Problem 1 (14 points): Assume the forward rates for the next 2 years are given by: r(0.5)=6%, r(1)=7%; r(1.5)=7.5% and r(2)=8%. Keep at least 6 decimal digits while doing calculations and reporting the answer.

d) (5 points) Assume that a 12% coupon bond maturing in 2 years sells for $108 while an 8% bond maturing in 2 years sells for a fair price (that you were expected to compute in part (b)). Assume also that there is a 2-year zero-coupon bond selling for a fair price (based on the given forward rates). How can you make an arbitrage by trading only these three bonds? State how many of each bond you want to buy or sell (assume you can freely short-sell any bond) and your net cash flow at each point in time. Note that to make arbitrage you must have non-negative profit at any point in time and strictly positive profit at least at one point in time.
