Document Summary

The law of demands says an increase in price causes a decrease in quantity demanded (vice versa. When qd responds strongly to a change in p, demand is elastic. When qd responds weakly to a change in p, demand is inelastic. The formula is ed= percentage change in quantity demanded of product x/ Percentage change in the price of product x. The price elasticity coefficient: price elasticity of demand, use percentages, unit free measure, compare responsiveness across products. Interpretation of elasticity of demand: ed> 1 demand is elastic, ed= 1 demand is unit elastic, ed< 1 demand s in elastic. For all straight line and most other demand curves: demand is more elastic toward the upper left, demand is less elastic toward the lower right. Determinants of price elasticity of demand: substitutability, proportion of income, luxuries versus necessities, time. Applications of price elasticity supply: antiques and reproductions, volatile gold prices.

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%?

In this question, we will determine the price elasticity of demand using both the coefficient of elasticity and the total revenue test.

Use the demand schedule in the table below to answer the following questions.

Quantity Demand	Price
10	200
20	150
30	100
40	50
50	25

a) Calculate the total revenue for each row in the demand schedule. indicate whether total revenue increases or decreases between each row int eh demand schedule. use the total revenue test to classify each price/quantity change as elastic, inelastic, or uni-elastic.

b) calculate the own price-elasticity coefficient for each row in the demand schedule. use the coefficients you calculate to classify each price/quantity change as elastic, inelastic, unit elastic.

in your answer it will be useful to recall that the midpoint formula for percentage change is:

%change midpoint = (final - initial) / ((finial + initial)/2)

and own price elasticity can be calculated by using the formula

Ed= (percentage change in quantity demand of product x) / (percentage change the in the price of product x)

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.
