Curriculum Vitae (CV)

  • Experimentelle Wirtschafts­forschung

    Die experimentelle Ökonomik ist vielleicht die aufregendste methodische Innovation in den Wirtschafts­wissenschaften in jüngerer Zeit. Volkswirte führen Experimente aus dem gleichen Grund durch, aus dem Physiker oder Chemiker dies tun: Um etwas sehr sorgfältig unter kontrollierten und sauberen Laborbedingungen zu erforschen. Der einzige Unterschied ist, dass der Gegenstand der Untersuchung nicht ein subatomares Teilchen oder eine chemische Substanz ist, sondern menschliches Entscheidungs­verhalten. Experimentalökonomen stellen Versuchspersonen also vor Entscheidungs­probleme und beobachten dann, was sie tun. Wichtig dabei ist, dass die Entscheidungen, die die Teilnehmer fällen, reale monetäre Konsequenzen für sie haben; es geht also um echtes Geld.

    In der experimentellen Wirtschafts­forschung betrachtet man ein breites Spektrum an Entscheidungs­situationen, die durch ganz grundlegende wirtschafts­wissenschaft­liche Fragen motiviert sind. Zum Beispiel: Wie verhalten Menschen sich, wenn sie mit „Risiko“-Situationen konfrontiert sind, in denen besonders gute, aber auch sehr ungünstige Ergebnisse möglich sind? Unter welchen Umständen und in welchem ​​Ausmaß beeinflusst das Streben nach Fairness oder Status wirtschaft­liche Entscheidungen? Worum genau geht es den Leuten dabei, und wie robust ist das? Inwieweit und in welcher Weise verhalten Menschen sich strategisch? Welche Faktoren bestimmen die Wettbewerbsintensität von Märkten? Was sind die wahrscheinlichsten Ergebnisse in unterschiedlichen Verhandlungs­situationen? Der experimentelle Ansatz hat sich als sehr erfolgreich erwiesen, um unser Verständnis hinsichtlich solcher Fragen zu verbessern.

    Der experimentelle Ansatz ermöglicht es Forschern, Dinge zu tun, die mit der herkömmlichen Analyse von Felddaten schwierig zu erreichen sind. Zum Beispiel kann man Kontrafaktisches erkunden („Was würde passieren, wenn ...“), man kann quantifizieren, wie nah tatsächliche Ergebnisse (z. B. beobachtete Preise) und wünschenswerte Ergebnisse (z. B. effiziente Preise) beieinanderliegen, und man kann Ursache und Wirkung separieren. Auf diese Weise ergänzen Laborexperimente Felddaten-Untersuchungen und haben sich als wichtige Informations­quelle erwiesen, um ökonomische Theorien zu verbessern. Gelegentlich führen Volkswirte auch Feldexperimente durch. Dahinter steckt der Versuch, die Vorteile der Feld- und Laborforschung miteinander zu kombinieren.

    Experimentelle Forschung hat teilweise auch direkten praktischen Nutzen, denn sie ermöglicht es Ökonomen und Entscheidern in Firmen und Organisationen, die wahrscheinlichen Folgen neuer Regeln abzuschätzen, bevor diese in die Praxis umgesetzt werden. Beispiele für diese Art von „Windkanal“-Experimenten sind das Design neuer Märkte, bessere Regeln für die Allokation knapper Ressourcen, effektive Anreizsysteme, neue Formate für Auktionen und Abstimmungs­regeln oder sogar die Entwicklung wirkungs­vollerer Mechanismen, um Spenden für gemeinnützige Zwecke zu einzuwerben.

    In den bedeutendsten und faszinierendsten Beiträgen zur experimentellen Ökonomik geht es jedoch um elementare Fragen hinsichtlich der Grundpfeiler ökonomischer Theoriegebäude. Experimente erlauben es uns, sehr präzise zu untersuchen und zu hinterfragen, wie Menschen Entscheidungen in wirtschaft­lichen Kontexten fällen. Wie sich dabei auch zeigt, sind manche der Befunde aus der experimentellen Forschung durchaus unbequem für Wirtschafts­wissenschaft­ler. Sie werfen z. B. ernste Fragen hinsichtlich der Legitimität des traditionellen Konzepts des „Homo Oeconomicus“ auf, selbst als grobe Approximation von tatsächlichem Verhalten. Über die Jahre hat dies bereits teilweise zu einer schrittweisen Veränderung geführt in der Art und Weise, wie volkswirtschaft­liche Modelle konstruiert und gerechtfertigt werden. Es gibt eine Debatte darüber, in welchem Ausmaß Modelle auf empirisch besser fundierten Annahmen fußen sollen. Auf diese Weise hat mithilfe der experimentellen Forschung eine spannende Erneuerung der Volkswirtschafts­lehre eingesetzt.

    Interessiert? Die Abteilung VWL an der Universität Mannheim bietet in ihren Bachelor- und Master­programmen verschiedene Kurse zur experimentellen Wirtschafts­forschung und verhaltens­orientierter Ökonomik an. Darüber hinaus betreibt die Abteilung ein eigenes Forschungs­labor, in dem regelmäßig experimentelle Studien durchgeführt werden: mLab.

  • Teaching (current semester)

    E 801: Advanced Microeconomics II - Spring 2018

    Lecturer: Prof. Dr. Henrik OrzenProf. Takakazu Honryo, Ph.D.

    The module consists of two parts. The first part (Honryo) covers the theory of general equilibrium. The goal is to introduce the basic concepts and tools in the field and to facilitate your transition from undergraduate study to your own research.
    The second part (Orzen) covers essential topics of behavioral and experimental economics.

     

    BE 511 Business Economics 2 - Spring 2018

    Lecturer: Prof. Dr. Henrik Orzen

    Problem classes: Paolo Conteduca, Vahe Krrikyan, Chia-Yu Tsai, Niccolò Lomy

    Building on BE 510 Business Economics 1, this module provides an introduction to economic models of strategic decision-making and behavior of firms in the context of oligopolistic competition. Topics include output and pricing strategies, the economics of collusion, market structure, market entry decisions and product differentiation. Some of these topics require a degree of analytical rigor and we will make use of some game-theoretical and mathematical methods.

    Exam script viewing will take place on Tuesday, 24th July (2 p.m., 2:30 p.m, 3 p.m., 3:30 p.m. and 4 p.m.) and on Wednesday, 25th July (9:30 a.m., 10 a.m, 10:30 a.m., 11 a.m. and 11:30 a.m.).  Please send an email to our office (Friederike Pipphardt) to book a place if you would like to have a look at your exam.

     

  • Teaching (former semesters)

    2016/2017

    BE 510 Business Economics 1 - Autumn 2017

    Lecturer: Prof. Dr. Henrik Orzen

    Problem classes: Ms Chia-Yu Tsai, Mr Francesco Paolo Conteduca and Mr Xijian Su

    This module will start with a brief review of standard models of choice, including choice under risk, and then move on to an extended introduction to non-cooperative game theory. Strategic decision making and relevant solution concepts for games of complete and incomplete information will be covered in detail. The course will close with a discussion of basic notions in the economics of information. An important aim is to convey an understanding and a working analytical knowledge of how economists model decision making.

    E878 Advanced PhD Seminar in Experimental Economics - Fall 2016

    Seminar convenors: Prof. Dr. Henrik Orzen and Prof. Stefan Penczynski, PhD.

    In this seminar participants present and discuss their current research as well as ideas for future research. If you are interested in the seminar, please contact one of the seminar convenors by email.

     

    E883 Topics and Projects in Experimental Economics - Fall 2016

    Lecturers: Prof. Henrik Orzen and Prof. Stefan Penczynski

    This module intends to introduce PhD students to current topics in Experimental and Behavioral Economics and to familiarize them with recent advances in the field. The course will be delivered via a mix of lectures, joint readings of papers, in-class discussions and project work. The lectures will provide introductions to various topics and give relevant background information. Selected papers from the recent relevant literature will be discussed in depth. For this to work all participants will have to read specific papers in advance of individual meetings. Over the course of the semester each student is expected to lead the in-class discussion of two of the papers. The module will also provide a forum for students to discuss research ideas and preliminary work. In fact, students are expected to develop a research project of their own and present their advances, experimental design or data. This can be done individually or in pairs.

    Biases in economic decision making - Block seminar - Spring 2016

    Seminar convenor: Prof. Dr. Henrik Orzen

    This seminar introduces students to a range of empirical and experimental findings that indicate systematic biases in human decision making. While our brains can perform many complex tasks, there is evidence that humans tend to commit specific cognitive errors in certain types of situations. Sometimes, such evidence is debated controversially in the literature. Several topics from this area will be discussed in the seminar.

    The course will be held as a block seminar on Friday, 19 February, and Friday, 4 March. The seminar is targeted at advanced undergraduate students. To register you must have completed Microeconomics B (or equivalent). The course language will be English.

    Criteria for assessment are active participation, a presentation, a handout and a seminar paper.

    A list of topics can be downloaded here. If you wish to take part in the seminar, please send an e-mail to Ms Reiter. The registration period is from 22 to 27 November 2015. Please name your three most-preferred topics in your application. You are also welcome to propose a topic yourself. In that case please get in touch with Professor Orzen. We will employ a first-come first-serve approach (e-mails arriving before the registration period will be disregarded). Should the seminar be full we will inform you and add your name to a waiting list. Please inform us if you are no longer available.
