Question:
1. Suppose the marginal rate of return to capital invested in U.S. businesses Kb is rb = 20 − (2/3)Kb where rb is a percentage (that is, rb = 5 means a 5 percent rate of return)
and capital is measured in trillions of dollars. The marginal rate of return on housing investment is rh = 11 − (1/2)Kh.
The total amount of capital that can be invested in the United States is $25 trillion.
