The difference between game theory and traditional economics

The biggest difference is that game theory reflects that individual rationality does not necessarily lead to the maximization of group interests. Traditional economics believes that as long as everyone is rational, the interests of the whole society will be maximized under the action of the invisible hand.

Another difference is that the game theory holds that the information of both sides of the game may be asymmetric, and the acquisition of information is costly.

Traditional economics thinks that the information of participants is symmetrical and the cost of information acquisition is low.
