Researchers find that the income elasticity of poultry demand in Indonesia is 1.2. This implies that if income is expected to grow at 5%, then projected demand for poultry will:
a. Increase by 5% b. Increase by 6% c. Increase by 6.2% d. Increase by 4.2%
Refer to Figure 5-4. Suppose the point labeled B is the “halfway point” on the demand curve and it corresponds to a price of $5.00. Then, between prices of $4.99 and $5.01, the price elasticity of demand is
a. less than 1 but greater than zero. b. equal to 1. c. greater than 1. d. equal to zero. e. equal to infinity.
