But history amply demonstrates that the only thing financial economics has in common with physics is that both have to leave by the law of what goes up must come down. Economics pretension of pure science. Businessweek International, Nov. 12, 1990. "...the purpose of neoclassical economics is "to demonstrate the social optimality if the real world were to resemble the model", not "to explain the real world as observed empirically". Neoclassical economics is unreal because it relies on mathematic models. "Neoclassical economics is also often seen as relying too heavily on complex mathematical models, such as those used in general equilibrium theory, without enough regard to whether these actually describe the real economy. Many see an attempt to model a system as complex as a modern economy by a mathematical model as unrealistic and doomed to failure. Famous answer to this criticism is Milton Friedman's claim that theories should be judged by their ability to predict events rather than by the realistically of their assumptions. Mathematical models also include those in game theory, linear programming, and econometrics. Critics of neoclassical economics are divided in those who think that highly mathematical method is inherently wrong and those who think that mathematical method is potentially good even if contemporary methods have problems. “But the amazing Japanese economy poses another challenge to received economic doctrine. Stated briefly and far too boldly, the Japanese have succeeded by doing everything wrong (according to standard economic theory). That should make economic theorists squirm. Studying the Japanese economy has led me to a tentative conclusion:that market capitalism, Japanese style, departs so much from conventional Western economic thought that it deserves to be considered a different system. As a top official of Japan’s fabled MITI once put: “We did the opposite of what American economists said. We violated all the normal concepts.” Businessweek International, Oct. 8, 1990
