What is social efficiency?
In this regard, what is a socially efficient quantity?
The socially efficient level of output is that quantity that maximizes the sum of the consumer and producer surpluses. It is the most efficient output level because the marginal social benefit of producing and consuming another unit equals the marginal social cost.
Simply so, who gave the concept of social efficiency?
However, an investigation of the origin of the term indicates that 'social efficiency' began its career in 1894 in the UK with the writing of Benjamin Kidd. From the outset, Kidd's social Darwinist position was disputed by sociologists and philosophers who interpreted the term from a humanitarian point of view.
Social cost includes these private costs and the additional costs (or external costs) associated with the production of the good for which are not accounted for by the free market. Mathematically, social marginal cost is the sum of private marginal cost and the external costs.
