The big picture: Regression Discontinuity
Can a cutoff create a local comparison that approximates random assignment?
Why a policy analyst should care
A treatment cutoff can create a credible local comparison, but the resulting effect concerns units near that cutoff and depends on continuity and nonmanipulation.
Follow the idea from the opening question to a practical decision. These are the conceptual moves this module will develop:
1 Question Can a cutoff create a credible local comparison?
2 Explore Assignment changes at a threshold
3 Formalize A discontinuity is the local effect
4 Transfer Audit a policy eligibility rule
