A market can be said to have allocative efficiency if the price of a product that the market is supplying is equal to the marginal value consumers place on it, and equals marginal cost. In other words, when every good or service is produced up to the point where one more unit provides a marginal benefit to consumers less than the marginal cost ...
Constrained Pareto efficiency is a weakening of Pareto optimality, accounting for the fact that a potential planner (e.g., the government) may not be able to improve upon a decentralized market outcome, even if that outcome is inefficient. This will occur if it is limited by the same informational or institutional constraints as are individual ...
Allocative efficiency is a state of the economy in which production is aligned with the preferences of consumers and producers; in particular, the set of outputs is chosen so as to maximize the social welfare of society. [1] This is achieved if every produced good or service has a marginal benefit equal to the marginal cost of production.
Efficiency notions: Pareto-efficiency, graph Pareto-efficiency (where Pareto-domination considers only exchanges between neighbors on a fixed graph), and group-Pareto-efficiency. An allocation X as k-group-Pareto-efficient (GPE k ) if there is no other allocation Y that is at least as good (by arithmetic mean of utilities) for all groups of ...
This is a price-vector and an allocation, such that (a) each allocated bundle is optimal to its agent given his/her income - the agent cannot purchase a better bundle with the same income, and (b) the market clears - the sum of all allocations exactly equals the initial endowment. The equilibrium allocation is provably envy free and Pareto ...
The Lange model contains principles proposed by neoclassical economists Vilfredo Pareto and Léon Walras. Lange's theory emphasizes the idea of Pareto efficiency: a situation is Pareto-efficient if there is no way to rearrange things to make any individual better off without making anyone worse off.
