This paper estimates risk reductions for each layer of security designed to prevent commercial passenger airliners from being commandeered by terrorists, kept under control for some time, and then crashed into specific targets. Probabilistic methods are used to characterize the uncertainty of rates of deterrence, detection, and disruption, as well as losses. Since homeland security decisionmakers tend to be risk‐averse because of the catastrophic or dire nature of the hazard or event, utility theory and Monte Carlo simulation methods are used to propagate uncertainties in calculations of net present value, expected utility, and probabilities of net benefit. We employ a “break‐even” cost‐benefit analysis to determine the minimum probability of an otherwise successful attack that is required for the benefit of security measures to equal their cost. In this context, we examine specific policy options: including Improvised Physical Secondary Barriers (IPSBs) in the array of aircraft security measures, including the Federal Air Marshal Service (FAMS), and including them both. Attack probabilities need to exceed 260 percent or 2.6 attacks per year to be 90 percent sure that FAMS is cost‐effective, whereas IPSBs have more than 90 percent chance of being cost‐effective even if attack probabilities are as low as 6 percent per year. A risk‐neutral analysis finds a policy option of adding IPSBs but not FAMS to the other measures to be preferred for all attack probabilities. However, a very risk‐averse decisionmaker is 48 percent likely to prefer to retain FAMS even if the attack probability is as low as 1 percent per year—a level of risk aversion exhibited by few, if any, government agencies. Overall, it seems that, even in an analysis that biases the consideration toward the opposite conclusion, far too much may currently be spent on security measures to address the problem of airline hijacking, and many spending reductions could likely be made with little or no consequent reduction of security.  相似文献

Political theorists have developed well‐defined normative understandings of what constitutes ethical political conduct. Based on democratic theory as well as the demands of practical politics, these understandings prescribe certain types of behaviour and proscribe other types. However, it is unclear to what extent this normative framework has resonance for ordinary citizens. This article demonstrates that attention to politics tends to increase the resonance of this normative framework. The analysis identifies three norms about the holding of public office that are expected to structure citizens' ethical judgments: the avoidance of conflicts of interest; conformity with the law or institutional rules; and the maximisation of the public good. The article assesses the importance of these norms in structuring judgments by means of an experiment embedded in a population survey conducted in Great Britain. The analysis finds that informational cues pertaining to conflict‐of‐interest avoidance only condition responses among the attentive, while information pertaining to law conformity has far wider resonance. This finding has implications for approaches to political ethics focusing on normative considerations that appear to have low salience for much of the general public.  相似文献

Normative political theory over recent decades has focused mainly on what ought to be done as far as migration policies are concerned. It faces a basic challenge, which stems from two competing, yet equally fundamental, ideals underpinning liberal democratic societies: a commitment to moral universalism and the exclusionary requirement of democracy. The objective of this special issue, ‘New Challenges in Immigration Theory’, is to provide a conceptual overview of (some) immigration theories and to highlight the challenges new streams of immigration pose for normative (political) theory and liberal democratic practice. The issue will consider how to reconcile state-based exclusion with a commitment to equal moral concern for all persons, by focusing on the non-standard immigration questions that have so far been ‘neglected’ by normative political theory. In line with this objective, the issue will discuss some of the inadequacies of the dominant political theories of immigration and show how such theories can be expanded to take account of new migration challenges such as brain drain, climate migration, detention of irregular migrants and asylum seekers, rights of labour migrants, transnational networks of movement, and so on.  相似文献

The bad news is that critics of the quantitative movement in policy and political science are right (so far). Widely accepted quantitative models of politics promote cynicism and counter-productive uses of government power. Mainstream social science provides a perverse basis for policy analysis. The good news is that there is no sound scientific reason for the schism between so called "empirical" and "normative" theories of politics. Traditional theories of politics, which show how government power can be used to serve the public interest, can be quantified and tested as empirical theory. The resulting scientific normative theory provides a constructive foundation for policy analysis.  相似文献

The modern theory of voting usually regards voters as expected utility maximizers. This implies that voters define subjective probabilities and utilities for different outcomes of the elections. In real life, these probabilities and utilities are often highly uncertain, so a robust choice, immune to erroneous assumptions, may be preferred. We show that a voter aiming to satisfice his expected utility, rather than maximize it, may present a bias for sincere voting, as opposed to strategic voting. This may explain previous results which show that strategic voting is not as prevalent as would be expected if all voters were expected utility maximizers.  相似文献

Abstract. Those writing textbooks on comparative European politics, or the cross–national study of European democracies, have a number of key choices to make. They must decide whether to cover Western Europe as well as Central and Eastern Europe; whether to focus on a limited number or a broad range of countries; whether to include the EU in the analysis or exclude it; whether to adopt a thematic or a country–by–country approach; whether to survey events or test a broader argument; and whether to focus on the politics of institutions and representation or to include more social and economic–oriented concerns as well. The evidence from the most recently published texts in this area is that different writers make different choices. Moreover, the context within which European politics now operates also suggests that their choices are becoming increasingly difficult ones to make.  相似文献

Richard McKelvey predicts that candidates will converge to an equilibrium if candidates and voters maximize their utility and voters' preferences conform to stringent assumptions. Although there are discrepancies between electoral data and the requirements of the theory, an analysis of 1972 and 1976 survey data lends support to basic components of the theory. First, most voters did choose the candidate who provided the greater utility. Second, voter distribution was not asymmetrical enough to allow a candidate to win by moving away from the median toward a concentration of voters. Third, the winning strategy for a candidate was to locate at or near the median. While formal theories' predictions will not hold in their precisely stated form, the assumptions can be robust enough to offer an explanation of electoral choices.  相似文献

The article discusses methodological issues in normative political theory. The basic assumption is that normative theory has a dual purpose in both establishing valid principles of differentiating right from wrong and influencing actions and institutions in the right direction. The article starts by distinguishing between two approaches to normative political theory: one stresses the interpretation of existing ideas and conventions; the other takes on the constructivist task of finding out what is really right. Then the relationship between theory and practice is explored. The question is how philosophical arguments can instigate practical reform. It is argued that practical considerations should be incorporated as an explicit element of normative political theory. The recommendation is. in particular, that philosophical theories enter into dialogue with the moral conventions of everyday life. whose normative force people already acknowledge.  相似文献

Abstract.  Theories of coalition formation represent a diverse set of arguments about why some government coalitions form while others do not. In this article, the authors present a systematic empirical test of the relative importance of the various arguments. The test is designed to avoid a circularity problem present in many coalition studies – namely that the theories are tested on data of national government coalitions in postwar Europe: the very data that gave rise to the theories in the first place. Instead, the authors focus on government coalitions at the municipal level. They base their analysis on an expert survey of almost 3,000 local councillors from all municipalities in Denmark. They use conditional logit analysis to model government formation as a discrete choice between all potential governments. The analysis confirms some, but far from all, traditional explanations such as those based on office and policy motives. At the same time, the analysis raises the question of whether actors really seek minimal coalitions.  相似文献

Abstract

The purpose of this paper is to argue for the importance of attention to facts in normative theorising. I discuss the problems that arise from both not displaying such attention (as some idealists do) and from doing so in the wrong way (as, for example, realists do). I propose a different brand of theorising – fact-sensitive political theory, which aims to avoid these two problems by paying attention to key facts while retaining a solid normative anchoring in abstract normative principles. The merit of abstract vs. non-abstract reasoning is that the normative debate is not torn between two distinct ends of a spectrum in the way the idealist–realist debate is. By contrast, the locus of the investigations is vertical in the sense that abstract and concrete normative discussions are given equal status and can co-exist compatibly. One of the main differences between abstract and concrete normative principles is whether abstract or concrete facts are considered necessary for the determination of the normative principles. The fact-sensitive account of normativity is neither realist nor non-ideal: it is an ambitious and demanding normative theory that contains both abstract and concrete normative reasoning. The fact-sensitive account of political theory meets the two criteria set out in this article: to integrate concrete and empirical facts about the subject matter and to subject the selection of facts to theoretical and methodological discussion and justification.  相似文献

The “rights revolution” has become a central feature of modern political consciousness and has resulted in a proliferation of theories about children's rights. Yet mainstream liberal theories in which children's rights are theorized rarely take children's rights as citizens seriously, due to the normative stance of liberal theories that construct children in terms of “not-yet-citizens”. This article argues for a difference-centred theory of children's citizenship rights by situating the analysis within feminist, anti-racist, gay, lesbian and transgendered theories of citizenship that are difference-centred. It discusses an alternative, difference-centred, articulation of children's citizenship rights through an analysis of their rights of liberty and equality. Through a broadening of liberal, normative notions of liberty defined around exercising individuated autonomous decision-making or the participation in citizenry duties, the article re-defines children's rights of liberty in relational terms that addresses their agency and acknowledges their presence as participating subjects in the multiple relationships in which they interact. It also re-articulates their rights of equality from a mainstream liberal interpretation of “equality-as-same” to one that treats children as “differently equal” members of the public culture in which they are full participants. Normative social institutional practices and assumptions become the focus of the analysis, which concludes that these have to change as they act as barriers that exclude and marginalize children's citizenship rights on the basis of their difference (real and constructed) from an adult norm assumed of citizens.  相似文献

This article uses survey data to study the impact of democracy on the demand by poor citizens for government redistribution. Taking the well‐known Meltzer‐Richard theory as the point of departure, three arguments are presented as to why such a demand should be stronger in democracies than in autocracies: in democracies low‐income groups are: (1) exposed to elections that can make a policy difference: (2) better informed about the income distribution; and (3) better equipped to process such information. The argument receives empirical support in a Bayesian multilevel analysis which combines 188 World Values Surveys with cross‐sectional and longitudinal macro data from 80 countries.  相似文献

While the normative ecological roles of a government's effect on consumers' proecological attitude and green consumerism have received less attention, greenwashing interaction effect remains unexplored. Building on the two normative theories – stakeholder theory and social contract theory, the study tests a theoretical model integrating mediating and moderating relationships using survey data from 202 consumers across China. Results show a government's normative ecological roles positively and significantly on consumers' proenvironmental attitudes and green consumerism. It also confirms the mediating roles of the proenvironment between the ecological roles of a government and green consumerism. Further, tests of greenwashing moderation effect generated mixed outcomes. Insignificant greenwashing interaction effect between proenvironment and green consumerism, but, it proved significant interaction between ecological roles of a government and green behavior. The study proposes research avenues on how researchers can step up the theme and policy implications to practitioners.  相似文献

A neoprogressive research agenda is developed to challenge public choice theory's position as the new orthodoxy in both understanding and guiding policy choices about urban service delivery. Such a challenge requires more than accumulating negative empirical tests. Rather, we must accept the new burden of proof laid on proponents of progressive reform institutions by the theories of nonmarket failure and quasimarkets, ideas that undermined the intellectual pillars supporting progressive reform institutions and can only be challenged by new ideas. Public choice theory itself, broadly considered, is proposed as a valid source of such new ideas. Three research programs, in part already underway, are outlined as essential building blocks in the research agenda, focusing, respectively, on blunting the rough edges of the theory of nonmarket failure, coordinating the empirical critiques of quasimarkets in a new theory of quasimarket failure, and developing the new institutionalism so that it can provide the basis for comparing the production outcomes of alternative urban institutions.  相似文献

Voters in polities that make heavy use of direct democracy are frequently confronted with ballots that contain a multitude of propositions. Claims that direct legislation elections overwhelm voters with choices they are not competent to make should particularly apply to such demanding settings. Yet, evidence on the effects of lengthy ballots on voting behavior is scant. This study reviews theories of decision-making under uncertainty, and tests their predictions in a mixed heteroscedastic model of vote choice that is fitted to a unique collection of survey and contextual data on Swiss referendums. Increasing ballot length is demonstrated to interfere with the voters’ ability to translate their political preferences into consistent policy choices.  相似文献

City managers play an influential role in brokering intergovernmental service arrangements on behalf of their jurisdiction, yet their motivations for doing so are not well understood. One argument, drawn from theories of bureaucratic entrepreneurship and ambition theory, suggests that cities with managers who are motivated to advance their careers will parlay more interlocal service delivery as means of capturing economic efficiencies. Such strategies serve to build their personal resumes of career achievements. An alternative argument suggests more altruistic motives, including a desire for increased social equity and valuing the common good of the region, compel city managers to pursue interlocal service arrangements. These competing theories are tested on 134 large municipalities, using survey data from the city managers of these jurisdictions, coupled with interlocal revenue and expenditure data for these cities. Results yield greater support for the first theory. However, progressive ambition possesses complex consequences for interlocal service delivery choices. Jurisdictions managed by city managers with career‐enhancement ambitions are more likely to sell services to other local governments. Yet, they are significantly less inclined to buy services from other jurisdictions, thereby underscoring entrepreneurship in shaping managers’ professional trajectories.  相似文献

ABSTRACT

Political marketing is a relatively new approach to analysing political activity that draws upon management marketing assumptions to describe political behaviour. These assumptions are explicitly grounded in neoclassical economic assertions about behaviour. In political science these assumptions are utilised by orthodox rational choice theory. Thus, political marketing can be located within this perspective. Rational choice provides a series of analytic models through which ontological implications can be derived, and predictions made. Yet, the political marketing approach seeks to build upon orthodox rational choice accounts, by introducing a normative element to this perspective, prescribing the internalisation of these assumptions in order to achieve the desired objective. Further, this normative aspect claims that the adoption of marketing improves the democratic process. However, rational choice is an analytical ‘toolkit’ which does not seek to make normative claims. Indeed, normative arguments are inconsistent with rational choice, which seeks to provide a scientific, value-free approach to political analysis, and, consequently, the analytical and normative aspects of political marketing need to be rendered explicit and such normative aspects challenged.  相似文献

Past research has proposed various macrolevel theories of issue definition and agenda setting. However, we propose a microlevel theory of issue definition rooted in how individuals process information. We theorize that people process information about policy issues through a filter that emphasizes past assessments, ideology, background, social cues, and the continuing intrusion of new information. Most of these factors lead individual issue definitions toward stability. However, the introduction of an information signal of appropriate magnitude and character can produce punctuations in issue definition by individuals through time. Since the macrolevel definition of an issue is a type of aggregation of individual definitions, understanding how individuals define issues becomes a precursor to understanding issue definition at the system level. In evaluating the theory, we develop and evaluate a survey to study the issue definition process for individuals across multiple issues, and for global warming specifically. The survey also includes two embedded experiments to demonstrate the potential for punctuation in the issue-definition process for individuals and the system.  相似文献
