The figure below presents the marginal revenue that a farmer can obtain from water, and the marginal cost to the farmer to move the water to her land. There are two farmers with the exact same marginal revenue and marginal cost curves, but Farmer A is upstream, and therefore allowed to extract her water first. There is only 400 acre feet of water available for the two farmers. If there is no
water market, Farmer A would use ________ acre feet and Farmer B would use ________ acre feet. Under the efficient allocation, Farmer A would use ________ acre feet of water, and Farmer B would use ________ acre feet.
