Why do we think about the interest rate as the "price" of capital?
◦ Because firms use financial capital to purchase physical capital and the interest rate is the "price" of financial capital.
◦ Because the interest rate determines the equilibrium level of investment demand.
◦ Because the interest rate represents the value the firm avoids paying to lenders by purchasing the capital instead.
◦ Because the interest rate determines the MRP of the capital, which determines its price.
◦ Because the interest rate is the amount the firm earns by purchasing the capital.
