Document Summary

Cross-price elasticity of demand measures how the quantity demanded of one good responds to a change in the price of another good. Price elasticity of supply measures how much the quantity supplied responds to changes in the price. Supply of a good is said to be elastic if the quantity supplied responds substantially to changes in the price. Supply is said to be inelastic if the quantity supplied responds only slightly to changes in the price. A key determinant of the price elasticity of supply is the time period being considered. Supply is usually more elastic in the long run than in the short run. Price controls are usually enacted when policymakers believe that the market price of a good or service is unfair to buyers or sellers. Price ceiling - a legal maximum on the price at which a good can be sold (for buyers)

Discussion #1

The law of demand states that a fall in the price of a good raises the quantity demanded, and the increase in price leads to a decrease in quantity demanded. The price elasticity of demand measures the responsiveness of the quantity demanded to a change in price. Demand for a good is said to be elastic if the quantity demanded responds substantially to changes in the price, and the percentage change in quantity demanded is greater than the percentage change in price. Demand is said to be inelastic if the quantity demanded responds only slightly to changes in the price, which indicates that the percentage in price is greater than the percentage in quantity demanded.

However, the extent of responsiveness of quantity demanded to a change in price depends on the nature of a particular good or service in the market. The price elasticity of demand partly depends on the availability of close substitutes. When a large number of substitutes are available, consumers respond to a higher price of a good by buying more of the substitute goods and less of the relatively more expensive good. In addition, goods or services that are considered necessities tend to have less elastic (more inelastic) demand, whereas goods or services that are considered luxuries have more elastic (less inelastic) demands.

Explain why the demand for the good or service provided by the organization you work for is elastic or inelastic. How does this influence pricing decisions?
Provide examples on how the availability of close substitutes affects price elasticity of demand.
Give specific examples of necessities or luxuries, and explain how they affect price elasticity of goods or services.

Potential Matches:

1 : measures the responsiveness of the quantity supplied of a good to changes in the price of that good

2 : a formula that measures the responsiveness along a specific section (arc) of a supply or demand curve and measures the "average" price elasticity between two points on the curve.

3 : measures the responsiveness of the quantity supplied of a good to changes in the price of the related good

: Cross-Price Elasticity of Supply

: Arc Elasticity
