- An oligopoly firm

- A perfectly competitive firm

- A monopolistically competitive firm

- A monopsonist

Solutions

Expert Solution

Average revenue is always equal to price.

So, average revenue curve, in a sense, indicates quantity sold at each price.

The demand curve indicates the same preposition.

Due to this, AR curve and demand curve are the same.

As we know that, in case of perfectly competitive firm, demand curve coincides with the marginal revenue curve because a perfectly competitive firm is a price taker and it can sell as much as it wants at the given price.

So, demand curve is a horizontal straight line at the given price.

With price being given, each successive unit sold brings same revenue, this results in MR curve being horizontal straight lineat the given price.

Thus, both demand curve and MR curve coincides.

Since, demand curve is same as the AR curve, it can be stated that it is in case of perfectly competitive firm does the average revenue curve coincide with the marginal revenue curve.

Thus, the correct answer is the option (3).

Which of the following statement is true? The entire marginal cost curve becomes the firms short-run supply curve. Market demand is infinitely elastic in all competitive industries. The average variable cost curve represents the short run supply curve for competitive firms. -- Normal profits are a cost of production. (I chose this one. Is this right?) Competitive firms can earn no economic profits during the short run period of time.
