This graph shows demand and supply functions for a hypothetical one-year corporation bond. The vertical axis measures the interest rate on this bond. The face value of this bond is F = $11,448.00. Currently, the market is in equilibrium. Suppose that an economic expansion starts and business firms decide to borrow more than before to invest in plants and equipment. In particular, they now want (willing and able) to borrow $40 million more than before. At the same time, as households' incomes increase, they want to invest in bonds. So demand for these bonds by households increases by $20 million. All else the same, these two events will cause the equilibrium interest rate to change to percent
