End-to-End Pipeline for Shift-Share (Bartik) Instrumental Variables // Construction, diagnostics, estimation, exposure- robust inference and publication-ready visualisation for shift- share (Bartik) instrumental variable designs, in one consistent workflow. Organised around the two identification routes of the modern literature. The exogenous share approach refers to Goldsmith-Pinkham, Sorkin and Swift (2020) doi:10.1257/aer.20181047 and the exogenous shift approach refers to Borusyak, Hull and Jaravel (2022) doi:10.1093/restud/rdab030 and Adao, Kolesar and Morales (2019) doi:10.1093/qje/qjz025. Wraps 'ShiftShareSE' for exposure- robust inference when available.
