Hyunjoon Park recently posted a working paper (w/ Jae Kyung Lee) for the Population Studies Center Working Paper Series titled: "Growing Educational Differentials in the Retreat from Marriage among Korean Men." The paper explores "how men’s education affects their transition to first marriage, and how the relationship between education and marriage has changed across three 10-year birth cohorts of Korean men born from 1946 to 1975."
