Example: Consider 2 goods: Apples A and Bananas B. All these indifference curves represent different levels of satisfaction. Indifference Curves for an Investor Note that each of the curves C1, C2, and C3 represents different levels of utility for the investor. As a result, he is willing to give up less and less of bananas for each apple. Obviously, if I go all over here, 20 pounds of fruit and.

However, the theory assumes that a consumer can express utility in terms of rank. As he moves from combination A to B he gives up less quantity of Y in order to have more of X. There are instances where the slope is positive because one of theoptions i … nvolved is undesirable. Indifference Curve can never intersect each other: 5. Similarly, rate of decrease in consumption of coffee has gradually decreased even with constant increase in consumption of cigarette. Point C, however lies on both the curves.

This property of the Indifference Curve is derived from the Law of Diminishing Marginal Rate of Substitution. The problem with this violating these assumptions is that they are the basis of utility or profit maximization. Now, can you tell which of these indifference curves give higher satisfaction? The budget constraint means that the assets of a consumer are bounded by their income. Therefore, the idea of utility as a measure of happiness was abandoned and the theory of consumer behavior was reformulated according to its preferences. It's essentially saying, exactly at that point, how are you willing to trade off bars for fruit.

If it not like that, it should be either parallel to X axis or vertical or it should be an upward sloping curve as shown in the Figure 1. The indifference curve is plotted simply by asking an individual what combination of goods he prefers, for example: 10 hamburgers and 5 films; 15 burgers and 3 movies, 20 hamburgers and 2 movies, or 5 hamburgers and 7 movies. Once again, the slope is the change in the vertical axis, over the change in the horizontal axis. Thus an indifference curve cannot be a straight line. This tool is known as the indifference curves, providing different combinations of goods that provide the same level of utility or satisfaction to an individual. Therefore it is said that we can draw infinite indifference curves forming what is known as a map of indifference curves.

The last assumption is that an individual will always prefer more goods than less of a good. The Indifference Curve Analysis Within the theory of consumer choice that investigates the behavior of an economic agent as a consumer of goods and services, there is an extremely useful tool to facilitate the analysis of the consequences of price variations. This will be 15, 5. Because of this relationship, the indifference curve is bowed inward i. The whole area down here is obviously we've not preferred to anything on the curve.

The two curves I 1and I 2 shown in figure 11 are not parallel to each other. Like we've mentioned before, we're focusing on 2 goods, because if we did 3 goods we would have to do it in 3 dimensions and 4 goods would get very abstract. Also, all the points on x have the same utility, but that number is different from x. Check out the illustration below to see this. So the consumer starts valuing y more in relative terms. Simply, an indifference curve is a graphical representation of indifference schedule.

Each point on an indifference curve indicates that a consumer is indifferent between the two and all points give him the same utility. It happens because if the consumer decides to have more units of one good say apples , he will have to reduce the number of units of another good say bananas , so that total utility remains the same. This is born out of our assumption that the consumer is considering different combinations of two commodities. Indifference curves do not intersect, because different combinations of products give varying levels of satisfaction, especially when the amount of the same product is different in each curve. The marginal significance of x in terms of y is shown by the angle which the tangent makes on the X axis. As one moves along a straight-line indifference curve of perfect substitutes, marginal rate of substitution of one good for another remains constant. The higher the indifference curves are, the larger the quantities of both goods.

The following diagram will help you understand this property clearer. They Slope Negatively or Slope Downwards from the Left to the Right: This is an important feature of Indifference Curve. If a fall in the price of product A results in increased purchase of A and B, the two products are complements. And, diminishing marginal rate of substitution states that the rate by which a person substitutes X for Y diminishes more and more with each successive substitution of X for Y. To understand why this is the case, we can look at what would happen if they did intersect. One assumption is the notion of completele … ss.

The marginal do not rate of substitution increases nor does it remain constant. Thus, utility at point Q is greater than utility at point S, i. Similarly, the utility is the same at S3 and S4. This is so because Indifference Curves are assumed to be negatively sloping and convex to the origin. So, he cannot be indifferent to the combinations. As you consume mor … e of X and less of Y, X becomes less valuable in units of Y 3. He cannot therefore indifferent between P and Q.

Only a convex indifference curve can mean a diminishing marginal rate of substitution of X for K If indifference curve was concave to the origin it would imply that the marginal rate of substitution of X for y increased as more and more of X was substituted, for Y. Although, they are Falling and Negatively Inclined to the Right: Yet the rate of the fall will not be the same for all Indifference Curves. On the other hand, the slope of the indifference curve measures the number of pens that the individual is willing to give up to get another pencil. But the slope of this budget constraint measures the speed at which that consumer can compensate one good for another, and is given by the relative prices of both goods. Two commodities: It is assumed that the consumer has a fixed amount of money, whole of which is to be spent on the two goods, given constant prices of both the goods. Those are the only 2 things that we consume.
