We propose the smooth transitions across latitudes and longitudes framework, a special case of the panel smooth transition regression, which allows the heterogeneity of coefficients based on countries’ geographic location. Using this framework we examine the effect of El Niño Southern Oscillation on economic growth. We find a wide range of effects spanning -4% to 3% per capita GDP growth rates across 137 countries. This finding can be of value to researchers in the fields of economic growth and climate econometrics.
