Part (A) (1) The conditions of perfect competition are: 1. There must be many firms in the market, and each of them is small in terms of sales comparing to the total market. Thus, firms are price-takers because they cannot affect the market price. 2. All firms in the market produce non-differentiated or homogeneous products. 3. In perfectly competitive market should not be restricted so any firm will be able to enter and exit the market easily without preventing barriers. (2) In the perfectly competitive market, the short-run industry supply is always upward-sloping and the supply prices along the industry supply curve give the marginal costs of production for every firm contributing to industry supply. The short-run supply curve for …show more content…

Here is the explanation for the graph: When market price is more than ATC, that mean the firm makes a profit. When the price is equal to ATC, the firm reach the breakeven where total revenue = total cost. When the price is less than ATC, that means the firm experiences a loss. (4) The goal of the producer in the short-run is profit maximizing or loss minimizing. The profit maximizing or loss minimizing rule for a firm under the conditions of the perfect competition market is simple and intuitively appealing. The output should be set at the level where the difference between total revenue and the total cost of producing that output is the greatest. In other word, marginal costs equal to marginal revenue. Part (B) As known that the firm in the short run has at least fixed factor, and it seeks to maximize profit to minimize loss by adjusting the level of output. The firm should produce when the difference between total revenue and total cost is profitable or the loss is less than the fixed cost. However, it needs to stop producing or even shut down in the short-run when its loss exceeds its fixed costs. By shutting down, the firm’s loss will equal the fixed costs of producing. Part
