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 (Percent) 7 6 4 3 2 National Saving (Billions of dollars) 45 40 35 30 25 20 Domestic Investment (Billions of dollars) 30 35 40 45 50 55 Net Capital Outflow (Billions of dollars) -15 -10 0 5 10 Given the information in the table above, use the blue points (circle symbol) to plot the demand for loanable 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.

### Understanding the Relationship Between Interest Rates and Economic Indicators

#### Table: Economic Indicators in a Hypothetical Open Economy

This table illustrates the association between real interest rates and various economic indicators, including national saving, domestic investment, and net capital outflow in a hypothetical economy using the U.S. dollar. The economy is assumed to be operating under a balanced government budget.

| Real Interest Rate (Percent) | National Saving (Billions of dollars) | Domestic Investment (Billions of dollars) | Net Capital Outflow (Billions of dollars) |
|------------------------------|--------------------------------------|------------------------------------------|------------------------------------------|

#### Graph: Market for Loanable Funds

- **Axis Labels**:
  - Vertical Axis: Real Interest Rate
  - Horizontal Axis: Quantity of Loanable Funds

- **Instructions for Plotting**:
  - **Demand Curve**: Use blue circle points to plot the demand for loanable funds.
  - **Supply Curve**: Use orange square points to plot the supply of loanable funds.
  - **Equilibrium**: Use a black cross point to indicate the market equilibrium.

This graph helps in visualizing how different interest rates affect the quantity of loanable funds available, thus illustrating economic dynamics in an open market.

### Understanding the Relationship Between Real Interest Rates and Net Capital Outflow

**Graph Overview:**
The graph illustrates the relationship between the real interest rate and net capital outflow. The x-axis represents the net capital outflow measured in billions of dollars, ranging from -20 to 20. The y-axis represents the real interest rate, ranging from 0 to 10.

**Plotting Points:**
- The green triangle symbol ("NCO") is used to plot the points representing the initial data relationship.
- The black "X" symbol marks the equilibrium net capital outflow (Eqm. NCO) at the determined real interest rate.

**Analysis Tasks:**
1. **Net Capital Outflow and Net Exports:**
   - The level of net capital outflow at equilibrium implies the economy's state is in need of identification (budget surplus or deficit).

2. **Government Budget Deficit Impact:**
   - When the government has a budget deficit, it leads to a change in the economy, affecting either national saving or domestic investment. Options to consider include:
     - National saving will decrease.
     - Domestic investment will decrease.

3. **Post-Deficit Equilibrium:**
   - After a budget deficit occurs, the new equilibrium real interest rate increases, impacting the foreign currency exchange market.

4. **Supply and Demand Curves:**
   - Use the green line (triangle symbol) to plot the new supply curve in the market.
   - Use the purple line (diamond symbol) to illustrate the updated demand curve after a budget deficit.

Through the use of the graph and further analysis, these steps aid in understanding the broader economic impacts of changes in net capital outflow and governmental fiscal behavior.
