The Fisher Effect is used to relate the nominal interest rate, the real interest rate, and the inflation rate. The formula is:

$(1 + \text{Nominal Rate}) = (1 + \text{Real Rate}) \times (1 + \text{Inflation Rate})$

Given:

• Real Rate = 9.5% or 0.095
• Inflation Rate = 4% or 0.04

Now, plug the values into the formula:

$(1 + \text{Nominal Rate}) = (1 + 0.095) \times (1 + 0.04)$

$(1 + \text{Nominal Rate}) = 1.095 \times 1.04$

$(1 + \text{Nominal Rate}) = 1.1398$

So:

$\text{Nominal Rate} = 1.1398 - 1 = 0.1398 = 13.98\%$

The closest answer to this result is 13.88%.

The correct answer is 13.88%.

Here are 5 related questions to consider:

1. How does the Fisher Effect apply in cases of negative inflation rates (deflation)?
2. What happens to the nominal rate if inflation significantly increases while the real rate stays constant?
3. Can the Fisher Effect be used for short-term interest rates, and why?
4. How would the nominal rate change if the real rate was instead 8% with the same inflation rate?
5. What are some real-world examples where the Fisher Effect is useful for investors?

Tip: Remember, nominal rates incorporate both the real rate and inflation expectations, so they tend to rise as inflation increases!
