Introduction to Indifference Curve and Perfect Substitutes. In India also food stamp programme has been suggested in recent years as an anti-poverty measure. That is, income is earned by sacrificing some leisure. He is in equilibrium at point E where he consumes quantity of good X which is smaller than the ration amount Rx. 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. It Provides a . It allows the consumer to buy within a given budget, i.e., within their current income. Here, of course, is a special case of general principle that, apart from considerations of etiquette and sentiments, you can make someone happier if you give him cash instead of a commodity even if the commodity is something he wants. Thus, the maximum amount of leisure time that an individual can enjoy per day equals 24 hours. In particular we are interested in knowing whether it is the ration limits or income of the consumer that is binding, that is, which forces the consumer to consume less amounts of the goods. In the curve, the quantity consumed by B2 will compensate for the increase in the amount consumed by B2. Therefore, in economics leisure is regarded as a normal commodity the enjoyment of which yields satisfaction to the individual. Effect of Rationing On Consumers Welfare: Indifference curve analysis can be used to explain under what conditions rationing of goods by the Government can act as binding or a constraint on consumers choices and further how it affects his welfare. This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. Now, suppose with the introduction of rationing, ration limit R is fixed for good X and R, for good Y. 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. 200. It follows that PE is less than RM. Under food stamp programme, some stamps or coupons are given to the eligible persons or households. One of the properties of the indifference curve is that it is strictly convex and never concave. Consumer goods are the products purchased by the buyers for consumption and not for resale. It can slope or bend backward too which implies that at a higher wage rate, the individual will supply less labour (i.e. As one moves along a straight-line indifference curve of perfect substitutes, marginal rate of substitution of one good for another remains constant. 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. Figure 11.16 displays income-leisure equilibrium of the individual. The cookie is used to store the user consent for the cookies in the category "Analytics". The degree of convexity of an indifference curve depends on the rate of fall in the marginal rate of substitution of X for Y. Effect of Subsidies to Consumers: Price Subsidy Vs. Cash Subsidy: An important application of indifference curves is to analyse with its aid the effect of subsidies to the consumers. This is a substitution effect of the rise in wage rate tends to reduce leisure and increase labour supply (i.e. Higher indifference curve represents larger bundles of goods i.e. It has, however, been empirically observed that when the wage rate is small so that the demand for more income to purchase goods and services is very strong, substitution effect is larger than the income effect so that the net effect of rise in wage rate will be to reduce leisure and increase the supply of labour. It is assumed that consumers preferences are monotonic i.e. This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. (12) The consumer is in a position to order all possible combinations of the two goods. It will be observed that binding by rationing lowers his level of welfare as he is forced to come to the point L on a lower indifference IC0 where he consumes less of good Y and more of good X than he prefers. IC is strictly Convex to origin i.e. We will further show how much K work effort (i.e. The shaded region bounded by the budget line BL and the coordinate axes represents market opportunity set from which the consumer can make a choice of the two commodities. You may also have a look at the following articles to learn more , Your email address will not be published. Until the early 20th century, economists had been unable to provide a . 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. After reading this article you will learn about: 1. The consumer behavior remains constant in the analysis. Content Guidelines 2. The cookies is used to store the user consent for the cookies in the category "Necessary". An indifference curve is a graphical representation of various combinations or consumption bundles of two commodities. 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. Hence IC2 curve gives more satisfaction. The maximum amount of time available per day for the individual is 24 hours. 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. Since all consumption bundles give an equal amount of utility, the consumer is indifferent to all combinations. Share Your PPT File.

Lump-sum tax has reduced the individuals welfare less than that by the excise duty. It makes the consumer indifferent to any of the combinations of goods shown as points on the curve. 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..

Leisure time can be used for resting, sleeping, playing, listening to music on radios and television etc. Thus, as compared to the situation prior to food-stamp subsidy, he is on higher indifference curve showing a greater level of satisfaction or welfare and consuming greater quantities of food and other goods. Necessary cookies are absolutely essential for the website to function properly. An indifference curve has a negative slope, i.e. Privacy Policy3. The farther the Indifference curve from the origin, then: 2. However, the more important and relevant case of rationing is depicted in Figure 11.8. Here, we understand that all three products resting in the indifferent curve give him the same satisfaction. These cookies ensure basic functionalities and security features of the website, anonymously. The below diagram shows an indifference map with three indifference curves. Property I. Indifference curves slope downward to the right: This property implies that an indifference curve has a negative slope. It is thus clear that for an individual supplier of labour income effect and substitution effects work in opposite directions. 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. Suppose further that price of food is Rs. With this extra cash transfer equal to RM (-PC), the budget-line will shift to the right to the position CD in Fig. Such a situation arises because a consumer consumes a large number of goods and services. Empirical research conducted in the USA however reveals that most recipients of food stamp programme represent situation depicted in Fig. 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. An indifference curve can neither be horizontal line nor an upward sloping curve. In other words, PN is the market price of OA quantity of food. The technique of indifference curves has been used not only to explain consumers behaviour and demand but also to analyse and explain several other economic problems. This is an important feature of an indifference curve. These cookies track visitors across websites and collect information to provide customized ads.

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. Consumers can rank a combination of commodities based on their satisfaction levels. 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. 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. Our mission is to provide an online platform to help students to discuss anything and everything about Economics. 11.3 the individual maximises his satisfaction at point E2 where his budget line is tangent to indifference curve IC2. The cookie is used to store the user consent for the cookies in the category "Performance". Where the X-axis indicates one commodity (Cloth) and Y-axis refers to another good (Book). The following points highlight the top nine properties of Indifference Curve. Assumptions of Indifference Curve. The degree of convexity of an indifference curve depends upon the rate of fall in the marginal rate of substitution of X for Y. Each individual axis indicates a single type of economic goods. This is because some part of the income which the individual was spending on food prior to food-stamp subsidy gets released because of the food-stamps being used for its purchase and this released income is spent on non-food items. The ordinal utility theory or the indifference curve analysis is based on the assumptions as discussed above. Content Guidelines 2. If you enjoy both pizza and pasta, for example, you might not care whether you purchase 20 pizzas and no pasta . But given the preferences of the individual between food and other goods, he is in equilibrium at the same point E2 at which his budget line B2L2 is target to the indifference curve IC2.
