Figure 34-2. On the left-hand graph, MS represents the supply of money and MD represents the demand for money; on the right-hand graph, AD represents aggregate demand. The usual quantities are measured along the axes of both graphs.

-Refer to Figure 34-2. A decrease in Y from Y1 to Y2 is explained as follows:
A) The Federal Reserve increases the money supply, causing the money-demand curve to shift from MD1 to MD2; this shift of MD causes r to increase from r1 to r2; and this increase in r causes Y to decrease from Y1 to Y2.
B) An increase in P from P1 to P2 causes the money-demand curve to shift from MD1 to MD2; this shift of MD causes r to increase from r1 to r2; and this increase in r causes Y to decrease from Y1 to Y2.
C) A decrease in P from P2 to P1 causes the money-demand curve to shift from MD1 to MD2; this shift of MD causes r to increase from r1 to r2; and this increase in r causes Y to decrease from Y1 to Y2.
D) An increase in the price level causes the money-demand curve to shift from MD2 to MD1; this shift of MD causes r to decrease from r2 to r1; and this decrease in r causes Y to decrease from Y1 to Y2.

An increase in the price level (P) leads to a higher demand for money, shifting the money-demand curve from MD1 to MD2. This shift causes the interest rate (r) to rise from r1 to r2, which in turn reduces the level of output (Y) from Y1 to Y2.
