Determine the market yield on a 12-year note purchased today.  Describe the yield curve and provide a general interpretation of what implies about the economy.  
  
  Solution
a) According to Liquidity theory, the expected liquidity premium = average return of bond + constant premium
r = (r1 + r5 + r2)/3 + 3-year bond premium
= (3.42 + 4.35 + 3.69)/3 + .63 = 4.45%
b) Expected Yield is just the average of the n bonds of different durations or time to maturity
r = (4.02 + 4.02 + 3.42)/3 = 3.82%
c) Real world yield of a 3-5 path is the return of the average duration or 4-year note yield = 4.02%
d) If expectation hypothesis holds, then a 3 year note at beginning of year 5 will have 1 year left to maturity, According to the hypothesis, yield = discounted forward rate of 1 year note
Yield = 4.35/ 1 + 3.42% = 4.206%
