Robert Prechter has written 13 books on finance, beginning with Elliott Wave Principle in 1978, which predicted a 1920s-style stock market boom. His 2002 title, Conquer the Crash, predicted the current crisis. Prechter’s latest interest is a new approach to social science, which he outlined in Socionomics—the Science of History and Social Prediction, published in 2003. In July 2007, The Journal of Behavioral Finance published “The Financial/Economic Dichotomy: A Socionomic Perspective,” a paper by Prechter and his colleague, Dr. Wayne Parker. Prechter has made presentations on his socionomic theory to the London School of Economics, Georgia Tech, MIT, SUNY, and academic conferences.
