This course is designed to provide systematic knowledge in behavioral finance. It concentrates on the irrational aspects of human behavior and their effects on investment and financing decisions. Key topics include the expected utility theory, the prospect theory, challenges to market efficiency, framing and mental accounting, heuristics and biases, overconfidence, rational managers, and irrational investors. After completing this course, students are expected to capture the limits of the arbitrage, challenges of the market efficiency, main assumptions and ideas of the expected utility theory and the prospect theory, and unusual phenomena that the classical financial theories have not been able to fully explain. Students could identify human behavioral biases and their impacts on the financial decisions of both investors and managers.
