In this new, greatly updated edition of The Return of Depression Economics, Krugman shows how the failure of regulation to keep pace with an increasingly out-of-control financial system set the United States, and the world as a whole, up for the greatest financial crisis since the 1930s. He also lays out the steps that must be taken to contain the crisis, and turn around a world economy sliding into a deep recession. Brilliantly crafted in Krugman’s trademark style-lucid, lively, and supremely informed – this new edition of The Return of Depression Economics will become an instant cornerstone of the debate over how to respond to the crisis.
