3. Effects of a government budget deficit

Consider a hypothetical open economy. The following table presents data on the relationship between various real interest rates and national saving, domestic investment, and net capital outflow in this economy, where the currency is the U.S. dollar. Assume that the economy is currently experiencing 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.

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    , which leads to    loanable funds.
 
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.
