Nadia consumes two goods, food and clothing. The price of food is $2, the price of clothing is $5, and her income is $1,000. She always spends 40% of her income on food regardless of the price of food, clothing, or her income.
What is her price elasticity of demand for food?
What is her cross-price elasticity of demand for food with respect to clothing?
What is her income elasticity of demand for food?
Suppose you could buy shoes one at a time, rather than in pairs. What do you predict the cross-price elasticity for left shoes and right shoes would be? How does the cross-price elasticity concept inform a decision making process for the consumer?
Yesterday, the price of envelopes was $3 a box, and Julie was willing to buy 10 boxes. Today, the price has gone up to $3.75 a box, and Julie is now willing to buy 8 boxes. Is Julie's demand for envelopes elastic or inelastic? What is Julie's elasticity of demand?
To find Julie's elasticity of demand, we need to divide the percent change in quantity by the percent change in price.
