1. In a perfectly competitive market, what is the effect of an increase in marginal cost on equilibrium price and quantity? Under what conditions does the increase in equilibrium price equal the increase in marginal cost?
2. If equilibrium price increases by less than an increase in marginal cost, what is the response by a competitive firm in setting its output?
Homework Answers
Answer 1. )
If there is an increase in marginal cost, then the equilibrium price will also increase because in a perfectly competitive market marginal cost is equal to price. Assuming the good to be a normal good, the equilibrium quantity will decrease with an increase in price.
Answer 2.)
If the increase in price is less than an increase in marginal cost, then the decrease in output would be less than what it was supposed to be. The competitive firm would decrease its output at a lower rate.

The market for fertilizer is perfectly competitive
The market for fertilizer is perfectly competitive. Firms in the market are producing output, but they are currently making economic losses. a. How does the price of fertilizer compare to the average total cost, the average variable cost, and the marginal cost of producing fertilizer? I would think that average total cost and the average variable cost would be greater than the price of fertilizer. The marginal cost would be equal to the price of fertilizer. Is this correct? c....

Consider a perfectly competitive market with many identical firms. Each firm has a long-run marginal cost function given by LRMC(y) = y ^2 + 1. We do not know the firms’ LRAT C function, but we know that at a quantity of 3 it is equal to LRMC. In other words: LRAT C(3) = LRMC(3). (a) Find an expression for an individual firm’s long-run inverse supply curve: this will be p as a function of y. Note that it will...

The demand curve for a perfectly competitive firm options: is upward sloping. is perfectly horizontal. is perfectly vertical. maybe downward or upward sloping, depending upon the type of product offered for sale. In the short run, the best policy for a perfectly competitive firm is to Question 17 options: shut down its operation if the price ever falls below average total cost. produce and sell its product as long as price is greater than average variable cost. shut down its...

a) Using both market and firm graphs for a perfectly competitive industry, show the effect of an increase in consumers’ income taxes. Assume the representative firm and market begin in long run equilibrium. Illustrate the short run effect on price, output, and profits, assuming this firm does not shut down. Label your graphs and explain your answer. b) Assuming the representative firm does not withdraw from the market, show the long run effect on price, output, and profits. Label your...
