Twin births are often construed as a natural experiment in the social and natural sciences on the premise that the occurrence of twins is quasi-random. We present new population-level evidence that challenges this premise. Using individual data for 17 million births in 72 countries, we...

The present paper provides new evidence that hospital delivery can significantly lower child mortality risks, especially among vulnerable young adolescent mothers in Bangladesh. We exploit the exogenous variation in community's access to local health facilities (both traditional and modern)...

This paper explores the mechanisms through which maternal employment affects the quality of household nutrition and the implications for obesity of family members. Using comparable samples from the American Time Use Survey (ATUS) and the Continuing Survey of Food Intake by Individuals (CSFII), I...

This paper explores how the relative circumstances of men and women following marital dissolution affect sex-selection behavior within marriages. China's 2001 divorce reform liberalized divorce in favor of women and secured women's property rights after separation. We use this improvement in...

This paper considers the question posed by popular media, do women like doing child care more than men? Using experienced emotions data paired with 24 hour time diaries from the 2010 American Time Use Survey, the paper explores gender differences in how men and women who have done some child...

This is one of only a few studies on the division of care leave for sick children between parents in Sweden and the first to attempt to examine the importance of differences in parents' work characteristics. The study uses register data for parents with children born in 1999-2002 to analyse two...

In this paper I compare the effect of entering parenthood on the spousal income gaps in lesbian and heterosexual couples using Swedish population wide register data. Comparing couples with similar pre-childbirth income gaps, a difference-in-differences strategy is used to estimate the impact of...

Previous research on maternal employment has disproportionately focused on married, college-educated mothers and examined either current employment status or postpartum return to employment. Following the life course perspective, we instead conceptualize maternal careers as long-term life course...
