This essay reasses the assumptions of the Brams-Fishburn theory of approval voting, and proposes modifications to make the theory correspond better with likely voting choices. With a small number of candidates, voters who use the inadmissible strategy of voting for all candidates can help to produce a result that better reflects the voters' wishes than is possible with admissible strategies, so we propose a widening of the definition of admissibility to encompass this case. With more than three candidates, we define first-order admissible strategies, which are the most likely strategies to be used in practice, and are also strongly sincere, in that a vote for any candidate is always accompanied by votes for all more or equally-preferred candidates. Their number is less under approval voting than under plurality voting. Both proposed modifications strengthen the technical arguments favoring approval voting over plurality voting.  相似文献

Two implications from this research are noted. First, from a researcher's viewpoint, our research suggests the importance of age, wealth, tax rates, and marital status as determinants of political contributions by top U.S. wealth-holders. Therefore, these factors should be included in aggregated models that attempt to analyze the relations between such variables as voting, campaign expenditures and the outcomes of elections. Second, from politicians' viewpoints, this research suggests that individual economic variables such as marginal tax rates and wealth are major determinants of individual decisions to contribute to politicians. Assuming that such contributions reflect votes, this research suggests the relative importance of focusing campaign promises on economic variables — a strategy that low tax politicians like Ronald Reagan and George Bush may keenly be aware of.The views presented are those of the authors and do not necessarily represent those of the Treasury Department.  相似文献

The 1997 Kyoto Protocol establishes an international institutional framework for domestic responses to climate change that links emission targets for developed countries to international market mechanisms. Although these flexible mechanisms allow developed countries some leeway in how they meet their commitments to reduce greenhouse gases, the protocol also establishes a normative framework that directs domestic policy responses along certain paths. Applying insights from sociological institutionalism and constructivism in international relations, this article argues first, that the climate change regime reflects and further institutionalizes the prevailing international normative structure in the environmental issue area, characterized as liberal environmentalism. Second, these norms, as embodied in the climate change regime, have enabled and constrained climate change policy development in Canada, one of the worlds largest emitters of greenhouse gases per capita. International norms can shape or redefine domestic interests, enable policies in conformity with those norms, and create normative pressures for change by linking with extant domestic and foreign policy norms. Uncovering this international institutional-domestic policy interaction resolves the paradox of Canada's promotion of commitments and mechanisms consistent with its domestic interests and institutional constraints, but eventual commitment to action well beyond what those constraints dictate. This commitment continues despite Kyoto's uncertain future. The findings also point to lacunae in the literature on regime compliance and effectiveness more broadly, especially its dominant rationalist variant.  相似文献

Conclusions The history of U.S. and Canadian risk assessments for dioxin is an increasingly familiar tale of debates within the scientific community played out in the political arena. Uncertainty among scientists creates the possibility of large disparities between different governments' policies. However, the pattern of differences that emerges reflects the context in which science policy decisions are made within each agency and within each country. The political environment has implications not just for how mandated science is received, but for how it is conducted.Many features of the dioxin case are consistent with observations by others. In the cases of formaldehyde, alachlor, alar, and amaranth, EPA relied on mathematical models to assess the risks of potential carcinogens, while Health and Welfare Canada relied on the more traditional safety factor approach.35 This body of evidence is suggestive of national styles of transscience. Features of the U.S. style include explicit rationales for regulatory decisions, reliance on consistent and explicit risk assessment principles, and public debate over scientific aspects of public policy. The Canadian style is exemplified by closed decisionmaking, case-by-case review, and the absence of public discussion of the scientific basis for government decisions.The differences between FDA and EPA in this case study suggest an important caveat, however. The U.S. style is most clearly reflected in the implementation of the non-discretionary environmental, health and safety statutes passed by the U.S. Congress since 1970. More closed and traditional styles of regulatory decisionmaking may survive within the U.S. as vestiges of a more deferential past.Even less than pure science, trans-science is not a universal enterprise. When scientists do reach agreement, it can be a powerful force that can even overcome political and national differences (Haas, 1989). However, when science is uncertain, as is typically the case in assessing the risks of toxic chemicals, there is more room for political factors to shape the way different countries interpret science in making policy decisions.  相似文献

Given rapidly increasing losses from extreme climate events, the world community already has a common interest in action to mitigate and adapt to climate change. However, this common interest is not well served through continued promotion of either mandatory (legally-binding) policies or do nothing policies by various participants in the regime established by the U.N. Framework Convention on Climate Change. The common interest would be better served by a third way, comprised of voluntary no regrets policies that are commensurate with the limited political power of the regime and already have succeeded on small scales in reducing vulnerabilities to extreme climate events and in reducing greenhouse gas emissions. Both mandatory and do nothing policies, as well as the regime itself, have depended upon scientists for political support in the past. But scientists might better serve the common interest of the world community through support of a third way in the future.  相似文献

In this paper, we consider the problem of determining the optimalteam decision rules in uncertain, binary (dichotomous) choice situations. We show that the Relative (Receiver) Operating Characteristic (ROC) curve plays a pivotal role in characterizing these rules. Specifically, the problem of finding the optimal aggregation rule involves finding a set ofcoupled operating points on the individual ROCs. Introducing the concept of a team ROC curve, we extend the method of characterizing decision capabilities of an individual decisionmaker (DM) to a team of DMs. Given the operating points of the individual DMs on their ROC curves, we show that the best aggregation rule is a likelihood ratio test. When the individual opinions are conditionally independent, the aggregation rule is a weighted majority rule, but with different asymmetric weights for the yes and no decisions. We show that the widely studied weighted majority rule with symmetric weights is a special case of the asymmetric weighted majority rule, wherein the competence level of each DM corresponds to the intersection of the main diagonal and the DM's ROC curve. Finally, we demonstrate that the performance of the team can be improved by jointly optimizing the aggregation rule and the individual decision rules, the latter possibly requiring a shift from the isolated (non-team) optimal operating point of each DM.Research supported by NSF grant #IRI-8902755 and ONR contract #N0014-90-J-1753.  相似文献

Several different explanations of policy change based on notions of learning have emerged in the policy literature to challenge conventional conflict-oriented theories. These include notions of political-learning developed by Heclo, policy-oriented learning developed by Sabatier, lesson-drawing analyzed by Rose, social learning discussed by Hall and government learning identified by Etheredge. These different concepts identify different actors and different effects with each different type of learning. Some elements of these theories are compatible, while others are not. This article examines each approach in terms of who learns, what they learn, and the effects of learning on subsequent policies. The conclusion is that three distinct types of learning have often been incorrectly juxtaposed. Certain conceptual, theoretical and methodological difficulties attend any attempt to attribute policy change to policy learning, but this does not detract from the important reorientation of policy analysis that this approach represents.  相似文献

The mode of operation and military strategy of the Israeli army provide an example of an effective utilization of the potential military advantage of a relatively modernized society over a less modernized rival. The Israeli command communication and control system is characterized by a built in operational flexibility in attaining its objectives.Each component formation has the capacity for on the spot utilization of feedbacks in responding to emergent situations while coordination is ensured by optional headquarters control. The effect of superior flexible responsiveness is maximized by the adoption of military strategies which are likely to result in increasing the complexity and uncertainty of battlefield conditions such as blitzkrieg and indirect approach. The rationalle of such a strategic approach lies in the assumption that, given the approximately zero sum characteristics of warfare, the more flexible of two rival military command systems is likely to benefit from an extra pressure put on both.  相似文献

The Delaney anticancer amendment to the Food, Drug, and Cosmetic Act of 1938 is a prominent example of zero risk legislation. The relevant clauses prohibit a finding of safety for any relevant substance found to induce cancer in humans or animals. It is argued that the Delaney approach to safety regulation is not only misguided, but that relaxation of the law - for example, to permit substances that pose insignificant cancer risks - would produce only marginal improvement in regulation. A major shift in regulation that permits some form of cost-benefit analysis is the only way to move toward rational policy choices.Professor of Economics, Rutgers University.

The development of increasingly transnationalized (globalized) financial markets raises several key issues for the analysis of politics, public policy, and the national state. This article suggests that financial globalization increasingly constrains policymakers and circumscribes the policy capacity of the state. After looking briefly at a range of approaches to the process of financial globalization itself, the author suggests that technological change is the main independent variable, by reducing transaction costs and dramatically increasing the price sensitivity of financial markets across borders, while at the same time making possible a range of economies of scale. These very developments have a knock-on effect throughout the domestic and international economies. They in turn make obsolescent the political economies of scale — the governance structures — which have characterized economic policy in modern nation-states, undermining the capacity of the state to produce public goods. At the same time, globalized financial markets interact with rapidly changing interest group structures and divided state structures, especially through regulatory arbitrage. Without the development of transnational regimes capable of regulating global financial markets, the structural basis of the national state itself is being undermined, and Polanyi's Great Transformation is over.  相似文献

Over the last ten years, policy change in the third world has become a matter of considerable intellectual and practical importance. For the theoretically inclined, how one explains changes in the behavior of the state is the main issue. Both Marxian and liberal orthodoxies had a tendency to read off state behavior from the power relationships at the level of the society, though differing in the way they conceptualized power. The return of institutional and state-centric explanations over the last decade has attempted to reverse this bias by looking more closely at the power struggles within the state institutions. For the practically inclined, the powerful intellectual rationale behind so many policy recommendations has often been puzzlingly lost in the maze of politics. What interests impede the implementation of good ideas, what institutions block getting policies right - these are some of the key questions on the agenda of international development institutions. Responding to these varied concerns, this paper analyzes a particularly successful case of policy change. While most of third world was still experimenting with land reforms and cooperatives as the ways to develop agriculture, India in the mid-1960s switched to producer price incentives and investments in new technology, a change that is widely believed to have turned India from a food-deficit to a food-surplus country. The focus is on how ideas, interests and institutions interacted to produce the change.  相似文献

Efforts by both natural and social scientists have brought significant new bodies of information to bear on natural resources policy making. Among these have been new insights in conservation biology and landscape ecology, new methods for valuing intangible resource benefits, and new frameworks for resource accounting. The use of these new sources of information is analyzed from a Lasswellian policy process perspective, with illustrations from recent experience with U.S. national forest planning. A distinction is made between the impact of new information on ordinary as contrasted to constitutive policy making. This experience suggests that these new sources of information may increase emphasis on sustainable, multiple benefit use of resources, but they can also shift power away from non-expert actors, undermine rights arguments, polarize debates over appropriate resource use, and delay timely decisionmaking.  相似文献

The 1970s spawned a first generation of growth controls which featured explicit (or implicit) restrictions on residential housing construction. These restrictions were typically implemented in small, affluent, and predominantly white suburban communities. Policy analysis responded by focusing almost singlemindedly on how such supply-side restrictions might increase housing prices and drive out the poor. The 1980s and 1990s have, however, given birth to a more comprehensive second generation of controls which many major cities and metropolitan areas are considering. This generation ties commercial and industrial as well as residential development to the reduction of the negative externalities and congestion costs associated with growth. To fully evaluate this second generation, policy analysis must take into account not only housing price effects and the rate of job creation but also the full range of amenity effects associated with differing rates of growth and attendant levels of traffic congestion, air pollution, and other public bads. We develop a framework for such second generation growth control analysis using San Diego as an example.  相似文献

This paper departs from the Tullock cost paradigm that views competition for monopoly privilege as a welfare-inimical process that wastefully dissipates preexisting producers' surplus and, occasionally, leads to inefficient increases in costs and counterproductive uses of scarce resources. The potential availability of rent-seeking may bring about the elimination of inefficient regulatory regimes that retard or prevent the introduction of cost-reducing innovations. Air quality management is but one area in which innovation rent-seeking holds promise for concrete welfare gains. Researchers may wish to focus on institutional mechanisms designed to overcome the transactions costs and free rider disincentives to the formation of a coalition to seek innovation rents. An example of such a mechanism might be a joint venture that requires all venture members to engage in lobbying and to contribute to collective research efforts. These unaddressed questions await future research.The authors are grateful for the insightful comments of Gordon Tullock, Robert D. Tollison, Michael T. Marlow and J.R. Clark.

The Agency for International Development (AID), the U.S. Government's principal dispenser of foreign economic assistance, is struggling to define its mission in the post Cold War era. AID staff and overseas presence has contracted in recent years following reinvention reforms. But reinvention has not clarified the agency's mission nor protected it from powerful critics. AID's future depends on its ability to develop a mission that excites popular demand. Agency reformers promote foreign aid as a means to advance sustainable development in developing countries. But AID's sustainable development mission lacks credibility because it excludes references to reforms required in post-industrial societies. Participation of U.S. local interests in aid management and more effective promotion of familiar premises for aid (many of them consistent with the tenets of sustainable development) are essential elements of a revitalized foreign aid program.  相似文献

The societal transformation underway in Poland createda fundamental challenge to the occupational health and safety system, as the ideological and administrative principles on which it was founded vanished along with the communist-dominated regime. This paper examines the regulatory reform in Poland during the 1990s: its structural elements, implementation record and future prospects. Drawing on five case studies of privatized firms, a mailed questionnaire, and policy and institutional analysis, we find that Poland had considerable success in developing an effective regulatory system for managing occupational health hazards in privatized sector while also achieving considerable socioeconomic progress. The fundamental legitimacy of the regulators and regulatory process, the availability of information about firms and regulatory intents, and the capacity for case-specific decision making, are among the key explanatory factors. The case-specific implementation in Poland is consistent with models advocated by several authors in relation to other industrialized European economies (termed variously as negotiated compliance, tit-for-tat, cooperation-deterrence), despite a uniquely Polish context related to the continuing legacy of the communist era. The study also shows how in Poland a good fit between regulatory institutions and policies on the one hand, and their social context on the other hand, contributes to the effectiveness of the regulatory system.  相似文献

This paper evaluates the use of climate-based information in drought mitigation in Ceará, Northeast Brazil. It examines two policies – a seed-distribution program (Hora de Plantar) and the Emergency Drought-Relief Program – that use climate information produced by FUNCEME (Cearás Foundation for Meteorological and Hydrological Resources) to implement drought planning. It argues that, in politically charged policy-making environments, the use of climate forecast information may go beyond its problem-solving function to influence broader issues of accountability and democratization. In Cearás politically charged environment, technocrats rely on scientific information about climate to insulate policy-making from both political meddling and public accountability. However, insulation afforded by the use of climate information has played different roles in the policy areas examined in this study. While in drought emergency-relief planning the use of climate information critically contributed to the democratization of policy implementation, in agricultural planning, it worked towards further insulating decision-making from public accountability and client participation. Thus, the use of climate information is context-dependent, that is, the distribution of costs and benefits associated with information use in policymaking depends on the social, political, and cultural context in which information producers and users work. Moreover, climate information can be used in ways – positive or negative – significantly different from the use that information producers intended.  相似文献

A theoretical and empirical basis for comparing stocks of human capital in the American states is developed. Human capital report cards are measurement tools allowing states to benchmark their production and retention of the knowledges, skills and abilities required by economic development and public education policy making. A prototype report card is created from 12 indicators — seven of which theoretically capture a basic dimension of human capital and five of which measure complex human capital. Principal component factor analysis reveals that for the 50 states in the 1980s the concept of human capital is a multi-dimensional construct rather than a unidimensional one and that basic and complex factors do in fact distinguish the major cleavages among human capital measures. A further finding is that the relative positions of the 50 states can be plotted on the two dimensions with practical payoffs accruing to state and local planners.  相似文献

There is a near consensus that organized special interests use influence to expand government into activities that are detrimental to the public at large. Consequently, as Lee (1989) suggests, it would be desirable if the general public had more control over political decisions — if government were more responsive to the public interest. However, the public interest like rent-seeking, is a subjective concept (Pasour, 1987).The possible existence of a desirable minimal state is not disproved by an approach that assumes utilities are interpersonally comparable. Individual utilities are subjective and ordinal and hence, cannot be added or weighted to determine the level of government that is socially optimal. If one accepts the subjectivist approach, it follows that no one can decide upon any policy whatever in the absence of an ultimate ethical or value judgment (Rothbard, 1982: 212). In this respect, determining the desirable minimal state is no different from determining whether an individual government program is desirable (or whether it represents rent-seeking waste).  相似文献

Analyses of the same NORC poll relied on by Hyman and Sheatsley and a 1994 poll for theTimes Mirror Center for The People & The Press show that sizable portions of the U.S. public were know-nothings on both occasions. OLS regressions on both polls show that, although there are slight differences, essentially the same factors affect knowledge of international politics in 1946 and 1994. At bottom, Americans tend to be uninformed about foreign affairs because they are inattentive to events abroad. If it is true, as some students of U.S. foreign policy claim, that public opinion has an important and growing impact on national security policy, widespread public ignorance recalls Lippmann's concern about the democratic malady.  相似文献
