Qualitative Shock Mapping for Quantitative Production Network Models: Evidence from Iran-Related Hostilities
https://github.com/Wonseong620/Causal_Network_Map
The research question would be: "How can qualitative news about regional hostilities be converted into structured sectoral shock indicators, and how can these indicators supplement quantitative models of production network spillovers?"
In periods of regional hostilities, economic shocks are often observed first through qualitative evidence rather than official statistics. News reports, policy announcements, market commentary, and firm-level disclosures provide early information about disruptions, but this information is rarely organized in a form that can be directly used in quantitative models. This study addresses that gap by developing a news-based sectoral shock-mapping framework. The framework translates qualitative evidence into structured sectoral shock indicators, links them to input-output sectors, and uses dynamic network methods to examine propagation across the production system. The resulting approach serves as a supplement to quantitative modelling by improving the identification, timing, and sectoral allocation of geopolitical shocks.

- Language switches between the Arabic, Chinese, English, and Persian corpora (each ~170KB, loaded on demand).
- Correlation threshold (|r|) and Max lead day filter edges by the largest absolute lagged Pearson correlation within the lead window. Dashed orange edges indicate negative correlations.
- TY test significance restricts edges to those passing the Toda-Yamamoto Wald test.
- Edge display: Hover / selected node shows only edges incident to the hovered or clicked (locked) sector; the role filter isolates edges the sector leads or lags. Nodes are keyboard-accessible (Tab + Enter).
- Compare all (2 x 2) renders all four language networks under matched filters — the layout used for the four-language comparison figure in the manuscript.

data/v3/<language>.json — 50 ICIO V1 sector nodes and all 2,450 ordered sector pairs per language, with 7-day lagged correlations and Toda-Yamamoto test results (v3, raw volume series). An updated analysis (share-transformed series, BH-FDR edge selection) is in progress and will replace this dataset.
Edge row format: [source_v1, target_v1, ty_significant, ty_pvalue, ty_lag, r_lead1 ... r_lead7].
