"If the history of economics in the twentieth century were properly written, the two great figures associated with what has come to be called the Keynesian revolution would be John Maynard Keynes and Simon Kuznets. And this is a judgment in which Keynes would concur. Keynes showed in analytical terms the possibility of a shortage in aggregate demand and argued the means for its correction. But it remained for Simon Kuznets and his talented associates to put this in the quantitative terms that made it persuasive, indeed irresistible. The Keynesian argument could be resisted; the Kuznets figures could not."
