Document Summary

Explain what the price elasticity of demand means. The ratio of the percent change in the quantity demanded over the percent change in the price as we move along the demand curve. Determine why the mid-point method is superior to the normal way we might calculate the percent change in order to determine a good"s elasticity. To avoid computing different elasticities for rising and falling prices and reach a consistent elasticity price. Explain why a good"s demand elasticity must be negative. Demand curves are downward sloping, so price and quantity demand always move in opposite directions. Explain what it means for a good"s demand elasticity to perfectly inelastic. Demand is perfectly inelastic when the quantity demanded does not respond at all to the changes in price. Explain what it means for a good"s demand elasticity to perfectly elastic. Demand is perfectly elastic when any price increase will cause the quantity demanded to drop to zero.

g. Given specific values for Own-Price Elasticity of Demand, can you determine whether demand for the good is elastic, inelastic, or unit elastic?

h. Given specific values for Cross-Price Elasticity, can you determine whether the two goods are substitutes or complements?

i. Given specific values for Income Elasticity, can you determine whether the good is a normal or inferior good?

j. Can you calculate each of these elasticities, such as in the homework?

k. Identify relatively elastic and inelastic demand curves?

l. List factors that may affect demand elasticity.

m. Indicate whether total revenue will increase or decrease as a result of a price change, depending on the demand elasticity?

From the scenario for Katrinaâs Candies, examine the procedure Herb will use to estimate the "demand model" for this product and comment on the expected price elasticity, income elasticity, and cross price elasticity of demand. That is, do you expect demand to be price elastic or inelastic? Will the income elasticity suggest Katrina Candies is a luxury or a necessary good? And, is there likely to be a strong cross price elasticity with the other products that Herb included in his demand model? Explain your answers. What can you determine about consumer demand for a product whose estimated demand elasticities are as follows: Price Elasticity of demand is -0.85 Income Elasticity of demand is 2.5 Cross Price Elasticity of demand with this product and your product is -2 I would like you to think about this simple formula for predicting the change in total revenue when there is a given percentage change in price. Using the example above, if ED (price elasticity of demand) is -.85, then a 10% increase in price will cause the quantity demanded to fall by 8.5%, (-8.5% / 10% = -.85). The Formula for Predicting % Changes in Total Revenue is: %ÎTR = %ÎQ + %ÎP where TR = Total Revenue, Q is Quantity Demanded and P = price. Using this formula, what would be the % Î in TR if ED is -.85 and the %ÎP is 10%?
