channel_attribution

Channel Attribution — Table 5 (published contagionchannels). Per-crisis-episode attribution of cross-border contagion to five mutually exclusive transmission channels (Trade / Financial / Geopolitical / Behavioral / Monetary Policy), via the PUBLISHED contagionchannels package (Bhandari, Parida & Sahu 2026) — the paper's own two-stage pipeline (Stage-1 wavelet-quantile transfer-entropy detection + Stage-2 structural IV/2SLS attribution), not a reimplementation. Reproduces the paper's Table 5 over 8 episodes (PreCrisis…MidEastTariffs). Uses the package's BUNDLED data, not the g20 panel.
