  2. Indifference curve - Wikipedia

    en.wikipedia.org/wiki/Indifference_curve

    Complete, such that all points on an indifference curve are ranked equally preferred and ranked either more or less preferred than every other point not on the curve. So, with (2), no two curves can intersect (otherwise non-satiation would be violated since the point(s) of intersection would have equal utility).

  3. Contract curve - Wikipedia

    en.wikipedia.org/wiki/Contract_curve

    By varying the weighting parameter b, one can trace out the entire contract curve: If b = 1 the problem is the same as the previous problem, and it identifies an efficient point at one edge of the lens formed by the indifference curves of the initial endowment; if b = 0 all the weight is on person 2's utility instead of person 1's, and so the ...

  4. Utility maximization problem - Wikipedia

    en.wikipedia.org/wiki/Utility_maximization_problem

    For a minimum function with goods that are perfect complements, the same steps cannot be taken to find the utility maximising bundle as it is a non differentiable function. Therefore, intuition must be used. The consumer will maximise their utility at the kink point in the highest indifference curve that intersects the budget line where x = y. [3]

  5. Indifference graph - Wikipedia

    en.wikipedia.org/wiki/Indifference_graph

    An indifference graph, formed from a set of points on the real line by connecting pairs of points whose distance is at most one. In graph theory, a branch of mathematics, an indifference graph is an undirected graph constructed by assigning a real number to each vertex and connecting two vertices by an edge when their numbers are within one unit of each other. [1]

  6. Edgeworth box - Wikipedia

    en.wikipedia.org/wiki/Edgeworth_box

    If the curves cross (as shown in Fig. 4) then they divide the immediate neighbourhood into four regions, one of which (shown as pale green) is preferable for both consumers; therefore a point at which indifference curves cross cannot be an equilibrium, and an equilibrium must be a point of tangency.

  7. Corner solution - Wikipedia

    en.wikipedia.org/wiki/Corner_solution

    If you do not find a tangency point within the domain then the utility maximising indifference curve for the given budget constraint will be at an intersection between either the x or y axis (depending on whether the slope of the indifference curve is strictly greater than or less than the slope of the budget constraint) - this is a corner ...

  8. Shapley–Folkman lemma - Wikipedia

    en.wikipedia.org/wiki/Shapley–Folkman_lemma

    On this set of baskets, an indifference curve is defined for each consumer; a consumer's indifference curve contains all the baskets of commodities that the consumer regards as equivalent: That is, for every pair of baskets on the same indifference curve, the consumer does not prefer one basket over another. Through each basket of commodities ...

  9. Marginal rate of substitution - Wikipedia

    en.wikipedia.org/wiki/Marginal_rate_of_substitution

    Under the standard assumption of neoclassical economics that goods and services are continuously divisible, the marginal rates of substitution will be the same regardless of the direction of exchange, and will correspond to the slope of an indifference curve (more precisely, to the slope multiplied by −1) passing through the consumption bundle in question, at that point: mathematically, it ...
