Updated profit max slides?

[Paul Kadletz]

I am curious as to why he updated the profit max slides and switched the positions of L and K. Making the first order condition MPk=r divided by MPl=w. This is the complete opposite of the problems that we have been practicing. Should we be expected to make this switch when it comes to problems on the final?

Looks to me it's MPk/MPl = r/w, which is the same thing as MPl/MPk = w/r, which is what we've been doing. Both sides have been inverted so it's consistent and the answer would still be the same.

Hi,

The professor stated that they could use any number of variables for Labor and Capital (factor 1 and factor 2, cooks and grills, etc). Just remember that it is MP1/MP2 = P1/P2 (the first variable divided by the second)
