Mike considers to buy 1,000 bonds. The bond is semi-annual coupon bond with 10-year maturity, $1,000 par value bond with a 10 percent annual coupon, and 10 percent annual required rate of return? How much does it cost now if he wants to receive all the coupon payments and par values during the 10-year period? What would be the value of the bond if, just after it had been issued, the expected inflation rate rose by 3 percentage points, causing Mike to require a 13 percent return? What would happen to the bonds' value if inflation fell, and required rate of return declined to 7 percent?
