’Economists from all heterodox traditions of political economy will benefit from reading this book - both for its confirmation of many of the basic precepts of classical, Marxian and Harrodian economics and the challenges it poses for its trenchant Post-Keynesian/Kaleckian critics, for whom short-period analytics of effective demand can and should be extended to long-period analysis. While his critique of the principle of effective demand for the long run would leave many Post-Keynesians uncompromising, the strong Keynesian view held by the author on the necessity for public-sector capital budgeting, and a developmental state upon which ought to be grafted a long-term growth policy based on public investment would certainly find strong resonance in the context of the global economic crisis.'
