a. If the $5 price described in the news clip were adopted, would the market be efficient or inefficient? Explain.

b. Is the $5 price described in the news clip a competitive market price? Explain.

The price of streaming services has been $10 a month or zero. Amazon and Pandora Media are poised to change the streaming scene. Pandora is a streaming Internet radio service, and its new $5 version will be more like Spotify and Apple Music, which let users create their own playlists. Amazon, which offers limited on-demand music for $99 a year, is expected to expand its catalog and offer it for $10 a month or $5 a month for customers who use the Echo, Amazon’s voice-activated speaker system.

Assume that the marginal social cost of streaming is zero. (This assumption means that the cost of operating a streaming service doesn’t change if more people stream more songs.)
