In this course we learned about the Zero-Profit Condition in the long-run equilibrium in two of the four market structures we covered in this course. A) Why does the Zero-Profit Condition not exist in our monopoly model? Explain why this is the case. B) We stated that a firm under monopolistic competition has a pathway to escape the zero- profit condition that isn't there for a firm in perfect competition. What is the key difference between the two models that makes that so? Explain why that is the case. Please separate your answers to part (A) and part (B) for ease of grading.
