Why
The value is knowing which assumption each method rests on — parallel trends, exclusion, continuity — so a policy claim can be graded by whether its assumption is plausible, not by its p-value.

#176PoC
Difference-in-differences, instrumental variables, and regression discontinuity recover causal effects from observational data, each buying identification with an assumption that is untestable and load-bearing.

이중차분(DiD), 도구변수(IV), 회귀불연속(RDD)은 관측 데이터에서 인과 효과를 복원하며, 각각 검정 불가능하고 하중을 받는 가정 하나로 식별을 사는 방식입니다.
가치는 각 방법이 어떤 가정 — 평행 추세, 배제, 연속성 — 에 기대는지 아는 것이고, 그래야 정책 주장을 p-값이 아니라 가정의 개연성으로 채점할 수 있습니다.
