Perfectly competitive firms will: increase output up to the point that the marginal revenue of an additional unit of output is equal to the marginal cost. increase output up to the point that the marginal revenue of an additional unit of output is greater than the marginal cost. always attempt to minimize average variable cost. maximize total revenue by using the marginal decision rule.

increase output up to the point that the marginal revenue of an additional unit of output is equal to the marginal cost.

Explanation:

In a perfect competition, there are many buyers and sellers of homogeneous products, and there is free entry and exit in the market.

This simply means that, in a perfectly competitive market, there are many buyers and sellers (price takers) of homogeneous products (standardized products with substitute) and the market is free (practically open) to all individuals or business entities that are willing to trade all their goods and services.

Generally, a perfectly competitive market is characterized by the following features;

1. Perfect information.

2. No barriers, it is typically free.

3. Equilibrium price and quantity.

4. Many buyers and sellers.

5. Homogeneous products.

Examples of a perfectly competitive market are the Agricultural sector, e-commerce and the foreign exchange market.

Perfectly competitive firms always strive to maximize profits by increasing their level of output, such that P = MC.

In a nutshell, in the long run equilibrium P = MR = MC.

Where;

P is the profit.

MR is the marginal revenue.

MC is the marginal cost.
