Find the current market price of a 20-year, 9% coupon rate bond with par value of $1,000 if interest is paid annually and if current market rates are (a) 11% or (b) 7%. What are the current market prices if everything is the same except the bond has only (1) 10 years to maturity, or (2) 2 years to maturity? What can we say about the relative influence of changing market interest rates on the market prices of short-term versus long-term bonds? Can you speculate on why this is so
