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 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. Using the midpoint method, what is the income elasticity of demand for pizza and what does the value indicate about the demand for pizza?
The income elasticity is 1 so pizza is a normal good.

good idea, since doing so helps to simplify the complex world and make it easier to understand

economists have different values and scientific judgment.

influencing the actions of buyers and sellers
One thing economists do to help them understand how the real world works is
make assumptions
Economists compute the price elasticity of demand as the
percentage change in quantity demanded divided by the percentage change in price.

raise the price of the cinnamon rolls.
Production possibilities frontiers are usually bowed outward. This is because
resources are specialized; that is, some are better at producing particular goods rather than other goods.
