This book's prime audience is government policy-makers. It provides a policy framework for governments to increase micro, small and medium enterprises' access to financial services - one which is based on empirical evidence from around the world. Financial sector policies in many developing countries often work against the ability of commercial financial institutions to serve this market segment, albeit, often unintentionally. The framework guides governments on how to best focus scarce resources on three things: developing an inclusive financial sector policy; building healthy financial institutions; and investing in information infrastructure such as credit bureaus and accounting standards. The book provides examples and case studies of how such a strategy has helped to build more inclusive financial institutions and systems in many countries.
