Lecture Plan

Format

The three hour evening session will be divided into two one-hour and twenty minute sessions each week. Ideally, the first part of each session will be a lecture on general issues; in the second part, we will discuss specific empirical studies relevant to these issues.

The Roy Model and the Generalized Roy Model

The Roy Model and its generalization are basic tools of applied economics and econometrics. I will draw on your knowledge of it in this course. Economics 312 and other courses teach this model. It helps you interpret the statistical estimates reported in many applied papers estimate in terms of well-posed economic models instead of ill-defined “effects.” For background and review, see

The following short documents explain key ideas.

  1. Notes on Roy Models and Generalized Roy Models
  2. Roy Models of Policy Evaluation
  3. The Normal Generalized Roy Model
  4. Notes on Identification of the Roy Model and the Generalized Roy Model

Grading

Students taking the class for a grade are asked to present reports on groups of related articles supplementing the lectures. Topics must be aligned with the lecture of the day, and coordinated with the instructor and the TA. Students may form groups to prepare reports. Group size is limited to three. Topics for reports and reports themselves will be screened in advance by the TA and the instructor. A list of eligible topics is below. Presentations should be scheduled by the second week, in conjunction with the TA and the instructor. Each report has to be rehearsed with the instructor and the TA. Slides have to be posted by Monday morning for a report on the following Wednesday. Reports will start as early as the third week. Third, fourth and and fifth week presenters who break the ice will get bonus points (20% for third week, 15% for fourth week, and 10% for fifth week). Reports count for 30% of course credit, homework counts for 30%, a take-home final counts for 30% of the grade, and classroom participation counts for 10%. The instructor will call on students during class.
