I have never understand this course before until now. This lectures from MIT are of great help to us studying economics.

[@kingrobert7246]

Does anyone know where the square root is derived from in all the production functions e.g. why is is sqrt of p x s not just p x s?

[@chappie3642]

It's probably to adhere to the law of diminishing marginal product of labor, If It were labor*Capital then the derivative of the quantity produced with respect to the labor would Just be the Capital, meaning that a given an increase of 1 in the labor provided the quantity of things produced increases by k regardless of how much labor Is already put in. On the other hand you can check for yourself that if the function Is F(L,K) = √(L*K) then the marginal product of labor Is √K/(2*√L) so as the labor increases so does the change in quantity produced when L increases (because of the √L in the denominator)

32:50 Land can be variable actually. Artificial Islands have already been created for many years. China for instance, has developed over 3200 acres of artificial land.

[@aarondesilva9578]

Land would be more of a long run variable than short run

[@gtawalkthrough336]

Isn't that land defined as 'natural resources' used in production? From this logic, artificial island which is man-made is not land.

When speaking about the second extreme case, i.e. non substitutable inputs, prof. Gruber states real examples are those where you need both products of a pair, such as, he says is the typical example, shoes...but to me those look like more as outputs, not inputs, i.e shoes are products...instead I found more convincing the example by the girl who says computer and programmer...has anyone an idea on that?

[@ishika775]

Yea . You are right . The example of right shoe and left shoe is generally taken in case of non substitutable indifference curves and not in case of isoquants. The example given by the girl is apt
