A caliper mechanism is a common tool used to prevent from inexact matches. The existing literature discusses asymptotic properties of matching with caliper. In this simulation study we investigate properties in small and medium sized samples. We show that caliper causes a significant bias of the ATT estimator and raises its variance in comparison to one-to-one matching.

Mechanizm obcięcia (suwmiarki) jest szeroko stosowanym narzędziem zabezpieczającym przez słabo dopasowanymi połączeniami. W literaturze opisywane są własności asymptotyczne estymatorów z obcięciem. W artykule opisany jest eksperyment symulacji numerycznej badający własności tych estymatorów w małych i przeciętnie liczebnych próbach. Pokazujemy, że mechanizm obcięcia (suwmiarki) powoduje znaczne obciążenie estymatora przeciętnego efektu oddziaływania wobec jednostek poddanych oddziaływaniu (ang. ATT) i wzrost wartości jego wariancji w porównaniu ze standardowym estymatorem 1:1.
