  Edgeworth box - Wikipedia, the free encyclopedia
In economics, an Edgeworth box, named after Francis Ysidro Edgeworth, is a way of representing various distributions of resources.
The Edgeworth box is a rectangular diagram with Octavio's origin on one corner (represented by the O) and Abby's origin on the opposite corner(represented by the A).
Edgeworth's original two axis depiction was developed into the now familiar box diagram by Pareto in 1906 and was popularised in a later exposition by Bowley.

 Francis Ysidro Edgeworth - Wikipedia, the free encyclopedia
Edgeworth was a highly influential figure in the development of neo-classical economics.
He is also known for the Edgeworth conjecture which states that the core of an economy shrinks to the set of competitive equilibria as the number of agents in the economy gets large.
Edgeworth's "range of final settlements" was later resurrected by Martin Shubik (1959) as the game-theoretic concept of "the core".

Edgeworth // Brief biography Francis Ysidro Edgeworth (February 8, 1845 - February 13, 1926) was an Irish polymath who studied at Trinity College, Dublin before obtaining a scholarship to Balliol College, Oxford where he subsequently became a professor.
It is applied by economists in such topics as the indifference curve, which measures the combination of a basket of commodities that an individual or a community requests at a given level(s) of satisfaction.

 Francis Ysidro Edgeworth
Edgeworth also articulated what eventually became known as "Edgeworth's conjecture", namely that as the number of agents in an economy increase, the degree of indeterminacy is reduced.
Edgeworth also set the utilitarian foundations for highly progressive taxation, arguing that the optimal distribution of taxes should be such that "the marginal disutility incurred by each taxpayer should be the same" (Edgeworth, 1897).
Whatever his motivations, it is true Edgeworth's professional activities contributed directly to the ascendancy of the Marshallian Neoclassical hegemony and the decline of alternative approaches in Britain around the turn of the century.

The concept is applied by economists in such topics as the indifference curve, which plots the combination of commodities that an individual or a community requires to maintain a given level of satisfaction.
The concept is also used in utility functions, social welfare functions, Pareto maximization, Edgeworth boxes and contract curves.
Welfare economics is a branch of economics that uses microeconomic techniques to simultaneously determine the allocational efficiency of a macroeconomy and the income distribution consequences associated with it.

 Edgeworth's Conjecture
Edgeworth established that barter exchange yields the indeterminacy known as the core.
Edgeworth (1884) drew a rather interesting analogy between his own "limit theorem" on core convergence to equilibrium with the Central Limit Theorem of statistics.
Edgeworth's procedure in proving this was effectively the same as that followed later by Herbert E. Scarf (1962) and Gérard Debreu and H.E. Scarf (1963): namely, by the replication of the economy.

If we fit the two indifference curve graphs together into a single box (called Edgeworth's box), then we can examine how the food is distributed.
Since each point within the box corresponds with a possible distribution of food, we need to suggest a starting point.

 Edgeworth-Box - Bedeutung, Definition, Erklärung im netlexikon
Die Edgeworth-Box (nach Francis Ysidro Edgeworth) ist ein grafisches Konstrukt, das sich aus zwei Diagrammen mit Indifferenzkurven zusammensetzt.
Die Edgeworth-Box eignet sich zur Analyse der Allokation von zwei verschiedenen Gütern zwischen zwei Individuen in einer (Tausch-)Wirtschaft in der Haushaltstheorie oder auch der Aufteilung zweier Inputfaktoren auf zwei Unternehmen in der Produktionstheorie.
Die "Box" entsteht durch die Zusammenlegung von zwei binären Koordinatensystemen, welche jeweils ein Wirtschaftssubjekt repräsentieren (oder: ein Wirtschaftssubjekt und das Aggregat aller anderen Wirtschaftssubjekte).

Her first novel, Castle Rackrent (1800), dealt with Anglo-Irish country society and was the first regional novel in English.
Edgeworth was born in Black Bourton, near Oxford, daughter of Richard Lovell Edgeworth.
Much of her life was spent on her father's Irish estate at Edgeworthstown and she helped him in his writing, especially in Practical Education (1798) and the ‘Essay on Irish Bulls’ (1802).

 Valid Edgeworth Expansions for the Whittle Maximum Likelihood Estimator for Stationary Long-memory Gaussian Time Series
In this paper, we prove the validity of an Edgeworth expansion to the distribution of the Whittle maximum likelihood estimator for stationary long-memory Gaussian models with unknown parameter theta in Theta subset R^{d_{theta}}.
Lieberman, Rousseau, and Zucker (2002) (LRZ) establish a valid Edgeworth expansion for the maximum likelihood estimator for stationary long-memory Gaussian models.
The results given here improve upon those of LRZ in that the results provide an Edgeworth expansion for an asymptotically efficient estimator, as LRZ do, but the error of the expansion is shown to be o(n^{-(s-2)/2}), not o(n^{-1}), for a broad range of models.

 Walrasian Pure Exchange
We then represent Walrasian pure exchange via the "Edgeworth-Bowley box" introduced by Pareto (1906), and consequently derive a representation of equilibrium via price-consumption curves and, finally, net trade diagrams.
The "box" is formed by the corresponding axes.
This is derived from a simple Edgeworth-Bowley box, and is particularly useful when trying to analyze economies with more than two agents for which the Edgeworth-Bowley box usually does not work.
