a. Explain how marginal revenue curves are derived from total revenue curves.

b. Explain why marginal revenue curves might slope downwards.

c. Explain why marginal revenue curves might be horizontal.

Expert Solution

a. Marginal revenue divides the change in total revenue by the change in the quantity sold.
Therefore marginal revenue is the slope of the total revenue curve.
Total revenue is the amount of sales of goods and services.
Marginal revenue is directly related to total revenue because it measures the change in revenue that results from a change in the amount of goods and services sold.
To calculate marginal revenue,divide the change in total revenue by the change in the quantity sold.
Therefore marginal revenue is the slope of total revenue curve.
Marginal revenue falls as the monopolist raises its out put.
The downward sloping market demand curve indicates that the new market price will be lower than before.

b. The downward sloping of marginal revenue curve implies that price a monopolist expects to receive will not remain constant while it increases its out put.

c. The marginal revenue curve for a perfectly competitive firm is horizontal due to the fact that it faces perfectly elastic demand at the market determined price.

Explain how marginal revenue product is derived. Why is the MRP curve also the firms' short-run the demand curve for labor? Explain why and how the demand curve for labor differs between firms operating in a competitive industry and an imperfectly competitive industry (i.e., monopoly).

14. Consider a monopoly facing the following demand, marginal revenue, total cost, and marginal cost curves: Demand curve: P = 12 – 0.002 Q Marginal revenue curve: MR = 12 – 0.004 Q Total cost curve: TC = 3Q +0.0005Q2 Marginal cost curve: MC = 3 + 0.001 Q a.

Define and explain the relationship between total revenue, average revenue, and marginal revenue for a monopolist....

Define and explain the relationship between total revenue, average revenue, and marginal revenue for a monopolist. What is monopoly profit? Should a monopolist produce quantities of product greater than that which would maximize profits?

Draw a graph for a monopoly with demand, marginal revenue, and marginal cost curves.

Assignment: Draw a graph for a monopoly with demand, marginal revenue, and marginal cost curves. Identify the profit-maximizing output level (Qm) and price (Pm). (Photos of your work are not accepted) Suppose the monopolist sells Qm units of output at the regular price and then puts the product on sale at a lower price, Ps. Show the new price and quantity. What happens to the firm’s profits? Does price discrimination lead to a more efficient or less efficient outcome? Why...
