Labor Economics

Winter 2007

 

Course objectives

Labor economics, the study of labor markets, is a field populated by both micro- and macroeconomists. Broadly speaking, the questions we try to answer are "What determines differences in wages or labor supply between different people?" or "What determines differences in wages and labor supply between recessions and booms?". Traditionally, these questions have been approached with very different methods: largely data-driven (non-structural) microeconometrics on the one hand, and theory or model-based estimation on the other. But these differences are getting smaller and as a labor economist you need to be (somewhat) familiar with both views.

 In this course, we try to give you an overview of the field of labor economics, with a strong emphasis on theoretically motivated empirics or data-driven theory. We also tried to select topics that are at the edge of current research interests, so that you can start thinking about your own research topics. Since this is a second year Ph.D. course, the aim is not only to introduce you to the field, but also to prepare you to do your own research. For that reason, you will be evaluated not only in an exam, but also based on a research project that you present in class and write up as a paper (proposal).

 

Grading

In order to give you time to work on your project, we will try to concentrate the 'learning' part of the course in the first five weeks. This is reflected in the grading scheme. The first half will be concluded with a midterm exam, which counts for 40% of your final grade. The second half is evaluated on the basis of a shorter final exam early in the exam period (20%) and your project, due at the end of the exam period (40%). The grade for the project will be determined by your presentation in the last week of class as well as the final draft. Depending on the topic, your project is graded by Libertad or Thijs, but of course we will make sure that you neither benefit nor suffer from your choice.

 

Research project 

Your project may be either a critical evaluation of an existing paper related to the material covered in class or a research proposal for a paper of your own. In the first case, the paper should consist of a detailed summary of the article you are discussing, a critical evaluation of that article in the style of a referee report, plus a replication or extension of the results. If you decide to write a research proposal, you need to describe the contribution of your paper with respect to the literature, provide a detailed and precise description of the question you are planning to answer, plus show some preliminary results. In either case, the results may be empirical (cross-tabs, regressions) or theoretical (simulations, proofs). You will present your project in the last week of class, so that we can give you feedback on your idea.
