This paper investigates the causal impact of free primary education (FPE) on fertility decisions among parents in sub-Saharan Africa, focusing on the interplay between the policy, intra-household bargaining, and cultural norms. Using Demographic and Health Survey data and exploiting the...

This paper characterizes optimal education and population policies within a continuous-time overlapping generations (OLG) framework where fertility, schooling duration, and health expenditures are endogenous. In this model, mortality risk is driven by a negative congestion effect from population...

I develop and estimate a life-cycle discrete-choice model of fertility and female labor supply to study the optimal design of a range of child-related policies. First, I examine two German reforms that introduced wage-contingent parental leave payments and expanded access to low-cost public...

Official Spanish birth registry data report sex ratios well above expected levels between 1975 and 2000, peaking at 109 boys per 100 girls in the early 1980s, the highest in the world at that time. Prior research has attributed these elevated ratios to factors such as maternal age, birth order,...

We establish a positive relationship between work from home (WFH) and fertility, drawing on our Global Survey of Working Arrangements (38 economies, N = 19,241) and our US Survey of Working Arrangements and Attitudes (N = 102,411). Respondents who WFH at least 1 day per week had more biological...

We study political shocks as potential birth outcomes stressors, specifically the unexpected result of the 2016 U.S. presidential election. We investigate this two-sided shock using an innovative data linkage: Colorado voter registrations and birth certificates, matched by sex, birth year, and...

What ignited humanity's momentous ascent from millennia of stagnation to an era of sustained economic growth? And what are the roots of the vast disparities in the wealth of nations? These enduring mysteries, which have preoccupied scholars across generations, lie at the core of Unified Growth...

How do institutional barriers to migration shape fertility in developing economies? We analyze the staggered removal of institutional barriers to rural-to-urban migration across 283 Chinese cities. We find that reducing these frictions led to a significant and persistent increase in fertility in...

We document that women strategically sort into "family-friendly" sectors characterized by lower returns to experience but lower per-child penalties before the birth of their first child. This anticipatory sorting represents an ex-ante cost of motherhood that is entirely missed by conventional...

We investigate how fertility relates to work from home (WFH) in the post-pandemic era, drawing on original data from our Global Survey of Working Arrangements and U.S. Survey of Working Arrangements and Attitudes. Realized fertility from 2023 to 2025 and future planned fertility are higher among...

We study the labor market impact of unplanned pregnancy among women using long-acting reversible contraceptives to delay pregnancy. While most women successfully delay, some have unplanned pregnancies, providing quasi-random variation in pregnancy timing. Analyzing linked health and labor market...

In this study, we use data from the recent round of the Multiple Indicator Cluster Surveys (MICS) to estimate the effect of son preference on reproductive behaviour in Uzbekistan. We find strong evidence of differential stopping and spacing behaviour among Uzbek women. Women are significantly...

Global fertility is declining, yet it remains unclear whether and how climate-related hazards contribute to realized fertility change. This paper combines global fertility data with disaster records for 1950–2023 to estimate fertility responses to climate-related hazards, distinguishing...

This study analyzes monthly price data for urea, phosphate rock, diammonium phosphate (DAP), triple superphosphate (TSP), and potassium chloride from the World Bank, covering the period from January 1967 to September 2024. The objective is to investigate interdependencies among major fertilizer...
