Geodesic Problem in Economic General Inequality

NOTICE

• just speculation, do not trust

MOTIVATION

• Toward "unified field theory of inequality" (Krugman)

PROBLEM

• how long time should be assumed for time horizon in such a too general macroeconomic growth model?
• it could be beyond the origin/doomsday of human nature and so beyond the scope of economic theory in usual sense, but it's not a problem
• the very problem is whether time horizon could be made finite or not
