### Interest Rate and Capital Graph

#### Graph Description:

- **Axes:**
  - The horizontal axis represents **Capital (Billions of dollars)** ranging from 0 to 8.
  - The vertical axis represents the **Interest Rate (i.e., r) in percent**, ranging from 0 to 18.

- **Lines:**
  - **Demand Line (D):** This line is depicted in blue, running diagonally from the top left to the bottom right.
  - **Supply Lines (S1 and S2):**
    - **Supply Line S1:** Shown in gray, moving diagonally from the bottom left to the top right.
    - **Supply Line S2:** Shown in orange, placed parallel to S1 but positioned slightly below it.

- **Equilibrium Point:** Marked to the right of the graph, indicating where supply meets demand.

#### Questions:

1. **Interest Rate Volatility:**

   Which tend to be more volatile, short- or long-term interest rates?

   - ○ Short-term interest rates
   - ○ Long-term interest rates

2. **Real Rate of Interest Calculation:**

   If the inflation rate was 3.40% and the nominal interest rate was 5.60% over the last year, what was the real rate of interest over the last year? Disregard cross-product terms; that is, if averaging is required, use the arithmetic average. Round intermediate calculations to four decimal places.

   - ○ 1.87%
   - ○ 2.20%
   - ○ 2.53%
   - ○ 2.75%

The real risk-free rate (\(r^*\)) is 2.8% and is expected to remain constant. Inflation is expected to be 8% per year for each of the next two years and 7% thereafter.

The maturity risk premium (MRP) is determined from the formula: \(0.1(t - 1)%\), where \(t\) is the security’s maturity. The liquidity premium (LP) on all National Transmissions Corp.’s bonds is 0.55%. The following table shows the current relationship between bond ratings and default risk premiums (DRP):

| Rating        | Default Risk Premium |
|---------------|----------------------|
| U.S. Treasury | —                    |
| AAA           | 0.60%                |
| AA            | 0.80%                |
| A             | 1.05%                |
| BBB           | 1.45%                |

National Transmissions Corp. issues 14-year, AA-rated bonds. What is the yield on one of these bonds? Disregard cross-product terms; that is, if averaging is required, use the arithmetic average.

Choices:
- 5.45%
- 12.04%
- 11.29%
- 12.59%

Based on your understanding of the determinants of interest rates, if everything else remains the same, which of the following will be true?

- The yield on an AAA-rated bond will be higher than the yield on a BB-rated bond.
- Higher inflation expectations increase the nominal interest rate demanded by investors.

Expert Solution
Step 1: Define short and long term interest rate

"As per the policy, we can provide a solution to the first question only. Kindly raise the question for the solution to the other part."

A short term interest rates exists when the loan is taken for few years or months, quite similar to purchasing household appliances or electronic goods. However, a llong term interest rate is the loan taken for a many years or decades like purchasing a house or car.
