Along with construction of the joint hypothesis of efficiency and equilibrium, this has resulted in a generally accepted theory of financial markets where risk is made benign (i.e., a mildly perturbed certainty) in order to achieve analytical tractability, and where acceptance of the neoclassical model is a test of faith. In fact, the authors argue, this theory is a massive edifice built on a pile of assumptions, presumptions, and ignored evidence, whose practical results range from the LTCM collapse to the dot-com bubble to Enron. %U https://jpm.pm-research.com/content/iijpormgmt/29/3/91.full.pdf
