This book examines a number of aspects of the process of structural change during development and, unlike most previous books on the subject, emphasises the role of service activities. A large and growing share of resources devoted to the service sector is shown to be a widespread phenomenon among both developed and less developed countries. It is argued that it is important to distinguish between government-provided services and those sold through the 'market', if their role in the growth process is to be properly understood. A detailed case-study of the growth of these services in Egypt is presented. This book also highlights the importance of growing tax revenues to finance expanding public services in many countries.
