Tracey usually pays a price between $6 and $10 per pound of rice. Her monthly total expenditure on rice increases as the price decreases. What does this implyabout her price elasticity of demand for rice?
If Neil's elasticity of demand for hot dogs is constantly 0.9, and he buys 4 hot dogs when the price is $1.50 per hot dog, how many will he buy when the price is $1.00 per hot dog?
This time, we are using elasticity to find quantity, instead of the other way around. We will use the same formula, plug in what we know, and solve from there.

- Estimates presented in Exhibit 5 show that Android users have a higher price elasticity of demand for apps in the Google Play Store than do iPhone users in the Apple App Store. Why might Android users tend to be more sensitive to app prices than iPhone users?

We can divide normal goods into two types: Those whose income elasticity is less than one and those whose income elasticity is greater than one. Think about products that would fall into each category. Can you come up with a name for each category?arrow_forwardIncome Effects depend on the income elasticity of demand for each good limit you buy. If one of the goods you buy has a negative income elasticity, that is, it is an inferior good, what must be true of the income elasticity of the other good you buy?arrow_forward
