Using the midpoint method, the price elasticity of demand for a good is computed to be approximately 0.55. Which of the following events is consistent with a 20 percent decrease in the quantity of the good demanded? a. An increase of 11.0 percent in the price of the good b. an increase of 36.36 percent in the price of the good c. An increase in the price of the good from $11.00 to $20.00 d. an Increase in the price of the good from $20 to $31.00

Answer the following questions in your own words. Start a new thread while replying. 1. What are the determinants of price elasticity of demand? Explain the determinants. 2. What is the difference between inelastic demand and elastic demand? Provide an example of each from real life. 3. Refer to the graph below: Price 22 20 + 18 +- 16 + 14 B 12 10 + 4 Demand +++ 100 200 300 400 500 600 700 800 900 Buaxtity From the graph above calculate: a. Price elasticity of demand from point A to point B (use the mid-point method). Is it an elastic situation or an inelastic situation? b. Price elasticity of demand from point B to point C (use the mid-point method). Is it an elastic situation or an inelastic situation?

1. As a transit planner for the city of Miami, you must predict how many people ride the Miami Metrorail and how much money is generated from train fares. According to a recent study, the short-run elasticity of demand for Metrorail is 0.62 and the long- run elasticity is 1.59. The current ridership is 50,000 people per day. Suppose the city commission decides to increase fares by 10%. Predict the changes in train ridership over a one-month period and a five-year period. ANS: b. Over the one-month period, will total revenue increase or decrease? What will happen in the five-year period? ANS

Your firm receives revenue of $40MM per year from Product A and $90MM per year from Product B. The own- price elasticity of demand for Product A is -1.5. The cross-price elasticity of demand between Product A and Product B is -1.8. Suppose you increase the price of Product A by two percent:   a. How much will Product A’s revenue change?   b. How much will Product B’s revenue change?

Would you consider your demand for gas to be relatively elastic or inelastic? What changes do you make to your demand for gasoline when the prices start to climb up?

If the price elasticity of demand is equal to 2, a 1 percent increase in price will cause the quantity demanded to__by___ percent?

For each statement below, tell whether the statement is valid or invalid, and give a short explanation of your answer. Remember that your explanation will be related in some way to elasticity. 1. Coffee and tea should have a positive cross elasticity of demand. 2. Demand for Tide will be more elastic than demand for laundry detergents as a whole. 3. The government will prefer to put excise taxes on jewelry rather than on gasoline.
