Answer:
Please take a look to the following explanation
Step-by-step explanation:
1) The expectations hypothesis of the term structure of interest rates is the proposition that the long-term rate is determined purely by current and future expected short-term rates, in such a way that the expected final value of wealth from investing in a sequence of short-term bonds equals the final value of wealth from investing in long-term bonds.
2) For 2019, (1 + f1t) = (1 + i2t)2/(1 + i1t) = (1.05)2/(1.04)
Or, (1 + f1t) = 1.0600
Or, f1t = 0.06 or 6%
For 2020, (1 + f2t) = (1 + i3t)3/(1 + i2t)2 = (1.06)3/(1.05)2
or, (1 + f2t) = 1.080
or, f2t = 0.08 or 8%
