Question
Firm Alpha operates in a
- How does Firm Alpha determine its profit-maximizing quantity of output? Explain.
- Draw correctly labeled side-by-side graphs for Firm Alpha and the market it operates in. Label the axes and all of the following:
- Market price (PE) and market quantity (QE)
- The firm's quantity of output (Qe)
- The firm's
average total cost (ATC)
- Completely shade the area of the firm's total cost.
- Identify whether the following increase, decrease, or remain constant as the market moves to long-run equilibrium:
Market equilibrium quantity- Market
equilibrium price
- Assume the product that Firm Alpha produces has a negative externality. Draw the marginal
social cost (MSC) on the market graph from part (b). - Will the unregulated market produce more or less than the socially optimal quantity?
- Label the socially optimal quantity (Qso) for the market on your graph from part (b).

- in a perfectly competitive market with a constant cost industry, there are currently 100 identical firms, each with the total cost function TC(Q) = Q^2 + 4Q + 36. The market demand is Q = 1800 – 50p. a. What is the price at the short-run equilibrium? What is the net profit/loss of each firm at this price? b. In the long run, how many firms will enter into /exit from the market?arrow_forwardAnswer both parts a and b please. Part a) True or False: In a competetive market, a firm's short run supply curve is sloping upwards due to diminishing returns of the variable input. Explain why. Part b) Are long run supply curves always upward sloping? Explain why or why not with a graph.arrow_forwardThe intersection of the average variable cost curve and the marginal cost curve, which shows the price where the firm would lack enough revenue to cover its variable costs, is called the: Shutdown point Equilibrium Profit Lossarrow_forward
- In the long-run equilibrium of a perfectly competitive market with identical firms, which of the following will be true? There will be no incentive for firms to enter or exit the market. Every firm will produce the quantity of output at which its average total costs are minimized. Every firm will earn 0 economic profit. All of the other choices will be true. Every firm's marginal cost will equal its marginal revenue.arrow_forwardFirm Alpha operates in a perfectly competitive market in a constant-cost industry and is earning negative economic profit.

Draw the marginal social cost (MSC) on the market graph from part (b). Will the unregulated market produce more or less than the socially optimal quantity? Label the socially optimal quantity (Qso) for the market on your graph from part (b).arrow_forwardConsider a market structure of perfect competition where firms have a U-shaped average cost curve. Describe the transition from short-run equilibrium to long-run equilibrium, noting the assumptions that are made in this modelarrow_forward
- Assume that the medical screening industry is perfectly competitive. Consider a typical firm that is making short-run losses. Suppose the medical screening industry runs an effective advertising campaign which convinces a large number of people that yearly CT scans are critical for good health. How will this affect a typical firm that remains in the industry? The firm's marginal revenue curve and average cost curve shift upwards in response to the increase in market price and advertising expenditure. The firm increases output until it starts breaking even. The marginal revenue curve shifts upwards, the firm's output increases along its marginal cost curve, it expands production and eventually starts making profits. The marginal revenue curve shifts upwards, the firm's output increases along its marginal cost curve, it expands production until it breaks even. The firm's supply curve shifts right and its marginal revenue curve shifts upwards as the market price rises and ultimately the…arrow_forwardConsider a kettle firm A in a perfectly competitive market.
