General Equilibrium

The theory of general equilibrium is placed at the top of the building neoclassical microeconomic. The overall balance depends on the results generated by the theories of "floors" below. The first level concerns the terms of the economic calculation of the consumer and that of producer. The analysis is normative in that it is to specify the behaviour to be adopted one hand the consumer to maximize his utility under budget constraint, and the other manufacturer to maximize its super-profits. It is both in terms of optimal combination of inputs, the factors of production-and in terms of optimal amount of output to provide the market. The conclusions drawn from this first level the results derived in the analysis, positive conducted on the second level the calculation of the consumer is derived demand function of a single Well. According to the different variables that determine it, especially the price of such property, that of other goods and the consumer's income, and the calculation of the producer follows the supply function individual, depending on market prices (Fullerton, 1981).

The demonstration by Arrow and Debreu at least a competitive general equilibrium is an essential contribution to modern microeconomic theory. This model is the basis on which was built the current neo-classical theory: neoclassical theorists see in this model demonstrate that prices can be a means of coordinating individual decisions. There is a vector of prices that equates supply and aggregate demand for each good in this economic activity. (Dennym, 1997).

Arrow-Debreu General Equilibrium

Arrow and Debreu have shown that the theory of general equilibrium was capable to account for price-fixing by competitive markets in an economy production, time and subject to uncertainty. But everyone agrees that the so-called "Arrow-Debreu model of general equilibrium" man particularly that of realism. We saw indeed only one time, the economic researchers make decisions binding on the present and the future. Now the future is uncertain and probably even it is far more uncertain. The peculiarity of the Arrow-Debreu model of general equilibrium is to introduce to the initial period (François, 2001).

A wide range of markets which determine the equilibrium price of all property (or contract) for all future periods and for all possible states of the world. Once the equip- Free reached, each economic agent market returns with the best possible realty cart but also the best care possible contracts for future deliveries of goods in all states of the world imaginable. Thus, returning the market, I have already bought the coat I want consumed in fifteen years if it rains in Britain. The Arrow-Debreu model seems to admit the existence of only one broad set of markets, held a once and for all. It is responsible for establishing the set of all contracts for the purchase and sale. The rest of the story is simple: from initial until the beginning of time, the agents simply to honor the contracts they established to deliver the physical commodity at the moment and in the ...
