Sammanfattning	Regression discontinuity (RD) in sentencing exploits the sharp thresholds built into justice policy — sentencing-guideline cutoffs, the age of majority, risk-score thresholds that trigger detention or diversion — to estimate causal effects without a randomized trial. Units just above the cutoff receive a different treatment from units just below it, yet they are otherwise nearly identical, so comparing their outcomes isolates the effect of crossing the line. Berk and Rauma's 1983 evaluation of a crime-control program showed how criminologists can 'capitalize on nonrandom assignment' created by such rules.	Deterrence analysis studies how the threat and imposition of legal punishment discourage crime. Rooted in classical criminology and formalized in Gary Becker's economic model, it distinguishes the certainty, severity, and celerity of punishment, separates perceived from objective sanction risk, and uses quasi-experimental and perceptual evidence — synthesized by Daniel Nagin — to test how much, and through what channels, punishment actually deters.
