In neoclassical economics, a firm is assumed to be an 'irrational agent' that wants to maximize total profit.

Total revenue is the sum of all costs incurred by a firm.

Marginal revenue (MR) is the additional revenue gained from selling an extra unit of product.

If marginal revenue (MR) is less than marginal cost (MC), the firm's total profit is maximized.

A firm should increase its output level until marginal revenue (MR) equals marginal cost (MC) to maximize total profit.

Firms always have reliable information to determine costs at all levels of production.

Profit maximization is only relevant in perfectly competitive markets.

Total profit is the difference between total revenue and total cost.

Increases in production that lead to greater marginal revenue than marginal cost indicate opportunities for additional profit.
