11.4 . As one moves along a straight-line indifference curve of perfect substitutes, marginal rate of substitution of one good for another remains constant. It is important to note that leisure is a normal commodity which means that increase in income leads to the increase in leisure enjoyed (i.e. An indifference curve is a graphical representation of a combined products that gives similar kind of satisfaction to a consumer thereby making them indifferent.Every point on the indifference curve shows that an individual or a consumer is indifferent between the two products as it gives him the same kind of utility. Share Your PPT File. 1.). With the imposition of excise duty, the price of good X will rise. 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. Some of the advantages are: 1. Since the consumer cannot use food stamps to buy non-food items (other goods) he cannot spend more than his initial income OB1 on other goods. 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. The indifference curve analysis has also been used to explain producer's equilibrium, the problems of exchange, rationing, taxation, supply of labour, welfare economics and a host of other problems. The utility is expressed in terms of ordinal numbers. The following situations may occur: In conclusion, Jack has the same level of satisfaction and utility in both situations as a consumer. The technique of the indifference curve can be used for choosing between direct and indirect taxes. Further, he is better off than before as he is now at the higher indifference curve IC2. In order to earn income for satisfying his wants for goods and services, he will devote some of his time to do work. Hence, a consumer prefers to reach the tallest line to attain a higher utility level. It could be calculated by dividing the additional utility by the amount of additional units.read more theory, the subjective theory of value, substitution effects, income, ordinal utility, etc. This means that up to a point substitution effect is stronger than income effect so that labour supply curve slopes upward, but beyond that at higher wage rates supply curve of labour bends backward. At this new equilibrium point E2 he is purchasing Of2 quantity of food and ON2 of other goods. This cookie is set by GDPR Cookie Consent plugin. Privacy Policy3. An indifferent curve is drawn from the indifference schedule of the consumer. The budget line is tangent to indifference curve IC2 at point 'E'. At different income-leisure levels, the trade-off between leisure and income varies. The below diagram shows an indifference map with three indifference curves. Combination Q on the higher indifference curve IC2 will give a consumer more satisfaction than combination S on the lower indifference curves IC1 because the combination Q contains more of both goods X and Y than the combination S. Hence the consumer must prefer Q to S. And by transitivity assumption, he will prefer any other combination such as combination R on IC2 (all of which are indifferent with Q) to any combination on IC1 (all of which are indifferent with S) We, therefore, conclude that a higher indifference curve represents a higher level of satisfaction and combinations on it will be preferred to the combinations on a lower indifference curve. Such a diagram is known as an indifference map where each indifference curve corresponds to a different indifference schedule of the consumer. In other words, if the Government wants to raise a given amount of revenue whether it will be better to do so by levying a direct tax or an indirect tax from the view point of welfare of the individuals. But the above principle regarding the programme of subsidised food, subsidised housing etc. work- hours) slopes upward and under what circumstances it bends backward can be explained in terms of income effect and substitution effect of a change in wage rate. Combinations of two goods on the curve provide Jack with the same level of satisfaction (represented by points A, B, C, D in the image). 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. As will be seen from Figure 11.5, as a result of income effect of the indirect tax the consumer moves from point Q3 on indifference curve IC3 to point Q2 on lower indifference curve IC2 and as a result of substitution effect he is further pushed to point Q1 on still lower indifference IC1. The cookie is used to store the user consent for the cookies in the category "Performance". And this later substitution effect caused due to the price-distortion by the indirect tax further reduces his welfare. A budget line reveals all the possibilities in combinations of two goods a consumer can purchase with limited income. 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. Content Filtrations 6. It, thus, maintains the same level of consumer satisfaction in all combinations. An indifference map between income and leisure is depicted in Figure 11.14 and has all the usual properties of indifference curves. As will be seen in Fig. 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. 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. 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. 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. Figure 11.16 displays income-leisure equilibrium of the individual. In this case, therefore, B1C, will be equal to 20 kg. 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. it provides an ordinal measurement of utility. 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. So, it will be seen from Figure 11.5 that with the imposition of lump sum tax equivalent in terms of revenue raising to the excise duty, we have drawn the budget line AB which is passing through the point Q1. The loss of satisfaction to the consumer on account of the downward movement must be made up by the gain through the rightward movement. Suppose further that price of food is Rs. Since we are assuming that subsidy paid by the Government is half the market price of food, the consumer would pay half the market price. 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. 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 a substitution effect of the rise in wage rate tends to reduce leisure and increase labour supply (i.e. In the following schedule (Table 1), the consumer is indifferent whether he buys the first combination of units of 18Y+1 unit of X or the fifth combination of 4 units of Y+5 units of X or any other combination.

Share Your PDF File Our assumption regarding diminishing MRSxy and the convexity of indifference curves is based upon the observation of actual behaviour of the normal consumer. 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. These combinations provide the same level of satisfaction and utility to the consumer. Let us take the case of food subsidy which is given by the Government to help the needy families. Several kinds of subsidies are paid to the individuals these days by the Government for promoting welfare of the people. (11) Both preference and indifference are transitive. Lastly, out of the two possibilities of the effects of food-stamp subsidy and cash subsidy which is the most common result, that is, the most common outcome of the two possible cases presented in Fig. Second, wage rate is the same irrespective of the number of hours he chooses to work. Since lump-sum tax or any income tax does not alter the relative prices of goods it will not result in any substitution effect. he always prefers larger bundle as it gives him higher satisfaction.

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. 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. With the imposition of lump sum tax, the price line will shift below but will be parallel to the original price line PL1. (6) He prefers more of X to less of Y or more of Y to less of X.

Jack is satisfied with 1 unit of cloth and 8 units of books. Ration limit is potentially binding here because due to ration limit the consumer cannot buy any set of two commodities lying in the region SLRX, if he so desires though his price-income situation permits him to do so. Welcome to EconomicsDiscussion.net! The usefulness of the indifference curves: it helps to distinguish between the substitution effects and the incomes effects.

Now take point on indifference curve IC2 and point B on indifference curve IC1 vertically below A. Analytical cookies are used to understand how visitors interact with the website. The indifference curve indicates the various combinations of two goods that yield equal satisfaction to the consumer. Microeconomics is a bottom-up approach where patterns from everyday life are pieced together to correlate demand and supply. Without this type of analysis, economists would be unable to predict certain behaviors . 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. The indifference curve technique has come as a handy tool in economic analysis. 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.
