A production function can be expressed in a functional form as the right side of = (,,, …,) where is the quantity of output and ,,, …, are the quantities of factor inputs (such as capital, labour, land or raw materials).
Wire-grid Cobb–Douglas production surface with isoquants A two-input Cobb–Douglas production function with isoquants. In economics and econometrics, the Cobb–Douglas production function is a particular functional form of the production function, widely used to represent the technological relationship between the amounts of two or more inputs (particularly physical capital and labor) and ...
The CES production function is a neoclassical production function that displays constant elasticity of substitution. In other words, the production technology has a constant percentage change in factor (e.g. labour and capital) proportions due to a percentage change in marginal rate of technical substitution.
The production functions are understood and formulated differently in growth accounting and management accounting. In growth accounting the production function is formulated as a function OUTPUT=F (INPUT), which formulation leads to maximize the average productivity ratio OUTPUT/INPUT.
At low production levels the AP L tends to increase as additional labor is added. The primary reason for the increase is specialization and division of labor. [6] At the point the AP L reaches its maximum value AP L equals the MP L. [7] Beyond this point the AP L falls. During the early stages of production MP L is greater than AP L.
Two input Leontief Production Function with isoquants. In economics, the Leontief production function or fixed proportions production function is a production function that implies the factors of production which will be used in fixed (technologically predetermined) proportions, as there is no substitutability between factors.
A firm's production function could exhibit different types of returns to scale in different ranges of output. Typically, there could be increasing returns at relatively low output levels, decreasing returns at relatively high output levels, and constant returns at some range of output levels between those extremes.
This is a list of production functions that have been used in the economics literature. Production functions are a key part of modelling national output and national income . For a much more extensive discussion of various types of production functions and their properties, their relationships and origin, see Chambers (1988) [ 1 ] and Sickles ...
