TL1 is the hours worked at the wage rate w represented by the slope of the income-leisure line MT. But ration limit Rx for good X is larger than his optimum or equilibrium consumption quantity of good X. 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. This is an important feature of an indifference curve. With TM1 he reaches his old equilibrium position at point H where he supplies TL1 work-hours. Further, income is used to purchase goods, other than leisure for consumption. AB is such line obtained after reducing his money income by compensating variation. It is, important to note that income is earned by devoting some of the leisure time to do some work. TM0 as budget constraint) L0, amount of work-hours (labour) are supplied.

Pen and ink, right shoe and left shoe, automobile and petrol sauce and hamburger, type writer and typists are some examples of perfect complements. Our mission is to provide an online platform to help students to discuss anything and everything about Economics. When the consumer repeatedly substitutes or consumes one good over another, the marginal rate of substitution diminishes. This is because food and other goods are here considered as normal goods whose quantity demanded increase with the increase in income. The second possibility of the effect of food stamp subsidy is illustrated in Fig. The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". CFA Institute Does Not Endorse, Promote, Or Warrant The Accuracy Or Quality Of WallStreetMojo. For instance, if price of food is Rs. An indifference curve is a graphical representation of various combinations or consumption bundles of two commodities. Your Mobile number and Email id will not be published. 8.8. Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. IC2 is the higher indifference curve than IC1. 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. 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. The food stamp programme can affect the recipient in two ways. Thus, with the rise in wage rate above W1,labour supply decreases. Further, as will be seen from Figure 11.2, with a cash grant the individual buys less food and more of other goods relative to the situation under price subsidy with the equivalent monetary cost. Share Your PPT File. It may, however, be noted that on theoretical grounds it cannot be predicted which effect will be stronger. Before publishing your articles on this site, please read the following pages: 1. Microeconomics is a bottom-up approach where patterns from everyday life are pieced together to correlate demand and supply. Since all the combinations give the same amount of satisfaction, the consumer prefers them equally. 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. Budget Line: Notes on Budget Line, Space, Changes and Slope. Now suppose that wage rate rises to w1 with the result that income-leisure constraint line rotates to TM1. 4 Important Properties of Indifference Curve (with curve diagram) - - StuDocu. Thus, the slope of the income-leisure curve OM/OT equals the wage rate. The marginal rate of substitution (MRS) indicates if a consumer is willing to sacrifice one good for another commodity while maintaining the same level of utility. Thus, in Figure 11.5, imposition of an equivalent lump-sum or income tax, the consumer moves from the equilibrium position Q3 on indifference curve IC3 to the new position Q2 on indifference curve IC2 which represents the income effect. For example, Figure 1 presents three indifference curves that represent Lilly's preferences for the tradeoffs that she faces in her two main relaxation activities: eating doughnuts and reading paperback books. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. 8.7. 11.3. The following diagram showing an indifference map consisting of three curves: We know that a consumer is indifferent among the combinations lying on the same indifference curve. Of course, these ration limits narrow down or truncate his market opportunity set at both ends on the X and Y axes, and in this way they are potentially binding but they are not effective in restraining his consumption. This cookie is set by GDPR Cookie Consent plugin. The very important feature of the indifference curves is that they are convex to the origin and they cannot be concave to the origin. (4) The prices of the two goods are given. an indifference curve helps the consumer to determine . The straight line MT is the budget constraint, which in the present context is generally referred to as income-leisure constraint and shows the various combinations of income and leisure among which the individual will have to make a choice. 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. It Provides a . On the other hand, an indirect tax not only reduces the purchasing power or real income of the consumer causing income effect, but also produces price-induced substitution effect and thus forcing him to purchase less of the commodity on which indirect tax has been levied and buy more of the non-taxed commodity. It provides equivalent satisfaction and utility levels for the consumer. Supply curve of labour shows how an individuals work effort responds to changes in the wage rate. In Figure 11.9 with a given income and prices of the two goods X and Y the consumer is in equilibrium at E buying OM of commodity X and ON of commodity Y. 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. IC is strictly Convex to origin i.e. While each axis denotes a different form of consumer goodsConsumer GoodsConsumer goods are the products purchased by the buyers for consumption and not for resale. Some of the important problems are explained below with the help of this technique. To break up this wage effect on labour supply, we reduce his money income by compensating variation in income. In other words, an indifference curve shows the different bundles of goods that a person is indifferent between, as they all provide the same level of utility or satisfaction to the individual. Economists have adopted the principles of. 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. The utility is expressed in terms of ordinal numbers. Without this type of analysis, economists would be unable to predict certain behaviors . Suppose to begin with the wage rate is w0 and if all the available hours OT are used to do work, OM0 money income is earned. Therefore, the ration limits in this case are not actually binding since these do not any more constrain his consumption. 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. If the individual can work for all the 24 hours in a day, he would earn income equal to OM. 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. Let us consider commodities B1 and B2. Such a diagram is known as an indifference map where each indifference curve corresponds to a different indifference schedule of the consumer. The below diagram shows an indifference map with three indifference curves. Empirical research conducted in the USA however reveals that most recipients of food stamp programme represent situation depicted in Fig. Meaning of Indifference Curve: The indifference curve analysis measures utility ordinally. They may represent higher or lower satisfaction of the consumer. Similarly, if a country has food surpluses and wants to dispose them of, then the food subsidy to the needy families will be the ideal measure to increase the consumption of food-grains and thereby to dispose of the food surpluses. Thus, indirect tax (excise duty) causes an excess burden on the individual. Hence, a consumer prefers to reach the tallest line to attain a higher utility level. The indifference curve technique has come as a handy tool in economic analysis. But the two indifference curves cutting each other lead us to an absurd conclusion of A being equal to Bin terms of satisfaction. This is because cash subsidy does not limit a person that he must purchase certain amount of food and is therefore free to spend as he likes. read more, theory of exchange, etc. It allows the consumer to buy within a given budget, i.e., within their current income. It should be further noted that at point Q1 (that is, after the imposition of excise duty) the individual is purchasing ON amount of good X and has paid PM amount of money for it. An indifference curve denotes a set of different combinations of two commodities or goods, providing the same level of satisfaction to the consumer. This diagram shows an example corner solution where the optimal bundle lies on the x-intercept at point (M,0). Complements are thus those goods which are used jointly in consumption so that their consumption increases or decreases simultaneously. Whereas income effect of the rise in wage rate tends to reduce supply of labour, substitution effect tends to increase it. It is for this reason that we reject indifference curves of concave or straight-line shapes and assume that indifference curves are normally convex to the origin.
