The chapter states that your consuming a Big Mac does not create an externality. But suppose you arrive at your favorite McDonald's at lunchtime and get in a long line to be served. By the time you reach the counter, there are 10 people in line behind you. Because you decided to have a Big Mac for lunch-instead of, say, a pizza-each of those 10 people must wait in line an additional 2 minutes. Is it still correct to say that your consuming a Big Mac creates no externalities? Might there be a justification here for the government to intervene in the market for Big Macs? Briefly explain.
