On some goods, they will spend a larger proportion of their increase in income large value of e and on other goods, they may spend a smaller proportion small value of e y.

Some Important Income Elasticity : We have seen that in the price elasticity of demand, elasticity equal to one was very important as it made the division between elastic and inelastic demands.

According to this data, bed frames will have no effect on comforter sales and headboards actually act more like a substitute and will lower your comforter sales if you discount the price. This phenomenon is especially visible for situations in which only two competitors try to monopolize the market. It also allows the firm to measure how important its complementary products are to its own products. By calculating cross-price elasticity, we can measure the responsiveness and determine if the goods are substitutes, complements, or not related to each other.

If two commodities can satisfy equally well the same need, the cross- elasticity is high, and vice versa. Also, if the cross elasticity of demand equals zero, then the two products are said to be independent, and a change in the price of one product will have no effect on the demand for the other.
