They are guaranteed a profit.
The market supply curve of a product is more price elastic than the supply curve of one of the firms in the market. The reason is that for any given price change, the market quantity response reflects the change in output of all the firms in the market.
The firm supply curve is horizontal in a perfectly competitive market because individual firms are price takers; they sell their products at the market price set by overall supply and demand. At this price, firms can sell any quantity they choose without affecting the market price. Therefore, they will supply as much as they can produce at that price, leading to a horizontal supply curve. If the price falls below this level, firms would not cover their costs and would reduce output to zero.
The minimum is price=average cost below this price supply=0
All firms do have the power to fix a price ,but insteadof doing so,in a competitive market situation firms fix a price which is equal to the average price charged by all firms in an industry,ie,it collects all the prices firms with same product and compute the average.
Posted pricing from the big three is $170 per ton. However, there are some supply contracts in place, some volumes discounts and inflated estimates. Assume $140-160
The seasonal nature of many commodities would lead to wide variation in supply and price without these contracts.
What factors usually affect pricing?
firms have more of an incentive to increase output
Firms have more of an incentive to increase output
Firms are considered price takers in a perfectly competitive market. In this market type, numerous small firms sell identical products, and no single firm has the power to influence the market price. Because of the high level of competition and the homogeneity of products, firms must accept the market price determined by supply and demand.
a perfectly competitive firms supply curve will be the portion of the marginal cost curve which lies above the average variable cost curve (AVC)..this will be due to the firms unwillingness to supply below the price in which they could cover their variable costs
OPEC charges what the market will allow. It regulates the price by regulating the supply.
