Welfare economics is an approach to economic problems that is specifically oriented to the evaluation of the impact of various economic activities and measures on the well-being of individuals. It studies policy issues concerning the allocation of resources. Welfare economics, like medicine, is an applied science. It has to combine with other disciplines to show useful ways to structure and analyze issues. Welfare economics gathers together the pertinent theoretical relationships from positive to ''pure'' economics in terms, typically, of a single end: the economic welfare of the community (Rothenberg 1961).
