Consider one farmer using an aquifer. The volume of water in the aquifer is described by Xt+1 = Xt – Yt + Qt where Xt is the volume of water in period t, Yt is the extraction of water in period t and Qt is precipitation. The marginal net benefits of the farmer in each period are described by
MNBt = 20 - Yt
There are two periods. The amount of water in the first period is X0 = 7 and Q0 = 1.5. The farmer cannot use more water than available at the beginning of each period such that Yt ≤ Xt. With a discount rate of 10%, what is the efficient water use in the first period?
An oil refinery is willing to install a 60,000-lb/hour pump for $325,000 in 2020 when the pump index had a value of 500. The refinery must
also install another pump of the same size in 2024. Economic data shows that the pump index is forecast to rise by 5% annually.
What is the approximate cost of the new pump in 2024?
