Since 2008, economic policymakers and researchers have occupied a brave new economic world. Previous consensuses have been upended, former assumptions have been cast into doubt, and new approaches have yet to stand the test of time. Policymakers have been forced to improvise and researchers to rethink basic theory. George Akerlof, Nobel Laureate and one of this volume’s editors, compares the crisis to a cat stuck in a tree, afraid to move.
In 2011, the International Monetary Fund invited prominent economists and economic policy makers to consider the brave new world of the post-crisis global economy. The result is a book that captures the state of macroeconomic thinking at a transformational moment.
These two volumes bring together a set of important essays that represent a "new Keynesian" perspective in economics today. This recent work shows how the Keynesian approach to economic fluctuations can be supported by rigorous microeconomic models of economic behavior. The essays are grouped in seven parts that cover costly price adjustment, staggering of wages and prices, imperfect competition, coordination failures, and the markets for labor, credit, and goods.
