Book excerpt: With increasing assistance from the World Bank and other donors, microfinance is emerging as an instrument for reducing poverty and improving the poor's access to financial services in low-income countries. Providing the poor with access to financial services is one of many ways to help increase their incomes and productivity. In many countries, however, traditional financial institutions have failed to provide this service. Microcredit and cooperative programs fill this gap. They provide credit through social mechanisms such as group-based lending to reach the poor and other clients, including women, who lack access to formal financial institutions. Their purpose is to help the poor become self-employed and thus escape poverty. This book examines the experiences of the Grameen Bank, the Bangladesh Rural Advancement Committee, and the Bangladesh Rural Development Board's Rural Development Project-12 in order to quantify the potential and limitations of microcredit programs as an instrument for reducing poverty and delivering financial services to the poor.
