Cheol-Sung Lee is an associate professor of sociology at the University of Chicago. He explores how leaders of labor and civic organizations in developing societies mobilize and institutionalize divergent repertoires of social solidarity regarding social policy agendas. He further studies how organizational leaders channel those policy agendas into state institutions through the politics of threat and persuasion. He develops a society-based explanatory model of the welfare state, in which labor-civic solidarity and union-party alliance jointly account for outcomes of welfare state retrenchment as well as welfare state expansion. This presentation will compare Latin America and East Asia.
