The Original Cobb-Douglas Function Was Given As $\mathrm { Q } = \alpha \mathrm { L } ^ { \rho } \mathrm { L } ^ { 1 - \rho }$

Multiple Choice

The original Cobb-Douglas function was given as $\mathrm { Q } = \alpha \mathrm { L } ^ { \rho } \mathrm { L } ^ { 1 - \rho }$ .It was subsequently rewritten as $\mathrm { Q } = \alpha \mathrm { L } ^ { \rho 1 } \mathrm {~K} ^ { \rho2}$ .What benefit was derived in the revision?

A) the function becomes a non-linear relationship so it would fit to production curves having an "S" shape
B) returns to scale can be shown in the revision
C) returns to scale become constant
D) a and b only
E) a,b,and c
