of 'structural booms' explained US inflationless expansion in the late 1990s and claimed its transience. His papers develop the thesis that the great economic swings experienced by the West in the past century not only originate in non-monetary shocks but also operate fundamentally by non-monetary mechanisms. This book, as well as subsequent papers, argued that the fluctuation of unemployment rates in the United States, the United Kingdom, and France stemmed from the accumulation of wealth with minimal investment. In the mid-1990s, his research turned to what he called economic inclusion. He published in 1997 a book for the general public, Rewarding Work about the causes and cures of the joblessness and low wages among disadvantaged workers. Current focus Phelps's current work is about the benefits and sources of a country's structural dynamism: the enterprise and creativity of entrepreneurs, the skill of financiers in selecting and supporting the best projects, and the knowledge managers draw upon in evaluating and making use of new methods and products. Every dynamic economy has its doldrums and even torpid economies may rise, perhaps with delay, to an extraordinary opportunity. However, great dynamism, he argues, brings advantages in virtually every dimension of economic performance, not just in productivity. For Phelps, the challenges presented in a creative and evolving business sector provide most people with their main vehicle for the exploration, exercise, and development of their talents. In the already-advanced economies, that is perhaps the best reason that policy must aim to build a business sector of high dynamism and broad inclusion. The research task is to identify the institutions that are pathways to dynamism and the institutions that are obstructions. Phelps's own research on dynamism began at the European Bank for Reconstruction and Development in 1990 and 1992–93, where he worked on the theory of capitalism and issues of mass privatization in Eastern Europe. Later in the decade, he turned to studying a range of economic institutions in Western Europe and the United States. He conducted research with a focus on the Italian economy as Senior Advisor to Italy in Europe of the Consiglio Nazionale delle Ricerche from 1997 to 2000. In 2001, he and Roman Frydman founded the Center on Capitalism & Society at Columbia (now a unit of Arts and Sciences) to promote and conduct research on capitalism. In 2008, writing in the wake of the Great Recession, Phelps criticized the "false" models of
