The graph below shows a perfectly competitive firm in short run equilibrium, where the firm has chosen the output level maximizing its profit. Consider the level of profits being earned here, and what will happen over time. What will happen in the long run? Note that the horizontal demand curve, D1, is also equivalent to marginal revenue and price.
Group of answer choices
The market price will increase causing economic profits to increase
Demand will increase causing economic profits to increase
The market price will decrease until economic profit is zero
Suppose that many small firms operating in the perfectly competitive market set-up. All firms are identical and have the total cost function c (q)= 40+8q+(q^2/10), where q is the individual firm’s production amount. The market inverse demand function is described as P= A - (Q/50), where A>0 is constant, and Q is the market quantity. In the short-run equilibrium, there are 78 firms in the market, and firm’s maximum profit is $22.5
a) find the short-run equilibrium price
b) suppose that in the long-run, firms cost function is still the same C (q)= 40+8q+(q^2/10) (assume LR cost function has fixed component of 40) Find the long-run equilibrium number of firms? (Assume market demand in LR = market demand SR)
Suppose that the current price per unit of the good is 10 pounds. A perfectly competitive firm faces the cost function, C = 100 + (1/5)Q2, with marginal cost, MC, equal to (2/5)Q, where Q denotes the quantity produced. Find the profit-maximizing output for this firm in the short-run. Calculate profits. At the profit-maximizing output, is the firm covering its variable costs?

- Under conditions of perfect or pure competition, or close to those conditions, producers (firms) are what are called “price takers”. This means that the price for the product that they are selling is determined by the market. No matter how little or how much product they supply, they can sell all they want at that price. If they were to price their product higher, they will sell zero. Which of the following is true? The price is equal to marginal revenue but not average revenue The price is equal to marginal revenue and average revenue The price is equal to average revenue but is not equal to marginal revenue The price is above both marginal revenue and average revenuearrow_forwardConsider a perfectly competitive market for wheat in Dallas.
