## Indifference Curve Analysis

It has the same amount of skiing as point X, but fewer days are spent horseback riding. Combinations B and D are preferred to A; however, it is not possible to state whether B is preferred to D or D is preferred to B. Trade-offs To expand upon this definition further, the business concept of opportunity cost via trade-offs is a central building block in understanding budget constraints. The fact that her indifference curve is steeper than her budget line tells us that the rate at which she is willing to exchange the two goods differs from the rate the market asks. . Hence, no point On two difference indifference curve can be common to each; The two curves will have to be perfectly independent of each other.

## What is Ordinal Utility & the Concept of Indifference Curve?

This means, any combination of two goods on the higher curve give higher level of satisfaction to the consumer than the combination of goods on the lower curve. Significance of Indifference Curve Analysis: In indifference curve approach only ordination of preferences is needed. 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. This shows the relationship between two graphs, pointing out how the substitution effect identifies the relationship between the price of a given good and the quantity purchased by a given consumer. The following diagram will help you understand this property clearer.

## Indifference Curve Analysis: An Alternative Approach to Understanding Consumer Choice

The basic premise behind this curve is that the varying income levels as illustrated by the green income line curving upwards will determine different quantities and balanced baskets along the provided indifference curves for the two goods being compared in this graph. If A has better bargaining skill than S, he can push the latter to point R. This translates to the graph above as the consumer makes choices to maximize utility when comparing the price of different goods to a given income level, substituting cheaper goods and more expensive goods dependent upon purchasing power. A consumer would be just as happy with any combination of Good X and Good Y on the curve. But the two indifference curves cutting each other lead us to an absurd conclusion of A being equal to Bin terms of satisfaction.

This allows consumers to compare the cost per pound for different brands or different sizes. The same is true for those who buy items on credit. This is known as the marginal rate of commod­ity substitution. The consumer always tends to move to a higher indifference curve seeking for higher satisfaction. Relevant to this chapter, he consistently observed utility-maximizing behavior. It overcomes the weakness of Cardinal measurement as the satisfaction cannot be measured objectively.

Its significance is based on the presumption that one becomes better off by consumption. Thus, if the first property were violated so that the consumer wished, say, to be on the lowest attainable indifference curve he would reach equilibrium at point P in Fig. As income increases, these will increase relative to one another as a ratio. Bain clearly would not give up still more days of skiing for additional days of riding. This means that the factors that underlie consumer desire for the product remains constant and consistent, but the quantity or price alters to a new point along the established curve. Suppose the ration packages given to all prisoners contained the same amounts of both coffee and tea. Which combination will the consumer choose in order to derive maximum satisfaction utility? Significance of Indifference Curve Indifference curve is one of the most important concepts in microeconomics.

It reveals the fact that the consumer is happier if he is paid the subsidy in cash rather than in the E S form of subsidised cereals. Indifference curve cannot intersect each other Each indifference curve is a representation of particular level of satisfaction. Similarly, some individuals are willing to pay to go to the expensive theaters to see a movie when it is first released. Therefore, two indifference curves cannot intersect. Does a rich person value a dollar more or less than a poor person? The law of substitution may be stated as follows: The scarcer a good, the greater its relative substitution value; its marginal utility rises relative to the marginal utility of the good that has become abundant. The marginal utility of an item can change. Definitions of Indifference Curve Prof.

## A Critical Evaluation of the Indifference Curve Analysis

What is the Marginal Rate of Substitution for Ms. The maximum amount of one good a consumer would be willing to give up in order to obtain an additional unit of another is called the The maximum amount of one good a consumer would be willing to give up in order to obtain an additional unit of another. For any two goods X and Y, with good X on the horizontal axis and good Y on the vertical axis, Utility Maximization and the Marginal Decision Rule How does the achievement of The Utility Maximizing Solution in correspond to the marginal decision rule? Hence the Indifference curves are always convex towards the point of origin. Thus indifference curve is steeper towards the Y axis and gradual towards the X axis. The absolute value of the slope of the budget line gives the price ratio between the two goods; it is the rate at which one good exchanges for another in the market.

Rice is taken on vertical axis and wheat on the horizontal axis in Figure 12. That is to say that consumer swill pay any price to get a fixed quantity. Bain prefers all the combinations on indifference curve B to those on curve A, and she regards each of the combinations on indifference curve C as inferior to those on curves A and B. Figure 1 b shows that all combinations of goods among which the con­sumer is indifferent lie along an indifference curve. The derivation of demand is a useful tool in this pursuit, often combined with a supply curve in order to determine equilibrium prices and understand the relationship between consumer needs and what is readily available in the market. One example is the price per unit based on package size. So the supply curve of this worker is positively sloped from S to E 2.

We have assumed that she wants to spend all her money and gains no utility from holding the cash. Do you accept or reject the offer? The wealth effect differs slightly from the income effect. The degree of convexity of an indifference curve depends on the rate of fall in the marginal rate of substitution of X for Y. Learning Goal 3: Understand the relevance of ordinal approach to consumer behaviour. Such a map has been drawn in Fig. Recall that consumer surplus is the area below the demand curve but above the price.

## What is Ordinal Utility & the Concept of Indifference Curve?

As stated above, when two goods are perfect substitutes of each other, the indifference curve is a straight line on which marginal rate of substitution remains constant. If a consumer could have more of one commodity without a corresponding fail in other commodities he would have achieved a higher level of satisfaction. This is a one time offer. Four combinations of tea and coffee are listed in the table. There is no other combination that would give us greater utility given our income. Having more of good, yields a higher level of utility combination D and having less of the goods yields a lower level of utility combination E.
