问题如下：
When total factor productivity increases, the capital-to-labor ratio will most likely:
选项：
A.decrease
B.remain unchanged
C.increase
解释：
A Incorrect because increasing total factor productivity (TFP) will result in an increase in the capital-to-labor ratio, which is also known as capital deepening.
B Incorrect because increasing total factor productivity (TFP) will result in an increase in the capital-to-labor ratio, which is also known as capital deepening.
C Correct
because increasing total factor productivity (TFP) (reflecting the general
level of productivity or technology in the economy) will result in an increase
in the capital-to-labor ratio, which is also known as capital deepening. Note
that once technological progress (TFP growth) is introduced, the
capital-to-labor ratio will have to keep increasing just to keep the marginal
productivity of capital equal to its marginal cost. But the point remains: Once
that equality is attained, companies will not increase the capital-to-labor
ratio faster than is necessary to maintain that equality.
老师，请问从公式与=T（k/L）^a看出，T是total factor productivity，k/L是capital-to-labor ratio，如果T increase，会对y 有所提高，但应该不会对capital-to-labor ratio有影响才对啊
