These guides are short summaries of the backbone papers from the second half of the course. They are written for students who have had intermediate microeconomics but only limited econometrics. The goal is not to replace the papers. The goal is to help you read them with a clear sense of the question, the strategy, the main result, and why the paper matters for class.
I focus on the core research papers from Lecture 11 onward and skip the podcast, web primers, and short background pieces. Each guide is intentionally short enough to be read before class.
