Increasingly regulation has taken the form of prohibition: Thou Shalt Not Do; no discharge of pollutants into the navigable waters by 1985. The environmental area is rife with examples of prohibitive policy. The thesis studies the formation and implementation of one of these -- the extremely prohibitive Endangered Species Act -- through case studies and measures of program output. Critics argue that prohibitive policy is bad because it does not allow for a balancing of the costs and benefits of alternative actions. They assume that implementation decisions are made solely on technical criteria, that outside parties are excluded from decision-making, and that agency discretion is limited. The thesis argues, however, that these are bad assumptions. Prohibitive policy is not implemented prohibitively. Resource scarcity and huge amounts of technical uncertainty force administrators to exercise discretion. The political context in which implementation takes place provides an opportunity for other interests to enter into decisions. Indeed, the thesis outlines a set of nonstatutory forces that shape implementation at least as much as the original statute. These include resource limitations, conflicting organizational goals, bureaucratic and scientific conservatism, internal advocates, constituent support groups, and legislative and judicial pressures. If prohibitive policy is not implemented prohibitively, why use it? The thesis argues that there are observable impacts of a prohibitive prescription that are useful to interest groups, agencies, and politicians. For example, prohibitive policies have a definite impact on the initial balance of power in a political negotiation. The analysis further identifies two substantive criteria for determining whether to advocate the use of prohibitive mandates in the future -- in cases of extreme risk, and where the goal is to define or protect a social ethic.

Key Provisions of the Endangered Species Acts 245 BIBLIOGRAPHY 248 v PREFACE This thesis tells several stories. On the surface, it examines prohibitive policy -- a kind of policy that prohibits a set of actions without allowing for a balancing of the costs and benefits of alternatives. But it also describes what happens during the implementation of a bill, how bureaucracies behave, and how professionalism and expertise influence the actions of administrative agencies. In addition, it deals with the process of policy formation and the development of regulatory policy. The thesis is also very much concerned with the endangered species issue. I started out -- and remain -- fairly well persuaded by the preservationists' argument. The statistics on declining diversity and changing world land use patterns are dramatic, promoting a sense of urgency about determining the values that should be assigned to plant and animal populations, and the institutions that should be established to manage them. Nevertheless, while I find the argument persuasive, I cannot defend it absolutely on the basis of the rational economic paradigm. I was relieved, therefore, to find that my hypothesis was true: There is in fact enormous amounts of uncertainty and latitude involved in these seemingly-technical decisions. Choice and judgment is pervasive. Supposedly the two things that are certain in life are death and taxes. Yet we all know people who don't pay taxes, and we have some latitude over when, how, and where we will die. Indeed, many cultures eliminate death by defining it away: Physical death is not death, but a step into eternal life. Discretion is prevalent in most facets of life, probably more so than we generally realize. Even in seemingly-irreconcilable vi conflicts between preservation and development, compromise between social objectives is usually possible if the incentives are large enough to force the parties into negotiation, and if the conflicts are approached creatively and early in the planning process. The endangered species problem has both technical and institutional dimensions. The institutional question is the toughest: Who can manage animal populations that -- God help them -- do not respect political boundaries? In the United States, we have only rudimentary land use planning. State-level critical areas programs are in an infant stage. National- scale land use management (and ecosystem preservation) is almost nonexistent. Yet the American institutional question is minor compared with that at the international level. Not only are there few international management institutions that work, but the issue of social conflicts is much more real. It is a lot easier to deny an agency a development project under conditions of affluence, than to deprive a poacher of his ability to feed his family: The ecological issue begs the social question. Until some of the problems of human society are solved, it is unlikely that much headway will be made in preserving ecological diversity. I am not optimistic. Yet if this analysis encourages several readers to think creatively about the problem, then it will have served a useful purpose. vii ACKNOWLEDGEMENTS As with all endeavors, this thesis is a collaborative effort: It draws on the ideas, energy, and support of others. To all of them, I owe an enormous debt. I would especially like to thank my advisor, Larry Susskind, and
