f there a \$2billion increase in government spending, other things being equal, what would be the resulting change in aggregate demand, and how much of the change would a change in consumption, if the MPC were the following:

1/3?

1/2?

2/3?

3/4?

4/5?

Government expenditure multiplier is given by = [ 1/(1-MPC)] , note that there is a \$2 billion increase in government spending.

1.) If MPC = 1/3

Multiplier = [1/(1-1/3)] = 1.5

Thus resulting change in aggregate demand = (1.5)( \$2 billion ) = \$3 billion

2.) If MPC = 1/2

Multiplier = [1/(1-1/2)] = 2

Thus resulting change in aggregate demand = (2)( \$2 billion ) = \$4 billion

3.) if MPC = 2/3

Multiplier = [1/(1-2/3)] = 3

Thus resulting change in aggregate demand = (3)( \$2 billion ) = \$6 billion

4.) if MPC = 3/4

Multiplier = [1/(1-3/4)] = 4

Thus resulting change in aggregate demand = (4)( \$2 billion ) = \$8 billion

5.) if MPC = 4/5

Multiplier = [1/(1-4/5)] = 5

Thus resulting change in aggregate demand = (5)( \$2 billion ) = \$10 billion
