<i>'. . . the recent volume by Professors Hariolf Grupp and Shlomo Maital is a masterpiece, a book that may appear once in a generation. Only the quest for creativity brings scholars like them to work each day. . . The volume is an essential reading for both practitioners and academics. Hariolf Grupp and Shlomo Maital have delighted us with a long-awaited and formidable intellectually strong book that properly addresses the thorny issues of the economics of innovation in a new millennium. The volume is very well written. It is concise, well organized, with a clear flow of arguments and facts, leading to clearly stated conclusions. Each chapter includes an adequate self-contained summary. In each chapter we usually find a quantitative model that deals with the issues posed, but these models are not an obstacle for someone less mathematically savvy; on the contrary, the analysis is accessible to the general reader. The conclusions are substantive, follow from the analyses, and offer remarkable insights. Most important though, the volume recently published by Professors Hariolf Grupp and Shlomo Maital invites us to embark on a spiritual journey. A journey in which human creativity plays a crucial role, by building and employing in various contexts a metrics of technological and productivity change. It is hard to think of a more exciting and worthwhile topic in applied economics.'</i>

<i>'The authors' methods of evaluating innovations are original and are of interest to people in business and management studies as well as economics. They are also useful to people in industry, especially the chapter on "benchmarking", brand names and building business models.'</i>
