Identifying climate shocks in Young Lives communities: estimating weather conditions using a global gridded time series

This technical note describes the process of selecting, preparing and matching external climate data to Young Lives respondents’ locations to derive ex-post estimates of climate conditions at a community level in regions which traditionally have poor climate data collection capacity. The note also details how to use these matched data, specifically precipitation records, to assess experiences of anomalous conditions relative to historical mean conditions for each community. Finally, it briefly details the structure and content of the publicly archived dataset, and how this dataset may be used for further research

Psychosocial Competencies and Risky Behaviours in Peru

The authors use a unique longitudinal dataset from Peru to investigate the relationship between psychosocial competencies related to the concepts of self-esteem, self-efficacy and aspirations, and a number of risky behaviours at a crucial period of transition between adolescence and early adulthood. First, the researchers document a high prevalence of risky behaviours, with one in two individuals engaging in at least one risky activity by the age of 19, and a dramatic increase between the ages of 15 and 19. Second, the document finds a pronounced pro-male bias and some differences according to area of residence, particularly in the consumption of alcohol, which is more prevalent in urban areas. Third, the report finds a negative correlation (robust to a number of specifications) between early self-esteem and later risky behaviours. Further, aspiring to higher education at the age of 15 is found to be correlated with a lower probability of drinking and of engaging in criminal behaviours at the age of 19. Similarly, such aspirations protect girls from risky sexual behaviours

What if it never happened? Subjective treatment effects of a negative shock on youth labour market outcomes in developing countries

This paper examines the subjective treatment effects of a negative shock created by the COVID-19 pandemic on the labour market outcomes of young adults in India, Peru, and Vietnam. We leverage subjective counterfactual outcomes at the individual-level that were purposely collected from over 7,000 individuals to this aim. Our findings suggest that the shock denied employment opportunities and reduced earnings. On average, the pandemic reduced monthly earnings by 19.4% and employment levels by 17.5% in our three-country-sample. Country-specific magnitudes are lowest for India and highest for Vietnam. However, these average effects belie that a substantial proportion of individuals, particularly those from disadvantaged backgrounds, are pushed into employment by the pandemic. This frequently comes at the expense of their education, hinting at youth labour acting as a buffer against transitory shocks. According to our findings, the perceived effects of the pandemic on labour market outcomes carry important implications for young people's well-being and behaviour. Individuals who are denied employment display significantly higher rates of anxiety, lower rates of COVID-19 vaccination, and lower desired fertility

Social Protection and Foundational Cognitive Skills During Adolescence: Evidence From a Large Public Works Program

Many low- and middle-income countries have introduced public works programs (PWPs) to fight poverty. This paper provides the first evidence that children from families who benefit from PWPs show increased foundational cognitive skills. The results, based on unique tablet-based data collected as part of a long-standing longitudinal survey, show positive associations between participation in the Productive Safety Net Programme (PSNP) in Ethiopia during childhood with long-term memory and implicit learning, and suggestive evidence for working memory. These associations appear to be strongest for children whose households were still PSNP participants in the year of data collection. Evidence suggests that the association with implicit learning may be operating partially through children\u27s time reallocation away from unpaid labor responsibilities, while the association with long-term memory may in part be due to the program\u27s success in remediating nutritional deficits caused by early-life rainfall shocks

Human Capital Development:New Evidence on the Production of Socio-emotional Skills

We estimate a dynamic model of multidimensional human capital development from childhood through adolescence and into early adulthood for a Peruvian cohort born in 1994. We exploit multiple measures of cognitive and socio-emotional skills and a latent factor structure to estimate flexible skills production functions between the ages of 8 and 22. We focus particularly on socio-emotional skill development, and provide the first estimates of such skill production over such a long period in a developing country context. In the last period, when individuals reach adulthood at age 22, we show that socio-emotional skills can be separated into two distinct domains - social skills and task effectiveness skills- which develop differently especially with regard to time use and cross-productivity with cognition. We find that individuals with higher task effectiveness are less likely to have engaged in risky behaviours such as smoking, taking drugs, and engaging with gangs

Social Protection and Foundational Cognitive Skills During Adolescence: Evidence from a Large Public Works Programme

Many low- and middle-income countries have introduced Public Works Programmes (PWPs) to fight poverty. PWPs provide temporary cash-for-work opportunities to boost poor households’ incomes and to provide better infrastructure to local communities. While PWPs do not target children directly, the increased demand for adult labour may affect children’s development through increasing households’ incomes and changing household members’ time uses. This paper expands on a multidimensional literature showing the relationship between early life circumstances and learning outcomes and provides the first evidence that children from families who benefit from PWPs show increased foundational cognitive skills (FCS). We focus on four child FCS: inhibitory control, working memory, long-term memory, and implicit learning. Our results, based on unique tablet-based data collected as part of a 20-year longitudinal survey, show positive associations of family participation in the Productive Safety Net Programme (PSNP) in Ethiopia during childhood on long-term memory and implicit learning, with weaker evidence for working memory. These associations appear to be strongest for children whose households were still PSNP participants in the year of data collection. We find suggestive evidence that, the association with implicit learning may be operating through children’s time reallocation away from unpaid labour responsibilities, while the association with long-term memory may be due to the programme’s success in remediating nutritional deficits caused by early life rainfall shocks. Our results suggest that policy interventions such as PWPs may be able to mitigate the effects of early poverty on cognitive skills formation and thereby improve children’s potential future outcomes

How Early Nutrition and Foundational Cognitive Skills Interconnect? Evidence from Two Developing Countries

We use unique data collected in Ethiopia and Peru as part of the Young Lives Study to investigate the relationship between early undernutrition and four foundational cognitive skills, the first two of which measure executive functioning: working memory, inhibitory control, long-term memory, and implicit learning. We exploit the rich longitudinal data available to control for potential confounders at the household level and for time-invariant community characteristics. We also exploit the availability of data for paired-siblings to obtain household fixed-effects estimates. Overall, we find robust evidence that stunting is negatively related with the development of executive functions, predicting reductions in working memory and inhibitory control by 12.6% and 5.8% of a standard deviation. Our results shed light on the mechanisms that explain the relationship between early nutrition and school achievement tests suggesting that good nutrition is an important determinant of children’s learning capacities

“United We Stand Divided We Fall” : Maternal Social Participation and Children’s Nutritional Status in Peru

In previous literature, social capital has been hypothesized as a substitute for other forms of capital, such as physical and human capital. This paper contributes to this literature, studying the association between mothers’ access to social capital via participation in community organizations and their children’s nutritional status at 1 and 5 years. Using the Peruvian sample of the Young Lives project, this study suggests that, where human capital is scarce, social capital might have important implications for child development. Maternal social capital is positively associated with height at 1 year old for those children whose mothers have no formal education. No significant association is found at 5 years of age

Long-term effects of rainfall shocks on foundational cognitive skills: evidence from Peru

Global warming is changing precipitation patterns, harming communities strongly tied to agricultural production, particularly in low-and-middle income countries (LMICs). Whilst the long-term effects of being exposed to rainfall shocks early in life on school achievement tests are well-established, there is little population-based evidence from LMICs on the mechanisms through which these shocks operate. This paper analyses the effects of early exposure to rainfall shocks on four foundational cognitive skills (FCSs), including executive functions (EF) that have been found to be key predictors of educational success. These skills were measured via a series of tablet-based tasks administered in Peru as part of the Young Lives longitudinal study (YLS). We combine the YLS data with gridded data on monthly precipitation to generate monthly, community-level rainfall estimates. The key identification strategy relies on temporary climatic shocks being uncorrelated with other latent determinants of FCS development. Our results show significant negative effects of early life exposure to rainfall shocks on EF. We also find evidence of rainfall shocks decreasing households' abilities to invest in human capital, which may affect both FCS and domain-specific test scores. Interestingly, social policies providing affected households with additional resources partially offset the effects of the rainfall shocks

Late-Childhood Foundational Cognitive Skills Predict Educational Outcomes Through Adolescence and Into Young Adulthood: Evidence from Ethiopia and Peru

We estimate the associations between a set of foundational cognitive skills (inhibitory control, working memory, long-term memory, and implicit learning) measured at age 12 and educational outcomes measured at ages 15 and 19-20 in Ethiopia and Peru (the Young Lives study). The estimates adjust for a rich set of lagged controls and include measurements of children’s general abilities. For a subset of the outcomes, we exploit within-household variation. Working memory and long-term memory are consistently and positively associated with subsequent domain-specific cognitive achievement tests in both countries, university enrolment in Peru (working memory) and lower secondary-school completion in Ethiopia (long-term memory). Inhibitory control predicts subsequent math-test scores in both countries, and grade attainment in Ethiopia. These results provide additional evidence to justify the importance of promoting investments in cognitive skills throughout childhood and adolescence, and these results potentially elucidate how investments in children impact their educational achievements
