PREREQUISITES: ECON-UA 11, ECON-UA 13, and ECON-UA 266
Prerequisites: V31.0011, V31.0013, and V31.0266. The course focuses on the role of market participants' expectations in driving risk and long swings in asset prices. Three approaches are discussed: the dominant Rational Expectations Hypothesis, behavioral-finance models, and recently proposed models of risk and fluctuations that place "imperfect knowledge" at the center of the analysis. Beyond comparing the three approaches from both the theoretical and empirical points of view, the course examines their implications for the reform of our financial system aiming to limit its vulnerability to future crisis.
