Q12: In a given market, demand is described by the equation Q_D = 1,800 - 10P and supply is described by Q_S = 200 + 10P.

(a) Determine the equilibrium price and quantity.

(b) Determine the surplus or shortage that would exist if the price were $60.

Q13: Explain why the demand curve for a competitive firm is horizontal.

Q14: The marginal cost of a firm under perfect competition is given by the equation MC = 2Q_F - 20. The market price is $50 per unit. Determine the firm's profit-maximizing level of output. Write down the equation for the firm's supply curve.

Q15: For a perfectly competitive firm, long-run average cost is: LAC = 300 - 20Q_F + 0.5QF², where Q_F denotes the firm's output. Determine the firm's long-run profit-maximizing output and price.

Q16: In a perfectly competitive market, long-run average cost and long-run marginal cost are constant and equal: LAC = LMC = $8 for a typical firm. However, one of the firms discovers a technological innovation lowering its average cost and marginal cost to $7. How will this affect the equilibrium price? If all firms can take advantage of the innovation, what is the impact on the market price and industry profits?

Q17: A perfectly competitive market is described by the demand curve Q_D = 60 - 2P, and the supply curve Q_S = 5P - 10. A typical firm has the total cost equation: C = 16 + 2Q_F + QF².What is the equilibrium price and quantity in the market? Compute the firm's total revenue, total cost, and total profit.

Q18: A firm has the following cost function: C = 30 - 14Q + Q². Derive the firm's supply curve from the total cost function.

Q19: A small nation permits free trade in good X. At the good's free-trade price of $8, domestic firms supply 6 million units and imports account for 4 million units. Recently, the small country has erected trade barriers with the result that imports have fallen to zero, price has risen to $10, and domestic supply has increased to 8 million units. Calculate the change in consumer surplus and producer surplus resulting from the trade barrier. What is the deadweight loss?
