### more macro

Justin, Heather, and I stayed after micro to keep working on this ridiculous assignment, anyways justin went and asked zimmerman about #2 using the math appendix to justify the investment function and zimmerman said that just taking the partial derivatives of i is not enough. Apparently we have to show this is a reasonable equation given the results from the appendix and keep in mind that the equation given is in log form and provides elasticities. Anyone have any ideas on what to do differently?
