1 Ιαν 2018 · The axiomatic and rigorous approach that characterized the formulation of general equilibrium by Arrow–Debreu has been enormously influential. It is now taken for granted that a model is not properly defined unless it has been proved to be logically consistent.
The Arrow and Debreu Model. Sometimes called the neo-Walrasian approach, A&D combine the insights of Walras-Cassel and Edgworth-Pareto. The principle idea is this: The problem is no longer conceived as that of proving that a certain set of equations has a solution.
This Arrow-Debreu model (known for two of its most prominent founders, both Nobel Laureates) is the basis of modern price theory and of a wide range of appli-cations. The text starts with elementary models: Robinson Crusoe, the Edgeworth Box, and a two-commodity two-household two-firm model.
The Arrow-Debreu Model of Competitive Equilibrium -Definition and Existence. A. Existence of General Equilibrium in a simple model. Overview: The issue of ’existence’ of general equilibrium is to demonstrate sufficient conditions on a competitive economy so that there is an array of market-clearing prices.
A general model of noncooperative trading equilibrium is described in which prices depend in a natural way on the buying and selling decisions of the traders, avoiding the classical...
This paper formalizes two economic models in Isabelle/HOL: the pure exchange economy, where the only economic actors are consumers, as well as a version of the Arrow-Debreu Model, a private ownership economy, which includes production facilities.
The class of general equilibrium models of Arrow (1964), Debreu (1959), McKenzie (1959), and others is an excellent starting point for the study of actual economies.
