Economic restructuring in the United States has taken many forms over the past few centuries, and the rise and fall of different regions can be charted by looking at some of these staggering changes. One well-known story is the transformation of Massachusetts in the past century as many cities in the state went from traditional industrial powerhouses to finding themselves with high levels of unemployment and in economic decline. This fascinating report from the Brookings Institution takes a look at some of these cities (such as Worcester), which have struggled in recent decades to reinvent themselves as centers of other economic activity. This 68-page report, published in February 2007, discusses how Worcester and other "gateway cities" might be rejuvenated through a sustained commitment on the part of various government entities and private corporations.
