Indifference Curves: Meaning and Assumptions (With Diagram)

Sammy has gotten a raise. This is what is known as marginal decreasing replacement. If these indifference curves intersect each other, the intersection will represent same level of satisfaction, which is impossible. The ridge lines R 1 and R 2 mark the boundaries of the effective segments of the indifference curves. As we move along the indifference curve we increase the quantity of one of the goods, each time a smaller amount of the other is needed to compensate for the change, so that the slope of the curve is made each time more flat. When the man drinks 12 cup of coffee, he consumes 1 cigarette every day. To make the must select a point on that curve on the line between 1,2 , where we hire Chris for 1 hour and Sammy for 2, and 3,1 where we hire Chris for 3 hours and Sammy for 1.

Properties of Indifference Curves

The actual values of the function have no importance. Indifference Curve: Concept Properties Features Examples Examples of Indifference Curve Example No. This follows from common sense: if the market values a good more than the household, the household will sell it; if the market values a good less than the household, the household will buy it. Joining together these points gives us the demand curve for apple, which slopes down to the right. Under certain special circumstances an indifference curve may be a straight line or even concave to the origin. The curve will be a convex one if the marginal rate of substitution diminishes; the concavity will obtain if the marginal rate of substitution Rises; and the constant marginal rate of substitution will give us a straight line curve.

Indifference Curves: Assumptions and Properties

indifference curve map

An indifference map is the collection of indifference curves possessed by an individual. Assumptions of Indifference Curve Analysis: The indifference curve analysis retains some of the assumptions of the cardinal theory, rejects others and formulates its own. For most goods the marginal rate of substitution is not constant so their indifference curves are curved. Therefore, an indifference curve cannot be vertical either. There is thus no indiffer­ence curve. Let us look at figure 5.

As he moves from combination A to 6 he gives up less quantity of Y in order to have more of X. Hence, an indifference curve to the right always represents higher level of satisfaction. A Counter Example: In case of lexicographic orderings, an indifference curve does not exists in the true sense. Most economic textbooks build upon indifference curves to introduce the optimal choice of goods for any consumer, based on that consumer's income. This is so because indifference curves are assumed to be negatively sloping and convex to the origin. The bottom part of the Fig.

What is Indifference Map? definition and meaning

Non satiety Satiety means saturation. How does this impact your decision? The blue curve, however, is completely below our budget line, meaning all the points represented by that line are feasible but inefficient. N is, therefore, not a position of equili­brium. The following conclusions must be fulfilled for a consumer to be in equilibrium. Diminishing marginal rate of substitution Marginal rate of substitution may be defined as the amount of a commodity that a consumer is willing to trade off for another commodity, as long as the second commodity provides same level of utility as the first one.

Difference between “Indifference Curve” and Indifference Map”

Following the example, if we start from the first basket 5 pencils and 10 pens , to get 5 more pens this individual will need 2 pencils. . The level of satisfaction of consumer for any given combination of two commodities is same for a consumer throughout the curve. The slope of the curve becomes smaller as we move to the right. If we look closely, we see that any points between 1,3 and 2,2 are feasible as they intersect with our brown budget line. It means that as the amount X is increased by equal amounts that of Y diminish by smaller amounts.

This set of combinations can be shown geometrically with the help of a straight line is drawn in fig this line is called the budget line. Only the ranking of those values has content for the theory. Article shared by : We may now examine the implications of the axioms in the context of the properties of indifference curves. Combination at point Q contains more of both the goods X and Y than that of the combination at point S. The indifference curve I 1 is the locus of the points L, M, N, P, Q, and R, showing the combinations of the two goods X and Y between which the consumer is indifferent.

The Indifference Curve Analysis

Equivalently, , such that more of either good or both is equally preferred to no increase, is excluded. It is possible to identify two or more points on the indifference plane, which shows different combinations of good X and Y, yielding the same level of utility. As we know that all indifference curve slope downward to right or they have negative slopes. For this reason, an indifference curve always has a negative slope. To the right of X, all bundles contain more x 1; hence all points to the right of x 1, regardless of which quadrant they are in, are preferred to X.
