1. A three-state transition model is shown in the following diagram:
σ
Alive Sick
µ v
Dead
Assume that the transition probabilities are constant at all ages with µ=2%, v=4%, ρ=1%, σ=5%.
Calculate the present value of a sickness benefit of 2000 p.a. paid continuously to a life now aged 40 and sick, during this period of sickness, discounted at 4% p.a. and payable to a maximum age of60.
2. A three-state transition model is shown in the following diagram:
σ
Alive Critically ill
µ v
Dead
Under these policies, a lump sum benefit is payable on the occasion that a life becomes critically ill during a specified policy term. No other benefits are payable.
A 20-year policy with sum assured 200,000 is issued to a healthy life aged 40. Calculate the expected present value at outset for this policy.
Assume that µ=1%, σ=5%, v= 3 µ and interest rate: 8% per annum.
