Abstract
Aggregate consumer and producer surplus is a special type of social welfare function. In this paper, we investigate how individual welfare weights and how the social marginal utility of an increase in an individual's income behave if one uses aggregate surplus as a measure of social welfare. Our conclusion is that aggregate surplus is an ethically unacceptable measure of social welfare.
