Limits to the Privatization of Fishery Resources: Comment
回应Clark等人2010年的研究，指出即使内在增长率低且贴现率高，私有化也不必然导致鱼类种群灭绝，动态BMey可能仍高于最大可持续产量对应的生物量。
This paper responds to the key findings of Clark, Munro, and Sumaila (2010). We restrict our response to (1) biomass targets and what they do not imply about resource ownership, (2) harvesting costs and the stock effect in fisheries and their implica tions for fisheries management, and (3) the effect of the intrinsic growth rate on optimal extinction and also dynamic ??mey?the level of the biomass that maximizes the sum of discounted economic returns from fish ing. Despite what is asserted by Clark, Munro, and Sumaila (2010), that the deliberate extermination of a fish popula tion may be the private owner's optimal strategy, we show that such an outcome cannot be presumed and that even with a very low intrinsic growth rate and a much larger discount rate, dynamic BMey may still exceed the biomass that maximizes the
