Because the firm's marginal cost curve determines the quantity of the good the firm is willing to supply at any market price, the marginal cost curve is the perfectly competitive firm's    Question 10 options:   a)  demand curve   b)  supply curve   c)  long run equilibrium curve    d)  product curve

PS4.2 (a) What Optimal Level of Output (q*) will a Firm Produce given the following? MC(q) = 3 + 2q Price (P) = $9 MC → Marginal Cost q→ Quantity (b) What is a Firm's Producer Surplus assuming the following? Area of Triangle = 1/2* Base * Height (c) Will a Firm be Earning a Positive, Negative, or Zero Profit in the Short-Run given the following? AVC (q) =3+q FC = $3 AVC → Average Variable Cost FC Fixed Cost

Suppose that the jackfruit industry is initially operating in long-run equilibrium at a price level of $5 per pound of jackfruit and quantity of 75 million pounds per year. Suppose a top medical journal publishes research that animal-alternative protein sources such as jackfruit could decrease your expected lifespan by 5 years. The publication is expected to cause consumers to demand jackfruit at every price. In the short run, firms will respond by Shift the demand curve, the supply curve, or both on the following graph to illustrate these short-run effects of the publication. 2 1 10 9 8 Supply Demand 0 0 + 15 30 45 60 75 90 105 120 135 150 QUANTITY (Millions of pounds) In the long run, some firms will respond by + 1 } Demand Supply until Shift the demand curve, the supply curve, or both on the following graph to illustrate both the short-run effects of the publication and the new long- run equilibrium after firms and consumers finish adjusting to the news. 2 1 10 9 Supply Demand B…

Under certain assumptions, the perfectly competitive market can be used to explain the three conditions that satisfy general equilibrium and pareto optimality. Identify these assumptions and carefully discuss the three (3) conditions for Pareto Optimality. Please provide in - text citations and academic references

In a perfectly competitive market: the market price is 28 Marginal cost (MC) = 2(Q) + 8 average total cost at equilibrium is 28, and average variable cost at equilibrium is 7 The profit maximizing price is Number The profit maximizing quantity is Number :Total revenue is Number Total cost is Number Average fixed cost is Number Total fixed cost is Number Total profit/loss is Number Marginal ravenue is Number At this market price,over time, firms would: 1. Enter the industry 2. leave the industry 3. There is no incentive to enter or leave the industry. Number (assume all firms have the same cost structure) :At the market price, could this be a long run equilibrium price? (if yes=1, no=D2) (assume all firms have the same cost structure) Number

Suppose that the market for air fresheners is a perfectly competitive market. The following graph shows the daily cost curves of a firm operating in this market. 40 36 Profit or Loss 32 28 24 ATC 16 12 AVC MC + 0 2 4 8 10 12 14 16 18 QUANTITY (Thousands of air fresheners) In the short run, at a market price of $20 per air freshener, this firm will choose to produce air fresheners per day. 20 20 8. PRICE (Dollars per air freshener)

Which of the following is NOT a charactersitic of the model of perfectly competitive market? a) Many sellers produce an identical product. b) Firms can increase their prices by reducing their product. c) Firms have freedome of entry into the market. d) No signs firm can influence the market price.
