Draw the following two graphs, one above the other: In the top graph, plot firm value on
the vertical axis and total debt on the horizontal axis. Use this graph to illustrate the value
of a firm under M & M without taxes, M & M with taxes, and the static theory of capital
structure. On the lower graph, plot the WACC on the vertical axis and the debt-equity ratio
on the horizontal axis. Use this second graph to illustrate the value of the firm’s WACC
under M & M without taxes, M & M with taxes, and the static theory. Briefly explain what
the two graphs reveal about firm value and its cost of capital under the three different
theories.
