From the Nobel Prize-winning economist and former chair of the U.S. Federal Reserve, a landmark book that provides vital lessons for understanding financial crises and their sometimes-catastrophic economic effects As chair of the U.S. Federal Reserve during the Global Financial Crisis, Ben Bernanke helped avert a greater financial disaster than the Great Depression. And he did so by drawing directly on what he had learned from years of studying the causes of the economic catastrophe of the 1930s-work for which he was later awarded the Nobel Prize. This influential work is collected in Essays on the Great Depression, an immensely influential account of the origins of the Depression and the economic lessons it teaches.
