Examples include raw materials, direct labor, Economies of Scale: and utilities. Economies of scale occur when the Total Cost (TC): average cost of production decreases as the scale of production increases. The sum of fixed and variable costs. It This is often associated with increased represents the overall cost of efficiency in large-scale operations. producing a specific quantity of goods or services. Technology and Innovation: Average Cost (AC): Technological advancements and innovations can significantly impact The per-unit cost of production, the production process, leading to calculated by dividing total cost by increased efficiency, reduced costs, the quantity of output. It includes and the development of new products. average fixed cost and average variable cost. Marginal Cost (MC): Production Costs The additional cost incurred by Production cost refers to the expenses producing one more unit of a good or incurred by a firm or producer in the process service. It is calculated by the change of manufacturing goods or providing in total cost divided by the change in services.

In production, it can be the potential Fixed Costs: revenue or benefits lost by choosing one production option over another. Costs that do not vary with the level of production. These costs exist even Sunk Costs: if production is zero. Examples include rent, insurance, and salaries of Costs that have already been incurred permanent staff. and cannot be recovered.

Common cost Isoquants (short for "equal quantity") curves include: are graphical representations used in ○ Average Total Cost (ATC) production theory to show all the Curve possible combinations of inputs ○ Marginal Cost (MC) Curve (usually labor and capital) that result ○ Average Variable Cost (AVC) in the same level of output.

Convexity of Isoquants: TC / Quantity Produced. ○ Isoquants are convex to the Marginal Cost (MC): The cost of origin, reflecting the producing an extra unit of output. diminishing marginal rate of technical substitution (MRTS). 3. MRTS (Marginal Rate of Technical Substitution): ○ MRTS measures the rate at which one input can be reduced while increasing the other input to maintain the same output level. It is the slope of the isoquant. 4. Higher Isoquants: ○ Represent higher levels of output. Moving to a higher  isoquant indicates an increase levels. Useful for visualizing in production. cost implications of different input combinations. 4. Optimal Input Combination: ○ The point where an isocost line is tangent to an isoquant represents the optimal combination of inputs for a given level of output. At this point, MRTS equals the input price ratio (w/r). 5. Expansion Path: ○ Connecting optimal points on isocost lines for various levels Isocost Lines of output creates the expansion path. It shows how the optimal Definition: input combination changes with increased production. An isocost line (equal cost) shows all possible combinations of inputs (labor and capital) that a firm can purchase for a given total cost.
