| Outline of Final Research Achievements |
In a competitive market setting, the social evaluation process is formulated as an Arrovian social welfare function, and it is shown that there is no social welfare function satisfying the Arrovian three axioms. In order to derive a positive result, it is shown that logarithmic function is axiomatically derived as a consumer's cardinal utility function on money income levels, which implies that Eisenberg's consumer surplus measure can be characterized by the preference axioms. Moreover, the consumer surplus measures under risks are axiomatically analyzed.
