This book analyses three key aspects of microfinancing, namely social purpose, commercialization and innovations and examines, through a global perspective, how these aspects helped and diverted microfinance institutions towards the attainment of their dual goals over the last twenty years. Since microfinance remains informal in nature for most economies, not all financial innovations are suitable for its needs. Hence, the arguments in the book put forth an important challenge to the advocates of innovations and subsequently highlight why MFIs should be cautious when integrating innovations to ensure its original promise. The book is based on empirical analysis by utilising the latest and global microfinance market data, rather than focusing on a specific region. Thus, the book bridges a gap in knowledge by unravelling detail of the social purpose, commercialization and innovations within the field of microfinance and will be a valuable resource for those exploring the dynamics of innovations in microfinance.
