We extend the social entrepreneurship literature by introducing three types of sociocultural munificence for hybrid social ventures in an emerging industry sector: 1) social movement alignment, 2) social norms alignment and 3) political norms of needs versus merit-based resource allocation. Moreover we argue that the influence of sociocultural munificence on social entrepreneurs’ survival depends on overall economic munificence. Across a large multi-year panel of hybrid social entrepreneurship ventures we find the survival rate of social entrepreneurs is positively impacted by alignment with regional social movements and regional social norms. In addition, we find that political norms of needbased resource allocation insulate social entrepreneurs from negative economic conditions, whereas political norms of merit-based resource allocation amplify the impacts of economic munificence. Our theory and findings contribute to the entrepreneurship, social entrepreneurship, and organizational ecology literatures.
