PUBLIC ECONOMICS LECTURES
Raj Chetty and Gregory A. Bruich
Harvard University
This is the first of two courses in the graduate public economics sequence at Harvard. This one-semester
course covers basic issues in the optimal design of tax and social insurance policies, with emphasis on
combining theoretical models with empirical evidence. Topics include efficiency costs and incidence of
taxation, income taxation, transfer and welfare programs, public goods and externalities, optimal social
insurance (excluding social security), and welfare analysis in behavioral models.
The course consists of 24 lectures, each lasting 1.5 hours. The slides and reading list are divided into
seven parts:
Part 1: Introduction
Part 2: Tax Incidence [3 lectures]
Part 3: Efficiency Cost of Taxation [3 lectures]
Part 4: Optimal Taxation [5 lectures]
Part 5: Income Taxation and Labor Supply [4 lectures]
Part 6: Social Insurance [5 lectures]
Part 7: Public Goods and Externalities [4 lectures]
We would like to thank Emmanuel Saez, Jon Gruber, Day Manoli, and many other colleagues whose
comments and lecture notes contributed to the development of these slides.
