In Social Movements and Radical Populism in the Andes: Ecuador and Bolivia in Comparative Perspective, Jennifer N. Collins examines why the new left took the form of radical populism in Ecuador and Bolivia and how social movements were impacted by this development. Using a Laclauian approach, Collins argues that anti-neoliberal social movements provided the groundwork for populist identity formation. This book also offers a nuanced and insightful explanation for the decline of Ecuador's indigenous movement, examining the role of state resurgence in the fragmentation of social movements. Collins’s analysis provides key insights into the life cycles of social movements in the Andes from development to decline.
