Cities like Tokyo, Seoul, Singapore, and New York all have high-density living, yet they do not exhibit the same divergence between satellite-observed light and reported GDP. If urban density were the primary cause of the mismatch, it would appear across both democratic and authoritarian countries.

Similarly, gains in energy efficiency, such as widespread LED adoption, are global and not limited to any regime type. The same applies to economic transitions from heavy industry to services and behavioral shifts toward indoor or screen-based activity; these are common across modern economies. However, the study finds that the light/GDP mismatch emerges selectively in authoritarian regimes once they pass the income threshold for certain types of foreign aid.

This pattern suggests that the divergence is not driven by modernization effects alone, but rather by systematic incentives to inflate economic data.
