Homophily is the tendency of people to associate relatively more with those who are similar to them than with those who are not. In Golub and Jackson (2011), we introduced degree-weighted homophily (DWH), a new measure of this phenomenon, and showed that it gives a lower bound on the time it takes for a certain natural best-reply or learning process operating in a social network to converge. He...

Abstract In this paper we use a large overlapping generations model with individuals that differ across age and productivity to assess the effect of privatizing a pay-as-you-go social security system in two model economies. The first one is the standard model pioneered by Auerbach and Kotlikoff (1987) characterized by the perfect substitutability in production of individuals with different expe...

We develop a model where agents obtain information about job opportunities through an explicitly modeled network of social contacts. We show that employment is positively correlated across time and agents. Moreover, unemployment exhibits duration dependence: the probability of obtaining a job decreases in the length of time that an agent has been unemployed. Finally, we examine inequality betwe...

Network research about employment outcomes has rarely focused on women. In this paper, we use the Los Ž . Angeles Survey of Urban Inequality LASUI to examine the role of social networks on the constraints and opportunities which women face in labor force participation. We examine the effects of a woman’s general network structure on her employment status, rather than focusing on the characteris...
