  2. Inflation Terminology – II • Actual Dollars (An ): Estimates of future cash flows for year n that take into account any anticipated changes in amount caused by inflationary or deflationary effects. • Constant Dollars (An’ ): Estimates of future cash flows for year n in constant purchasing power, independent of the passage of time (or base period).

  8. Practice Problem - How to Compare the Winning Prizes in Two Different Points in Time 1963 2004 Jack Nicklaus won his first Master Tournament in 1963. The prize was $20,000. Phil Mickelson won his first Master Tournament in 2004. The prize amount was $1.17M.

  9. Consumer Price Index 561.23 91.7 100 2004 1963 1967 Average inflation rate = 4.525%

  10. What is the worth of $1.17M in terms of purchasing power in 1963? The average inflation rate between 1963 and 2004 is about 4.53% per year. $1.17M in 2004 would have a purchasing power of $190,616 in 1963

  11. If Jack invested his prize money in 1963 at 5.65% (inflation-free interest rate), the prize money would grow to match Phil’s 2004 prize. $20,000 0 1963 $190,616 41 0 2004 1963
