On latitude and affluence: The equatorial grand canyon

  • Henri Theil
  • Janet Galvez
Short Paper


Our objective is to “explain” per capita GDPs by the countries' latitude, using PPP-based data for 138 countries in 1985 (PPP = purchasing power parity). A simple approach is formulated which nevertheless accounts for as much as two-thirds of the variance of the per capita GDPs.
