ABSTRACT
Charles Darwin had one bulldog to propagate his revolutionary theory, but John Maynard Keynes had three in America—Seymour Harris, Alvin Hansen, and Paul A. Samuelson. Literally hundreds of articles and dozens of books had been published about Keynes and the new Keynesian model since Keynes wrote The General Theory of Employment, Interest and Money. Samuelson is often regarded as the founder of modern mathematical economics after he wrote Foundations of Economic Analysis in the 1940s. The success of Keynesian economics and Samuelson's textbook reached its zenith in the early 1960s. Keynesian macroeconomics also became popular among journalists, because it was easy to understand, and among politicians, because deficit spending bought votes. The Robert Solow model attempts to determine the relative importance of varying determinants of growth, such as natural resources, population, capital formation, and technical progress. The Keynesian system assumes that the only thing that matters is current demand for final consumer goods—the higher the consumer demands the better.
