You are doing a cost benefit analysis of the costs and benefits of refurbishing abridge that is dangerous and needs repairs-how would you measure these costs and benefits. The bridge maintenance will save one life per year, how should this be measured in a cost benefit analysis?

I. The value of a life is immeasurable and worth infinite amounts of money

II. The economists best guess is that society is willing to give up about 9.6 million to save a life so the benefit is 9.6 million

III. The economists best guess is that society is willing to give up about 9.6 million to save a life so the benefit is 9.6 million in perpetuity which would be 9.6/.07= $137,142,000

a - I and II are true

b - I and III are true

c - II and III are true

d - Only III is true

e - None are true
