It must be noted that a demand curve shows the relationship between the quantity demanded of a given commodity and its price. Likewise, in case of an inferior commodity use of ordinary demand curve rather than compensated demand curve leads to the overestimation of the loss of consumer surplus associated with a rise in price of a commodity. So, for example, let's take a bus ticket and we're thinking about a bus to get you a trip but you could also take a train, right?

According to this total price-effect approach, if the price of a good X falls and as a result the quantity demanded of good X increases, the quantity demanded of good Y decreases, then Y is a substitute for X. In case of inferior goods, the opposite is the case and for them ordinary demand curve is steeper than the compensated demand curve. When demand remains constant regardless of price changes, it is calledinelasticity. Y is complementary with X if the marginal rate of substitution of Y for money is increased when X is substituted for money in such a way as to leave the consumer no better off than before.

If price of Coke increases, demand for Pepsi should increase because many Coke consumers will switch over to Pepsi.

Typically, as the price rises, the demand falls; as a result, the curve slopes down from left to right. Now, the pertinent question is what degree of curvature marks the dividing line between substitutes and complementary goods. The demand curve for a substitute product is shifted to the right when the price of the other product increases. Now if there's a decrease in the price of a substitute, let's say the train tickets actually became cheaper then that's going to decrease demand for the other good in this case a decreased demand for a bus ticket. The distinction between complementary and competitive goods will differ according to the arbitrary measure of utility which is adopted. Which Factors Are Important in Determining the Demand Elasticity of a Good? It shows the quantity of a good demanded by all individuals at varying price points. 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 illustrate with the help of a diagram how much error is introduced in the estimate of consumer surplus by using ordinary demand curve rather than compensated demand curve.
