate the effect of the reform on employment and hours of work of

Information on the type of childcare (daycare, home-based care, informal care or whether
childcare is provided by a member of the household instead) is collected for all children below
13 years old. If childcare outside the household is used, the parents also report the number of
weekly hours of this type of care. I use this information to build dummy variables for whether
a household uses daycare, child-minder or informal care for child i. Unfortunately, there is no
distinction between public and private daycare in the survey. Nevertheless, I can distinguish
between different type of non maternal care, which will allow me to look at potential crowding
out effects of the newly subsidised slots in daycare. In particular, I am interested in the use of
non-maternal care and the intensity of this usage measured in hours per week. Non maternal
care refers to daycare centre (either public or private), an official childminder and informal care
(care provided for free by a relative or a non relative inside or outside child’s home). Following
what is done in previous literature, I focus attention on the youngest child in the household.
I include the zero hours of non maternal care to calculate the hours of non maternal care to
avoid composition change when I estimate the effect of the reform on the number of hours of
non maternal care.
Control variables I use the age of the mother, a set of three dummies for the level education
of the mother with the omitted category being the lower level of education. Regarding marital
status, I define a dummy variable for being a single mother. Due to the limited number of cases,
I am not able to distinguish between married mothers and cohabiting mothers. I will refer to
married and non married-cohabiting mothers interchangeably throughout the remaining of the
paper. As non natives are important share of the population in Luxembourg, I distinguish
between them: I use the date of arrival in Luxembourg to make a distinction between non-
natives arrived as a child and non natives arrived as an adult. I assume that the first subgroup
is more willing to have migrated with their parents and thus to have more chance to rely
on their parents (or extended family) for informal care than the latter one. It may also be
the case that norms regarding maternal employment and non maternal childcare differ with
respect to the time spent in the host country. I thus create a set of three dummies for the
migration background: native (being the omitted category), non native arrived as a child and
non native arrived as an adult. I also define a dummy for the presence of an inactive adult into
the household to account for potential childcare giver into the household.
Descriptive statistics Table 3 provides a summary of descriptive statistics for the whole
sample separately for the pre-reform period and the post-reform period. The employment rate
of women whose youngest child is under 3 has has increased by 9 percentage points between
the pre-reform (2004-2008) and post-reform (2009-2014) period. This has gone along with an
increase of hours of work (2.5 per week) and an increased of the incidence of part-time among
employed (5 percentage points). Similarly to the whole population in Luxembourg, the share
of non native is high among the group of mothers whose youngest child is under 3 years old:
before the reform, almost half of them are non native; this figure has slightly increased after
the reform. There are no significant changes in the level of education before and after, on the
number of children, neither in the age of their partner and the partner’s probability to work.
The employment probability of mothers whose youngest child is 13 years old or more has
also increased over the period (4 percentage points). Hours of work have slightly increased
(less than 1 hour per week). The incidence of part-time work has also increased (7 percentage
points). The post period sample is slightly older than the before period sample. For those who

that is not surprising given that this sample is getting older and employment decreases with
age.
4 Identification strategy
In this paper, I use a large reform in Luxembourg that provides an exogenous change to the
overall provision of subsidised childcare. The reform was announced in autumn 2008 and im-
plemented quickly after its announcement (1 March 2009). It is plausible to assume that most
of the families were not familiar enough with the reform early enough for the law to lead to
ex ante reactionary behaviours. Also, new facilities needed time to establish and open. I ex-
pect that much of the effect triggered by the reform took place rapidly after its implementation.
Given the uniform roll-out accross the entire country simultaneously, all families with children
of the same age are equally eligible, and I am unable to exploit regional variation in the timing
of the reform (Havnes and Mogstad, 2011a,b, Felfe et al., 2015). Rather, I use the differential
provision between children’s age over time in a standard Difference-in-Differences model.2
To estimate the effect of the reform, I compare the change in outcomes of those affected
by the reform (the treatment group) before and after the reform, using the change in outcomes
of those who are not affected by the reform (the control group) to control for common trend
effects. Parents who are influenced by the change in the provision of subsidised places are
parents whose youngest child is under 13 years old. The change in the provision of subsidised
places differs with regard to children’s age. As explained in Section 2, the increase of the
provision of subsidised places was much more pronounced for children under three years old
than for older ones. I use this difference between children’s age over time to investigate the
effect of the intensity of the treatment. I thus define mothers whose youngest child is 0-2 years
old as the main treatment group whiles mothers whose youngest child is 3-5 years old and
mothers whose youngest child is 6-12 years old are alternatives treatment groups. Mothers
whose youngest child is 13 years old or more are the control group: they do not benefit from
the reform but are otherwise quite similar to the treated mothers. Women without a child, who
are also not affected by the reform, will serve as another control group in a sensitivity analysis.
I use the years 2004-2008 as the pre-treatment years and 2009-2014 as the post-treatment
years. The baseline model is shown by equation (1):
Yit = α +β1(Treati ×Postt)+β2Treati +β3Postt +εit (1)
where Yit is the outcome of interest for individual i in year t, Treati is a dummy variable
which defines the treatment group, Postt is a dummy variable equal to one in the post reform
period. The interaction term (Treati ×Postt enables me to derive an estimate of β1 which is the
coefficient of interest of the childcare policy impact. α is a constant and εit is an error term.
2In preliminary analysis, two matching models were estimated: (i) a propensity score matching model that
implements nearest neighbor matching on an estimated propensity score based on a BIC-selected set of observed
baseline characteristics and (ii) a matching model using Epanechnikov kernel weight and observed baseline char-
acteristics. These matching models are versions of non-parametric Ordinary least squares (OLS) and condition
on a set of variables as OLS. These models match women of a youngest child of a certain age after the reform
with women of a youngest child of a same age before the reform based on similarities in observed characteristics.
Similar results than those of the DiD models presented here are obtained.

12. I can improve further the specification of the model. First, I add a set of individual and
household covariates to equation (1) to control for differences between the treatment and the
control groups. I use age, education and migration background as well as the number of chil-
dren in the household. All these characteristics are important determinant of external childcare
and employment decisions. Second, I also include year dummies to account for time-varying
patterns in the outcomes. This second model is:
Yit = α +β1(Treati ×Postt)+β2Treati +β3Postt +γXi +θYeart +εit (2)
where Xi is a vector of observable characteristics and Yeari is a vector of year dummies.
The key identifying assumption of the model is that the difference between outcomes be-
tween treatment and control mothers would have remained constant in the absence of the
childcare voucher reform. It means that I assumed that there were no unobserved characteris-
tics that may have changed over time and may have affected, in a different way, the outcomes
of the treatment group compared to the outcomes of the control group. This assumption cannot
be tested. However, I take advantage of having 5 years of pre-reform data to check whether
the treatment and control mothers have a similar trend in the years preceding the reform. I
check the plausibility of the common trend assumption in Section 5 by providing graphical
evidence and more systematic support for it by means of placebo tests. An additional threat to
identification is that the reform might affect mothers’ work and childcare decisions before the
implementation of the reform (ex-ante responses). Given that the reform has been set quickly
after its announcement and that there were capacity constraints, there are little scope to ex-ante
responses. Finally, the common trend assumption may be violated if the characteristics related
to employment and childcare decisions within the group of mothers is not stable. In particular,
it may happen if the 2009 reform affected the fertility behaviour since the treatment group is
defined by having a child under 3 years old. As the reform decreases the opportunity cost of a
child, the reform might have a positive effect on birth rate. Table 4 reports fertility indicators
over the period 2004-2014. There is no support for a change in trends after the 2009 reform.
Another concern with the difference-in-differences approach is the correct computation of the
standard errors. In my estimates, the standard errors are clustered at the local level to account
for cross-sectional within-commune dependence (Bertrand et al., 2004). By clustering at the
commune level, I account for correlations within locality and I assume that the standard errors
are not correlated accross communes within regions.3
5 Results
This section presents my empirical findings. Section 5.1 shows graphical evidence on the
common trend assumption and identify a further set of treatment and control groups. Section
5.2 discusses the results obtained from the Difference-in-Differences models for childcare and
employment outcomes. In Section 5.3, I use alternative treatment groups, I discuss the placebo
estimates and I test for differences between slopes of outcomes in the pre-reform period.

5.1 Graphical results
I compare the employment trends of mothers whose youngest child is under 3 years old (main
treatment group), mothers whose youngest child is 3-5 years old and mothers whose youngest
child is 6-12 years old with two potential control groups: mothers whose youngest child is
13 years old or more and women living without a child. Figure 1 plots the employment rate
over the period for each group of women. The left-hand of Figure 1 shows the evolution of
the employment rate of treated mothers compared to that of mothers whose youngest child is
13 years old or more. The employment rate of all groups increased in a similar way between
until 2008, except a stronger increase in 2007 for mothers whose youngest child is 3-5 years
old. Then, for all groups, the employment rate declined with the 2008 crisis. After 2009,
the employment rate of mothers whose youngest child is 13 years old or more flattened out
until 2012 and increased after this point. By contrast, after 2009, the employment rates of
mothers whose youngest child is 0-2 years old and 3-5 years old increased steadily until 2012
and decreased slowly after this point. The evolution of the employment rate of mothers whose
youngest child is 6-12 years old was noisy after 2009. The increase of employment rates
of mothers of young children coincided with the childcare voucher reform in the year 2009.
The right-hand of Figure 1 shows the evolution of the employment rate of treated mothers
compared to the second potential control group which are women living without a child. The
pre-trend in this measure for this control group is similar to that of the treatment groups. There
was an increase in the employment rates in all groups until 2008; after this point, there was
a decrease in the employment rate in all group. After 2009, the employment rates of mothers
increased while that of women living without a child was still decreasing until 2012. Mothers
whose youngest child is 13 years old or more and women living without a child can be used as
control groups as they exhibit quite similar pre-trends to the treatment groups.
Figure 2 shows the evolution of hours of work (including zeros) between 2004 and 2014.
The left-hand of Figure 2 shows the evolution of hours of work for the treated mothers and
for mothers whose youngest child is 13 years old or more. The right-hand of Figure 2 shows
11
14. the evolution of hours of work of treated mothers compared to control group of women living
without a child. From 2004 to 2008, the evolution of this measure for the two control groups
is quite similar to that of the treatment group of mothers whose youngest child is 0-2 years old
and 3-5 years old. Once again, there is suggestive evidence that mothers whose youngest child
is 13 years old or more and women without a child can be used as potential control groups.
One can expect that the effect of the policy change will be different with respect to chil-
dren’s age while the growth of subsidised places varies with children’s age. As an attempt to
investigate the role of the intensity of the treatment in the heterogeneity of the response to the
childcare policy, I now compare the employment trends of mothers whose youngest child is
0-2 and 3-5 years old with that of 6-12 years old (who were less affected by the growth of
subsidised places). Employment pre-trend of mothers whose youngest child is 0-2 years old
and mothers whose youngest child is 6-12 years old are similar. By contrast, the trend in the
employment and hours of work of mothers whose youngest child is 3-5 years old is dissimilar.
Therefore, in the following of the paper, I compare mothers whose youngest child is 0-2 years
old with mothers whose youngest child is 6-12 years old to investigate the heterogeneity of the
response to the intensity of the policy change.
Finally, Figure 3 shows how childcare outcomes evolve over the period for mothers whose
youngest child is under 13 years old. I choose to exclude other women, that is women with
older children and children living without a child. This choice is made to guarantee that the
groups are comparable in terms of their childcare choice. The left-hand of Figure 3 shows
how daycare attendance evolved between 2004 and 2014. The daycare attendance increased
between 2004 and 2009. After 2009, the daycare attendance increased steadily for the group of
mothers whose children is 3-5 and flattened out after 2012. The right-hand of Figure 3 shows
the evolution of the hours of daycare (including zeros) between 2004 and 2014. Until 2009, the
number of hours spent in daycare increased slowly in each group. After this point, the hours
of daycare for mothers whose youngest child is 0-2 years old and 3-5 years old increased until
2012 and flattened out after this point. This increase was stronger for the group with youngest
child aged 0-2 years old. By contrast, the hours spent in daycare for older children increased
slightly after 2008. Therefore, women whose youngest child is 6-12 years can serve as a
control group to evaluate the effect of the childcare voucher reform on childcare decisions.

5.2 Difference-in-differences results
The previous section shows suggestive evidence that mothers whose youngest child is under
three were more likely to work or to work more after the childcare voucher reform. Mothers
whose youngest child is 13 years or more and women living without a child may be good con-
trol groups for a Difference-in-Differences analysis of labour supply as the pre-reform trends
in employment and hours of work are quite similar for all these groups. I complement this
analysis by investigating to what extent the response to the policy varies with the intensity of
the treatment using different treatment groups. To evaluate the effect of the voucher on child-
care decisions, I use a Difference-in-Differences analysis between mothers whose youngest
child is 0-2 years old with mothers whose youngest child is 6-12 years old while they exhibit
similar pre-trends in childcare outcomes.
I use a linear probability model4 with robust standard errors to estimate the model de-
scribed in equations (1) and (2). For each outcome, I run three different regressions. First, I
estimate the baseline specification in column (1), then I add individual and household controls
presented in column (2) and a time trend in column (3).
4Although the childcare arrangement and employment variables are dichotomous, I use a linear probability
model which can be easily estimated via ordinary least squares rather than a logit or probit model. Indeed, the
DiD coefficient (interaction term) is readily interpretable while it is much more complicated with logit or probit.
13
16. 5.2.1 Effect on maternal labour supply outcomes: employment and hours of work
Table 5 reports the results of the Difference-in-Differences estimates for employment and
hours of work when treated mothers are mothers whose youngest child is 0-2 years old. The
treatment effect is the coefficient β1 from Equation 1. The treatment effect is the effect of the
treatment on the treated that is the effect of the childcare voucher on mothers whose youngest
child is 0-2 years old after the implementation of the reform. The first panel of Table 5 present
the effect of the reform when mothers whose youngest child is 0-2 years old are compared
to mothers whose youngest child is 13 years old or more. Panel B shows the effect of the
childcare reform when the control group is women living without a child and Panel C shows
the effect of the reform when the control group is mothers whose youngest child is 6-12 years
old.
The effect of the childcare voucher is positive and significant in all specifications. The
employment rate of mothers whose youngest child is less than 3 years old increased by 4-7
percentage points after the reform. The magnitude of these estimates remains constant after
adding further controls and a time trend (see columns (2) and (3) of Table 5).
Now, I look at the effect of the reform on the hours of work. To avoid change in the
sample composition, I estimate a linear model with the same sample of mothers that I use in
the employment equation. In other words, I estimate Equation (1) with y being the number of
hours of work, potentially zero. I also find a positive significant effect of the childcare voucher
reform on the number of hours of work. In response to the reform, women whose youngest
child is under 3 years old increased their hours of work by around 3 hours per week after the
reform. Results are similar after adding further controls and a time trend (see columns (2) and
(3) of Table 5), while the size of the estimate is reduced.
5.2.2 Effect on childcare outcomes: type of childcare and hours of care
I now assess how the childcare voucher reform affects the childcare arrangements (type of
childcare and weekly hours) of the youngest child in the family. I compare the change in
childcare outcomes of mothers the most affected by the reform (whose youngest child is under
three) before and after the reform, using the change in outcomes of those who are slightly
affected by the reform (mothers whose youngest child is 6-12 years) to control for common
trend effects. I exclude mothers whose youngest child is 4-5 years old to avoid having mothers
that belong to both control and treatment groups over the period. Table 6 reports the results
where the dependent variables are dummy variables indicating whether the youngest child at-
tends daycare, has a childminder or informal childcare (care provided by relatives, neighbours
or friends for free) and the continuous variables measure the average weekly hours of care in
these different types of arrangements.
I find that with the childcare voucher reform, mothers whose youngest children are under
3 years old are more likely to use daycare (+4 percentage points). Controlling for additional
covariates, as well for a time trend, do not change the magnitude of this effect. Previous lit-
erature showed that the newly available places may crowd out existing private places (Havnes
and Mogstad, 2011a) or comparable public childcare arrangements (Fitzpatrick, 2010). I now
look at the impact of the reform on the propensity to use a childminder or informal care (care
provided for free by grand-parents, relatives or friends). Estimates from Table 6 show that the
use of a childminder or informal care is not affected by the reform, suggesting no significant
crowding out effect. However, the effect of childcare subsidies on informal care may go in
opposite direction depending on whether informal and formal care are substitutes (Busse and

18. Gathmann, 2018). On the one hand, for some parents, informal and formal care are substitute
childcare arrangements. The reform has substantially decrease the price of formal childcare,
making it relatively more attractive than in the past. Then, for that group of parents, the use of
informal care may decrease in response to the reform. On the other hand, some parents may
use informal care as a complement to formal care. For that group of parents, the use of infor-
mal care and formal may jointly increase in response to the reform. Likely, the non-significant
effect of the reform found on informal care is actually the sum of two effects that go in oppo-
site direction, suggesting that caution must be taken with the interpretation on the crowding
out effect of the new policy.
Besides the effect on the propensity to use childcare (daycare, childminder or informal
care), I am also interested in the effect on the hours of that type of childcare. I estimate
Equation (1) with average hours of childcare (daycare, childminder, informal care), potentially
zeros, as the outcome variable. The results show a positive impact of the reform on the hours
of daycare, which increased by almost 3 hours per week. The magnitude of this effect is
unchanged after adding further individual controls and a time trend.
After the reform, parents of children under the age of three are thus more likely to use
daycare and for longer hours. As daycare has became cheaper and more widely available with
the reform, parents may have now more incentives to use daycare than in the past. These
results suggest that the voucher policy reach its (primary) goal of increasing the use of daycare
services.
5.2.3 Effect on paternal labour supply outcomes: employment and hours of paid work
The reform has positively impacted mother’s employment and use of daycare. I now investi-
gate if the reform affect father’s employment outcomes. I estimate the model from equation
1 where yi is the employment probability of fathers and their hours of work (including the
zeros), respectively. The treatment group is fathers whose youngest child is aged 0-2 years
old. The control group is fathers whose youngest child is 13 years old or more as the trends in
employment outcomes are similar before the childcare reform (see Figure 4). Table 7 reports
the results of the Difference-in-Differences estimates for fathers. I do not find a significant
effect of the reform on employment of fathers whose youngest child is less than 3 years old.
This result is in line with previous related literature (Bettendorf et al., 2015, Eckhoff Andresen
and Havnes, 2018). There is indeed little empirical evidence on within couple adjustments of
labour supply given estimates of own and cross labour elasticities of married men closed to
zero (Bargain et al., 2014).

21. 5.3 Sensitivity analysis
In this section, I use a further set of treatment groups and I discuss the common trend assump-
tion by means of a standard placebo test and a test of differences in slopes’ outcomes in the
pre-reform period.
Alternative treatment groups Now, I re-estimate the Difference-in-Differences models de-
scribed in equation 1 and 2 using two alternative treatment groups: mothers whose youngest
child is 3-5 years old and mothers whose youngest child is 6-12 years old. Results are sim-
ilar to the baseline results, while the estimates are higher (see Tables 8 and 9). Employment
probabilities of mothers whose youngest child is 3-5 years old increased by 8-10 percentage
points after the reform. They are found to work more hours, by around 3-4 hours per week.
The figures are similar for the other treatment group. The employment probability of mothers
whose youngest child is 6-12 years old increased by 5-10 percentage points after the reform
while their hours of work increased by 3-4 hours per week.

24. Falsification tests The main threat to my identification strategy consists of deviations from
a common trend between the treatment and the control groups in the years preceding the actual
treatment. In Section 5.1, I have showed graphical evidence that the treatment and the control
mothers show similar trends. I now assess more directly the validity of the key identification
strategy of my model (that the treatment and the controls follow the same time trend over
the period, even though they have different characteristics). To do that, I start by estimating a
placebo effect: I shift the introduction of the policy 4 years prior the 2009 reform. Table 10 and
11 show the results for both treatment groups and the control groups. The placebo effects from
these models are insignificant, confirming that there were no systematic differences between
the treatment and the control mothers before the 2009 reform.
In addition, I test whether the slopes of the outcome are different accross the treated and
control groups over time by interacting the treatment variable with year dummies (Pischke,
2005). In equation 1, I include the interactions of the year dummies and the treatment dummy
for the first four pre-treatment years (e.g for the years 2004 to 2007).The interaction for the last
year of the pre-reform period is excluded from the model to avoid the dummy trap. The coef-
ficients of these interaction terms should be non significant if the outcome trends between the
treatment and control groups are similar. Table 12 presents the results of the test of the differ-
ence in differences assumption. While none of the year-treatment coefficients is significantly
different from zero, one can conclude that the difference in differences is not significantly
different between the two groups in the pre-treatment period.5
5I obtain the same results when the treatment group is mothers whose youngest child is 3-5 years old (see
Table 13).

5.4 Heterogeneity of effect for sub-groups
Until now, I have assumed that the effect of the reform on childcare arrangements and maternal
employment is homogeneous. Now, I explore whether the effect of the reform is heterogeneous
across different groups of mothers. Providing estimates of heterogeneous effects is important
given the likely heterogeneity in gains from selecting into childcare and into the labour market
(Cornelissen et al., 2016, Kottelenberg and Lehrer, 2017). For example, for women who were
not working before the reform, the reduction of childcare costs induced by the reform lowers
the reservation wage: a positive effect of the reform on labour market participation may be
expected. For women who were already working before the reform, the effect depends on the
number of hours of work.
Providing estimates of heterogeneous effects is also important for policy-makers’ point of
view since early childhood education and care policy is often used as an instrument to reduce
inequalities between children. Investigating the effect of the childcare policy on vulnerable
sub-groups of families is thus highly relevant. I will also look at heterogeneous response of
the reform on the following subgroup: non native, less educated and single mothers.
To test for heterogeneity in treatment effect across subgroups, I use the baseline model but
I now allow the coefficient of the treatment effect to vary for mothers’ subgroups (Abadie,
2005). The subgroups are defined by prior employment status, education level, migration
background and marital status. In further regressions, I thus estimate the following model:
26
29. Yit = α +β1(Treati ×Postt)+β2Treati +β3Postt (3)
+β4Gi +β5(G×Treati)+β6(G×Postt)
+β7(G×Treati ×Postt)+εit
where Gi is a dummy that defines the sub-group of mothers. The coefficient β7 on the triple
interaction between the dummy for the sub-group of mothers, the treatment dummy and the
post-reform dummy indicates whether mothers in the sub-group react systematically different
to the childcare reform compared to the overall sample of mothers. Table 14 reports the results
for the treatment group being mothers whose youngest child is 0-2 and control group being
mothers whose youngest child is 13 years old or more.
Heterogeneous effects by initial employment status I start by evaluating whether the re-
form has generated different responses with respect to mother’s initial employment status.
Likely, the overall effect found in the previous section hides different responses according
labour market participation and work hours before the reform. I define a dummy variable for
whether the mother is working or not before the reform. Panel A of Table 14 shows the results
of heterogeneous effect of the reform by initial employment status. While the employment
response to the reform is the same irrespective of the initial employment status, the effect on
hours of work is much more important for mothers who were already working before the re-
form than for the overall sample. The hours of work of mothers working before the reform
increase by almost 6 hours per week, which is roughly three times the estimates found for
the overall group of treated mothers. To complement these results, I also look at different
responses according hours of work before the reform. I define a dummy variable whether the
mother was working part-time before the reform (less than 30 hours per week). The sample is
thus restricted to working mothers before the reform. Panel B of Table 14 shows estimates of
a heterogeneous effect of the reform on hours of work by prior part time. I do not find support
for a heterogeneous response on hours of work by prior part time.
Heterogeneous effects by education level, migration background and marital status of
mothers I also analyse whether the reform has led to different response with respect to
mother’s education. To do that, I define a dummy equal to one for education less than sec-
ondary school level. Estimates are reported in Panel C of Table 14. There is no evidence of a
heterogeneous response by mother’s education level. Low educated mothers may have lower
access to subsidised childcare in case of rationing because, for example, they are less able to
cope with waiting lists. In that case, they could be more responsive to the increase of sub-
sidised places than the average mother. To look at this, I estimate Equation 3 with yit being
childcare outcomes. In the model for childcare outcomes (both use and hours of childcare),
the treatment group is mothers whose youngest child is 0-2 years old and the control group is
mothers whose youngest child is 6-12 years old. Table 15 presents the estimates of heteroge-
neous effects of the reform on childcare use. Less well-educated mothers are more likely to
use daycare for their youngest child: this increase is equal to 6 percentage points, which is 2
percentage points more than the increase estimated for the average mother. But they do not
use more hours of daycare than the average mother in response to the childcare reform.
I now look at heterogeneous responses to the childcare reform by migration background.
I define a dummy variable for whether the mother is non native. Panel D of Table 14 shows
27
30. the results. There is no evidence of a heterogeneous response on the employment probability
while the effect of the reform on hours of work is smaller for non natives compared to the effect
found on the overall sample of mothers. When estimating the model for childcare outcomes,
with the control group is mothers whose youngest child is 6-12 years old, I do not find support
for heterogeneous response on childcare use and hours of childcare (see Panel C of Table 15).
Finally, I investigate whether the reform has led to different responses with respect to
mother’s marital status (see Panel E of Table 14). As observed for non natives, there is no
evidence of a heterogeneous response on the employment probability while the effect of the
reform on hours of work is smaller for single mothers compared to the effect found on the
overall sample of mothers. There is also no evidence of a heterogeneous response on childcare
outcomes with marital status (see Panel D of Table 15).
To sum up, there is evidence that hours of work of more vulnerable mothers are more
responsive to the reform than that of the overall sample. In particular, the effect on hours of
work is higher for low educated than for the overall sample while the effect is lower for non
natives and single mothers than for the overall sample.

34. 6 Conclusion
This paper has focused on the role of the expansion of subsidised childcare on childcare ar-
rangements and maternal employment in Luxembourg. I have exploited a recent reform that
has substantially increased the number of subsidised places for children under 3 years of age.
I show that the employment of mothers whose youngest child is under 3 increased by 4-7 per-
centage points in response to the reform while their hours of work increased by around 3 hours
per week. The magnitude of this effect falls within a similar range as effects found in studies
on the role of the expansion of subsidised childcare in the Netherlands (Bettendorf et al., 2015)
or Spain (Nollenberger and Rodriguez-Planas, 2015). Studying heterogeneous effects reveals
a differential impact on hours of work for more vulnerable mothers (less well educated, non-
natives and single mothers). I also show that parents whose youngest child is under three years
old modify the childcare arrangement: they are more likely to rely on daycare, with an average
increase of 3 hours per week. I do not find that parents substitute the new subsidised places to
informal care arrangements, suggesting that there is no crowding out effect of the reform.
This paper contributes to the literature on childcare policy in two interesting ways. The
first contribution is to provide empirical evidence of the impact of the expansion of access to
universal childcare at a time when most of OECD countries are going to (still) improve access
to their early childhood education systems. Since the European Council held in Barcelona
in 2003, and more recently the new strategy for employment EU2020, member states of the
European Union are strongly encouraged to continue providing subsidised childcare in order
to reconcile work and family lives, enhance child development and reduce inequalities among
children. My results are in line with this recommendation as I show that the expansion of sub-
sidised childcare positively affects the use of childcare services as well as the employment and
the hours of work of mothers whose youngest child is 0-3 years old. The second contribution
of the paper is that, while most of the evidence relies on programs targeted at various sub-
groups of the population, the paper analyzed the effect of the policy on the overall population,
which is of high interest for policy makers, as well on specific subgroups.
In Luxembourg, as in most of OECD countries, there are both public and private child-
care providers. As public and private providers are likely heterogeneous in terms of quality,
opening days, opening hours and location, it is highly relevant to account for heterogeneity in
the provision of childcare when analyzing the effect of childcare policy on child and parent’s
outcomes. Moreover, there is little evidence on the effect of government provision in and reg-
ulation of the early childhood care sector on the supply side, e.g. on workers and firms of this
industry. Yet, it is crucial to understand how childcare supply responds to government inter-
vention to understand the welfare implications, including both the consequences for access to
and affordability of the policy. Both are interesting topics for future research.
