ABSTRACT
Chapter 6 summarises some of the results of the book. It explains how the intent of this book is not to side with heterodox economics against the mainstream conception of GDP and economic growth. Various theories and measures serve their purposes. Important issues concern how to deal with coercion, double counting, self-reference of transaction costs, human capital formation and non-market activities. It presents the various definitions of the production boundary of this book, most important non-social and comprehensive production. The chapter discusses whether overly formalised and too exact definitions can be counterproductive for science. It argues that the need for clear definitions for some scientific purposes must be made in recognition of, but not eclipsed by, the fuzziness of the world.
