How does cooperation emerge in complex, diverse societies? Or rather, how do residents of diverse communities work together, despite the obstacles posed by racial/ethnic differences between them? To tackle these questions, Maria Abascal examines collective action across New York City neighborhoods that vary in terms of racial/ethnic and immigrant composition, socioeconomic resources, and residential stability. Maria C. Abascal is an assistant professor of sociology at Columbia University. Her ongoing projects explore the effects of demographic changes (real and perceived) on racial and policy attitudes, the consequences of diversity for collective action, and the stereotyping of Latinos and immigrants.
