Consider the following spot interest rates for maturities of one, two, three, and four years.

r₁ = 5.2% r₂ = 5.6% r₃ = 6.3% r₄ = 7.1%

Assuming a constant real interest rate of 2 percent, what are the approximate expected inflation rates for the next four years? (Do not round intermediate calculations. Enter your answers as a percent rounded to 2 decimal places. Omit the "%" sign in your response.)

I₁ %

I₂ %

I₃ %

I₄ % hint Use the Fisher hypothesis and the unbiased expectations theory.
