“…We consider a number of social outcomes with well-established associations with college attainment, employment, and earnings. Social attributes that we anticipate will largely associate with higher human capital include: number of close friends, due to the known advantage of social networks for employment (Jackson, 2009; Lin, 1999); marriage, due to the established association of marriage with employment and earnings, especially for men (Ahituv & Lerman, 2007; Bardasi & Taylor, 2008; Waite & Lehrer, 2003); and, personality and mental health, because they have been shown to associate with success at work and school (Fletcher, 2010; Hough & Oswald, 2000; Lagerveld et al, 2010; Lerner & Henke, 2008; Luo, Cowell, Musuda, Novak, & Johnsons, 2010; Spenner, 1988). Social attributes that we anticipate to associate with lower human capital include: cohabitation, due to some evidence of its correlation with lower attainment in school and at work (Cohen, 2002; Smock, 2000); and, sexual behavior and fertility, due to their correlations with less educational attainment and employment, especially among women (Braithwaite, Delevi, & Fincham, 2010; Budig & Hodges, 2010; Grogger & Bronars, 1993; Sibulkin & Butler, 2005).…”
