WION Shock Model

Modeling shock propagation in the World Input-Output Network (WION) with damping and substitution effects.

What this repo does

• Builds IO matrices (Z, F, X, A, B) from ICIO-style SML CSVs
• Computes vulnerability and damping metrics (Vj, phi, d, D)
• Simulates shock scenarios and aggregates country/sector impacts
• Produces figures and tables for the thesis and presentation

Quickstart

1. Create and activate a virtual environment.
2. Install dependencies.
3. Run the scripts or notebooks.

python -m venv .venv
pip install -r requirements.txt
python main.py
