In its analysis, core principles of microeconomics are involved. If indifference curves were concave or straight lines, the consumer would succumb to monomania, that is, he would buy and consume only one good. If the individual wants to buy more food-grains than B1C, then he will spend some part of his initial income to purchase additional food. 11.20. If the income effect is stronger than the substitution effect, the net combined effect of rise in wage rate will be to reduce labour supply. The excise duty, sales tax are the examples of indirect tax. read more, theory of exchange, etc. Assumptions of Indifference Curve. If now the Government introduces a rationing for commodity X and fixes a ration of X equal to ORx (At point Rx we have shown a vertical line showing the constraint or ration limit imposed by the rationing fixed at ORx). This supply of labour is directly shown against wage rate w0 in panel (b) of Figure 11.18. Higher indifference curve represents larger bundles of goods i.e. With equivalent food stamp subsidy of B1C the individual has to choose a point which must be on the kinked budget line B1CL2. (10) The consumer arranges the two goods in a scale of preference which means that he has both preference and indifference for the goods. In Figure 6, consider the indifference curves I 1 and I 2 and combination N and A respectively on them. An indifference curve can neither be horizontal line nor an upward sloping curve. The marginal rate of substitution shows the consumers preference for one good over another while maintaining the same level of utility. The indifference curve analysis work on a simple graph having two-dimensional. On the other hand, in case of good, case of good X in Figure 11.10 the ration limit Rx does not seem to be effective, though it is potentially binding as it truncates his market opportunity set. That is, at wage rate w0he supplies TL0 amount of labour. For instance, a child might be indifferent while having a toy, two comic book, four toy trucks and a single comic book. You can calculate it by, These cookies ensure basic functionalities and security features of the website, anonymously. With the imposition of a lump-sum tax (or any other income tax), a certain income is taken away from the consumer and he is pushed to the lower indifference curve (or a lower level of welfare) but he is free to spend the income he is left with as he likes without forcing him to substitute one commodity for another due to any change in relative price. Thus, the maximum amount of leisure time that an individual can enjoy per day equals 24 hours. This must be so if the level of satisfaction is to remain the same on an indifference curve. In fact, it would always be so whatever the subsidy and whatever the preferences of consumers so long as only the indifference curves remain convex and smooth. Nine most important properties of indifference curves are as follows: (1) A higher indifference curves to the right of another represents a higher level of satisfaction and preferable combination of the two goods. Here, we understand that all three products resting in the indifferent curve give him the same satisfaction. These cookies will be stored in your browser only with your consent. 1. This means for most of the recipients, food stamp programme has the same effect as a cash subsidy. An indifference curve is a curve that represents all the combinations of goods that give the same satisfaction to the consumer. If the individual can work for all the 24 hours in a day, he would earn income equal to OM. Since A is on a higher . If the higher overtime wage rate w represented by the steeper line EK is fixed, the individual is in equilibrium at point H on indifference curve IC2 where he chooses to have OL2 leisure time and OM2 amount of income. This property follows from assumption I. Indifference curve being downward sloping means that when the amount of one good in the combination is increased, the amount of the other good is reduced. Second, wage rate is the same irrespective of the number of hours he chooses to work. Thus, in this case, rationing is actually binding for the consumer and reduces his welfare. MRSxy is always diminishing. But there are some budget constraints due to the low income of the consumer. The cookie is used to store the user consent for the cookies in the category "Performance". Now, consider Figure 11.10 where it will be seen that ration limit Ry is smaller than consumers optimum consumption of Y as indicated by combination E of the two goods on the budget line BL which has been drawn with his given income and prices of two goods. With the further increase in wage rate to w2, the income-leisure constraint rotates to TM2 and the individual is in equilibrium when he supplies L2 work-hours which are smaller than L1. Income OM equals OT multiplied by the hourly wage rate (OM = OT.w) where w represents the wage rate. And this indifference in prices defines the opportunity costs. TOS 7. Thus, if instead of the food stamps the individual is given equivalent cash income of B1B2 (Note that with given market price of food, cash income of B1B2 can buy B1C quantity of food and thus the two are equivalent), the budget line will shift from L2 to B2 L2. Property II: Indifference curves are convex to the origin: Another important property of indifference curves is that they are usually convex to the origin. This implies that in case of lump-sum cash subsidy, the consumer will be better off and consume less food relative to the equilibrium position under price subsidy on food. Thus, his preferences are such that rationing is not actually binding for him. An indifference curve has a negative slope, i.e. The consumer is rational to maximize the satisfaction and makes a transitive or consistent choice. The Indifference Map refers to a set of Indifference Curves that reflects an understanding and gives an entire view of a consumers choices. If the purpose is to increase the consumption of food and therefore provide adequate diet to the people, then food stamp subsidy is better than cash subsidy as under the former, the individual is constrained to buy at least a given quantity of food. But a glance at Fig.8.5 will show that this is absurd conclusion since combination A contains more of good Y than combination B, while the amount of good X is the same in both the combinations. It allows the consumer to buy within a given budget, i.e., within their current income. Though the consumer can buy the ration amount, that is, ration limit is attainable but he is not willing to consume good X as much as the ration limit permits him. It will be seen from Fig. Meaning of Indifference Curve: The indifference curve analysis measures utility ordinally. Now, we can bring together the indifference map showing ranking of preferences of the individual between income and leisure, and the income-leisure line to show the actual choice of leisure and income by the individual in his equilibrium position. This increases the consumption of non-food items also. 11.3 where along the X-axis we measure quantity of food and along the F-axis we measure money which represents all other goods, (i.e. At the old price (before the excise duty was imposed), he could purchase ON quantity of good X for PT amount of money. Consumer goods companies and the industry offer a vast range of products that heavily contribute to the global economy.read more, the curve features unique combinations or consumption bundles for any two commodities in points. Ms. Bain is indifferent among combinations W, X, and Y. IC2 is a higher indifference curve than IC1. Likewise, when the wage rate rises to w2 (w2, = OM2/ OT), income-leisure line shifts to TM2 the individual chooses to have leisure time OL2 and supplies TL1 work-hours. supply of labour in terms of hours worked) he would put in this optimal M situation. Now, with TM1 as new income-leisure constraint line, the individual is in equilibrium at point H at which he supplies TL1 work-hours of labour which are less than TL0. Your email address will not be published. It shows the consumers preference for one good over another only if it is equally satisfying. Now, if instead of providing price subsidy on food, the Government gives lump-sum cash grant to the consumer equivalent to the cost of price subsidy on food, what will be its impact on the individuals welfare and consumption of food by him. The following points highlight the top nine properties of Indifference Curve. 2. An indifference curve is a downward sloping convex line connecting the quantity of one good consumed with the amount of another good consumed. However, the more important and relevant case of rationing is depicted in Figure 11.8. She could also get the same level of utility at point Y, skiing just 1 day and spending 5 days horseback riding. It's essentially the cost of the next best alternative that has been forgiven.read more play a crucial role in the curve analysis. Since at the given market price of food, he can buy ,C amount of food with the food stamps of Rs. When it occurs, it is known as the marginal rate of substitution (MRS). Before publishing your articles on this site, please read the following pages: 1. 4 Important Properties of Indifference Curve (with curve diagram) - - StuDocu. Until the early 20th century, economists had been unable to provide a . Share Your PPT File. Consumers would prefer to move in the direction indicated by the arrow in the figure. An indifference curve reveals many combinations of two goods a consumer prefers to consume. With price line PL2 the individual is in equilibrium at point R on the indifference curve IC at which he is purchasing OA quantity of food. Since the consumer gets an equal preference for all bundles of goods, they are indifferent about any two combinations on the curve. Plagiarism Prevention 4. Before publishing your Articles on this site, please read the following pages: 1. Jack has 1 unit of cloth and 8 units of the book. With the imposition of excise duty, the price of good X will rise. Before the receipt of food stamps the individual is in equilibrium at point E1 on indifference curve IC1 and is consuming OF1 quantity of food and ON1 quantity of other goods per week. 1. Therefore, given that the consumer is free to spend money as he likes, with cash grant his new equilibrium position must be to the left of point R on the budget line CD where it will be tangent to the higher indifference curve than IC2. First, he is free to work as many hours per day as he likes. Indifference curve analysis can be used to explain an individuals choice between income and leisure and to show why a higher overtime wage rate must be paid if more hours of work are to be obtained from the workers. This cookie is set by GDPR Cookie Consent plugin. The imposition of a lump-sum tax (or any income tax) does not affect the prices of goods because it is not levied on any saleable goods. In Fig. 8.8 two perfect complements are consumed in the ratio, 3X: 27. They may represent higher or lower satisfaction of the consumer. Authorized users may be able to access the full text articles at this site. Let us suppose that the individual has OP money income. MRS between income and leisure equals the wage rate (w) that is, the market exchange rate between the two. 11.19. In this case with cash subsidy the individual spends more than his initial income OB1 on other goods. You consent to our cookies if you continue to use our website. Now, suppose that instead of excise duty, Government levies a direct tax of the type of lump-sum tax on the individual when the individual is initially at point Q3 on indifference curve IC3. The basic reason for this is that whereas both the lump-sum tax (or any other general income tax) and an indirect tax reduce consumers income and produce income effect, the indirect tax in addition to the income effect, also raises the relative price of the good on which it is levied and therefore causes substitution effect. When the consumer repeatedly substitutes or consumes one good over another, the marginal rate of substitution diminishes. Here we discuss the properties of the indifference curve and how to analyze it, along with examples and assumptions. The preference-maximising point A on indifference curve I 1 shows that . Content Filtrations 6. Prohibited Content 3. But the two indifference curves cutting each other lead us to an absurd conclusion of A being equal to Bin terms of satisfaction. This cookie is set by GDPR Cookie Consent plugin. Amount of labour L1 is directly plotted against higher wage rate w, in panel (b) of Fig. The indifference curve I1 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. It provides equivalent satisfaction and utility levels for the consumer. These cookies ensure basic functionalities and security features of the website, anonymously. Hence, relief payments in cash are preferable to a food subsidy because they are economically more efficient, giving the relief receipts either a greater gain at the same cost to the Government or the same gain at a lower cost.. In other words, the combinations which lie on a higher indifference curve will be preferred to the combinations which lie on a lower indifference curve. This is depicted in Figure 11.17 where at the equilibrium point E a steeper leisure-income line EK than MT has been drawn. cannot always be validly applied to the Government subsidy programme since the above principle is based upon the subjective benefits to the individuals which is not always the correct criteria to judge the desirability of Government subsidy programme. With the budget line BL and the rationed quantity Rx he will be at point E which lies at lower indifference curve IC0. As one moves along a straight-line indifference curve of perfect substitutes, marginal rate of substitution of one good for another remains constant. It means that the price ratio of commodity-1 and commodity-2 should be equal to the marginal rate of substitution of commodity-1 for commodity-2. Therefore, this can be interpreted to be the case of a poor family whose optimum consumption basket of the two goods is small because of its low income and therefore remains unaffected if ration limits are set at higher levels. However, the final result of the two types of subsidies depends on the value of food stamps relative to preferences and incomes of the individuals whom subsidies are granted. Each indifference curve represents various alternative combinations of income and leisure which provides equal level of satisfaction to the individual and the farther away an indifference curve is from the origin, the higher the level of satisfaction it represents for the individual. For example, Dalda and Rath Vanaspati, two different brands of cold drink such as Pepsi Cola and Coca Cola are generally considered to be perfect substitutes of each other. He is also satisfied with 2 units of cloth and 4 units of books. Food Stamp Programme: In-kind Food Subsidy: Food stamp programme is a type of food subsidy to provide poor people with adequate quantity of food. The indifference curve shows that she could obtain the same level of utility by moving to point W, skiing for 7 days and going horseback riding for 1 day. An important application of indifference curves is to judge the welfare effects of direct and indirect taxes on the individuals. all of which provide satisfaction to the individual. With the budget line B1CL2 with food stamp subsidy of B1C, the best that the individual can do is to choose the corner point C of budget line B1CL2 which lies on the highest possible indifference curve IC2 which passes through the point C. Therefore, from the point of individual welfare we reach our earlier conclusion that cash subsidy is superior to in-kind subsidy represented by food stamps programme. Therefore, RM is also greater than PE. Here is an example to understand the indifference curve better. 11.3. Under what conditions supply curve of labour (i.e. Each individual axis indicates a single type of economic goods. It provides equivalent satisfaction and utility levels for the consumer. Third important property of indifference curves is that they cannot intersect each other In other words only one indifference curve will pass through a point in the indifference map 1 his property can be easily proved by first making the two indifference curves cut each other and then showing the absurdity or self-contradictory result it leads to. Such a diagram is known as an indifference map where each indifference curve corresponds to a different indifference schedule of the consumer. The cookie is used to store the user consent for the cookies in the category "Other. It is a form of in-kind food subsidy in contrast to the subsidy provided in the form of cash income, often called cash subsidy. However, it is important to note that he . Since the food stamps are in addition to his initial income OB1 his budget line with food stamps becomes a kinked line B1 CL2.

Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. Therefore, we can draw indifference curves between income and leisure both of which give satisfaction to the individual. It makes the consumer indifferent to any of the combinations of goods shown as points on the curve. If instead of giving RM as price subsidy on food, Government pays the individual cash money equal to PE, the individual will reach the same level of welfare as he does with RM subsidy. Assumes marginal rate of substitution to diminish. The indifference curve slopes down from left to right on the graph. goods other than food). If the amount substituted is imperfect, the marginal rate of substitutionMarginal Rate Of SubstitutionThe marginal rate of substitution (MRS) is the rate at which some units of an item can be replaced by another while providing the same level of satisfaction to the consumer.read more will be constant. Now, the important question is why an indirect tax (an excise duty or a sales tax on a commodity) causes excess burden on the consumer in terms of loss of welfare or satisfaction. The derivation of supply curve of labour is depicted in 11.18. If combination A is equal to combination C in terms of satisfaction, and combination B is equal to combination C, it follows that the combination A will be equivalent to B in terms of satisfaction. Report a Violation, The Supply Curve of Labour (Explained With Diagram), The Uses or Application of Indifference Curve Analysis | Economics, Relationship between Price Consumption Curve and Price Elasticity of Demand. (7) An indifference curve is negatively inclined sloping downward. The indifference curve technique has come as a handy tool in economic analysis. A glance at panel (b) of Figure 11.18 will reveal that supply curve of labour is upward sloping indicating positive response of the individual to the rise in wage rate. Economists have adopted the principles of. Property IV: A higher indifference curve represents a higher level of satisfaction than a lower indifference curve: The last property of indifference curve is that a higher indifference curve will represent a higher level of satisfaction than a lower indifference curve. That is why at point K in Fig. An indifference curve is the locus of all those combinations of two goods that yields the same level of utility (satisfaction) to the consumer so that the consumer is indifferent to purchase the particular combination s/he selects.
