Taylor Swift is a singer-songwriter whose pop album 1989 was the top-selling album of 2014, with 3.66 million copies sold in just its first 9 weeks of release. The path to success for pop musicians involves reducing the elasticity of demand that they face and building barriers to entry. That sounds like economic babble, but it has a lot of meaning. Using the language of economics and the concepts presented in this chapter, explain why lowering the elasticity of demand and building barriers to entry are exactly what Taylor Swift is trying to do. Lowering the elasticity of demand and building barriers to entry will benefit Taylor Swift because ____________. a. A smaller number of pop musicians allows more coordination among other musicians b. It increases her market competition and makes it possible to earn normal profits over time c. The lower the elasticity of demand, the more revenue she can make by lowering the price d. It increases her market power and makes it possible to earn economic profits over time
