Book excerpt: Bringing together imaginative architectural approaches with texts by key contemporary thinkers, the two-part Informal Market Worlds explores new ways to interrupt the dominant logics of neoliberal governance. The Reader includes expert essays on urban informality, bottom-up economies and informal architectures as harbingers of social and political change. Offering a global perspective on the conflicted realities of informal marketplaces--from survival activities of the urban poor to transnational clandestine trade networks--these analyses reveal how informality has become a political instrument in the struggles around global market integration.
