In this paper, we show that many semi-heuristiceconometric formulas can be derived from the natural symmetry requirements. The list of such formulasincludes many famous formulas provided by Nobelprize winners, such as Hurwicz optimism-pessimismcriterion for decision making under uncertainty, McFadden’s formula for probabilistic decision making,Nash’s formula for bargaining solution -as well asCobb-Douglas formula for production, gravity modelfor trade, etc.
