本文分析了一个国家拥有一种用之不竭但有不同等级和不同成本的资源时的最优枯竭政策。假设成本随着累积开采而增加，直到某一点，但在达到“后备”供应时保持不变。这一模型准确地模拟了最终可能从海相或结晶岩中提取的矿物的供应条件。重点放在沿最优（竞争）路径的价格行为上，并表明价格-成本关系与指数增长的版税的标准关系非常不同。
This paper analyzes the optimal depletion policy for a country with a resource which is inexhaustible but available in various grades and at various costs. Cost is assumed to increase with cumulative extraction up to a point, but then to remain constant as a "backstop" supply is reached. This models accurately the supply conditions of minerals which may eventually be extracted from marine sources or crystal rocks. Emphasis is placed on the behavior of prices along an optimal (competitive) path, and it is shown that the price-cost relationship is very different from the standard one of an exponentially growing royalty.
