These lectures are concerned with the origins of the distinctive policies of the Stockholm School of Economics, of which Erik Lundberg was a leading member. Lundberg explores the historical development of the Stockholm School and considers its place in the wider Keynesian tradition which dominated macroeconomic thinking in the West from the 1930s till the 1970s. The author examines the failure of Keynesian policies both in Sweden and internationally, and offers some tantalising and provocative remedies for future policy-makers to ponder.
