If we observe that when consumers' incomes rise by 10%, the quantity demanded of ice cream increases by 5%, then ice cream is an inferior good.

A key determinant of the price elasticity of supply is the

Scenario 5-1 Suppose that when the average college student's income is $10,000 per year, the annual quantity demanded of Patty's Pizza is 50 and the annual quantity demanded of Sue's Subs is 80. Suppose that when the price of Patty's Pizza increases from $8 to $10 per pie, the quantity demanded of Sue's Subs increases from 80 to 100. Suppose also that when the average student's income increases to $12,000 per year, the annual quantity demanded of Patty's Pizza increases from 50 to 60. -Refer to Scenario 5-1. Using the midpoint method, what is the income elasticity of demand for pizza and what does the value indicate about the demand for pizza?

Suppose the price elasticity of demand for good A is 1.25. If the price of good A increases by 20%, what will be the resulting percentage change in quantity demanded for good A?

The income elasticity of demand is defined as the percentage change in quantity demanded divided by the percentage change in price.
