We question the received wisdom that birth limitation was absent among historical populations before the fertility transition of the late nineteenth-century. Using duration and panel models on family-level data, we find a causal, negative short-run effect of living standards on birth spacing in...

In this paper, we use 2008-2013 American Community Survey data to update and further probe evidence on son preference in the United States. In light of the substantial increase in immigration, we examine this question separately for natives and immigrants. Dahl and Moretti (2008) found earlier...

This paper examines evidence on the role of assimilation versus source country culture in influencing immigrant women’s behavior in the United States - looking both over time with immigrants' residence in the United States and across immigrant generations. It focuses particularly on labor...

We study the causal effect of maternal education on childhood immunization rates. We use the Compulsory Education Law (CEL) of 1997, and the differentiation in its implementation across regions, as instruments for schooling of young mothers in Turkey. The CEL increased the compulsory years of...

We study the effect of educational attainment on family formation using regression discontinuity designs generated by centralized admissions processes to both secondary and tertiary education in Finland. Admission to further education at either margin does not increase the likelihood that men...

Fertility has a strong biological component generally ignored by economists. Using the UK Biobank, we analyze the extent to which genes, proxied by polygenic scores, and the environment, proxied by early exposure to the contraceptive pill diffusion, affect age at first sexual intercourse, age at...

This paper presents novel causal evidence on the effects of pro-natalist cash transfers on fertility, sex ratio at birth, and infant health. In the context of South Korea, I exploit rich spatial and temporal variation in cash transfers provided to families with newborn babies and the universe of...

This chapter reviews the literature on the causal effects of policies on fertility. It focuses on evidence from experiments and quasi-experiments in low fertility contexts, including studies from Europe, Northern America, Oceania and Asia. Making no a priori restrictions on policy type, the...

We study the impacts of childbirth on maternal mental health, the role of pro-natalist cash transfers, and the fertility consequences of maternal mental health. Using claims-level data from South Korea's universal healthcare system, we find that mental health diagnoses rise by 34.8% (198.7%)...

Robots have radically changed the demand for skills and the role of workers in production. This phenomenon has replaced routine and mostly physical work of blue collar workers, but it has also created positive employment spillovers in other occupations and sectors that require more social...
