Briefly explain the nature of a perfectly competitive firm. Briefly discuss the effects of new entrants into a perfectly competitive market on existing firms that have profits in the short run.
A perfectly competitive firm is a price taker, which means that it must accept the prices at which its sell goods and the prices at which it purchases inputs as determined in the market. Firms in a highly competitive market may earn profits in the short run, but the entry of new firms or the expansion of existing firms means that such profits will not persist in the long run.
An _________________ is calculated by subtracting the firm's costs from its total revenues, _______________________________ .
A. accounting profit; excluding opportunity cost
If a firm is producing so that the point chosen along the production possibility frontier is socially preferred, then that firm is said to have reached its
A. allocative efficiency
If a competitive firm experiences a shift in costs of production that decreases marginal costs at all levels of output,
A. expanding output levels at any given price will be profitable.
______________________ refers to the additional revenue gained from selling one more unit.

In a free market economy, firms operating in a perfectly competitive industry are said to have only one major choice to make. Which of the following correctly sets out that choice?
A. what quantity to produce
Briefly explain what is meant by: 1) account profit; 2) economic profit; and 3) zero economic profit.
Accounting profit is measured by taking total revenues and subtracting expenditures. Economic profit is measured after taking total revenue, subtracting all expenditures, and also subtracting the opportunity cost of financial capital. Thus, zero economic profit actually means a normal accounting rate of profit.
Briefly describe what the effect of producing a greater quantity of products will be in relation to a perfectly competitive firm.
As a perfectly competitive firm produces a greater quantity of output, its total revenue steadily increases at a constant rate determined by the given market price.

Why would a profit-seeking firm need to tailor its decisions about the quantity of labor inputs that it purchases?
D. to produce the profit-maximizing quantity of output at the lowest possible average cost
Briefly explain how the zero profit point and the shutdown point for a firm operating in a perfectly competitive market are each determined.
For a firm operating in a perfectly competitive market, the point where the marginal cost curve crosses the average cost curve, at the minimum of the average cost curve, is called the zero profit point. The point where that firm's marginal cost curve crosses the average variable cost curve is called the shutdown point.
Briefly explain the relationship between market price and a firm's profitability in perfectly competitive market.
If the market price faced by a perfectly competitive firm is above average cost at the profit-maximizing quantity of output, then the firm is making profits. If the market price is below average cost at the profit-maximizing quantity of output, then the firm is making losses. If the market price is at average cost, at the profit-maximizing level of output, then the firm is making zero profits.
Briefly discuss physical capital investment and long-run average cost in relation to a perfectly competitive market.
In a perfectly competitive market, firms seek out the combination of variable inputs like labor and fixed inputs like physical capital investment inputs that will allow them to produce at the minimum of the long-run average cost curve. If a firm does not produce at the lowest possible average cost, then firms with a lower cost of production will be able to sell at a lower price. Thus, the pressure of competition between firms will shape both the specific kinds of machinery and equipment and the overall quantity of investment in physical capital.
Briefly contrast how firms in a perfectly competitive market will respond to long-run profits and losses. Include an explanation of each response affects the price level.
In the long run, firms will respond to profits through a process of entry, where existing firms expand output and new firms enter the market. Conversely, firms will react to losses in the long run through a process of exit, in which existing firms reduce output or cease production altogether. Through the process of entry in response to profits and exit in response to losses, the price level in a perfectly competitive market will move toward the zero-profit point where the marginal cost curve crosses the average cost curve, at the minimum of the average cost curve.
Briefly contrast when losses will be the smallest for a perfectly competitive firm based on total revenues with when losses for such a firm will be smallest based on marginal revenue.
Losses will be smallest for a completely competitive firm at the quantity of output where total revenues exceed total costs by the greatest amount, or where total revenues fall short of total costs by the smallest amount. Alternatively, losses will be the smallest where marginal revenue, which is price for a perfectly competitive firm, is equal to marginal cost.
Briefly explain what a market will show if perfectly competitive firms produce at the minimum of the long-run average cost curve and explain why this happens. Briefly explain what the market will illustrate when perfectly competitive firms produce at the quantity where P = MC and explain why this happens.
When perfectly competitive firms produce at the minimum of the long-run average cost curve, the market will show productive efficiency, since all the firm's are producing at the lowest possible average cost. When perfectly competitive firms produce at the quantity where P = MC, the market will illustrate allocative efficiency, since each good is being produced up to the quantity where the amount that the good benefits society, which is measured by the price people are willing to pay, is equal to the cost to society, which is measured by the marginal cost of production.
