14.472: Public Finance II: MIT Fall 2020 Instructor: Amy Finkestein ([email protected]) Teaching assistant: Jonathan Cohen ([email protected]) Lectures: Monday/Wednesday, 2:30 pm-4:00pm, virtual Recitation: Friday, 12-1, location TBD Course description: The course focuses on government expenditures, specifically social insurance, and redistributive programs. Key topics include theoretical and empirical analysis of insurance market failures, the optimal design of social insurance programs, and the optimal design of redistributive programs. The department offers two graduate public finance courses: 14.471 (Public Finance I) and 14.472 (Public Finance II). Broadly speaking, 471 focuses on taxation while 472 focuses on expenditures. They may be taken in either order. Students who want to have public finance as a major field must take both 14.471 and 14.472. The course pre-requisites include the MIT first year graduate micro sequence (previously or in parallel) or equivalent coursework. Course requirements: 1. Written response papers: There will be 10-12 short written response papers due at 9 am on the day of each lecture. These written response papers should be 1-2 pages and briefly summarize the paper’s contributions as well as identify any flaws in the paper or questions that you may have. You are encouraged to think constructively, such as proposing additional data or tests that could address your concerns or alternative settings in which the methodology could be applied. These written responses count for 15% of the grade. 2. Required readings: To try to improve class discussion / facilitate participation in the on- line forum, there will often be additional required readings to complete prior to class. You will need to upload one paragraph (graded for completion only) by 1pm of the day of the class on a reading required for that class. The paragraph should identify a portion of the paper you had difficulty understanding along with your current interpretation of it. This will be 5% of the grade. 3. Problem Sets: There will be one problem set that counts for 10% of the grade. 4. Research proposal: There will be one assignment to pose a question motivated by the class and to design a randomized evaluation that could answer it. This will count for 20% of the grade. 5. Class participation: Active class participation is key for a successful learning experience. It will also count for 10% of the grade. 6. Final Exam: There will be a closed book 3 hour exam during finals week which will cover the entire course material and be worth 40% of the grade. Zoom norms: Teaching (and learning) on Zoom is challenging, and we are all on the relatively steep part of the learning curve. I very much want this class to be informative, interesting and engaging, and I welcome any/all real-time suggestions for how to improve the experience. As a start, please observe the following norms for lecture: 1. Camera on 2. Mute upon entry and when not speaking 3. Raise hand to speak or feel free to interrupt at any point 4. You will not be able to privately message other people except for Jon 5. It is difficult to stay engaged with a video, so please don't be shy about interacting with questions and comments! Your classmates (and I!) will all appreciate it. Course scheduling: • There will be no lecture Monday September 28 (Yom Kippur) but there will instead be a lecture during section on Friday October 2 (12-1). • Dmitry Taubinsky (visiting from UC Berkeley) will give two guest lectures on behavioral public finance (currently scheduled for October 19 and 21) 14.472 Home Page: There is a 14.472 site (https://canvas.mit.edu/courses/3464) on Canvas. Links for all of the required readings are included on the course website. All assignments should be submitted under the “Assignments” tab. Zoom links for lectures and recitations will be posted here. The Canvas page also links to Piazza (https://piazza.com/mit/fall2020/14472), which will be used for class discussion. Feel free to post questions on class materials, readings, or general research topics. Jon will respond, though you are highly encouraged to interact with classmates on the forum. Readings: Students are required to read the papers in bold before class. This is essential for the classroom lecture and discussion to be effective. Readings in italics are highly recommended for all students, especially those planning to have public finance as a major field. Office Hours: By appointment. Useful introductory / background texts: J. Gruber, Public Finance and Public Policy, 5th edition (New York: Worth Publishers, 2016) relevant chapters are 12-17 – We have posted these on the course web site.
