The book begins with a commentary on the state of macroeconomics and an evaluation of attempts to redevelop its underlying vision of economic behaviour. Particular attention is paid to the treatment of expectations and anticipations. The second part of the book presents a behavioural framework which is compatible with an evolutionary perspective on economic behaviour. The third part of the book discusses the implications of adopting an evolutionary approach to macroeconomic theory, empirical methods and policy design, culminating in a specific policy proposal to cure stagflation.
