Most sociologists object to Paretian welfare economics because of its silence on the initial distribution of resources. It has also been argued that they constitute a rather weak basis for welfare judgements, since they explicitly forbid interpersonal comparisons, are concerned entirely with the subjective choices of individuals, and privilege the position occupied by the status quo (since any move from the status quo which was vetoed by one person would not be considered a Pareto-improvement). Since these assumptions are empirically questionable, and probably embody value-judgements about well-being and satisfaction, they are somewhat controversial. The principle rests on three assumptions: that each individual is the best judge of his or her own welfare that social welfare is exclusively a function of individual welfare and that if one individual's welfare is augmented, and nobody's is reduced, then social welfare has increased. ‘Pareto optimality’ is said to exist when the distribution of economic welfare cannot be improved for one individual without reducing that of another. A building block of normative economics and social choice theory, and often borrowed by contemporary political philosophy, the principle has rarely been subjected to philosophical criticism. A market exchange which affects nobody adversely is considered to be a ‘Pareto-improvement’ since it leaves one or more persons better off.
