Cross Elasticity of Demand
The cross elasticity of demand is an economic concept that measures the responsiveness in the quantity demanded of one good when the price for another good changes.
Also called cross-price elasticity of demand, this measurement is calculated by taking the percentage change in the quantity demanded of one good and dividing it by the percentage change in the price of the other good. In economics, the cross elasticity of demand refers to how sensitive the demand for a product is to changes in price of another product.
The cross elasticity of demand for substitute goods is always positive because the demand for one good increases when the price for the substitute good increases.
For example, if the price of coffee increases, the quantity demanded for tea a substitute beverage increases as consumers switch to a less expensive yet substitutable alternative. This is reflected in the cross elasticity of demand formula, as both the numerator percentage change in the demand of tea and denominator the price of coffee show positive increases. Items with a coefficient of 0 are unrelated items and are goods independent of each other.
Items may be weak substitutes, in which the two products have a positive but low cross elasticity of demand. This is often the case for different product substitutes, such as tea versus coffee.
Items that are strong substitutes have a higher cross-elasticity of demand. Alternatively, the cross elasticity of demand for complementary goods is negative. As the price for one item increases, an item closely associated with that item and necessary for its consumption decreases because the demand for the main good has also dropped.
For example, if the price of coffee increases, the quantity demanded for coffee stir sticks drops as consumers are drinking less coffee and need to purchase fewer sticks. In the formula, the numerator quantity demanded of stir sticks is negative and the denominator the price of coffee is positive.
This results in a negative cross elasticity. Toothpaste is an example of a substitute good; if the price of one brand of toothpaste increases, the demand for a competitor's brand of toothpaste increases in turn. Companies utilize the cross elasticity of demand to establish prices to sell their goods. Products with no substitutes have the ability to be sold at higher prices because there is no cross-elasticity of demand to consider.

Cross-price elasticity of demand
The primary purpose of this paper is to provide updated estimates of domestic own-price, cross-price and income elasticities of demand and estimated price elasticities of supply for various California commodities. Flexible functional forms including the Box-Cox specification and the nonlinear almost ideal demand system are estimated and bootstrap standard errors obtained. Partial adjustment models are used to model the supply side. These models provide good approximations in which to obtain elasticity estimates.

Cross elasticity of demand XED measures the percentage change in quantity demand for a good after a change in the price of another. Explanation of XED Tea and coffee. These are goods which are used together, therefore the cross elasticity of demand is negative. If the price of one goes up, you will buy less of both goods.
