In this book, Jane Jacobs, building on the work of her debut, The Death and Life of Great American Cities , investigates the delicate way cities balance the interplay between the domestic production of goods and the ever-changing tide of imports. Using case studies of developing cities in the ancient, pre-agricultural world, and contemporary cities on the decline, like the financially irresponsible New York City of the mid-sixties, Jacobs identifies the main drivers of urban prosperity and growth, often via counterintuitive and revelatory lessons.
