1. If the price decreases by 4 percent. As a result, the quantity demanded increases by 12 percent. The
price elasticity of demand is - Answers 12%/-4%=-3% Change in % Quantity demanded/change in %
Price, Greater than 1 is elastic, less than 1 is inelastic, equal to 1 is unit elasticity
2. What is the relationship between elasticity and revenue - Answers When the price changes,
consumers demand changes based on the price change. The response could be very dramatic (elastic) or
not very responsive to change in price (inelastic). When demand is elastic, the relationship between
price and revenue will be in the opposite direction. In elastic cases greater than one, when price
increases elasticity, revenue decreases. When demand is inelastic, less than one, and price goes up,
revenue goes up. Unit elasticity, no change for revenue.
3. A 7 percent reduction in the price of a product has zero effect on the dollar amount of consumer
expenditure on the product. The price elasticity of demand is - Answers one, unit elastic.
4. What does the price elasticity of demand coefficient measure - Answers the responsivity of
consumers with regards to any price change
5. define the price elasticity of demand - Answers the responsiveness of the quantity demanded of a
product or service when its price is changed by one unit. The nature of the price elasticity of demand
can be elastic, inelastic, or unit elastic.
6. What is characteristic of the demand for a commodity that is elastic - Answers many substitutes,
competitive markets, high percentage of income, bought frequently
7. What is characteristic of the demand for a commodity that is inelastic - Answers no substitutes, little
competition, bought infrequently, small % of income, short-run, location
8. What is unit elastic - Answers The elasticity of demand is always one, regardless of price change.
9. When the price of a good goes up and demand is unit elastic, what would happen to the total revenue
- Answers it is not affected and does not change.
10. What is the basic difference between the short run and the long run - Answers short run means time
frame where at least one resource or production is fixed, long run all factors of production are variable.
EX: Fast food restaurant, fixed size in short run unless you build in the long run.
11. What is the relationship between the total product and marginal product? - Answers total product
means total level of production/ marginal product means additional product. As the marginal product or
labor is up and up, total product goes up. The change in total product means an increase in the marginal
product.
