Abstract
The purpose of this study is to re examine decision making by an advanced economic theory. Although a large number of researches have been carried out on consumer education, they have lacked for the following:
1 arguments work in simplified model
2 problem identification and problem formulation are taken into consideration
3 consumers' decision making is interdependence, or consumer's behavior affects the others
4 incentive compativility constraints are taken into consideration.
So I use an advanced economic theory to solve these problems.
In concluding, I should emphasize that the application of the theory is indispensable for consumer education, because it is useful in solving these problems.
