Microfinance is a major development tool in less-developed countries, and thus of vital concern for all contemporary studies of the social theory of development. The promises of microfinance extend far beyond increased income generation in developing countries, and its products and goals are diverse: health, housing, water and sanitation, education, climate change mitigation, and empowerment of women. There is a pressing need for a comprehensive volume that brings together different disciplinary, interdisciplinary, and scholar and practitioner perspectives on microfinance. The current volume aims to bridge this gap.
