CEPII Gravity Dataset ingest. Source: http://www.cepii.fr/CEPII/en/bdd_modele/presentation.asp?id=8 Authors: Head & Mayer (CEPII) License: Free for research use Coverage: All country pairs, 1948-2019, bilateral trade gravity variables Key variables: dist (distance), comlang_off (common language), colony, contig (contiguity), gdp_o, gdp_d (origin/dest GDP), pop_o, pop_d, tradeflow_comtrade_o/d (trade) fta_wto, gatt_o, gatt_d, wto_o, wto_d (trade agreements) lang_ethno, col_dep, col_dep_ever, etc. Gravity data is bilateral (country pairs), so series_key includes both countries. series_key: GRAVITY:{variable}:{iso3_o}:{iso3_d} e.g. GRAVITY:dist:USA:CHN Note: The full gravity dataset is large (1.4GB CSV). We fetch a compressed version or summary statistics to keep file size manageable. Output: data/clean_full/cepii_gravity/cepii_gravity.parquet Run: python jobs/ingest_cepii_gravity.py
