The amount of memory needed for the input data. The amount of memory needed for any output data. Some algorithms, such as sorting, often rearrange the input data and do not need any additional space for output data. This property is referred to as "in-place" operation. The amount of memory needed as working space during the calculation.
Productivity is the efficiency of production of goods or services expressed by some measure. Measurements of productivity are often expressed as a ratio of an aggregate output to a single input or an aggregate input used in a production process, i.e. output per unit of input, typically over a specific period of time. [1]
Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula r=P/C, where P is the amount of useful output ("product") produced per the amount C ("cost") of resources consumed.
The economic value of physical outputs minus the economic value of physical inputs is the income generated by the production process. By keeping the prices fixed between two periods under review we get the income change generated by a change of the production function.
In economics, output elasticity is the percentage change of output (GDP or production of a single firm) divided by the percentage change of an input. It is sometimes called partial output elasticity to clarify that it refers to the change of only one input. [1] As with every elasticity, this measure is defined locally, i.e. defined at a point.
A curve of output against input. The areas of increasing, diminishing and negative returns are identified at points along the curve. There is also a point of maximum yield which is the point on the curve where producing another unit of output becomes inefficient and unproductive.
TFP is calculated by dividing output by the weighted geometric average of labour and capital input, with the standard weighting of 0.7 for labour and 0.3 for capital. [3] Total factor productivity is a measure of productive efficiency in that it measures how much output can be produced from a certain amount of inputs.
In microeconomics, economies of scale are the cost advantages that enterprises obtain due to their scale of operation, and are typically measured by the amount of output produced per unit of cost (production cost) . A decrease in cost per unit of output enables an increase in scale that is, increased production with lowered cost. [1]
