Factors that increase the price elasticity of supply are: · The good has a constant or very gently rising opportunity cost of production. · More time has passed since the price of the good changed. · The good can be stored. Topic: Factors that influence the price elasticity of supply Skill: Level 2: Using definitions Section: Checkpoint 5.2 Status: Old AACSB: Written and oral communication 4) How does elasticity of supply differ for a product that can be stored, compared to a product that cannot be stored? Answer: A product that can be stored can be withheld from the market for a time when the price falls and can be quickly supplied to the market from the inventory when the price rises. Hence the quantity supplied of the product can be quickly and markedly changed and so the supply is elastic. A product that cannot be stored, especially if it is perishable, cannot be withheld from the market when the price falls because it will spoil. In addition, when the price rises it cannot be supplied from the inventory because there is no inventory. Hence the quantity supplied of the product that cannot be stored cannot change much and is therefore less elastic.

15) Studies have shown that the price elasticity of demand for necessities, such as food, are higher in developing countries and lower in developed countries. What is the reason for this difference in elasticity?
One of the determinants of elasticity is the proportion of income spent on a good or service. The higher the proportion of income spent on a good, the larger the price elasticity of demand for that good. People in developing countries have low incomes and therefore spend a large part of it on food. For example, in Tanzania 62 percent of income is spent on food. On the other hand, in United States only 12 percent of income is spent on food. The price elasticity of demand for food therefore will be larger in developing countries as compared to developed countries.

Answer: Moving down along a downward-sloping, linear demand curve, the elasticity of demand falls in value.

Answer: The effect of a price hike on total revenue depends on the elasticity of demand. If the demand is elastic, then total revenue will decrease because the decrease in the quantity demanded will outweigh the effect of the higher price. If the demand is inelastic, then total revenue will increase. In this case, the decrease in the quantity demanded is proportionally less than the increase in price and so the higher price leads to increased total revenue. Finally, if the demand is unit elastic, then the higher price does not change the total revenue. The percentage decrease in the quantity demanded just equals the percentage increase in the price and so the two effects just offset each other. The total revenue does not change.

6) Is supply more elastic or less elastic as more time passes after a price change? Explain your answer.
Supply becomes elastic as more time passes after a price change. Consider the case of an increase in price. As more time passes, producers have time to gather more resources, such as building additional factories, and to implement new production techniques. Hence as time passes, the quantity supplied increases. Topic: Elasticity, time since the price changed Skill: Level 2: Using definitions Section: Checkpoint 5.2 Status: Old AACSB: Reflective

Page 546 Copyright © 2015 Pearson Education, Inc. 7) If the percentage change in quantity demanded is greater than the percentage change in price, can you determine if the demand is elastic, unit elastic, or inelastic? Explain your answer.
The demand is elastic. The formula for the price elasticity of demand is the percentage change in the quantity demanded divided by the percentage change in the price. And, if the elasticity of demand exceeds one, then the demand is elastic. In this case, the percentage change in the quantity demanded is larger than the percentage change in the price, so the elasticity of demand will be greater than one. Hence the demand is elastic. Topic: Elastic demand Skill: Level 2: Using definitions Section: Checkpoint 5.1 Status: Old AACSB: Written and oral communication 8) Does the fact that the price elasticity of demand for a good is inelastic violate the law of demand? Answer: No, if the demand is inelastic, when the price falls, the quantity demanded increases, but by a smaller percentage than the percentage fall in price. Thus the negative relationship between the price and the quantity demanded remains, and the demand curve still slopes downward, which is the law of demand. Topic: Inelastic demand Skill: Level 2: Using definitions Section: Checkpoint 5.1 Status: Old AACSB: Written and oral communication 9) What factors determine the size of the price elasticity of demand? Answer: The factors that determine the size of the elasticity of demand can be classified into the availability of substitutes for the good and the proportion of income spent on the good. The more substitutes for a good, the more elastic its demand. Luxuries have more substitutes than necessities, and so the elasticity of demand for luxuries exceeds that for necessities; narrowly defined goods have more substitutes than broadly defined goods, and so the elasticity of demand for narrowly defined goods exceeds that for broadly defined goods; and, the more time that has elapsed since a price change, the more substitutes consumers can find, and so the elasticity of demand is larger the more time passes. Income also plays a role because the larger the proportion of consumersʹ incomes spent on a good, the larger is its elasticity of demand.

Answer: The price elasticity of demand is a measure of how responsive the quantity demanded is to a change in price. If a good has many substitutes, it is easy to switch away from it when its price rises. Hence a rise in price will substantially decrease the quantity demanded. Similarly, when its price falls, consumers can switch into it and away from many other (substitute) products. Hence a fall in price will substantially increase the quantity demanded. Because changes in price have major effects on the quantity demanded, the demand is elastic.

Page 552 Copyright © 2015 Pearson Education, Inc. 28) Suppose the price elasticity of demand for bouquets of flowers is 4.0. You are charging $8 per bouquet. If you want to increase the quantity of bouquets you sell by 20 percent, what price should you charge?
The price elasticity of demand = (percentage change in the quantity demanded) ÷ (percentage change in price). Using the numbers in the problem gives 4.0 = (20 percent) ÷ (percentage change in price), where 20 percent is the desired increase in the quantity of bouquets demanded. Therefore, rearranging the formula shows that (percentage change in price) = (20 percent) ÷ 4.0 = 5 percent. In order to increase the quantity demanded, the price needs to be decreased, so the price needs to be decreased by 5 percent. Next, 5 percent of $8 is ($8) × (5 percent) = $0.40. Thus the price needs to be decreased to $7.60 per bouquet. Topic: Elasticity formula Skill: Level 4: Applying models Section: Checkpoint 5.1 Status: Old AACSB: Analytical

The price elasticity of demand = (percentage change in the quantity demanded) ÷ (percentage change in the price). Use the midpoint method to calculate the percentages. So the percentage change in the quantity demanded is (10 million - 8 million) ÷ (9 million) = 22 percent and the percentage change in the price is ($7 - $5) ÷ ($6) = 33 percent. Therefore the elasticity of demand equals (22 percent) ÷ (33 percent) = 0.67. Demand is inelastic because the price elasticity of demand is less than 1.

24) Recently the governor of Vermont proposed that cigarette taxes in Vermont should be increased substantially, from 44 cents a pack to 66 cents a pack. He estimates that Vermont can raise $20 million in revenue from this tax hike. He also pointed out that the neighboring state of New Hampshire was considering an increase in cigarette taxes. a. How can it be that an increase in cigarette taxes will increase tax revenue, because, after all, a higher tax will increase cigarette prices and thereby decrease the quantity demanded? b. If New Hampshire chooses not to increase cigarette taxes, is it likely that Vermont can still raise $20 million in tax revenue? Why or why not? Explain
a. The governor knows that cigarettes have an inelastic demand. If the price of cigarettes increases because of a tax, smokers will not decrease their consumption of cigarettes substantially. The percentage change in the quantity will be less than the percentage change in the price and the total tax revenue will increase. b. If New Hampshire does not increase its taxes, it is less likely that Vermont will be able to raise the $20 million in tax revenue. The reason is because for many people cigarettes from New Hampshire are a good substitute for cigarettes from Vermont. Thus many people from Vermont will buy their cigarettes in New Hampshire, thereby decreasing the total increase in tax revenue in Vermont.
