More by this authorSurvival of the City (with David Cutler)
Glaeser believes that the city is humanity's greatest invention and the key to the future of civilization. The power of the city comes from density: when people are close together, knowledge, ideas, and capital can flow quickly, and innovation happens as a result.
In the past, some predicted that technological progress would make face-to-face contact unnecessary and that cities would lose their meaning; but Glaeser points out that the opposite is true: the more knowledge-intensive the era, the more people need to be together. The data he cites show that workers in large metropolitan areas earn about thirty percent more than those who do not live in metropolitan areas; and a country's degree of urbanization is closely related to its wealth.
