Question

A purely competitive firm whose goal is to maximize profit will choose to produce the amount of output at which: a. TR and TC are equal. b. TR exceeds TC by as much as possible. c. TC exceeds TR by as much as possible. d. none of the above.

Short answer

b. TR exceeds TC by as much as possible.

Step-by-step solution

Understand the Objective

The problem asks for the production point of a firm that seeks to maximize profit. Remember, profit is the difference between total revenue (TR) and total cost (TC). Thus, the firm would aim for the point where this difference is greatest.

Evaluate the Options

Let's break down each option: a. If TR and TC are equal, the profit is zero since TR - TC = 0. b. TR exceeds TC by as much as possible, which means profit is maximized, since profit = TR - TC. c. TC exceeds TR by as much as possible, which would indicate a loss since profit = TR - TC and would be negative.

Determine the Correct Answer

Given the objective of maximizing profit, which is achieved when the difference between TR and TC is maximized, the choice should be the scenario where TR exceeds TC by the largest possible amount.

Key concepts

Total Revenue

Total Revenue (TR) is a fundamental concept in economics that refers to the total income a firm receives from selling its goods or services. It's calculated by multiplying the price per unit of the product by the quantity of the product sold. For example, if a firm sells 100 units of a product at a price of $5 each, the total revenue would be \( TR = 100 \times 5 = 500 \).

Total Revenue plays a critical role in determining a firm's financial health and its strategy in the marketplace. By understanding how total revenue changes as they sell more or less of their product, firms can better plan their production and sales strategies. It's the starting point for assessing a firm's ability to cover its costs and eventually earn a profit.

Total Cost

Total Cost (TC) encompasses all the expenses a firm incurs to produce and sell its goods or services. This includes both fixed costs, which do not vary with output (like rent and salaries), and variable costs, which change with the production level (like materials and utility expenses).

The formula for total cost is the sum of fixed costs and variable costs: \( TC = ext{Fixed Costs} + ext{Variable Costs} \). This calculation is essential in understanding a firm's financial situation since it directly impacts the bottom line known as profit (calculated as TR minus TC).

Understanding total cost helps firms determine break-even points and pricing strategies. The goal is often to produce outputs such that the total revenue exceeds this total cost as efficiently as possible.

Pure Competition

Pure Competition is a market structure characterized by a large number of small firms, all producing identical products, which makes every firm a price taker. In such a market, no single firm has the power to influence prices, and the market dictates the price based on the collective supply and demand.

In pure competition, firms focus on optimizing their operations to maximize efficiency. Since products are homogeneous, the only way to stand out is by being more cost-effective. Entry and exit in the market are relatively easy, fostering an environment of constant innovation and improvement.

This market type is idealized and serves as a benchmark. It provides insights into the outcomes of unregulated, free-market economies and helps economists understand the principles of supply and demand at their most basic level.

Firm Objective

The primary objective of a firm, particularly in a purely competitive market, is often to maximize profit. Profit is the difference between what a firm earns (Total Revenue) and what it spends (Total Cost).

A firm achieves profit maximization by producing the amount of output where this difference—TR minus TC—is the greatest. This involves producing up to the point where the additional cost of producing one more unit, known as marginal cost, is equal to the revenue gained from selling that unit, called marginal revenue.

By focusing on profit maximization, firms can sustain their operations and encourage growth. It also allows them to survive competition, make investments in innovation, and ultimately contribute to economic growth more broadly by allocating resources efficiently.
