| If the Cobb-Douglas production function is **Q(L,K) = A L<sup>β</sup>K<sup>α</sup>**, the output elasticity with respect to labor (L) is β and the output elasticity with respect to capital (K) is α. | If the Cobb-Douglas production function is **Q(L,K) = A L<sup>β</sup>K<sup>α</sup>**, the output elasticity with respect to labor (L) is β and the output elasticity with respect to capital (K) is α. | ||
