In a two good case, we can think of quantities of good X on the horizontal axis and quantities of good Y on the vertical axis. Provided by: Marginal Revolution University. The consumer is at the minimum point of satisfaction at R on the concave I 1 curve in Fig. The consumer will purchase 3 kg. It means the rate of substitution between the good X and good Y is 1:2.
Thus, Indifference curve analysis seeks to remedy this shortcoming of utility analysis. Thus for equilibrium to be stable at any point on an indifference curve, the marginal rate of substitution between any two goods must be diminishing and be equal to their price ratio i. Thus, while indifference curves have the same general shape—they slope down, and the slope is steeper on the left and flatter on the right—the specific shape of indifference curves can be different for every person. Its clear from the explanation of the first condition. In other words, how the change in the wage rate will affect the choice between leisure time and work time.
Description: Graphically, the indifference curve is drawn as a downward sloping convex to the origin. By trading, both British and French prisoners can move to higher indifference curves. The horizontal intercept is found by dividing B by the price of horseback riding, the good on the horizontal axis P H. D shifts leftward and becomes steeper. However, consumption of one good only by a consumer which the concavity of indifference curves leads us to believe is quite unrealistic.
The choice of F with five books and 100 doughnuts is highly desirable, since it is on the highest indifference curve Uh of those shown in the diagram. Thus, both the conditions need to be fulfilled for a consumer to be in equilibrium. Since the price of Apple has not changed, the consumer can purchase at the extreme 6 kg. When the consumer increased the consumption of commodity X to X2, the amount of commodity Y fell to Y2. Now, he wants to spend the entire money on two commodities X and Y.
This means that the consumer always tries to maximize his satisfaction with limited resources. Point Z, with 3 days of skiing and 4 days of horseback riding, provides more of both activities than point X; Z therefore yields a higher level of utility. Indifference curves always slope downwards from left to right. In general, any combination of two goods that lies below and to the left of an indifference curve for those goods yields less utility than any combination on the indifference curve. This is shown in figure 5.

Now, as seen above, the concavity of indifference curves for a consumer implies that the consumer spends his entire income on a commodity and therefore buys only one commodity. A further increase in income causes a further outward shift in the price line to L 2M 2. If his income increases, the price line shifts outward and becomes L 1M 1. The answer, of course, is that the definition of slope has not changed.
When she was at point S, she was willing to give up 2 days of skiing to get an extra day of horseback riding. Similarly, she prefers X to U. Each successive curve further from the original curve indicates a higher level of total satisfaction. Given the information we need, there are two condition of equilibrium. The consumer has to reach the highest possible scale of reference. This is the main theme of the theory of consumer behavior.
The scale of preferences implies that a consumer can conveniently arrange the various combinations of two or more goods available to him in order of his preferences. Points S and R also lie on the budget line. It is the slope of the budget line. She would also receive the same utility from any of the unlabeled intermediate points along this indifference curve. In terms of Marshallian or utility analysis. The above diagram shows the U indifference curve showing bundles of goods A and B.
Additionally, per the publisher's request, their name has been removed in some passages. It tries to solve how does a consumer reach the equilibrium point without measuring the utility in Cardinal numbers. Suppose a college student, Janet Bain, enjoys skiing and horseback riding. The law of diminishing marginal utility states that: A. Her move along her budget line from point S to point D suggests a very important principle.
The recession had an impact on total health care spending in 2009. For example, points A and B sit on the same indifference curve Um, which means that they provide Lilly with the same level of utility. It is easy to go awry on the issue of the slope of the budget line: It is the negative of the price of the good on the horizontal axis divided by the price of the good on the vertical axis. And, thus the curve is sloping downward from left to right. An indifference curve neither touches horizontal Axis nor vertical axis. In simple words, a consumer is said to be in equilibrium when he is getting maximum satisfaction out of his limited income. We can draw an indifference curve through any combination of two goods.
