Availability of substitutes, whether it is a neceesity or luxury, proportion of the purchaser's budget consumed by that item and permanent or temporary price changes.
The price elasticity of demand is measured by calculating the percentage change in quantity demanded in response to a percentage change in price. Factors considered in determining price elasticity of demand include the availability of substitutes, necessity of the good, and time period for adjustment.
distinguish between price elasticity of demand and income elasticity of demand
What are the determined factors of price elasticity of demand
1)price elasticity of demand 2)income elasticity of demand 3)cross elasticity of demand
Cross price elasticity of demand measures the responsivenss of demand for a product to a change in the price of another good.
Unitary elasticity is when the price elasticity of demand is exactly equal to one.
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.
The price elasticity refers to the change in demand due to the change in price. The income elasticity of demand on the other hand refers to the change in demand due to the change in income.
role of price elasticity of demand in managerial decisions
Very good answer here: http://tutor2u.net/economics/content/topics/elasticity/elastic.htm
No, cross price elasticity of demand and price elasticity of demand are not the same. Price elasticity of demand measures how the quantity demanded of a good responds to changes in its own price, while cross price elasticity of demand measures how the quantity demanded of one good responds to changes in the price of another good. The former focuses on a single product, while the latter examines the relationship between two different products, indicating whether they are substitutes or complements.
Elasticity coefficients are measures that indicate how the quantity demanded or supplied of a good responds to changes in other factors, typically price or income. The main types include price elasticity of demand, which measures the responsiveness of quantity demanded to price changes; price elasticity of supply, which assesses how quantity supplied responds to price changes; income elasticity of demand, indicating how demand changes with consumer income; and cross-price elasticity of demand, which measures the change in demand for one good in response to the price change of another good. Each coefficient helps businesses and policymakers understand consumer behavior and market dynamics.
