January 2014Marry Your Like: Assortative Mating and Income Inequality
with Jeremy Greenwood, Nezih Guner, Georgi Kocharkov: w19829
Has there been an increase in positive assortative mating? Does assortative mating contribute to household income inequality? Data from the United States Census Bureau suggests there has been a rise in assortative mating. Additionally, assortative mating affects household income inequality. In particular, if matching in 2005 between husbands and wives had been random, instead of the pattern observed in the data, then the Gini coefficient would have fallen from the observed 0.43 to 0.34, so that income inequality would be smaller. Thus, assortative mating is important for income inequality. The high level of married female labor-force participation in 2005 is important for this result.

April 2013An Equilibrium Model of the African HIV/AIDS Epidemic
with Jeremy Greenwood, Philipp Kircher, Michèle Tertilt: w18953
Eleven percent of the Malawian population is HIV infected. Eighteen percent of sexual encounters are casual. A condom is used one quarter of the time. A choice-theoretic general equilibrium search model is constructed to analyze the Malawian epidemic. In the developed framework, people select between different sexual practices while knowing the inherent risk. The analysis suggests that the efficacy of public policy depends upon the induced behavioral changes and general equilibrium effects that are typically absent in epidemiological studies and small-scale field experiments. For some interventions (some forms of promoting condoms or marriage), the quantitative exercise suggests that these effects may increase HIV prevalence, while for others (such as male circumcision or increased incomes...
January 2012Technology and the Changing Family: A Unified Model of Marriage, Divorce, Educational Attainment and Married Female Labor-Force Participation
with Jeremy Greenwood, Nezih Guner, Georgi Kocharkov: w17735
Marriage has declined since 1960, with the drop being bigger for non-college educated individuals versus college educated ones. Divorce has increased, more so for the non-college educated vis-à-vis the college educated. Additionally, assortative mating has risen; i.e., people are more likely to marry someone of the same educational level today than in the past. A unified model of marriage, divorce, educational attainment and married female labor-force participation is developed and estimated to fit the postwar U.S. data. The role of technological progress in the household sector and shifts in the wage structure for explaining these facts is gauged.
