"What on earth am I doing? What are we trying to accomplish as economic theorists? We essentially play with toys called "models". We have the luxury of remaining children over the course of our entire professional lives and we are even well paid for it. We get to call ourselves economists and the public naively thinks that we are improving the economy's performance, increasing the rate of growth or preventing economic catastrophes. ... As economic theorists, we organize our thoughts using what we call "models." The word "model" sounds more scientific than "fable" or "fairy tale" though I don't see much difference between them."    Ariel Rubinstein in Dillemmas of an Economic Theorist Freak-Freakonomics Ariel Rubinstein NEW INSTITUTIONAL ECONOMICS by Peter G.
