Economics, so they say, is eighty per cent psychology. In this book, the author shows that psychology is one hundred per cent economics. Every human interaction can be understood as a form of market economy. The theoretical explanation for this model follows from recent developments in systems and evolution theory and the epistemological concepts of so-called "radical constructivism".

Human behaviour can be seen as a commodity that is differentiated, named, evaluated and exchanged, and that means that anyone who acts, transacts. This book elucidates what this means in theory and practice for a manager and his everyday life, the organisation of companies, management, achievement, planning and business culture; the author illustrates this in a number of case examples and complements it with recipes for a manager's everyday life.
