Which of the following is not an assumption economists make when using the model of perfect competition? group of answer choices there is easy entry and exit. each firm sets it price equal to its average total cost. the products of each firm in a particular market are identical. firms seek to maximize profits.

Each firm sets it price equal to its average total cost.

Explanation:

In economic theory, perfect competition is a market with a large number of sellers and buyers, producing similar products and having a small market share that does not affect prices. Let's explain the characteristics of the perfect competition :

1) manufacturers of identical products. . .

Products in the perfect competitive market are completely substitute. In other words, products and services offered by vendors do not differ from one another in terms of quality or character.. . .  

2) the firm has a small market share that will not affect prices. . .

No vendor in this market has the ability to influence prices by increasing or decreasing production. Also, no buyer can reduce the supply of goods and lead to lower prices

3)Market where there are many buyers and sellers. . .

The above feature is directly related to this. Thus, if there is a seller or buyer in the market (such as monopoly or monopsony), it can easily affect the market price. However, in perfect competition, every seller and buyer must act based on market prices.

4)There is no obstacle to entering and leaving the market. . .

That is, access to the market is extremely easy and at the same time neither the state nor the old market participants have a barrier for the new participant.

5)Perfect information. . .

Every market participant knows the prices, quality and production methods.  

6) Zero transaction costs...

Buyers and sellers do not bear any transaction costs (contract costs, etc.) during the purchase of goods and services. . .

7) Maximizing profits. . .

In a highly competitive market, the main purpose of firms is to maximize their profits, without any serious obstacles. In a fully competitive market, maximum profits are earned when marginal costs are equal to marginal revenue.

As you see there is information above about the easy entry and exit, the identical products and maximizing profits but nothing about the equal prices to average costs.
