Homework Assignment #1

1. Moving along a demand curve, quantity demanded decreases 21 percent when price increases

by 7 percent.

a. The price elasticity of demand elasticity is calculated to be ____________.

b. Given the price elasticity calculated in part a, demand is ______________. (elastic,       inelastic, unitary elastic) along this portion of the demand curve.

c. For this interval of demand, the percentage change in quantity is _____________          (greater than, less than, equal to) the percentage change in price.

2. Fill in the blanks:

a. The price elasticity of demand for a firm’s product is equal to 0.5 over the range of        prices being considered by the firm’s manager. If the manager decreases the price of the            product by 12 percent, the manager predicts the quantity demanded will _____________         (increase, decrease) by ______ percent.

b. The price elasticity of demand for an industry’s demand curve is equal to 0.5 for the     range of prices over which supply increases. If total industry output is expected to   increase by 6 percent as a result of the supply increase, managers in this industry should            expect the market price of the good to _____________ (increase, decrease) by ______        percent.

3. The price elasticity of demand for a firm's product is 2.25 over the range of prices being

considered by the firm's manager.

a. If the manager increases the price of the product by 8 percent, the manager predicts       that quantity demanded will _____________ by _______ percent.
b. If the manager wishes to increase sales by 25 percent, the manager predicts the price of             the product must be _____________ by _______ percent.

4. Boeing estimates the elasticity of demand for new commercial jets is 1.25. State whether the  following statements are either true or false.

a. "The price effect dominates the quantity effect." _________ (true, false)

b. "A 4 percent increase in the number of jets sold will require a 5 percent decrease in the price of jets." ________ (true, false)

c. "A 5 percent decrease in the price of jets will increase Boeing's total revenue." ______.

5. Use the information provided in the diagram below to fill in the blank spaces. When the price of good

Xis \$75, calculate the following elasticities:

a. Panel A shows how the demand for X shifts when income (M) increases from \$33,000   to \$35,000.  The income elasticity of demand for X equals _____________. Good X is a(an)  _________________ good.

b. Panel B shows how the demand for X shifts when the price of related good Y decreases            from \$80 to \$60. The cross-price elasticity equals _____________.  Goods X and Y are ________________. [use the mid-point approach in answering a & b]

6.  Using the supply data in the schedule shown below, complete the table by computing the price elasticity of supply coefficients between each set of prices.  Indicate whether supply is elastic, inelastic or unitary at each set of prices. (Use the mid-point formula)

 Price Quantity supplied Elasticity coefficient Character of supply \$11 130 _____ _____ 9 110 _____ _____ 7 90 _____ _____ 5 70 _____ _____ 3 50
