This book explores the major elements underlying this approach to microenterprise finance, and evaluates various methodologies to provide financial services to the poor. The final section is devoted to case studies of Bank Rakyat Indonesia, BancoSol (Bolivia), the Association of Solidarity Groups (Colombia) and the Kenya Rural Enterprise Program.
