Early childhood development is becoming the focus of policy worldwide. However, the evidence on the effectiveness of scalable models is scant, particularly when it comes to infants in developing countries. In this paper, we describe and evaluate with a cluster-Randomized Controlled Trial an intervention designed to improve the quality of child stimulation within the context of an existing parenting program in Colombia, known as FAMI. The intervention improved children’s development by 0.16 of a standard deviation (SD) and children’s nutritional status, as reflected in a reduction of 5.8 percentage points of children whose height-for-age is below -1 SD.

This article examines the role that implementation science can play in evidence-based parenting programs. Although parenting programs can support parents in their caregiving roles, adapting and taking an evidence-based approach from one place to another without attending to implementation factors may contribute to poor impact in a new setting. Implementation science enables researchers to move beyond monitoring and evaluation of outcomes of a parenting program to understanding the process of putting the program into practice. Factors such as whether the program meets the needs of families and communities, how to secure buy-in from key stakeholders, what training and supervision are needed for the workforce, and ways that parenting programs can be integrated in existing infrastructure are all critical to successful implementation. Quality improvement can be built into the implementation process through feedback loops that inform rapid changes and testing cycles over time as a program is implemented. If researchers lead initial implementation of parenting programs, they must determine how the program can continue to work when using community workers and local systems rather than researchers. Open access components are especially important for the implementation of parenting programs in low- and middle-income countries to avoid prohibitive costs of proprietary programs and to benefit from flexibility in adapting components to meet the needs of particular local populations. Parenting programs benefit when policy makers, program leaders, and researchers attend not only to the what but also to the how of implementation.

We deliver one month's average profit to a randomly selected group of female microenterprise owners in Dandora, Kenya, arriving just in advance of an exponential growth in COVID-19 cases. Relative to a control group, firms recoup about one third of their initial decline in profit, and food expenditures increase. Control profit responds to economic conditions and government announcements during our study period, and treatment effects are largest when control profit is at its lowest. PPE spending and precautionary management practices increase to mitigate the health risks of more intensive firm operation, but only among those who perceive COVID-19 as a major risk.

We start by considering the implications of unequal parenting for children’s outcomes later in life. The literature on child development has established that the development process is cumulative and that early achievements foster additional learning later on. To highlight this issue, we document how parenting decisions and the family environment correlate with long-run outcomes such as graduating from college. In our analysis, we touch upon a dimension that is less salient in the two chapters: parenting style. We show that parenting style is not a mere by-product of families’ socio-economic status. Rather, it is associated with children’s outcomes in a way that is distinct from the influence of socio-economic factors such as parents’ education and race. We also argue that the choice of parenting styles is responsive to changes in the environment where children grow up. We show that parenting styles vary systematically across countries with different policies and institutions. This evidence suggests that understanding how parents adjust their behaviour to policy changes is important for drawing useful policy implications. These insights could be especially important for policies aiming to alleviate inequality in early childhood outcomes as parents’ endogenous responses could potentially either magnify or dampen the direct effect of policy interventions.

We use data from marriage records in Murcia, Spain, in the eighteenth century to study the role of women in social mobility in the pre-modern era. Our measure of social standing is identification as a don or doña, an honorific denoting high, though not necessarily noble, status. We show that this measure, which is acquired over the lifecycle, shows gendered transmission patterns. In particular, same-sex transmission is stronger than opposite-sex, for both sons and daughters. The relative transmission from fathers versus mothers varies over the lifecycle, and grandparents may affect the status of their grandchildren.

We develop a framework for quantifying barriers to labor force participation (LFP) and entrepreneurship faced by women in developing countries, and apply it to the Indian economy. We find that women face substantial barriers to LFP. The costs for expanding businesses through the hiring of workers are also substantially higher for women entrepreneurs. However, there is one area in which female entrepreneurs have an advantage: the hiring of female workers. We show that this is not driven by the sectoral composition of female employment. Consistent with this pattern, we find even without promoting female LFP, policies that boost female entrepreneurship can significantly increase female LFP. Counterfactual simulations indicate that removing all excess barriers faced by women entrepreneurs would substantially increase the fraction of female-owned firms, female LFP, earnings, and generate substantial gains in aggregate productivity and welfare. These gains are due to higher LFP, higher real wages and profits, and reallocation: low productivity male-owned firms previously sheltered from female competition are replaced by higher productivity female-owned firms previously excluded from the economy.

Can increasing control over earnings incentivize a woman to work, and thereby influence norms around gender roles? We randomly varied whether rural Indian women received bank accounts, training in account use, and direct deposit of public sector wages into their own (versus husbands') accounts. Relative to the accounts only group, women who also received direct deposit and training worked more in public and private sector jobs. The private sector result suggests gender norms initially constrained female employment. Three years later, direct deposit and training broadly liberalized women's own work-related norms, and shifted perceptions of community norms.

We investigate the role of training in reducing the gender wage gap using the British Household Panel Survey. On the basis of a life-cycle model and using tax and welfare benefit reforms as a source of exogenous variation, we evaluate the role of formal training and experience in defining the evolution of wages and employment careers, conditional on education. Training is potentially important in compensating for the effects of children, especially for women who left education after completing high school, but does not fundamentally change the wage gap resulting from labor market interruptions following child birth.

Poor early childhood development in low- and middle-income countries is a major public health problem. Efficacy trials have shown the potential of early childhood development interventions but scaling up is costly and challenging. Guidance on effective interventions’ delivery is needed. In an open-label cluster-randomized control trial, we compared the effectiveness of weekly home visits and weekly mother-child group sessions. Both included nutritional education, whose effectiveness was tested separately.

This paper offers for the first time a global picture of gender discrimination by the law as it affects women's economic opportunity and charts the evolution of legal inequalities over five decades. Using the World Bank's newly constructed Women, Business and the Law database, we document large and persistent gender inequalities, especially with regard to pay and treatment of parenthood. We find positive correlations between more equal laws pertaining to women in the workforce and more equal labor market outcomes, such as higher female labor force participation and a smaller wage gap between men and women.

We examine changes in inequality in socio-emotional skills very early in life in two British cohorts born 30 years apart. We construct comparable scales using two validated instruments for the measurement of child behaviour and identify two dimensions of socio-emotional skills: ‘internalising’ and ‘externalising’. Using recent methodological advances in factor analysis, we establish comparability in the inequality of these early skills across cohorts, but not in their average level. We document for the first time that inequality in socio-emotional skills has increased across cohorts, especially for boys and at the bottom of the distribution. We also formally decompose the sources of the increase in inequality and find that compositional changes explain half of the rise in inequality in externalising skills. On the other hand, the increase in inequality in internalising skills seems entirely driven by changes in returns to background characteristics. Lastly, we document that socio-emotional skills measured at an earlier age than in most of the existing literature are significant predictors of health and health behaviours. Our results show the importance of formally testing comparability of measurements to study skills differences across groups, and in general point to the role of inequalities in the early years for the accumulation of health and human capital across the life course.

We estimate production functions for cognition and health for children aged 1–12 in India, based on the Young Lives Survey. India has over 70 million children aged 0–5 who are at risk of developmental deficits. The inputs into the production functions include parental background, prior child cognition and health, and child investments, which are taken as endogenous. Estimation is based on a nonlinear factor model, based on multiple measurements for both inputs and child outcomes. Our results show an important effect of early health on child cognitive development, which then becomes persistent. Parental investments affect cognitive development at all ages, but more so for younger children. Investments also have an impact on health at early ages only.

Improving school quality with limited resources is a key issue of policy. This article uses a randomised controlled trial (RCT) to estimate the effectiveness of guided instruction methods as implemented in under-performing schools in Chile. The intervention improved performance substantially, and equally for boys and girls. However, the effect is mainly accounted for by children from relatively higher-income backgrounds. Basing our study on the Classroom Assessment Scoring System (CLASS) instrument, we document that the quality of teacher–student interactions is positively correlated with the performance of low-income students; however, the intervention did not affect these interactions. Guided instruction improves outcomes, but the challenge to reach the most deprived children remains.

This article studies the differential effect of targeting cash transfers to men or women on household expenditure on non-durables. We study a policy intervention in the Republic of North Macedonia that offers cash transfers to poor households, conditional on having their children attending secondary school. The recipient is randomised across municipalities, with payments targeted to either the mother or the father of the child. Targeting transfers to women increases the expenditure share on food by 4 to 5 percentage points. At low levels of food expenditure, there is a shift towards a more nutritious diet.
