Suppose that the nominal rate of interest is 5 percent and the inflation premium is 1 percent.

What is the real interest rate? %

Alternatively, assume that the real interest rate is 4 percent and the nominal interest rate is 6 percent.

What is the inflation premium? %

1.     4%

2.    2%

Interest rates are rounded off to nearest whole number.

Explanation:

Fisher effect formula determines the relationship between the Nominal rate, Real rate and inflation rate.

Fisher effect formula is as follows

1 + nominal rate = ( 1 + real rate ) ( 1 + inflation rate )

1.

1 + 5% = ( 1 + real rate ) ( 1 + 1% )

1.05 =  ( 1 + real rate ) x 1.01

1 + real rate = 1.05 / 1.01

1 + real rate = 1.0396

real interest = 1.0396 - 1 = 0.0396 = 3.96% = 4%

2.

Inflation premium = [ ( 1+ nominal rate ) / ( 1+ real rate ) ] -1

Inflation premium = [ ( 1+ 6% ) / ( 1+ 4% ) ] -1

Inflation premium = [ ( 1.06 / 1.04 ] -1

Inflation premium = 1.0192 - 1

Inflation premium = 0.0192

Inflation premium = 1.92%

Inflation premium = 2%

rational decision making is a multi-step process for making choices between alternatives. the process of rational decision making favors logic, objectivity, and analysis over subjectivity and insight. the word “rational” in this context does not mean sane or clear-headed as it does in the colloquial sense.
