QUESTION 1
A. The total cost function for a monopolist is given by TC = 44,000 + 180Q + 0.03Q² and the demand
function is P = 420 – 0.06Q per unit of output.
i.
What is the profit maximising level of output?
ii.
Calculate the profit maximizing price.
iii.
Calculate total profit at the profit maximising level of output.
Draw the cost curves for a typical firm. Explain how a competitive firm chooses the level of output that maximizes profit. At that level of output, show on your graph the firm’s total revenue and total cost.
Draw the demand curve, marginal revenue curve, average total cost curve, and marginal-cost curve for a monopolist. Show the profit-maximizing level of output, the profit-maximizing price, and the amount of profit.
Why the demand curve for a firm operating in monopolistic competition is more elastic compared to the firm operating as a monopoly. kindly solve all the parts.

- I will rate and like, thank you! Easy economics question. Create graph that includes: Demand curve, marginal cost, and marginal revenue. Identify the profit-maximizing quantity and price for this monopolist. To do this you will need to determine marginal revenue at each level of output. Choose output that satisfies the monopolist’s profit maximizing condition of MR = MC. Does this firm earn a profit? How much profit if they do?arrow_forwardhey how are you a)Draw the cost curves for a typical firm. Explain how a competitive firm chooses the level of output that maximizes profit.

- A monopolist firm faces a demand with constant elasticity of -1.3. It has a constant marginal cost of $18 per unit and sets a price to maximize profit. If marginal cost should increase by 20 percent, would the price charged also rise by 20 percent? A. Yes. Since the price elasticity of demand is constant, P = 1.3MC. Thus, if MC increases by 20 percent, price also increases by 20 percent. B. No. Since the demand curve is downward sloping, a 20 percent increase in MC will cause the price to increase by more than 20 percent. OC. Yes. Since the price elasticity of demand is constant, P = 4.33MC. Thus, if MC increases by 20 percent, price also increases by 20 percent. OD. No. Since the demand curve is downward sloping, a 20 percent increase in MC will cause the price to increase by less than 20 percent.arrow_forwardCurrently, a monopolist's profit-maximizing output is 400 units per week and it sells its output at a price of S60 per unit.
