3. Effects of a government budget deficit
Suppose a hypothetical open economy uses the U.S. dollar as currency. The table below presents data describing the relationship between different
real interest rates and this economy's levels of national saving, domestic investment, and net capital outflow. Assume that the economy is currently
operating under a balanced government budget.

On the following graph, plot the relationship between the real interest rate and net capital outflow by using the green points (triangle symbol) to plot
the points from the initial data table. Then use the black point (X symbol) to indicate the level of net capital outflow at the equilibrium real interest
rate you derived in the previous graph.

Effects of a Budget Deficit
Because of the relationship between net capital outflow and net exports, the level of net capital outflow at the equilibrium real Interest rate implies
that the economy is experiencing
Now, suppose the government is experiencing a budget deficit. This means that

Market for Foreign-Currency Exchange
After the budget deficit occurs, suppose the new equilibrium real interest rate is 6%. The following graph shows the demand curve in the foreign-
currency exchange market.
Use the green line (triangle symbol) to show the supply curve in this market before the budget deficit. Then use the purple line (diamond symbol) to
show the supply curve after the budget deficit.
