  1. What to Produce?
  2. How to Produce?
  3. Whom to Produce?

Economics is part science, part art. It combines elements of science but has too many variables and uncertainties to be a pure science.

“The ideas of economists and political philosophers, both when they are right and when they are wrong are more powerful than is commonly understood. Indeed, the world is ruled by little else. Practical men, who believe themselves to be quite exempt from any intellectual influences, are usually slaves of some defunct economist.”

John Maynard Keynes
