In belligerent countries, male-to-female sex ratios at birth increased during and shortly after the two world wars. These rises occurred amidst dramatically changed marriage-market conditions caused by war-related declines in adult sex ratios, and still defy explanation. Based on county-level...

In belligerent countries, male-to-female sex ratios at birth increased during and shortly after the two world wars. These rises still defy explanation. Several causes have been suggested (but not tested) in the literature. Many of these causes are proximate in nature, reflecting behavioral...

Women can bear own children or adopt them. Extending economic theories of fertility, we provide a first theoretical treatment of the demand for adoption. We show that the propensity to adopt a child increases in the degree of own altruism, infertility, relatedness to the child, costs of own...

Based on county-level census data for the German state of Bavaria in 1939 and 1946, we use World War II as a natural experiment to study the effects of sex ratio changes on out-of-wedlock fertility. Our findings show that war-induced shortfalls of men to women significantly increased the...

We develop a theoretical model of mating behavior and parental investment in children under asymmetry in kin recognition between men and women that provides a microfoundation for the institution of marriage. In the model, men and women derive utility from consumption and reproductive success,...
