BADM 791 Behavioral Economics Thursday, 7:00-9:45, AB 201 Professor Mark Pingle Office and Hours: AB 319C, Wednesday and Thursday 5:30-6:45 Fall 2012 Course Description: This course provides an introduction to behavioral economics, a branch of economics that stretches the economics discipline by relaxing its traditional assumptions, using ideas from psychology, sociology, and other disciplines. Course Objectives: This course will expose students to many of the ideas which have fallen under the behavior economics umbrella. For each idea considered, the objectives will be to: understand the basic theories (propositions about how the world works); review one or more relevant experiments (environments designed to reduce confounding) designed to test theories; review relevant empirics (data characterizing observed behaviors from experiments and from real world); review practical applications (how the idea can be applied in our daily lives, in business settings, or in framing public policy).

Grading Presentations: Topic Presentations (2 Assigned During Semester) Truth About Dishonesty written work and presentation Speed of Trust written work and presentation Term Paper: What is Behavioral Economics? Concept and Application Posts (Expectation: One per week average) Take Home Midterm In Class Final 10% 10% 10% 20% 10% 20% 20% Topic Presentations: Expectations and Grading The total presentation should last at least 30 minutes, but no more than 60 minutes The work load for each presentation should be roughly balanced among group members Each group member should participate in the presentation. Typically the presentation would be organized using powerpoint, but the presentation may include short videos or illustrations (e.g. an brief in class experiment) The focus of the presentation should be on o Identifying salient ideas, and explaining them in an understandable manner. o Identifying and presenting applications of the ideas, so people understand why the ideas are meaningful. 1 o The papers presented in the syllabus should be used as the primary source of content. However, students are encouraged to do a bit of extra research and add any particularly relevant content. Plus, students are encouraged to include applications they directly have observed or experienced in their own lives. The group should post a definition and an application for the most important key terms, so at least one post is made by each group member. Key terms not posted by group members should be listed on web campus and made available for others in class to post. Some written form of the in-class presentation should be posted electronically on webcampus, so all in the class have access to the written form. For the given presentation, each group member will submit a grade 2=C, 3=B, or 4=A for each of the other members, subjectively judging the overall contribution of each member. Immediately after hearing the presentation, each class member not in the group will submit a grade 2=C, 3=B, or 4=A for the quality of the presentation Using the class feedback and his own judgment, the professor will provide a grade for each member of the group, using the same grade for each group member as a starting point, but then adjusting grades for individuals based upon feedback from those within the group and based upon the professor’s perception of the quality of each individual’s effort. Book Presentations (Truth About Dishonesty and Speed of Trust) and Associated Written Work: The expectations are presented below, and the grading process will be the same as used for topic presentations. Students should obtain the books and begin reading them as soon as possible. As you can see below, each group will present a portion of each book. Term Paper: The term paper shall typed, double spaced, 12 font, with one inch margins, and no more than 15 pages of text. An additional cover page shall be added, which shall at least include the title “What is Behavioral Economics” and the student’s name. Additional pages for references should also be included, and the method of some journal of choice should be used as a model for citing sources and presenting references. The letter grade for the term paper will entirely be the professor’s subjective judgment of the paper’s quality. Concept and application posts: The expectation is that you should seek to post an average of once each week, or 14 posts for the semester. Each week, the presenting group should indicate the key terms they have identified and indicate who in their group is taking responsibility for posting the given key idea. Students not in the presenting group should look for key terms not identified by the presenting group, but related to the topic, or terms the group has identified but did not chose to post. When you find such an idea, simply post it, along with your name. You should accumulate your posts in a single document, which you will turn in on Week 13, November 15. Your grade for this work will entirely be the professor’s subjective judgment of the quality of your work. You should post your concepts and applications to the following “econwiki,” which is an attempt to accumulate some behavioral economics knowledge on the web. http://students.coba.unr.edu/econwiki/index.php?title=Main_Page You will need to create a log in account in order to be able to edit the wiki. Take Home Midterm: You will receive one question per week, related to the given topic. On week 8, October 18, you will turn in your answers to the first 7 questions. You may answer these questions individually, or in a group of up to 3 people. If you answer the questions as a group, you should turn 2 in one paper for the group, and in this case all in the group will receive the same grade. Your grade for this exam will entirely be the professor’s subjective judgment of the quality of your work. In Class Final: The questions for the final will be drawn from the course content presented in weeks 8-14. You will not know the questions in advance, and you will only be able to use the knowledge you have in your head. Your grade for this exam will entirely be the professor’s subjective judgment of the quality of your work. August 30---Week 1: What is Behavioral Economics?
