Suppose an individual is deciding between becoming a doctor or a surfer. To find the Internal Rate of Return (IRR) between these two options, one must find the r* that satisfies T In(t) T Is(t) (1+ r* )t 1=0 where r* is the IRR. Suppose we do this calculation and find that y* = .10. Would this individual become a doctor instead of a surfer if their interest rate is equal to .05? What about if their interest rate is equal to .80
