Regulation as a tool for pursuing equitable national development and the provision of adequate goods and services is an often enigmatic and inadequately understood subject. This book unravels the subject from theory to practice. It explains the rationale for, and objectives of, regulation in several economic sectors and addresses the policy, legal and institutional arrangements and mechanisms normally employed as well as the advantages and pitfalls of alternative approaches. The examples given elucidate these aspects not only on Tanzania and other African countries but also include cases from across the globe.
