Question

Treasury bills are currently paying 8 percent and the inflation rate is 2.8 percent. What is the approximate real rate of interest? (Enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.) Approximate real rate % What is the exact real rate? (Do not round intermediate calculations. Enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)

Answer 1

Answer: Approximate real rate of interest = 5.2% and Exact real rate of interest = 5.058%

Step-by-step explanation:

Inflation rate, π = 2.8%

T- bills currently paying = 8%

Approximate real rate of interest:

So, approximate real rate of interest = current rate - inflation rate

= 8% - 2.8%

= 5.2%

Exact real rate of interest:

Exact real rate of interest =
`((1 + nominal rate)/(1 + inflation rate) )-1`

=

= 1.05 - 1

= 5.058%
