More than any of his predecessors in the White House, Franklin D. Roosevelt drew heavily on the thinking of economists as he sought to combat the Great Depression, to mobilize the American economy for war, and to chart a new order for the post-war world. Designs Within Disorder, published in 1996, is an inquiry into the way divergent analytic perspectives competed for official favour and the manner in which the President opted to pick and choose among them when formulating economic policies. During the Roosevelt years, two 'revolutions' were underway simultaneously. One of them involved a fundamental restructuring of the American economy and of the role government was to play in it. A second was an intellectual revolution which engaged economists in reconceptualizing the nature of their discipline. Most of the programmatic initiatives Roosevelt put in place displayed a remarkable staying power for over half a century.
