[[Cobb-Douglas production function]]: Y&nbsp;=&nbsp;A&nbsp;×&nbsp;C<sup>a</sup>&nbsp;×&nbsp;L<sup>b</sup>, where Y stands for yield, C for capital, L for labour, and A, a and b are constants that can be interpreted as A for technology level and a and b for the production elasticities.

The Cobb-Douglas production function

The Cobb-Douglas function has the form:

Y = A. Lα . Cβ,

where

Y = output,  C = capital input, L = labour input,
and A, α and β are constants determined by the technology employed.

If α = β = 1, the function represents constant returns to scale,

If α + β < 1, it represents diminishing returns to scale, and,

If α + β > 1, it represents increasing returns to scale.


It can be shown that, in a perfectly competitive economy, α is labour's share of the value of output, and β is capital's share.
