## Indifference Curve Analysis At point A, Lilly has few books and many doughnuts. Quentin also has an income effect motivation. Higher indifference curves represent a greater level of utility than lower ones. What is the Marginal Rate of Substitution for Ms. Indifference Curves are convex i. If the latter is the case, then as a consumer decreases consumption of one good in successive units, successively larger doses of the are required to keep satisfaction unchanged. All this means that the two perfect complements are used in a certain fixed ratio and cannot be substituted for each other In Fig.

## Why does Demand Curve Slopes Downward? They are only based on the assumptions that when people have less of one good they need more of another good to make up for it, if they are keeping the same level of utility, and that as people have more of a good, the marginal utility they receive from additional units of that good will diminish. If the indifference curve is horizontal to X axis, the various points on the curve A,B,C,D denoting various combinations of x commodity and y commodity may not have equal significance. And, thus the curve is sloping downward from left to right. But as a special case it will touch the Y axis at point A if the combination is between Money and Commodity as shown in the Figure 4. A decrease in the real exchange rate has the effect of increasing net exports because domestic goods and services are relatively cheaper. In the figure 7, the indifference curve is concave to the origin. A low interest rate increases the demand for investment as the cost of investment falls with the interest rate.

## Why do indifference curves slope downward? The first reason for the downward slope of the aggregate demand curve is Pigou's wealth effect. For example, consider the preferences of Manuel and Natasha in a and b. So it is better to discuss the reasons behind the law of demand or the economics of law of demand in order to understand the question under discussion. The law of demand is based on the law of diminishing marginal utility. Suppose two indifferent curves cut each other at point K as shown in Figure 3. Behavior in the case of intersecting indifference curves would be inconsistent and irrational.

## Indifference curve With this information we can draw the demand curve, as is done in the lower portion of Fig. The Marginal Rate of Substitution is the rate at which the consumer must sacrifice units of one commodity to obtain one more unit of another commodity. Does a change in income have both an income effect and a substitution effect? This has been done so in Fig 8. In the Figure 6, the tangent at point A makes a bigger angle on the X axis than the tangent at point B which makes a smaller angle. In this case if bundles b and c provide the same level of satisfaction then bundle e which represents an arithmetic average of the former, i. Tangency points between the various budget lines and indifference curves, which when joined together by a line constitute the price consumption curve shows the amounts of good X purchased or demanded at various prices. These curves, known as indifference curves represent combinations of the two goods that provide equal levels of satisfaction.

## When is indifference curve upward sloping? The downward slope of the indifference curve means that Lilly must trade off less of one good to get more of the other, while holding utility constant. The New Palgrave: A Dictionary of Economics. Equivalently, , such that more of either good or both is equally preferred to no increase, is excluded. That is, a high price level means that it takes a relatively large amount of currency to make purchases. There are infinitely many indifference curves: one passes through each combination. This case would be drawn on the graph so that the point of tangency between the new budget constraint and the relevant indifference curve occurred below point B and to the right.

## Indifference Curve Flashcards If the quantity of one goods is reduced, then you must have more of the other good to compensate for the loss. Indifference curves have a roughly similar shape in two ways: 1 they are downward sloping from left to right; 2 they are convex with respect to the origin. So, he cannot be indifferent to the combinations. You know that the higher price will push the decision-maker down to a lower level of utility, represented by a lower indifference curve. It violets the fundamental feature of consumer behaviour.

## Why do indifference curves slope downward? The substitution effect is illustrated by the movement along the original indifference curve as prices change but the level of utility holds constant, from A to C. In the upward sloping curve too, the different points on the curve differ in significance because as he moves from point A to B, he gets more of x and more of y commodities. When the domestic interest rate is low relative to interest rates available in foreign countries, domestic investors tend to invest in foreign countries where return on investments is higher. Now, the important question is why the demand curve slopes downward, or in other words why the law of demand describing the inverse price-demand relationship is valid. Therefore consumers are willing to give up more of this good in order to get another good of which they have little. Learning Goal 2: Describe the properties of Indifference Curve. .

## Indifference Curve Flashcards This is an important feature of an indifference curve. The marginal rate of substitution between perfect substitutes is likewise constant. An indifference curve on the right is preferred than the indifference curve on the left. Yet another person, whose substitution effect on leisure outweighed the income effect, might react to a higher wage by making a choice like F, where the response to higher wages is to work more hours and earn much more income. We can explain this with marginal utility analysis and also with the indifference curve analysis. However, they can, and do, identify what choices would give them more, or less, or the same amount of satisfaction.

## What are the Properties of Indifference Curve? Business Jargons 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. In a way it contributes to the Welfare economics. Thus with the fall in price from P 1 to P 2 the quantity demanded of the good falls. By setting aside the assumption of putting a numerical valuation on utility—an assumption that many students and economists find uncomfortably unrealistic—the indifference curve framework helps to clarify the logic of the underlying model. To represent these different preferences, you could easily draw the indifference curve Uh to be tangent to the new budget constraint at D or F, rather than at B. It follows that the combination F will be equivalent to E in terms of satisfaction.

## How to derive Individual’s Demand Curve from indifference Curve Analysis? (with diagram) The elbows of the curves are. Hence the consumer must prefer Q to S. These are Pigou's wealth effect, Keynes's interest-rate effect, and Mundell-Fleming's exchange-rate effect. We have seen already that demand curves price Demand slope downwards from left to right. As a result of this substitution effect, the quantity demanded of the commodity, whose price has fallen, rises. Each succeeding combination is better than the previous one.
