Question: In the world of fashion, the power to imitate a trendy look is the power to make money. Stores such as H&M and Forever 21 focus on imitating fashions wherever possible: As soon as they see that a new look is coming along, something people are willing to pay a high price for, they start cranking out that look. Do these imitation-centered stores make the supply of clothing more elastic or less elastic? How can you tell?
