Shift-Share Instrumental Variable (Bartik-instrument)
Det shift-share instrument, almindeligt kendt som Bartik-instrumentet, er en kausal-inferensstrategi, der konstruerer et instrument ved at interagere nationale eller sektorspecifikke chok (shifts) med lokale kompositionsvægte (shares). Dets moderne identifikationsramme blev fastlagt af Goldsmith-Pinkham, Sorkin og Swift (2020) og Borusyak, Hull og Jaravel (2022).
