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 ...
Let's say the utility function is the Cobb-Douglas function (,) =, which has the Marshallian demand functions [2] (,) = (,) =,where is the consumer's income. The indirect utility function (,,) is found by replacing the quantities in the utility function with the demand functions thus:
As its name suggests, the CES production function exhibits constant elasticity of substitution between capital and labor. Leontief, linear and Cobb–Douglas functions are special cases of the CES production function. That is, If approaches 1, we have a linear or perfect substitutes function;
This is a list of production functions that have been used in the economics literature. ... Cobb–Douglas production function (or imperfect complements)
The equation below (in Cobb–Douglas form) is often used to represent total output (Y) as a function of total-factor productivity (A), capital input (K), labour input (L), and the two inputs' respective shares of output (α and β are the share of contribution for K and L respectively). As usual for equations of this form, an increase in ...
An example of a utility function that generates indifference curves of this kind is the Cobb–Douglas function (,) =,. The negative slope of the indifference curve incorporates the willingness of the consumer to make trade offs. [9]
Other forms include the constant elasticity of substitution production function (CES), which is a generalized form of the Cobb–Douglas function, and the quadratic production function. The best form of the equation to use and the values of the parameters ( a 0 , … , a n {\displaystyle a_{0},\dots ,a_{n}} ) vary from company to company and ...
These functions are commonly used as examples in consumer theory. The functions are ordinal utility functions, which means that their properties are invariant under positive monotone transformation. For example, the Cobb–Douglas function could also be written as: + . Such functions only become interesting when there are two or more ...
