Question

If consumption is C=100+0.75Yd

Taxes is T=50+0.5Y

Export is X=200

Import is M=50+0.25Y

Government spending is G=150

Investment is I=200

.Use the multiplier applicable to export,to explain how a100–billion decline in demand for export could affect the economy’s:


(i)

GDP/income

 

Answer

An export multiplier is a multiplier that is applicable to export. The effect of a decline in demand by 100 billion on GDP/income will be computed by the export multiplier. Thus,

Export Multiplier=1/(1−MPC+M)

=1/(1-0.75+0.5)=1.33

The export multiplier shows that the GDP/income will be decreased by 1.33 billion with the decline in the 100-billion decline in the demand.

 please show how you get M=0.5
