PhD Thesis Summary

My dissertation contains three papers on household time allocation and human capital, investigating how the decisions of mothers, fathers, and children shape inequality of human capital. By combining rich micro data with quantitative macro models and causal inference, I provide new evidence on how inequality arises from household choices, and identify mechanisms through which policy can reduce these disparities.

Chapter 1: Mothers (Job Market Paper)
My job market paper speaks to the puzzle of why Black women in the U.S. exhibit higher labour-market attachment than White women with similar observables. High-wage Black women return to work sooner after childbirth, incurring a smaller "child penalty". Using a structural life-cycle model on PSID data, I show this is driven by heightened risks in labour and marriage markets.

Chapter 2: Fathers
This paper shows that heterogeneity in fathers' parenting time is a critical but overlooked driver of inequality in children's human capital. Using a dynamic factor model with instrumental variables, I find that equalising fathers' time across childhood stages would reduce disparities by 22% in cognition and 49% in health outcomes.

Chapter 3: Children
This paper shows that road infrastructure critically shapes how rainfall shocks affect education in Ethiopia. While existing research emphasises child labour, I highlight commuting as an additional mechanism. Using panel data from 2002–2016, I document that excessive rainfall increases commuting time and reduces enrollment, but only in villages with dirt roads.

Structural Labor Gender

This paper documents novel findings that Black women in the U.S. experience child penalties in a way that fundamentally differs from those faced by White women. The child penalty in employment is half as large for Black women (10%) compared to White women (30%). Educated, high-wage, married Black women return to the labor market almost immediately after childbirth. This racial difference in the labor-leisure tradeoff is driven by subjective expectations: Black households face a higher probability of layoff in the labor market, as well as higher probabilities of separation, divorce, and not getting remarried. Using a structural life-cycle model, I show that high-ability Black women use labor market attachment for self-insurance, while sacrificing their own leisure to maintain high levels of parenting time. This generates lower observed penalties in wages and labor force participation, but larger unobserved penalties via sacrificed leisure. Counterfactual simulations reveal that equalizing marriage probabilities and layoff shocks can close up to 75% of the racial gap in child penalties in employment. Welfare improves primarily through increased leisure for Black women. These results highlight the importance of uncertainty and dynamic household choices in explaining persistent racial gaps in female labor supply and child penalties.

This study explores the impact of parental time investment on children's human capital development, with a particular emphasis on distinguishing between maternal and paternal contributions. Using household data from the PSID time diary and Child Development Supplement, our empirical analysis reveals significant heterogeneity and endogeneity in paternal time investment. To quantify these effects, we employ a dynamic factor model framework to estimate the production function for children's human capital, focusing on cognitive and health outcomes. To address the endogeneity of parental time investment, we implement a control function approach that leverages local labor demand shocks as instruments. Our counterfactual analysis demonstrates that equalizing paternal time investment across different stages of child development can significantly reduce inequalities in cognitive and health outcomes by adolescence. Specifically, equalizing paternal time during both early and middle childhood leads to a 22 percent reduction in cognitive disparities and a 49 percent reduction in health disparities. These findings underscore the pivotal role of paternal time investment in shaping inequalities in children's human capital development.

Previous findings often find that rainfall leads to lower education outcomes in developing countries, emphasizing labor market channels: when rainfall raises agricultural wages, the opportunity cost of schooling rises and children substitute into work. This paper shows that commuting to school represents another important mechanism. Using longitudinal data from Ethiopia spanning 2002–2016, which track children's time allocation, cognition tests, and village-level precipitation, I find that moderate drought conditions significantly increase math cognition by 1.28 standard deviations, increase enrollment by 0.37 percentage points, and increase after school study time by 0.38 hours per day, while reducing travel time to school by 0.35 hours. Effects diminish at more extreme drought levels but remain positive, with larger impacts in rural areas. These results suggest that in settings with fragile school access, commuting costs play an important role in shaping the education impact of climate shocks, highlighting transportation infrastructure as a critical margin of resilience.

We provide the first causal evidence that structural transformation, or service sector expansion, has led to a decline in women's intrahousehold bargaining power in 15 Sub-Saharan African countries. Using two-way fixed effects and instrumental variable estimations, we show that this decline is particularly pronounced in countries with more restrictive gender norms. To ensure robustness, we further validate our findings by leveraging sub-national statistics and within-country variations. To reconcile this fact, we add a new feature --- social stigma against females working in the service sector --- into an otherwise standard structural transformation model. We show that structural transformation can reduce the female-to-male wage ratio and prevent female empowerment if the social stigma exceeds a threshold.

What is the macroeconomic impact of flooding? With the increasing frequency and severity of flooding events, climate change is expected to impact macroeconomic and financial stability. Combining global data on satellite images of flooding, precipitation, trade, and comprehensive panel data on economic performance, I use Jorda's local projection method with maximum precipitation serving as an external instrument for causal identification. Flood significantly increases the inflation rate by about 3 percentage points (p.p.), and raises import (share of GDP) and export by about 5 p.p., and 2 p.p. respectively, predominantly affecting developing countries. Flooding shock has significant spillover effects on inflation through trade. An additional day of flooding among all trading partners raises domestic inflation by about 5 p.p.
