Economists increasingly accept that social norms have powerful effects on human behavior and outcomes. In recent history, one norm widely adhered to in most developed nations has been for men to be the primary breadwinner within mixed-gender households. As women have entered the labor market in...

How do institutions and peer groups shape skills? We exploit a universal free-choice reform signaling less importance of advanced math-science in high school. We show how it amplified the fall in math-science skills and triggered gender convergence as boys crowded-in the free-choice reform. We...

We study the economic structure of the life of Harry Potter and his co-actors as an economic model that governs the social organization of their economic activities. Our goal is to study and understand the internal consistency of the Potterian economic model and explore the relationships between...

We set up a theoretical framework to analyze the possible role of economic growth and technological progress in the erosion of social capital. Under certain parameters, the relationship between technological progress and social capital can take the shape of an inverted U curve. We show the...

Why are men more risk tolerant than women, and why do they invest more than women? I test whether identity stereotypes help explain this heterogeneity. I manipulate identity in a controlled environment by priming its salience to subjects. Men whose identity is primed take on more risk, and...

Relationships have changed dramatically in the last fifty years. Fewer couples are marrying, more are cohabiting. Reasons for this shift abound, but the shift may have consequences of its own. A number of models predict that those cohabiting will specialize less than those marrying. Panel data...

Few economic indicators have more salience and pervasive financial impact on everyday lives in the United States than poverty measures. Nevertheless, policymakers, researchers, advocates, and legislators generally do not understand the details of poverty measure mechanics. These detailed...

We examine how the speed of learning and best-response processes depends on homophily: the tendency of agents to associate disproportionately with those having similar traits. When agents' beliefs or behaviors are developed by averaging what they see among their neighbors, then convergence to a...
