Question: A. There are some "status goods," like Rolex watches, that people want to own because they are expensive. In contradiction to the law of demand, if Rolex watches were less expensive, few "status-seeking" consumers would demand them. Reconcile status products or services with the law of demand. How does the existence of cheap "knock-off" imitations of Rolex watches fit with the law of demand?

B. Evidence suggests that babies are a normal good for lower income earners and an inferior good for higher income earners. Use the income elasticity of demand to explain what this means, using the definitions of "normal" and "inferior" goods.

C. Roses sell for about $40 a bouquet most of the year, and worldwide sales are 6 million bouquets per month. Every February, the price of roses doubles to $80 a bouquet, but the quantity of roses demanded and sold also increases, to 24 million bouquets per month. The cost of producing roses doesn't change throughout the year. Can you explain what else is going on that saves the law of demand?

D. Your business is about to launch an advertising campaign, announcing your new low prices. You hope the ads will bring in many more customers. Explain why you need to be concerned about your elasticity of supply.
