Figure 21-2. 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 21-2. 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.

Question

Quizplus · Accepted Answer

An increase in the price level (P) increases the demand for money, shifting the money-demand curve rightward from MD1 to MD2. This raises the interest rate (r), which in turn reduces aggregate output (Y) from Y1 to Y2.
