Profit and Cost Analysis in Microeconomics Quiz

Explicit costs are tangible, out-of-pocket expenses incurred by a firm in conducting its business operations.

Total revenue is calculated by multiplying the price per unit by the quantity of units sold.

Average variable cost is the total variable cost divided by the quantity of output produced.

Marginal revenue is the change in total revenue resulting from selling one additional unit of output.

Opportunity cost represents the benefits an individual or business forgoes when choosing one alternative over another.

Marginal cost represents the change in total cost when one additional unit of output is produced.

In a perfectly competitive market, products are identical or homogeneous, with no differentiation.

When average total cost is decreasing, marginal cost is less than average total cost.

If marginal cost is less than average total cost, producing additional units adds more to revenue than to costs, increasing profit.

Monopolies often produce unique or differentiated products, unlike the homogeneity of perfectly competitive markets.

Economies of scale occur when a firm's average total cost decreases as it increases production.

Economic profit accounts for both explicit costs (like rent) and implicit costs (like opportunity costs).

In perfect competition, profit is maximized when marginal cost equals marginal revenue.

Total revenue reaches its maximum point when the price elasticity of demand is unitary elastic, indicating that any price change has no effect on total revenue.

Economic profit considers both explicit and implicit costs, while accounting profit only considers explicit costs.

The shutdown point occurs when a firm cannot cover its variable costs with its total revenue.
