b. Assuming that demand remains high, what do you anticipate will happen to the number of sushi restaurants in the city over the long run?

c. Suppose the sushi industry is a constant cost industry. Would you predict that the first sushi restaurant would be able to sustain positive economic profit over the long run? Explain your answer.

d. Using one graph of the market as a whole and one graph of a representative firm’s cost curves, illustrate your answers to parts a – c.

e. Local steakhouses suffer from the popularity of sushi and start incurring economic losses. What will happen to the number of steakhouses in town in the long run? Explain your answer.
