The paper explains long-term changes in birth, death rates, and in attitude to personal consumption by evolution of preferences by means of cultural transmission. When communities are culturally isolated, they are focused on population growth, which results in large fertility and welfare transfers to children, limited adult consumption, and lack of old-age support. With increasing cultural contact across communities, successful cultural traits induce their hosts to increase their social visibility by limiting fertility and increasing longevity via higher individual consumption. Empirical analysis confirms that social visibility, as measured by the number of language versions of Wikipedia biographical pages, is associated with fewer children and longer lifespan. The presence of notable individuals precedes reduced aggregate birth rates.

We investigate the impact of male–female conflict over gender norms on marital outcomes. As marriage requires mutual agreement regarding the role of husband and wife, we hypothesize that a person who is less likely to encounter a potential mate with similar gender norms will face a lower chance of marrying. Even if two parties marry despite a difference in gender norms, their marriage may be more vulnerable to external shocks, making divorce more likely relative to their counterparts without gender norm conflict. Finally, we predict that in the presence of gender norm conflict, high-skilled individuals may be less likely to get or stay married relative to low-skilled individuals, as the former group faces better outside options. Estimates from an analysis of U.S. marriage markets differentiated by birth cohort, state, race, and skill level support our theoretical predictions. Additional extensions explore heterogeneous effects and additional outcomes such as the presence of children in the household.

This paper explores the extent to which child labor perpetuates the cycle of household poverty, as well as food insecurity using the sixth round of the Ghana Living Standards Survey. The study employs a counterfactual framework and an endogenous treatment effect econometric technique to accurately examine the causal link between child labor and long-term household poverty and food security. Results suggest a positive relationship between early paid work and long-term poverty and food insecurity. This finding provides empirical evidence to indicate that child labor has the potential to create and perpetuate poverty traps. From a policy perspective, findings from this study also contribute to the modern policy debates surrounding the achievement of the sustainable development goals on reducing poverty and hunger in developing countries.
