2 1 point A city is considering building a new port, which will have an immediate cost of $800m to build, and a net benefit of $25m each year forever (accruing at the end of each year). With probability 0.5, the new port will damage the population of dolphins. If the damage occurs, economists estimate that it would be $15m per year forever (accruing at the end of each year).
