Going beyond the usual state-centric approach to the study of the politics of neoliberal reform, Moises Arce emphasizes the importance of understanding the interaction between state reformers and collective actors in society. In Market Reform in Society he helpfully focuses our attention on how various societal groups are affected by different types of reform and how their responses in turn affect the state's subsequent pursuit of reform.

As a country characterized by strong state autonomy and widespread disintegration of civil society and representative institutions during the 1990s when Alberto Fujimori was president, Peru serves as an excellent case for examining how collective actors can succeed in influencing the reform process. Arce compares reforms in three areas: taxation, pension privatization, and social-sector programs in poverty alleviation and health decentralization. Differences in the concentration or dispersion of costs and benefits, he shows, affected incentives for groups to form and engage in collective action for supporting, opposing, or modifying the reforms.
