Three graphs depict the money market, the investment market, and the product market side by side. Panel A, the money market, has interest rate on the y-axis and money on the x-axis, and plots a downward-sloping money demand curve M D 1 and two vertical money supply curves M S 1 and M S 2. M S 1 is to the left of M S 2. A horizontal dashed line connects the y-axis to the point where M S 1 intersects M D 1. This is labeled lower case i 1 on the y-axis. A horizontal dashed line connects the y-axis to the point where M S 2 intersects M D 1. This is labeled lower case i 2 on the y-axis. Panel B, the investment market, has interest rate on the y-axis and investment on the x-axis and plots a downward sloping investment curve labeled capital I. The horizontal dashed lines continue from Panel A, and depict lower case i 1 and lower case i 2 on the y-axis, and continue until they meet the investment curve. Where lower case i 1 meets the investment curve, a vertical dashed line drops to the x-axis and is labeled capital
