how much is the world richest economist paid monthly?

Question

who is he and what age

Answer 1

Wait a minute. You have misunderstood something about wealth.

The "world's richest" in a field having to do with economic factors in any way is not about the guy's salary, if he even has a salaried position. It's about his income from his own investments, based on his knowledge of the market forces that moves those investments.

It's not about what he's paid monthly. It's about where he puts his emphasis in his own stock portfolio.
