In economics, a cost curve is a graph of the costs of production as a function of total quantity produced. In a free market economy, productively efficient firms optimize their production process by minimizing cost consistent with each possible level of production, and the result is a cost curve. Profit-maximizing firms use cost curves to decide output quantities. There are various types of ...
Short-run cost curves. In economics, average variable cost (AVC) is a firm's variable costs (VC; labour, electricity, etc.) divided by the quantity of output produced (Q): Average variable cost plus average fixed cost equals average total cost (ATC): A firm would choose to shut down if the price of its output is below average variable cost at ...
In the simplest case, where cost is linear in output, the equation for the total semi-variable cost is as follows: [6] where is the total cost, is the fixed cost, is the variable cost per unit, and is the number of units (i.e. the output produced).
In economics, total cost (TC) is the minimum financial cost of producing some quantity of output. This is the total economic cost of production and is made up of variable cost, which varies according to the quantity of a good produced and includes inputs such as labor and raw materials, plus fixed cost, which is independent of the quantity of a ...
Average cost. In economics, average cost (AC) or unit cost is equal to total cost (TC) divided by the number of units of a good produced (the output Q): Average cost is an important factor in determining how businesses will choose to price their products.
Average fixed cost is the fixed cost per unit of output. As the total number of units of the good produced increases, the average fixed cost decreases because the same amount of fixed costs is being spread over a larger number of units of output. Average variable cost plus average fixed cost equals average total cost:
The long run shutdown point for a competitive firm is the output level at the minimum of the average total cost curve. Assume that a firm's total cost function is the same as in the above example.
Graph of total, average, and marginal product. In economics, a production function gives the technological relation between quantities of physical inputs and quantities of output of goods. The production function is one of the key concepts of mainstream neoclassical theories, used to define marginal product and to distinguish allocative ...
