There are only two states of the world, when a person is well with probability (1-p) and ill
with probability p, where (1-p)= 1/3 and p = 2/3. Consider Adam who has utility function
U = (Y1, Y2,1 – p,p) = Y,"-P)Y?, where Y; is the income and i =1 is well and i = 2 is ill.
When Adam is well, he earns $1000, but when he is ill, he losses $300 in health
expenditures and earnings such that Y2 = $700. What is the maximum total premium that
Adam is still willing-to-pay?
