First generation elite: the role of school networks,                      Revised and resubmited at the American Economic Review

Joint with Kjell Salvanes and Emma Tominey

Abstract: High school students from non-elite backgrounds are less likely to have peers with elite educated parents than their elite counterparts in Norway. We show this difference in social capital is a key driver of the high intergenerational persistence in elite education. We identify a positive elite peer effect on enrolment in elite programmes and disentangle underlying mechanisms. Exploiting a lottery in the assessment system, a causal mediation analysis shows the overall positive peer effect reflects a positive effect on application behaviour (conditional on GPA), which dominates a negative effect on student GPA. We consider implications for income mobility finding that encouraging further mixing between elite and non-elite students in high school could improve mobility across the whole distribution. 

The health effects of universal early childhood interventions: evidence from Sure Start 

Revise  & resubmit at the Journal of Human Resources 

Joint  with Gabriella Conti, Christine Farquharson, Rita Ginja and Maud Pecher

Abstract: Early Childhood Interventions (ECI) offering disadvantaged children preschool and family support services in the US show long-lasting health impacts. Can these benefits hold when these programs are offered to all children in contexts with universal healthcare? We evaluate the short- and medium-term health impacts of Sure Start, a universal integrated ECI in England, exploiting its 11-year rollout and administrative hospitalizations data. One additional Sure Start center per thousand age-eligible children increases hospitalizations by 10% at age 1, but reduces them by 8-9% across ages 11-15. Impacts are concentrated in disadvantaged areas and likely driven by both health and non-health services.  

Parental labour market instability and children's mental health during the pandemic 

Joint with Christine Farquharson, Sonya Krutikova, Andrew McKendrick and Almudena Sevilla

Abstract: Childhood is a critical period for development of mental health: episodes of mental illness during this time often recur in adulthood but early intervention can be highly effective at reducing this persistence. Understanding determinants of child mental health is therefore key for the design of timely effective interventions. In this paper we study the impact of the COVID pandemic on the mental health of school-age children in England. We focus on how the significant pandemic induced disruptions to parental employment affected children and through what mechanisms, using unique nationally representative data we collected. We estimate an augmented Value Added model accounting for potential measurement error in child mental health scores. We find that changes in parental labour market circumstances over the course of the pandemic had a significant and negative impact on children’s mental health of around 9% of a standard deviation equivalent to around 30% of the total average decrease in mental health in our sample over the course of the pandemic. Granular data on labour market experiences over the pandemic shows that it was stability of parental labour market trajectories that was key for child well-being. Mechanisms for the adverse impact of disruptions are likely to include negative impacts on actual and expected household economic situation as well as on parental psychological well-being.

The impact of area level mental health interventions on outcomes for secondary school pupils: Evidence from the HeadStart programme in England

Joint with Tanya Lereya, Yeosun Yoon, Ruth Gilbert and Jessica Deighton, forthcoming at The Economics of Education Review

Abstract: In light of the dramatic rise in mental health disorders among adolescents seen in the past decade across the world, there is an urgent need for robust evidence on what works to combat this trend. This paper provides the first robust evaluation of the impacts on school outcomes of 6-year funding programme (HeadStart) for area-level mental health interventions for adolescents. Exploiting educational administrative data on ten cohorts of state-educated secondary school students, we use the synthetic control method to construct counterfactual outcomes for areas that received the funding. We show that the funding did not affect students’ absenteeism or academic attainment, but it prevented around 800 students (c. 10% of students typically excluded yearly) from being excluded in its first year. The transient nature of this effect suggests that sustained funding for intervention is a necessary but not sufficient condition to maintain programme effectiveness over time. 

The Short- and Long-term Effects of Student Absence: Evidence from Sweden

Joint with Daniel Kamhofer, Martin Karlsson and Therese Nilsson

The Economic Journal, 2022

Abstract: Despite the relatively uncontested importance of promoting school attendance in the policy arena, little evidence exists on the causal effect of school absence on long-run socio-economic outcomes. We address this question by combining historical and administrative records for cohorts of Swedish individuals born in the 1930s. We find that absence significantly reduces contemporaneous academic performance, final educational attainment and labor income throughout the life-cycle. The findings are consistent with a dynamic model of human capital formation, whereby absence causes small immediate learning losses which cumulate to larger human capital losses over time and lead to worse labor market performance. 

Does more free childcare help parents work more? 

Joint with Mike Brewer, Claire Crawford and Birgitta Rabe

Labour Economics, 2022  

Abstract: Many governments are considering expanding childcare subsidies to increase the labour force participation of parents (especially mothers) with young children. In this paper, we study the potential impact of such a policy by comparing the effects of offering free part-time childcare and of expanding this offer to the whole school day in the context of England. We use two different strategies exploiting free childcare eligibility rules based on date of birth. Both strategies suggest that free part-time childcare only marginally affects the labour force participation of mothers whose youngest child is eligible, but expanding from part-time to full-time free childcare leads to significant increases in labour force participation and employment of these mothers. These effects emerge immediately and grow over the months following entitlement. We find no evidence that parents adjust their labour supply in anticipation of their children's entitlement to free childcare.

Early Childhood Development, Human Capital and Poverty 

Joint with Orazio Attanasio and Costas Meghir 

Annual Review of Economics, 2022

Abstract: Children’s experiences during early childhood are critical for their cognitive and socioemotional development, two key dimensions of human capital. However, children from low-income backgrounds often grow up lacking stimulation and basic investments, which leads to developmental deficits that are difficult, if not impossible, to reverse later in life without intervention. The existence of these deficits is a key driver of inequality and contributes to the intergenerational transmission of poverty. In this article, we discuss the framework used in economics to model parental investments and early childhood development and use it as an organizing tool to review some of the empirical evidence on early childhood research. We then present results from various important early childhood interventions, with an emphasis on developing countries. Bringing these elements together, we draw conclusions on what we have learned and provide some directions for future research. 

Although there is a large gap between Black and White American life expectancies, the gap fell 48.9% between 1990-2018, mainly due to mortality declines among Black Americans. We examine age-specific mortality trends and racial gaps in life expectancy in rich and poor U.S. areas and with reference to six European countries.

Inequalities in life expectancy are starker in the U.S. than in Europe. In 1990 White Americans and Europeans in rich areas had similar overall life expectancy, while life expectancy for White Americans in poor areas was lower. But since then even rich White Americans have lost ground relative to Europeans. Meanwhile, the gap in life expectancy between Black Americans and Europeans decreased by 8.3%.

Black life expectancy increased more than White life expectancy in all U.S. areas, but improvements in poorer areas had the greatest impact on the racial life expectancy gap. The causes that contributed the most to Black mortality reductions included: Cancer, homicide, HIV, and causes originating in the fetal or infant period.

Life expectancy for both Black and White Americans plateaued or slightly declined after 2012, but this stalling was most evident among Black Americans even prior to the COVID-19 pandemic. If improvements had continued at the 1990-2012 rate, the racial gap in life expectancy would have closed by 2036. European life expectancy also stalled after 2014. Still, the comparison with Europe suggests that mortality rates of both Black and White Americans could fall much further across all ages and in both rich and poor areas. 

Mortality inequality in England over the past 20 years

Fiscal Studies, 2021

Abstract: In this paper, we study the evolution of age-group- and gender-specific mortality and mortality inequality in England between 2003 and 2016, by comparing small geographic areas ranked by deprivation and grouped into bins of similar population size. We show that across all age groups, but especially in the older age groups (65+), there has been a clear and significant reduction in rates of mortality since 2003. In spite of these improvements, we continue to see significant inequalities in mortality across most age groups in 2016 and evidence of rising inequalities among women in the 65+ and men in the 80+ age groups. Furthermore, we see a striking stalling of the downwards trend in mortality and mortality inequality observed between 2003 and 2010 during the years of economic austerity in the aftermath of the 2008 financial crisis in England between 2010 and 2016. Analysis of specific causes of death among adults aged 20–79 allows us to examine the drivers and dynamics of these trends in more depth, as well as to consider scope for, and types of, interventions that would be appropriate at different ages.

The gendered division of paid and domestic work under lockdown

Joint with Alison Andrew, Monica Costa Dias, Christine Farquharson, Lucy Kraftman, Sonya Krutikova, Angus Phimister, Almudena Sevilla

Fiscal Studies, 2022

Abstract: COVID-19 has uprooted many aspects of parents' daily routines, from their jobs to their childcare arrangements. In this paper, we provide a novel description of how parents in England living in two-parent opposite-gender families divided paid and unpaid work during the first national lockdown. We find that mothers' paid work took a larger hit than that of fathers on three key margins: participation, hours of paid work, and uninterrupted hours. These gender differences in paid work cannot be explained by the industries and occupations in which parents worked prior to lockdown. Instead, the differences grow once we account for these factors, which is consistent with gender differences in the lockdown’s impact on labour supply. We find that mothers spent substantially longer doing childcare and housework than their partners.  Gender differences in the allocation of domestic work cannot be straightforwardly explained by differences in employment or prior earnings. Substantial gender asymmetries emerge when one partner stopped working for pay during the crisis: mothers always did substantially more domestic work than fathers in their equivalent situation.

Inequalities in Children’s Experiences of Home Learning during the COVID-19 Lockdown in England

Joint with Alison Andrew, Monica Costa Dias, Christine Farquharson, Lucy Kraftman, Sonya Krutikova, Angus Phimister and Almudena Sevilla

Fiscal Studies, 2021

Abstract: This paper combines novel data on the time use, home learning practices and economic circumstances of families with children during the COVID-19 lockdown with pre-lockdown data from the UK Time Use Survey to characterise the time use of children and how it changed during lockdown, and to gauge the extent to which changes in time use and learning practices during this period are likely to reinforce the already large gaps in educational attainment between children from poorer and better-off families.We find considerable heterogeneity in children’s learning experiences-amount of time spent learning, activities undertaken during this time and availability of resources to support learning. Concerningly, but perhaps unsurprisingly,this heterogeneity is strongly associated with family income and in some instances more so than before lockdown. Furthermore,our analysis suggests that any impacts of inequalities in time spent learning between poorer and richer children are likely to be compounded by inequalities not only in learning resources available at home, but also those provided by schools.

Inequalities in response to school closures over the course of the first COVID-19 lockdown

Joint with Christine Farquharson, Sonya Krutikova, Angus Phimister, Adam Salisbury, Almudena Sevilla

IFS Working Paper, February 2021

Abstract: In England, school closures due to the COVID-19 pandemic represented a sudden but relatively longlasting shock to children’s education. During the first lockdown, schools were closed to all but the most vulnerable children and those with key worker parents from 23 March to the end of May; they began to reopen in June and July, but some children remained out of the classroom until September. In this paper, we follow a panel of children between April/May and June/July 2020 to document how home learning experiences changed over the course of the first lockdown, and how these changes were influenced by the partial and voluntary return to school over this period. 

We find little evidence that children adapted to home learning over the course of the lockdown; instead, learning time fell among those who were not offered the chance to return to school. Pupils who returned to school saw their learning time rise substantially, even conditional on observable and unobservable characteristics. However, while the opportunity to return to in-person schooling at least part-time was relatively evenly distributed, better-off parents were around 50% more likely to send their children back to school when given the choice. Since better-off students also increased their learning time by more when they returned to school, our results suggest that substantial targeted support will be needed to help disadvantaged pupils catch up, even after all children are back in the classroom.

How does the association between special education need and absence vary overtime and across special education need types?

Joint with Tanya Lereya, Yeosun Yoon, Ruth Gilbert and Jessica Deighton

 European Journal of Special Needs Education, 2022

Abstract: School absenteeism is a significant social and public health problem, and it has considerable negative consequences on the development of children and adolescents not only in the short term but also in the long term. We investigated special education needs (SEN) as a risk factor for absenteeism. For 418,455 mainstream secondary school students from 151 local authorities in England, multilevel linear regression models were run to investigate the association between SEN, SEN types and absenteeism during their secondary school period from year 7 to year 11. Local authority level variation was also investigated. Adolescents with SEN were more likely to be absent than their peers without SEN. Of adolescents with SEN, those with physical disability, followed by those with behavioural, emotional and social difficulties had the highest rates of absenteeism. Absenteeism rates increased as adolescents grew older. The association between absenteeism and having any SEN varied substantially across Local authorities. The results suggest that early interventions/preventative measures could mitigate loss of schooling due to absence. Moreover, the substantial variation in attendance for children across different local authorities suggest that there may be scope for local authorities to influence absence rates among adolescents.
