Productivity and Value takes a critical look at the "generic" concepts of productivity as they are used in most of the conventional literature. In this compelling book, the author challenges the concept of "total-factor" productivity as a valid indicator of successes or failures in economic policy and in the economy generally. Unique to this book is the consistent distinction made between economic and physical expressions. The author examines the difficulties when physical and economic measures are mixed. Instead, he proposes that productivity, as a measure of progress in production, should be limited to single-factor of key commodities, such as land, labor, energy, and capital. Such a measure, he claims, will be more realistic and will also come closer to being understood by the public.
