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 construction workers spend money in the local economy having a multiplier effect of 80,000 dollars during construction.

I. This is 80,000 in benefits

II. This 80,000 would have been in the economy anyway and is not part of the benefits

III. Benefits should be higher because of the positive spillover effects beyond 80,000

a - I and II are true

b - I and III are true

c - II and III are true

d - Only II is true

e - None are true
