Labor Economics Bonn Graduate School of Economics SS 2000 Magnus Lofstrom Klaus F. Zimmermann Students interested in the below described graduate level course in labor economics should attend the meeting on Friday March 31 at 13:00 to discuss the course, proposed syllabus and meeting times, in IZA's seminar room. The principal objective of this course is to introduce students with research interests in labor economics to several key theoretical and empirical issues in the field. The course will focus on 7 general topics: labor demand, labor supply, human capital, wage setting institutions, labor mobility, unemployment and earnings inequality. The course will be divided into 2 parts. The first part consists of 8 lectures covering the topics listed above. Each lecture will be for 3 hours. Students are expected to have done the readings in advance and to be active, i.e. ask questions and to participate in discussions of the topics, during lectures. The date and time of the lectures are listed by the respective topic. The second part of the course consists of sessions led by the students. In each session students will be assigned to present a review and critique of the respective literature on specific topics. The topics will be decided on early in the course and may be within the proposed general topic of Earnings Inequality. All participants will discuss the presentations. A partial list of references on this topic can be found below. The presentations will take place July 10 and 11. Prerequisites: Sound understanding of microeconomics and econometrics. Text: Ehrenberg, Ronald G. and Smith, Robert S. (1996), Modern Labor Economics: Theory and Public Policy, Sixth edition, Addison-Wesley: New York. This is an introductory text in labor economics. The course will extensively use journal articles to supplement the topics covered in lectures. It is highly recommended that students read the assigned chapters before the course starts. 1 Examination: The examination for the course consists of your presentations and participation in the discussions in the course. Furthermore, you have to write a short term paper (10-15 pages in English) on one of the topics discussed in the lectures. The paper has to be written individually and must be submitted at the end of the semester. There will also be a written in-class exam at the end of the first part of the course.
