Erik Hurst 38001: Empirical Macroeconomics – Micro Data for Macro Models Fall 2009 Office: Email: Course Meeting: Office Hours: 410 Harper Center erik.hurst@ChicagoBooth.edu Thursdays, 6:00 – 8:40 (no break), Room C06, Harper Center By Appointment T.A. Laura Pilossoph (pilossoph@gmail.com) Overview The goals for this course are the following: (i) Introduce students to a variety of data sources which can be used to test and calibrate models which are of interest to macro economists. (ii) Introduce students to important papers and research areas that are primarily empirical in nature and which have made fundamental advances to areas of interest to macro economists (broadly defined). (iii) Get students to think hard about the genesis of research questions and the inputs into successful research. Course Requirements There is a lot of work in this course. Hopefully, all of it will be beneficial with respect to sharpening your research skills. Aside from attending class, doing the course readings, and participating in lectures, you will have three additional requirements: handing in homework assignments, replicating an existing paper, and writing an original “virtual” paper. Below I discuss these requirements. Note: Auditors are expected to complete some components of the weekly assignments (those relevant to class discussion). (1) Weekly assignments (5 out of 9 weeks). The weekly assignments will have three components. All assignments should be done individually. A. Two page “referee reports” (max) on assigned papers. Students will be required to critically assess selected papers and then be prepared to discuss both the benefits and potential limitations of the papers in class. The goal of these assignments is to get students to start critically assessing existing empirical research. Students should be prepared to discuss their report in class. 1 B. Small data projects. Students will be required to use various micro data sets to compute statistics of interests. The goal of these assignments is to get students to familiarize themselves with existing micro data sets. These projects will be discussed in more depth in class. The goal of these assignments is to get students familiar using empirical data sets. An example of an assignment would be: use the Panel Study of Income Dynamics (PSID) and document the time trend of real wages for low and high educated households from 1975 through 2005. C. Each week, I will provide students with a broad research question like “Why has the U.S. Savings Rate Declined?”. Most of these questions will not have a consensus correct answer. (The reason I will pick these questions is because I am not convinced of the available answers). Each week, students will have to provide a one to two page approach to answering such questions. In particular, students will provide a written hypothesis that can potentially explain at least part of the question at hand. Then, the students will provide a brief written discussion of how they could test their hypothesis in an ideal world and then how they might test it using potentially available data. We will allocate 15-20 minutes of each class to discuss these questions. Students should be prepared to discuss and defend their answers during class. All homework will be graded for effort. Much of these homework problems will not have one correct answer. However, the learning comes from struggling to think hard about how to approach the problems. In order to participate in the class, auditors are expected to complete parts A (referee reports) and C (short write ups to a research approach) of the weekly assignments. The reason for this is to foster interesting class discussions. Note: All questions on the homework should be directed to the T.A. (not me). I will handle questions on the paper requirements below. Laura will handle questions on the homework. (2) Paper replication. Each student will be required to pick a paper published in a top academic journal and replicate the main findings (you do not need to replicate the robustness tables or the minor tables – just the main findings of the paper). Four additional requirements are necessary. First, the paper has to have a substantial empirical component that uses micro data. Second, the paper must be of interest to macroeconomists (broadly defined). Third, you should try to choose a paper where the data and code were not made publically available by the authors (that would make this too easy). If you do choose a paper where the results were made publically available, you should proceed as if they were not made available. I want you to start with raw data and see if you can approximate the author’s main results. Fourth, you need to be able to get the data in its original form. You should assure yourself of these restrictions (particularly the fourth one) early in the process. In your write up, you should comment on how robust the author’s results were by exploring alternate specifications. As you will find, some results are surprisingly robust while others are very fragile. 2 Dates associated with the paper replication: Clear your paper with me by October 15th (week 3). There will be a sign up sheet in class during week 2. Each registered student will have a 15 minute meeting with me on 10/15 (Thursday) to go over their paper with me. Students should send me their proposed paper – via email - by 10/14 (Wednesday). Present a 15 minute overview of the paper in class on October 22th (week 4). No original work is necessary at this time. Just a presentation of the actual paper. What the paper tries to do, why it is interesting, what are empirical contributions, and how the empirical contributions were made. The class will then provide feedback about ways in which to explore the robustness of the paper’s conclusions. Your write up of the paper’s replication (including data and code) are due January 15 th. You should write it up as a replication (there is no need to rehash their literature review, their motivation, etc.). Your paper will discuss why you replicated that paper, why the paper is important (in your eyes), the data you used, how you constructed the sample, the methodology you used, your replication of the main results, comparing your results to the paper’s main results, and then exploring the robustness of the papers main results by examining alternate specifications. My estimates are that such replications should be roughly 20 pages (give or take) plus tables/figures. (3) Writing an original “virtual empirical paper”. This will be your main project for the course. It is a virtual empirical paper in that you do not actually have to generate the paper’s results. What I want you to do is to pick an original research idea and then develop how you would set out to empirically confront this idea. Your paper should take the following form: Introduction: What is the question and why is the question of interest? Literature Review: How does your paper fit into the broader literature? Theoretical Motivation: This could be actual theory or just a sketch of the relevant theory that underlies your question. Data: What data would you use to answer/address this question? Why would this data be ideal? Empirical Methodology: How would you use the data to answer your question? Remember to keep in mind the concepts of identification and causality along with the idea that the same set of empirical facts can often support many theories. Falsification Tests: Is there any other specifications that would either bolster or cast doubt upon your primary tests of your hypotheses. 3 No empirical work actually needs to be done for this project. I just want to get you to start thinking about potential original research questions. Your only restriction for this project is that the data has to conceivably exist. It doesn’t mean that the data actually has to exist – it just means that it could exist. For example, you can imagine conducting a survey that elicits the data that you need or, you can imagine getting access to classified household/firm data. Dates associated with the virtual paper. Clear your paper with me by October 29th (week 5). Again, we will have a 15 minute office meeting. Present your virtual paper in class on December 3rd. Most of the work for the paper needs to be done by this time. You should treat this as the due date for the conceptual component of the paper. I will give you more guidelines on your presentation as the quarter progresses. Your formal write up of the paper is due to me on January 15th. Your write up will incorporate the comments from the class that you received during your presentation. My sense is that the write up will be 15-20 pages (or so). Grading 40% of the course grade will be on the virtual paper (20% for the presentation and 20% for the write up). 30% of the course grade will be on the weekly assignments. 30% of the course grade will be on the paper replication. We will provide letter grades when grading the virtual paper (both components) and the paper replication. These will be based both on effort, originality/insight, and execution. We will provide √+, √, √-, 0 for the homework assignments (each component separately). These grades will be based solely on effort. Course Readings Each week in lecture, we will cover a different topic. I include many papers under the topics we are covering. These papers are designed to give students an overview of the (mostly) empirical papers that have contributed substantially to the literature at hand. Papers that I will cover in class are indicated with a (**). Papers that are particularly noteworthy are indicated with a (*). You should read all the (**) papers prior to class. All readings can be found online. Unless otherwise noted, you should read the published version. 4 Course Outline/Reading List Weeks 1 and 2: Household Consumption (A Thorough Reading List) Surveys of Consumption 1.
