Nation’s natural global power

A lot of different algorythms have been proposed in order to calculate the global power of a nation. Some of them take into account a lot of parametres and are quite difficult to manage.

The Indian economist Arvind Virmani has proposed a simplified way to calculate the national power potential NPP as

NPP = P * y^a


  • P is the population
  • y is the pro capite GDP at purchasing power parity
  • b is a coeeficient whose estimate value is 1.5 to 1.6
