The monopolist faces a demand curve given by D(p)=10 p^-3. Its cost function is c(y)=2 y . What

step 1 in this problem let c y is equal to y square is same as cq is equal to q square i just replace y

Key Concepts

Monopolist Profit Maximization

This concept refers to the process by which a monopolist chooses the output level and corresponding price that maximizes its profit. The monopolist does not take market prices as given but rather influences the price by adjusting output. The decision is typically reached by equating marginal revenue and marginal cost, ensuring that any additional unit produced does not reduce overall profit.

Demand Curve

A demand curve represents the relationship between the price of a product and the quantity demanded by consumers. It is fundamental in economic analysis as it determines how price changes will affect sales. For a monopolist, the structure of the demand curve is crucial because it not only influences total revenue but also shapes the form of marginal revenue when output is varied.

Marginal Revenue

Marginal revenue is the additional revenue that a firm earns by selling one more unit of output. In the context of monopoly pricing, marginal revenue is derived from the total revenue function and is generally less than the price because selling extra units often requires lowering the price for all units sold. The concept is critical because the profit-maximizing condition is found where marginal revenue equals marginal cost.

Marginal Cost

Marginal cost is the additional cost incurred when producing one more unit of output. In the analysis of monopolies, it is important to determine the point where marginal cost equals marginal revenue for profit maximization. Marginal cost provides insight into how production costs change with output and is a key factor in determining the optimal production level.

Equating Marginal Revenue and Marginal Cost

This optimization condition is the rule that ensures maximum profit for a monopolist. By setting marginal revenue equal to marginal cost, the firm identifies the level of production beyond which additional output would not contribute positively to profit. This balance point is fundamental in both theoretical and applied economics for understanding firm behavior in markets with a single seller.
