Examine the graph above. Suppose that government increases its spending, shifting the aggregate expenditure line upwards. GDP increases from GDP1 to GDP2, and this amount is $550 billion. If the MPC is 0.8, calculate the difference between the points N and L to find out by how much the government spending changed.
The desired aggregate expenditure function of an economy is illustrated in the graph to the right. The
dashed line, Y*, shows the potential level of national income in this economy. The marginal propensity
to spend is 0.75.
Use the point drawing tool to plot and label the equilibrium level of income.
Carefully follow the instructions above, and only draw the required object.
