Male children have a survival disadvantage in most societies, a situation largely attributed to genetic fatality. Little is known about whether male genetic expression can be constrained by appropriate social interventions. We examine whether, and how, change in political regime type affects...

What pay can a worker expect when he is unsure about his ability (or effort supply) and that of his co-workers? Workers have varying (unobserved) abilities, but can observe their distributions in the population. We uncover four findings. First, we uniquely characterize workers' expected pay in a...

Abstract:Popularity bias -- the bandwagon effect -- is the tendency to select the most popular from alternative(s). We incorporate this into a parsimonious dynamic model of an anonymous bipartite economy with heterogeneous agents and show that anti-egalitarian networks (where the smallest...

Do the effects of government policy response to health crises differ for for-profit and not-for-profit organizations? We address this question through the lens of a two-sector continuous-time individual-based mean-field theoretical model that incorporates a non-random social network. Using...

We study the dynamic stability of fidelity networks, which are networks that form in a mating economy of agents of two types (say men and women), where each agent desires direct links with opposite type agents, while engaging in multiple partnerships is considered an act of infidelity....

We propose a simple model of a mating economy in both monogamous and polygynous cultures, and derive implications for how polygyny affects individual and aggregate fertility. We find that an attractive woman is more likely to find a high-status husband. However, when polygyny is allowed,...

We analyze the implications of communitarianism-the tendency of people to organize into separate culturally homogeneous groups-for individual and group inequality in human capital accumulation. We propose a non-cooperative social interactions model where each individual decides how much time to...

We propose a simple model of a mating economy in both monogamous and polygynous cultures, and derive implications for how polygyny affects individual and aggregate fertility. We find that an attractive woman is more likely to find a high-status husband. However, when polygyny is allowed,...
