Tutorial Answers: Chapter 4 2. No, because the present discounted value of these payments is necessarily less than $10 million as long as the interest rate is greater than zero. 5. $2,000 $100/(1 i) $100/(1 i)2 . . . $100/(1 i)20 $1,000/(1 i)20. 6. 25% ($1,000 – $800)/$800 $200/$800 0.25. 15. The economists are right. They reason that nominal interest rates were below expected rates of inflation in the late 1970s, making real interest rates negative. The expected inflation rate, however, fell much faster than nominal interest rates in the mid-1980s, so nominal interest rates were above the expected inflation rate and real rates became positive.
