Can a Composite Indicator Reliably Distinguish a Priority Dimension? A Two-Gate Screen and a Stylized Allocation Rule for Trade Logistics

This repository contains the replication materials for the manuscript entitled “Can a Composite Indicator Reliably Distinguish a Priority Dimension? A Two-Gate Screen and a Stylized Allocation Rule for Trade Logistics.” Supplementary File S1 contains the analysis panels, data provenance records, integrity flags, CRITIC weights, uncertainty decompositions, Gate 1 and Gate 2 results, calibration outputs, robustness analyses, corridor taxonomy, and a code manifest. Supplementary File S2 contains the Python code required to reproduce the analyses, tables, figures, simulations, and numerical results reported in the manuscript. The underlying primary sources are publicly available from the World Bank Logistics Performance Index and Worldwide Governance Indicators databases. The repository does not redistribute the WGI source data; it provides a retrieval script to reconstruct the panel from the original source.
