The Economical Management of Multispecies Fisheries: Reply
回应Anderson的观点,讨论多物种渔业在没有资源产权时的自我调节能力,以及管理对种群规模的控制效果,认为这些因素降低了监管的必要性和预期收益。
I believe the fundamental source of difference between Anderson's view and mine concerns (1) the extent to which the common exploitation of complex, multiple species ecosystems, such as marine fisheries, is capable of self-regulating behavior in the absence of resource property rights, and (2) the extent to which management can exercise long-term control over the size of individual species populations. On almost all other basic points, I believe our perspectives are fairly close. Consequently, Anderson and I agree that the complex biological and human behavior of these systems raises the costs and, thereby, adversely affects the possibilities of regulation that is, on net, beneficial. We also appear to agree that the extent of that adverse cost effect is ultimately an empirical matter determined by the particulars of each fishery. We tend to disagree with regard to the potential magnitude of regulatory benefits because of the self-regulatory and control questions. This, of course, leads to a final disagreement about preferred management approaches. I don't believe that Anderson has accepted (or for that matter responded to) the points I tried to make about either the self-regulatory tendencies or the population control problem in these systems. From my perspective, both these tendencies strongly reduce the need for and the expected benefits of regulation; they also suggest the advantages of a simple regulatory system that purposefully reinforces inherent self-regulatory tendencies (e.g., resource sensitive information networks). In my original paper I did not construct a
