“…Such research has often been guided by analyses of what is called human capital, or the investments that people make in themselves to improve their skills and abilities (Becker, 1964;Ben-Porath, 1967;Mincer, 1997). With the assumption that job market outcomes reflect inputs in the investments in education and experience, a great deal of the research on labor market inequality within the US context has been on determining the differences in the education and experience of various categorical groups (e.g., women and racial minorities), whether the education and experience that they have pays off in the same way or to the same extent, and whether the access to and quality of education and experience are equally available to different social groups (Aigner & Cain, 1977;Becker, 1985;Bendrick et al, 1991;Bielby & Baron, 1986;Bridges & Nelson, 1989;Browne & Misra, 2003;Campbell, 1988;Castilla, 2008;Cotton, 1988;Darity & Nembhard, 2000;Fairlie & Kletzer, 1998;Holzer, 1994;Massey, 2007;Reskin, 2000). Although this research often highlights the importance of information available through social connections and the relative importance of formal versus informal job search channels, the role of social networks in the job search process has been thought more as a side issue than as the foundation of job market processes within the US.…”
