In this book, Sten Widmalm adopts comparative and empirical approaches to examine how decentralization is connected to social capital and corruption. Using evidence from in-depth field studies in Madhya Pradesh and Kerala, and analyzing it against historical cases from around the world, he presents theoretical perspectives and policy suggestions. Widmalm's journey takes him to ancient Rome, Greece and India, as well as to the West, China, Latin America, and Russia of more recent times.
