Economists define normal goods as having a positive income elasticity. 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?

Income 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?

Suppose that your demand schedule for pizza is as follows: a. Use the midpoint method to calculate your price elasticity of demand as the price of pizza increases from 8 to 10 if (i) your income is 20,000 and (ii) your income is 24,000. b. Calculate your income elasticity of demand as your income increases from 20,000 to 24,000 if (i) the price is 12 and (ii) the price is 16.
