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).
In Fig. 13 the point x is a point of tangency which is also a point at which indifference curves are locally separated by the dashed price line; but since they are not globally separated the point is not an equilibrium according to Arrow and Debreu's definition. Fig. 14. A Pareto optimum which is not a 'competitive equilibrium'
Blue curve of Pareto efficient points, at points of tangency of indifference curves in an Edgeworth box.If the initial allocations of the two goods are at a point not on this locus, then the two people can trade to a point on the efficient locus within the lens formed by the indifference curves that they were originally on.
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 ...
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]
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]
For example, every point on the indifference curve I1 (as shown in the figure above), which represents a unique combination of good X and good Y, will give the consumer the same utility. Indifference curves have a few assumptions that explain their nature. Firstly, indifference curves are typically convex to the origin of the graph.
At this point, the slope of the isoquant, and the slope of the isocost, will be equal (see intersection of graph D). A firm has incentive to produce at the least cost combination because it is at this point, the related costs of desired production are minimised. [9] As with indifference curves, two isoquants can never cross.
