He now works for TL2 hours per day, TL1 at hourly wage rate w and L1L2 at higher wage rate w. Further, these stamps cannot be traded or transferred to the other people. This cookie is set by GDPR Cookie Consent plugin. Thus in this case rationing is actually binding on him and reduces his welfare. Thus the indifference curve I4 indicates a higher level of satisfaction than I3 which, in turn, is indicative of a higher level of satisfaction than I2 and so on. This cookie is set by GDPR Cookie Consent plugin. An indifference curve is a graphical representation of various combinations or consumption bundles of two commodities. 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. You also have the option to opt-out of these cookies. When the wage rate rises to W1 (budget constraint becomes TM1 in panel (a) of Fig. An indifference curve is a downward sloping convex line connecting the quantity of one good consumed with the amount of another good consumed. Hence the name indifference curve. This property of indifference curves follows from assumption 3, which is that the marginal rate of substitution of X for Y (MRSxy) diminishes as more and more of X is substituted for Y. It is like a contour map showing the height of the land above sea-level where instead of height, each indifference curve represents a level of satisfaction. (4) The prices of the two goods are given. (7) An indifference curve is negatively inclined sloping downward. We use cookies to personalise content and ads, to provide social media features and to analyse our traffic. It is thus clear that for an individual supplier of labour income effect and substitution effects work in opposite directions. (3) The consumer possesses complete information about the prices of the goods in the market. 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. Since the food stamps are in addition to his initial income OB1 his budget line with food stamps becomes a kinked line B1 CL2.

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. Direct taxes are those taxes whose incidence cannot be shifted to others. We will now explain the consequences if both the commodities X and Y are rationed. A customer's marginal utility is the satisfaction or benefit derived from one additional unit of product consumed. In short, the first condition of the consumer's equilibrium is that the budget or price line should be tangent to the indifference curve. The curves that are farther away from the origin represent higher levels of satisfaction as they have larger combinations of X and Y. When the indifference curve is convex to the origin, MRS diminishes as more of X is substituted for K. We therefore conclude that indifference curves are generally convex to the origin. He has earned OM1 amount of income by working TL1 hours of work. Another point which is worth mentioning in this regard is that indifference curves cannot even meet or touch each other or be tangent to each other at a point. The better substitutes the two goods are for each other, the closer the indifference curve approaches to the straight-line so that when the two goods are perfect substitutes, the indifference curve is a straight line. supply of labour in terms of hours worked) he would put in this optimal M situation. Login details for this Free course will be emailed to you. If the total satisfaction is to remain the same, the consumer must part with a diminishing number of bananas as he gets as increasing stock of oranges. Since PT amount of money is paid by the individual himself, the remaining amount TN or RM (the vertical distance between the price lines PL1 and PL2 at OA amount of food) is paid by the Government as food subsidy for the individual. This is an important feature of an indifference curve. 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. If the graph is on the curve or line, then it means that the consumer has no preference for any goods, because all the good has the same level of satisfaction or utility to the consumer. 11.18(b). Choice of other points on income-leisure line MT will show different amounts of leisure, income and work. Higher indifference curve represents larger bundles of goods i.e. 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. In this figure we measure money income on the Y-axis and leisure (reading from left to right) and labour supply (reading from right to left) on the X-axis. The ordinal utility theory or the indifference curve analysis is based on the assumptions as discussed above. A single indifference curve concerns only one level of satisfaction. 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. Now, if substitution effect had been larger than income effect, work-hours supplied would have increased as a result of rise in wage rate. The indifference curve technique has come as a handy tool in economic analysis. Income Effect and Substitution Effect of the Change in Wage Rate: Now the supply curve of labour does not always slope upward as is shown in Fig. That is, at wage rate w0he supplies TL0 amount of labour. This shows with rise in wage rate from w0 to w1 resulting in leisure becoming relatively expensive, he substitutes work (i.e. Economists have adopted the principles of. If the government is eager to raise the tax revenue and at that time the government may face the issue regarding whether it . If the Government provides the consumer lump-sum cash grant of RM instead of price subsidy on food, this will amount to increasing the money income of the consumer by RM amount. But ration limit Rx for good X is larger than his optimum or equilibrium consumption quantity of good X. "Nothing is more important than my child's safety" is a corner solution in its refusal to admit there might be trade . As noted above, combination H is not available under food stamp subsidy because food stamps cannot be used to purchase other goods. Therefore, the ration limits in this case are not actually binding since these do not any more constrain his consumption. Budget Line: Notes on Budget Line, Space, Changes and Slope. 8.6. The very important feature of the indifference curves is that they are convex to the origin and they cannot be concave to the origin. An indifference curve can neither be horizontal line nor an upward sloping curve. However, it is important to note that he . This is directly plotted against the wage rate w0 in panel (b) of Fig. 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. The second possibility of the effect of food stamp subsidy is illustrated in Fig. Ms. Bain is indifferent among combinations W, X, and Y. The less the ease with which two goods can be substituted for each other, the greater will be the fall in the marginal rate of substitution. 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. 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. Introduction of rationing limits forces him to come to point K on the lower indifference curve IC0 and consume less amounts of both the goods than he would do without the restriction of rationing. With these stamps, the recipient can buy food and only food.

CFA Institute Does Not Endorse, Promote, Or Warrant The Accuracy Or Quality Of WallStreetMojo. By clicking Accept, you consent to the use of ALL the cookies. 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. Lump sum tax, proportionate and progressive income taxes, wealth tax, death duty are the examples of direct tax. 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. It will be seen from Figure 11.1 that PE is less than RM which is the amount of money paid by the Government as subsidy. The importance of indifference curve analysis to neoclassical microeconomic consumer theory can hardly be overstated. Thus above the horizontal line B1C1 the combinations of other goods and food are not attainable when he is given the food stamps of Rs. It is worth noting that wage rate is the opportunity cost of leisure. The greater the fall in marginal rate of substitution, the greater the convexity of the indifference curve. Share Your PPT File. It will be seen from Figure 11.16 that the given income-leisure line MT is tangent to the indifference curve IC2 at point E showing choice of OL1 of leisure and OM1 of income. The loss of satisfaction to the consumer on account of the downward movement must be made up by the gain through the rightward movement. Each individual axis indicates a single type of economic goods. 2. You consent to our cookies if you continue to use our website. In the diagram, IC1 and IC2 are the two indifference curves. 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. 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. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. IC2 is a higher indifference curve than IC1. Thus, indirect tax (excise duty) causes an excess burden on the individual. it helps to compare the satisfaction of different goods/commodities and enables the consumer to attain the equilibrium. TOS4. The difference between the chosen plan of action and the next best plan is known as the opportunity cost. In other words, at point Q2 individuals level of welfare is higher than at Q1. Where the X-axis indicates one commodity (Cloth) and Y-axis refers to another good (Book). 1.). An indifferent curve is drawn from the indifference schedule of the consumer. Assumes marginal rate of substitution to diminish. It Provides a . This is the point of consumer equilibrium, where the consumer purchases OM quantity of commodity 'X' and ON quantity of commodity 'Y. Suppose that under food-subsidy programme, the needed families are entitled to purchase food at half the market price, the other half of the market price is paid by the Government as subsidy. At the extreme, when two goods cannot at all be substituted for each other, that is, when the two goods are perfect complementary goods, as for example gasoline and coolant in a car, the indifference curve will consist of two straight lines with a right angle bent which is convex to the origin as shown in Fig. It is worth noting that price subsidy on a commodity is also generally called excise subsidy. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. 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. But the two indifference curves cutting each other lead us to an absurd conclusion of A being equal to Bin terms of satisfaction. However, his preference for those combined products can be arranged in the order of preference. If the individual can work for all the 24 hours in a day, he would earn income equal to OM. With a given income of the individual and the given price of good X, the price line is PL1 which is tangent to indifference curve IC3 at point Q3 where the individual is in equilibrium position. goods other than food). All combinations give him equal satisfaction. The slope of the curve at any given point represents utility for any combination of two goods. When a curve intersects the budget limit of an individual consumer, it creates an optimal consumption bundle. Cookies help us provide, protect and improve our products and services. This is because food and other goods are here considered as normal goods whose quantity demanded increase with the increase in income. Share Your PDF File Disclaimer Copyright, Share Your Knowledge AB is tangent to indifference curve IC1 at point S at which he supplies TL2 hours for work. it slopes downward from left to right. An indifference curve is a graph that represents the different combinations of two goods that give an individual the same level of satisfaction or utility. 11.3 and Fig. Answer (1 of 3): The following points highlight the top nine advantages of indifference curve technique over marshallian utility analysis. If a consumer purchases two goods, the budget limitation can be displayed with the help of a budget line on a graph. Plagiarism Prevention 4. According to Watson, An indifference schedule is a list of combinations of two commodities the list being so arranged that a consumer is indifferent to the combinations, preferring none of any other. The following is an imaginary indifference schedule representing the various combinations of goods X and Y. The Indifference Map refers to a set of Indifference Curves that reflects an understanding and gives an entire view of a consumers choices.
