15. a. In the early 20th century, there were many local opera and theatre companies and other local providers of musical entertainment. With the rise of mass media and duplicative technologies (such as television, radio, and recordings), many of these local services disappeared. What do you think happened to the demand for the services of performers with extraordinarily high charm or talent (the Luciano Pavorrotis, Britney Spearses, and Tom Cruises of their day)? What do you think happened to the equilibrium price of the services of the most exceptional individuals?How do you think the price of the services of performers of somewhat less talent changed? b. Near the turn of the millennium, duplicative and transmission technology (the Internet, CDs) led to a further development: easy acquisition and duplication of music without paying the supplier. Assume that such piracy is cheap but not costless to consumers. Based on supply/demand analysis, what effect do you think this development had on the demand for the services of the very highest talent performers? Of performers with somewhat less talent?
