Economics of Production, Costs, and Profits

Vocabulary practice flashcards covering fundamental economic concepts of production functions, short-run vs. long-run capital, labor productivity, cost curves, and income statement structures.

Economic Profit

A measure of profit calculated by taking accounting profit and subtracting the expected rate of return (opportunity cost of capital), reflecting the total resources invested in the business.

Opportunity Cost of Capital

The expected rate of return or expected monetary gain that an investor anticipates earning on an alternative investment of equal risk.

Explicit Costs

Direct input costs that appear on a firm's financial statements and are utilized for income tax calculations.

Implicit Costs

The opportunity costs associated with an investment, representing the expected rate of return that should be earned from invested resources.

Fixed Inputs

Production inputs that exist in a predetermined, fixed quantity and are typically required prior to the commencement of production.

Variable Inputs

Production inputs whose quantities fluctuate directly with the level of output produced, such as labor, fuel, and raw materials.

Production Function

The mathematical or technological relationship determining how output is produced from a given set of inputs.

Total Product

The entire quantity of output generated by a firm as a function of the specific inputs employed.

Short Run

A production timeframe in which labor is variable but capital stock remains fixed and cannot be easily changed.

Long Run

A production timeframe sufficiently long for a firm to modify its capital stock and structural capacity.

Very Long Run

A extended period during which entirely new, transformative technologies are developed and integrated into production.

Average Productivity of Labor

The average output generated per unit of labor, calculated as total product divided by the quantity of labor ($\frac{Q}{L}$).

Marginal Product of Labor

The extra output generated from adding one additional unit of labor ($\frac{\Delta Q}{\Delta L}$).

Fixed Costs

Costs linked to fixed inputs that remain constant regardless of whether production output increases or decreases.

Variable Costs

Costs that change directly in response to variations in the quantity of variable inputs and output produced.

Total Cost

The complete cost of production, calculated by adding total fixed costs to total variable costs ($TC = FC + VC$).

Average Total Cost (ATC)

The total cost divided by the quantity produced ($\frac{TC}{Q}$), serving as the primary metric of production efficiency.

Average Fixed Cost (AFC)

The fixed cost per unit of output, calculated as fixed cost divided by quantity ($\frac{FC}{Q}$), which steadily declines as output rises.

Average Variable Cost (AVC)

The variable cost per unit of output, calculated by dividing total variable costs by the quantity produced ($\frac{VC}{Q}$).

Marginal Cost (MC)

The additional cost incurred to manufacture one extra unit of output ($\frac{\Delta TC}{\Delta Q}$).

Minimum Efficient Scale (MES)

The point corresponding to the minimum point of the average total cost curve, representing the level of maximum efficiency at the lowest per-unit cost.

Cost of Goods Sold (COGS)

An income statement line item representing the variable costs of production directly associated with variable inputs.

Gross Profit

The difference between total revenue and the cost of goods sold (variable costs), equivalent to producer surplus, which is used to cover fixed costs.

Accounting Profit

The profit remaining on a financial statement after deducting explicit variable costs, fixed costs, depreciation, interest, and taxes.
