As the global economic crisis continues to cause damage, some policy makers have called for a more Keynesian approach to current economic problems. In this book, the economists Peter Temin and David Vines provide an accessible introduction to Keynesian ideas that connects Keyness insights to todays global economy and offers readers a way to understand current policy debates. John Maynard Keynes (1883-1946) created the branch of economics now known as macroeconomics. He played a major role in the reconstruction of Europe and the world economy after the Second World War. Keynesian economics came to be identified with efforts to mitigate the Great Depression and with postwar economic policies that helped power a golden age of economic growth. Temin and Vines argue that Keynes also provided a way to understand the interactions among nations, and therein lies his relevance for todays global crisis.
