Find out the value of the multiplier if the MPC is zero?

If consumers decide to increase saving, then C decreases, r decreases, I increases, and Y:

Consider a hypothetical economy in which households spend $0.50 of each additional dollar they earn and save the remaining $0.50. The following graph shows the economy's initial aggregate demand curve (AD1). Suppose the government increases its purchases by $2 billion. Use the green line (triangle symbol) on the following graph to show the aggregate demand curve (AD2) after the multiplier effect takes place. Hint: Be sure the new aggregate demand curve (AD2) is parallel to AD1. You can see the slope of AD1 by selecting it on the following graph. 114 152 110 100 100 104 102 150 100 102 104 108 108 110 112 114 110 OUTPUT( 30 41 The following graph shows the money market in equilibrium at an interest rate of 1.5% and a quantity of money equal to $45 billion.
