In Chapter 2 we focused on experiments in which the subjects have to choose between pairs of simple bets, where each bet is usually composed of only two outcomes. Statistical principles also play a role. Most economic and financial models, particularly equilibrium asset pricing models, explicitly or implicitly assume that investors are efficient and rational. They are comprehensive system of assumptions, hypotheses, definitions and instructions what should be done in a certain economic situation.
