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. Real Interest Rate National Saving Domestic Investment Net Capital Outflow (Percent) (Billions of dollars) (Billions of dollars) (Billions of dollars) 7 55 30 -15 6 50 4O - 10 5 45 50 -5 4 40 60 0 3 35 7O 5 2 30 80 10 Given the information in the table above, use the blue points (circle symbol) to plot the demand for loanabie funds. Next, use the orange points (square symbol) to plot the supply of loanable funds. Finally, use the black point (cross symbol) to indicate the equilibrium in this market. /' , K21" Market for Loanable Funds 10 - Demand El 6 __ Supply '1' Equilibrium REAL INTEREST RATE 0 1IIIlI 0 20 40 60 80 100 QUANTITY OF LOANABLE FUNDS 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.

Now, suppose the government is experiencing a budget deficit. This means that V , which leads to V loanable funds. After the budget decit 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. ?
