Question

Quizplus · Accepted Answer

A social welfare function is a mathematical expression that seeks to represent the social well-being of a society as a function of the utilities of its members. It is not created by a specific department but is a theoretical construct used in welfare economics. Therefore, option A is incorrect. Also, a social welfare function can be derived numerically, so option C is not correct either. Option B correctly captures the purpose and essence of a social welfare function.
