Consider two competitive economies that have the same quantities of labor (L = 400) and capital (K = 400), and the same technology (A = 100). The economies of the countries are described by the following Cobb–Douglas production functions:

North Economy:Y =
A L
^0.
3
K
^0
.7

South Economy:Y = A L
^0
.7
K
^0
.3

In which economy is the marginal product of labor larger? Explain.
