Each point on a social utility frontier represents an efficient allocation of an economy's resources; that is, it is a Pareto optimum in factor allocation, in production, in consumption, and in the interaction of production and consumption (supply and demand). In the diagram below, the curve MN is a social utility frontier. Point D corresponds with point C from the earlier diagram. Point D is on the social utility frontier because the marginal rate of substitution at point C is equal to the marginal rate of transformation at point A. Point E corresponds with point B in the previous diagram, and lies inside the social utility frontier (indicating inefficiency) because the MRS at point C is not equal to the MRT at point A. 1333:'s seminal paper in 1938, "A Reformulation of Certain Aspects of Welfare Economics." Bergson demonstrated that economic efficiency conditions could be precisely formulated without fully specifying the underlying social welfare function. By postulating W as W(UA, UB) and assuming W to be a positive function of each individual's utility, it was shown that maximum welfare occurred when allocative efficiency was achieved, and the marginal contribution to welfare of each individual was equalized. But this decision did not last long. In 1951, 2030: 324: 1882:, the change is desirable if the maximum the losers would be willing to offer the winners to prevent the change is less than the minimum the winners would accept as a bribe to give up the change. The Hicks compensation test is from the losers' point of view; the Kaldor compensation test is from the winners'. If both conditions are satisfied, the proposed change will move the economy toward Pareto optimality. This idea is known as 3500: 1151: 1652: 1381: 1268: 132: 3489: 1139: 36: 1903:. Hence, Pareto efficiency is a necessary, but not a sufficient condition for social welfare. Each Pareto optimum corresponds to a different income distribution in the economy. Some may involve great inequalities of income. So how do we decide which Pareto optimum is most desirable? This decision is made, either tacitly or overtly, when we specify the 234: 77: 1239:. The second theorem states that with further restrictions, any Pareto efficient outcome can be achieved through a competitive market equilibrium, provided that a social planner uses a social welfare function to choose the most equitable efficient outcome and then uses lump sum transfers followed by competitive trade to achieve it. 1356:

Note that if one of these conditions leads to inefficiency, another condition might help by counteracting it. For example, if a pollution externality leads to overproduction of tires, a tax on tires might restore the efficient level of production. A condition inefficient in the "first-best" might be

Until 1951, the objective of welfare economics remained largely uncontested. Economists viewed welfare economics as the branch of the discipline concerned with delineating the actions a governing body should undertake. It was commonly accepted that the term "maximizing welfare" held a specific

There are many combinations of consumer utility, production mixes, and factor input combinations consistent with efficiency. In fact, there are an infinity of consumption and production equilibria that yield Pareto optimal results. There are as many optima as there are points on the aggregate

Although all the points on the grand social utility frontier are Pareto efficient, only one point identifies where social welfare is maximized. Such point is called "the point of bliss". This point is Z where the social utility frontier MN is tangent to the highest possible social

To determine whether an activity is moving the economy towards Pareto efficiency, two compensation tests have been developed. Policy changes usually help some people while hurting others, so these tests ask what would happen if the winners were to compensate the losers. Using the

Questions of efficiency are assessed with criteria such as 1980:, though in general there is no reason to suppose that the "best" Pareto efficient point (of which there are a set) will be selected by the market without intervention, only that some such point will be. 1349:, and free will Arrow concluded that there is no rational way to articulate individual preferences forms together resulting in a harmonious social status of the various social societies. 1956:
The field of welfare economics is associated with two fundamental theorems. The first states that given certain assumptions, competitive markets (price equilibria with transfers, e.g.
