Large number of buyers and sellers ensures no single entity can influence market price.

Rent for factory space remains constant regardless of production levels.

Cost-benefit analysis evaluates whether benefits of a decision outweigh its costs.

In a monopoly, a single seller has significant control over the market price.

Explicit costs involve direct monetary payments, whereas implicit costs represent opportunity costs.

Marginal cost reflects the cost increase from producing an additional unit of output.

Normal profit is earned when total revenue equals total cost, including opportunity costs.

Adding more of a variable input to fixed inputs leads to diminishing returns per additional unit.

Firms in monopolistic competition have some control over pricing due to product differentiation.

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

At the minimum AVC, marginal cost equals AVC.

Total revenue decreases as price elasticity of demand increases, and vice versa.

Natural monopolies exist due to high barriers to entry, such as economies of scale.

Profit maximization occurs at the point where marginal cost equals marginal revenue.

A perfectly elastic demand curve is horizontal, indicating any quantity can be sold at the same price.
