In indifference curve analysis, the case of two complementary goods is generally shown by right angled indifference curves which show that two goods are used in a given fixed proportion. On the demand curve graph, the vertical axis denotes the price and the horizontal axis denotes the quantity demanded. This is because income effect in case of inferior goods is negative. Forecasting with Price Elasticity of Demand. Similarly, we can derive other points corresponding to different prices of commodity X, real income being held constant. A demand curve is graph that shows the relationship between the price of a good or service and the quantity demanded within a specified time frame. It may be noted that in deriving ordinary demand curve, money income of the consumer is held constant.

Income effect of the fall in price of good X tends to increase the quantity demanded of good Y (as also of the good X) and the substitution effect of the fall in price of X works in favour of X (that is, tends to increase its quantity demanded) and against good Y (that is, tends to reduce its quantity demanded). Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. level of satisfaction or utility) after compensating variation in income has been made. (i) Increase in Price of Substitute Goods: When price of substitute goods (say, coffee) rises, demand for the given commodity (say, tea) also rises from OQ to OQ1 at its same price of OP.

Consumer is no better off than before, since compensating variation in income having been made the quantities purchased of two complementary goods has increased due to the substitution effect alone. That is why J. R. Hicks in his Value and Capital defined them by taking three commodities, X, Y and money and in terms of the concept of marginal rate of substitution. On the other hand, if price of X falls, and consumer substitutes X for money, and as a result of this, the marginal rate of substitution of Y for money increases, consumer will increase the consumption of Y (he will substitute Y for money) so that consumers marginal rate of substitution of Y for money falls to the unchanged price ratio between money and Y. are some of the examples of complementaries.

Example of a Shift in the Demand Curve When demand remains constant regardless of price changes, it is calledinelasticity. Substitute goods are those goods which can be used in place of one another for satisfaction of a particular want, like tea and coffee.

On the ordinary demand curve D0D0, we take a point E corresponding to the tangency point of a given budget line and an indifference curve which represents a given level of real income (i.e., satisfaction). Complementary goods are those goods which are used together to satisfy a particular want. As a result, the demand curve of the given commodity shifts to the left from DD to D1D1. However, it may be noted that the above condition that ordinary demand curve is flatter than the compensated demand curve is valid in case of normal goods. On the other hand, when price rises from P0 to P2, in the absence of compensating increase in his income, his quantity demanded of the commodity will decrease to a greater extent as compared to the quantity he buys when his money income is increased together with rise in price of the commodity so as to keep his real income constant.
