Demand is not affected by Change in Price of Unrelated Goods: Demand for a commodity is affected by change in price of only related goods (substitute goods and complementary goods). If a factor besides price or quantity changes, a new demand curve needs to be drawn. A change (increase or decrease) in the price of substitutes directly affects the demand for a given commodity. 9.4. This cookie is set by Addthis.com.

According to Edge-worth-Pareto definition Y is a complementary with X in the consumers budget if an increase in the supply of X (Y constant) raises the marginal utility of Y; Y is competitive with X (or is a substitute for X) if an increase in the supply of X (Y constant) lowers the marginal utility of Y.

This is because, as explained above, with the fall in price without compensating reduction in money income, the quantity purchased of a normal commodity will increase to a greater extent than what he buys when compensating reduction in income is made. In order to keep his real income constant, if he is compensated by increase in money income, the quantity purchased of X by him will not decline as much as in the absence of compensating variation in income. The concept of consumer surplus is based on the marginal valuation of the units of a commodity and represents the excess of the sum of marginal valuations of the units of commodity purchased over the total price he pays for them.

Let us understand this through Fig. Therefore, the cross elasticity of demand is, If the price of margarine increases by 10%, demand for butter may rise 2%. 9.5 for a normal commodity, ordinary demand curve is flatter than compensated demand curve. Factors that can shift the demand curve for goods and services, causing a different quantity to be demanded at any given price, include changes in tastes, population, income, prices of substitute or complement goods, and expectations about future conditions and prices.

Similarly, due to unfavorable changes in non-price factors, the demand for the commodity has fallen from Q to Q 1 amount. By joining points such as E and S we get the compensated demand curve which includes the influence of substitution effect only, real income remaining the same or, in other words, compensated demand curve corresponds to the different equilibrium points achieved at different prices of the good X on the same indifference curve representing a given level of real income (i.e. But opting out of some of these cookies may affect your browsing experience.

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. The distinction between complementary and competitive goods will differ according to the arbitrary measure of utility which is adopted.

Elasticitymeasures how demand shifts when economic factors change. (i) Increase in Price of Complementary Goods: When price of complementary goods (say, sugar) rises, demand for the given commodity (say, tea) falls from OQ to OQ1 at the same price of OP. For example, there will be no change in the demand for tea with a change in the price of Pen. Giffen Goods Demand Curve & Examples | What is a Giffen Good? Take two goods X and Y. When this income effect for Y is stronger than substitution effect, then the quantity demanded of Y increases as a result of the fall in price of X, even though the two may be substitute goods.
