Thaler and Harvard Law School Professor Cass R. Sunstein, first published in 2008. The book draws on research in psychology and behavioral economics to defend libertarian paternalism and active engineering of choice architecture. The book received largely positive reviews. "The Guardian" described it as "never intimidating, always amusing and elucidating: a jolly economic romp but with serious lessons within." It was named one of the best books of 2008 by "The Economist". One of the main justifications for
Daniel B. Klein by Cass Sunstein and Richard Thaler, as oxymoronic. He argued against what he perceived as an overly loose and weak definition of libertarianism on the grounds that Thaler and Sunstein made no meaningful distinction between liberty and coercion. In failing to define the concepts of liberty and coercion as fundamentally dissimilar processes. Libertarian paternalism uses a hyperrational behavior model of human nature as a definition for libertarianism, and neglects alternative definitions such as those advanced by Adam Smith and F.A. Hayek. Daniel B. Klein Daniel Bruce Klein (born January 16, 1962) is an American professor of economics at George Mason
