Abstract:
It is probably the most important issue in economics. How do economies grow? And for a few centuries, one traditional model has prevailed. Economies grow through specializing in industries, through division of labor, and through standardization. But one of the leading thinkers of our time, the urban scholar Jane Jacobs, has long emphasized the importance of diversity and variation to growth. The author summarizes her views and the empirical evidence and finds that Jacobs' ideas also have serious policy implications.
