| − | :[Teacher's Note: There is a mistake in this problem. The numbers are unrealistic and points were deducted for inadequate explanation. We will revisit this problem in the next homework.] | + | :[Teacher's Note: Unfortunately, there is a mistake in the ordering of the paired numbers used in this problem, which I realized only after grading the answers. The numbers were in the wrong order because a firm's profits should increase, not decrease, under this situation. All students correctly realized that the equilibrium must be where the profits are equal, either (50,50) or (75,75). If the profits increased for each firm when it increases profits, then the equilibrium would be (50,50), which would be the correct answer on an exam. But under the numbers provided, firms increase profits by reducing output, and (75,75) is the correct answer.] |
