Question
10. Extension of the Cobb-Douglas Production Function-The Cobb-Douglas produc-
tion function (Equation 7.16) can be shown to be a special case of a larger class of
linear homogeneous production functions having the following mathematical
form:"
Q = y[@K* + (1 – a)L°]W/P
where y is an efficiency parameter that shows the output resulting from given
quantities of inputs; a is a distribution parameter (0 sas 1) that indicates the
division of factor income between capital and labor; p is a substitution parameter
that is a measure of substitutability of capital for labor (or vice versa) in the pro-
duction process; and v is a scale parameter (v > 0) that indicates the type of re-
turns to scale (increasing, constant, or decreasing). Show that when v = 1, this
function exhibits constant returns to scale. [Hint: Increase capital K and labor L
each by a factor of A, or K* = (A)K and L* = (1)L, and show that output Q also
increases by a factor of A, or Q* = (A)(Q).]
