It is not possible for any perfect competitive firm to produce a positive level of output in a range where MC is falling. This is because, according to one of the conditions of profit-maximisation, MC curve should be upward sloping or the slope of MC curve should be positive at the equilibrium level of output.

Let us take an example:-

At point Z price is equal to MC, but MC is falling and is negatively sloped. For any level of output more than Oq0, the firm is facing price > MC, which implies that the profit can be maximised by increasing the output level further.

Hence, the point ‘E’ is the equilibrium point, where a profit maximising firm would operate and produce Oq1 units of output and its profit will be maximised.

  Is there an error in this question or solution?
