Importance of elasticity in economics
adam
The elasticity of demand refers to how sensitive the demand for a good is to changes in other economic variables. The different types are: price elasticity, income elasticity, cross elasticity and advertisement elasticity.
Very good answer here: http://tutor2u.net/economics/content/topics/elasticity/elastic.htm
In economics , the cross elasticity of demand and cross price elasticity of demand measures the responsiveness of the quantity demand of a good to a change in the price of another good.
As many types as variables are used to calculate the elasticity. Elasticity is simply a relationship between rates of change of variables in equations.
1)price elasticity of demand 2)income elasticity of demand 3)cross elasticity of demand
Cross elasticity in economics, also referred to as cross-price elasticity is used to measure the changes of the demand of a certain commodity to the price changes of another good.

In economics, elasticity is the ratio of the change in one variable with respect to change in another variable, such as the responsiveness of the price of a commodity to changes in market demand or visa-versa. In terms of elasticity, a market or good can be described as elastic or inelastic as a means of describing its responsiveness to the change in another quantity. In economics, the definition of elasticity is based on the mathematical notion of point elasticity[citation needed]. For example, it applies to price elasticity of demand and price elasticity of supply, in which case the functions of the interest are Qd(P) and Qs(P). When working with graphs, it is common to put Quantity on x-axis and Price on y-axis, thus the function of the interest is x(y) rather than commonly used in mathematics y(x).
Price elasticity of demand is a measure used in economics to show the responsiveness, or elasticity, of the quantity demanded of a good or service to a change in its price.
Determining demand elasticity helps managers know how to schedule their goods. When they know their product isn't in demand, they can purchase another product instead.
