Its central theme will be the “efficient market hypothesis” (EMH), one of the cornerstones of modern finance. The course will be made up of two parts: the limits to rationality in human financial decision-making, and the limits of markets to reach rational efficient equilibria. Special emphasis in this course is given to experimental studies. To deepen the knowledge and understanding of the functioning of financial markets, both paper and pencil and computerized market experiments are run during the course with near-to-reality market designs. In particular, the course consists of the following connected themes. The first part concerns some limitations to rationality. Psychological biases such as myopia, loss aversion, ambiguity aversion, present biasedness, etc, can lead to observed phenomena such as the endowment effect, the disposition effect, limited stock market participation or excessive risk taking. Some simple choice experiments will demonstrate these ideas and their effects. A second part investigates the efficiency of markets in general and drivers of bubble formation in financial markets in particular. Again, experiments will be run to detect environments which fuel or diminish bubbles on asset markets. Furthermore, the course sheds some light onto the performance of different groups of investors like insiders, mutual fund managers, etc. and thus covers the value of their private information. It will be investigated whether they are able to outperform the market which would mean that the market prices do not fully incorporate their information. Finally, experiments with asymmetrically endowed investors will be run and analyzed in class to observe differences in returns and behavior among the different trader groups. 1 GM1024, Behavioural Finance Michael Kirchler, Oege Dijk Learning outcomes Upon completion of the course the student will 1.

Grading 1. A written exam (learning outcomes 1-3) which accounts for 60% of the grade. At least 50% of the total points of the exam must be achieved to get a positive grade in the course. 2. Two mini-essays detailing an application of the concepts presented in class in the real world. (5% of the grade each). They will be presented in the last session of this course. 3. Group paper which include the group’s empirical or experimental study on financial decisionmaking or market efficiency (max. 3 students). Assessments 3 accounts for 30% of the grade. Group paper: Work together in groups of at maximum three. Try to find a research question on market efficiency (with special emphasis on experimental research questions) and conduct the study according to the principles of scientific work. The case study should be written like a “short” scientific paper and hence should serve as a good practice for writing your master thesis. The case study should contain the following sections: 1) Introduction and related literature Here you should briefly state what you are willing to look at (a very short summary of your research question) and you should shortly mention and explain related literature. Furthermore it is common practice in scientific papers to include a brief paragraph with your main findings that the reader already knows about the contribution of the paper from the beginning. The introduction is written in present tense (the part on related literature may sometimes also be written in past tense). 2) Research question and method The research question(s) should be deduced from existing literature which you presented in Section 1 and should be stated clearly. Furthermore you should explain your empirical model you test your research questions with in the subsection “method”. If you write your case study on experiments we conducted, you must also include a subsection on “model description” and explain the structure of the experimental market (see the experimental papers in the references of this course). This section is written in present tense. 3) Results Based on the research question, the results should be presented. Statistical tests should be traceable with the inclusion of p-values, sample size n, etc. The results section is written in present tense. 4) Conclusion and discussion This section should contain a brief summary of the research question, the method applied and the most important results. In the last paragraph it also makes sense to relate the results to existing literature and to discuss shortly the practical implications of your study. Writing in past tense is best suited for the summary of results. When discussing the results, present tense should be used. Of course, the case study must also include a full list of references and, if necessary, an Appendix with additional material. In total, the number of pages should be in the range of 10 to 15 (excluding the reference list and Appendices). 3 GM1024, Behavioural Finance Michael Kirchler, Oege Dijk Literature General Literature Shleifer, Andrei. 2000.
