consumer equilibrium

the point at which the consumer maximizes his TOTAL UTILITY or satisfaction from the spending of a limited (fixed) income. The economic ‘problem’ of the consumer is that he has only a limited amount of income to spend and therefore cannot buy all the goods and services he would like to have. Faced with this constraint, demand theory assumes that the goal of the consumer is to select that combination of goods, in line with his preferences, that will maximize his total utility or satisfaction. Total utility is maximized when the MARGINAL UTILITY of a penny's worth of good X is exactly equal to the marginal utility of a penny's worth of all the other goods purchased; or, restated, when the prices of goods are different, the marginal utilities are proportional to their respective prices. For two goods, X and Y, total utility is maximized when:

Consumer equilibrium can also be depicted graphically using INDIFFERENCE CURVE analysis. See Fig. 30 . See also REVEALED PREFERENCE THEORY,PRICE EFFECT, INCOME EFFECT, SUBSTITUTION EFFECT, ECONOMIC MAN, CONSUMER RATIONALITY, PARETO OPTIMALITY is equal to the slope of the indifference curve (the ratio of marginal utilities), so the goods’ marginal utilities are proportional to their prices.

The market stationary equilibria, at which for every t the population shares and thus also the market equilibrium price and the consumer equilibrium quantities are constant, will be called trivial if they are not characterized by the coexistence between the two groups of agents, and nontrivial otherwise.

Budget line Z enables the typical person to achieve consumer equilibrium at some point C, which represents more utility than B but less than A The effect of either type tax is to lower a person's utility from what it could be, but the excise tax lowers it more than does the income tax.
This section derives the condition for consumer equilibrium. The condition is derived through sequential use of the definitions of MRS and RP.
The present analysis differs from utility-based demand theory in having its consumer equilibrium condition in the form of a single equation:
Denoting the reservation price by [r.sup.k] for k = h, l, a consumer equilibrium is generated by (8) [Mathematical Expression Omitted] for i, j = d, f; i [is not equal to] j and [p.sub.i] > [p.sub.j].

This paper has shown that consumer equilibrium can be thought of as achieved sequentially and that the consumer chooses the amount of each good for which its MRS equals its RP.
