Technological change, the increasing internationalization of national economies and the growing importance of activities that are hard to measure, such as services and financial transactions, limit the value of the old figures that count and weigh goods as they cross frontiers. Moreover, out-of-date statistical methods, limited funds, the lack of international comparability often make familiar data poor guides to policy. This volume takes a broad view of the problems, and emphasizes the need for figures based on the national ownership of companies and not just their location. ISBN 0-309-04590-8: $29.95.
