    Can anyone please explain the answer of question 7 to me? Why do you need to multiply e^(t+u+1) to the probability that a life who is sick at age 21+t is still sick at age 21+t+u?
    Many thanks.
     
  2. remember that present value thing

    you are missing a delta somewhere i.e e^[d*(t+u+1)] = v^(t+U+1). this factor is discounting to get present value. since life has been continuously sick for u+1, and before that, it took t time going from H to H.

    the whole thing is summing all the payoffs of v^(t+u+1)*dt each with probability yadi yadi yada

    i must admit i forgot about the whole discounting thing as well even though every question drums this into you!
