The findings of an Italian young and talented scholar
The book examines job trends in metropolitan areas of the United States and shows that Americans with high school degrees who work in communities dominated by innovative industries (identified by Prof. Moretti as "brain hubs") actually earn more than the college graduates working in communities dominated by manufacturing industries.
Prof. Moretti clarifies also the rationale behind such trends, identifying three main reasons to explain the creation of Brain hubs. The first is related to the thick labor market effect; the second to the high specialization of providers of intermediate services; the third to what economists call human capital spillovers.
As James Pressley from Bloomberg Businessweek points out, the book offers persuasive look at why some U.S. cities have prospered in recent decades while others have declined: by doing so, it demonstrates how essential it is for individuals to be highly mobile in pursuit of the best employment opportunities. The lessons of the book can be easily applied outside the U.S., as the author establishes a parallelism between what has happened there and what is happening elsewhere: according to Prof. Moretti, "the best news of the last 20 years globally is the vast increase in the standard of living in places like China and India and Brazil", but with a closer look "you see the same great divergence that you see" in the Western world.
Prof. Moretti graduated from Bocconi University in Milan and is Professor of Economics at the University of California, Berkeley. He also collaborates with the London School of Economics and Oxford, Cambridge and Bonn Universites. His main research interests include Labor Economics, Urban Economics and Applied Econometrics.
