Why would a producer decide to produce in a competitive market in which she will earn zero profit in the long run? Choose one: A. Because at zero profit, with her revenue, she can cover all her costs—explicit and implicit (opportunity cost). B. Because the zero profit in the long run is, in fact, zero accounting profit, and it matters only in the books. C. Because in the short run, her profit is always positive. D. Because the producer has a high cost of exiting this market, and it is better for her to continue operating at zero profit.

Option A : Because at zero profit, with her revenue, she can cover all her costs—explicit and implicit (opportunity cost).

Explanation:

Perfectly Competitive Market

This is simply a market the market participants are said to be price takers that is no consumption decisions by individual consumers and no production decisions by individual producers can be able to affect the market price of a good.

Perfectly Competitive Industry

This is simply an industry where producers are said to be price takers.

Explicit Costs

These are costs that are simply known as "out-of-pocket" costs or in accounting costs. They are an individual's fixed and variable costs of doing business.

Implicit Costs

These are costs that do not partains to monetary payment as they are the opportunity costs of doing business.

It is said that at zero profit, the revenue covers all the costs, including the implicit ones. The fact that her implicit costs are covered shows that no outside option or opportunity that is superior to the zero economic profit option is chosened.
