Public preferences about the availability of abortion under various circumstances have remained fairly stable over time. Yet a standard CBS/New York Times abortion question indicates that a significant shift in opinion occurred during the 1980s, whereby the public became increasingly supportive of legalized abortion as it is now. These very different patterns of public opinion about abortion suggest that the public perceived a shift in the abortion status quo, toward more restricted access, over time, and became more supportive of current abortion policy.A model of support for legalized abortion as it is now is developed that incorporates the influences of court activities and interest-group behavior. The analysis indicates that the public reacted directly to the activities of the courts, becoming more supportive of current abortion policy in response to media coverage of court cases that challenged the abortion status quo and Supreme Court nominations and confirmations. Although absolute preferences remained largely unchanged, it appears the public perceived an increasing threat to the status quo and became correspondingly less enamored with further restrictions on the availability of abortion.  相似文献

In this paper a new economic approach to standardization has been presented. Standardization has been regarded as a problem ofgradual choice. An individual chooses to apply more or less standards within a hierarchy of standards. With this decomposition of standards, the problem of strategic market power becomes less important than in the traditional models of standardization. It becomes possible to analyze the problems of network externalities within a framework of non-strategic behavior and to apply the tools of the traditional theory of externalities and public goods. While decentralized action may lead to too little standardization, committees may overcome this deficiency to some extent, but bureaucracies are likely to lead to overstandardization. In the empirical section of the paper it has been shown that our approach can be applied to the standard-setting process in languages, railroads, and telecommunications. In all three cases the tendency of bureaucracies to generate more standardization than committees has been corroborated.The authors are indebted for helpful comments to the participants of the Berlin Seminar on Political Economy and of the colloquium Algemene Economie, Rijksuniversiteit Groningen, and to A.

A typical assumption of electoral models of party competition is that parties adopt policy positions so as to maximize expected vote share. Here we use Euro-barometer survey data and European elite-study data from 1979 for the Netherlands and Germany to construct a stochastic model of voter response, based on multinomial probit estimation. For each of these countries, we estimate a pure spatial electoral voting model and a joint spatial model. The latter model also includes individual voter and demographic characteristics. The pure spatial models for the two countries quite accurately described the electoral response as a stochastic function of party positions. We use these models to perform a thought experiment so as to estimate the expected vote maximizing party positions. We go on to propose a model of internal party decision-making based both on pre-election electoral estimation and post-election coalition bargaining. This model suggests why the various parties in the period in question did not adopt vote maximizing positions. We argue that maximizing expected vote will not, in general, be a rational party strategy in multiparty political systems which are based on proportional representation.  相似文献

Building computerized information systems in weak African bureaucracies is a formidable task. Information systems often succumb to organizational constraints and either fail or underperform. This article examines why and provides a model of how they can succeed. The thesis is that African bureaucracy and, surprisingly, information systems development are contingent structures and processes. Given the right combination of government reformers (saints) and appropriate technical assistance specialists (wizards), the personal and contingent nature of African bureaucracies can facilitate the rapid introduction of information technology reform. The difficult task is to sustain the reform in a context where government staff are apathetic or even hostile to the reform (demons). An information system is sustained when it is insulated—its output is revered and tampering is feared. In African bureaucracies, information systems fail or underperform more often than they succeed, because the saints are few, the demons are many, the wizards are inappropriate, the systems are complex and the organizations are weak. The article concludes by reviewing five conundra of systems development in African bureaucracies: building systems without saints, managing demons, compartmentalizing systems, integrating system compartments and insulating systems. © 1998 John Wiley & Sons, Ltd.  相似文献

This article explores the implementation of SOE reform in China at the local level, using case studies in Guangzhou as illustration. It is argued that local government spearheads a reform agenda that puts locally-defined state objectives first, not necessarily favouring enterprise restructuring. A full-fledged negotiation model does not exist in SOE reforms because all enterprises are controlled by the state and have to comply with top-down policies and orders. Government-enterprise relations and the degree of entrepreneurial power depend largely on the economic strength of the enterprise, with the boomers getting a good economic bargain while the laggards fail to gain sympathy from government. Enterprise workers are largely at the mercy of restructuring decisions that come from bargaining and at times collusion between managers and local bureaucrats.  相似文献

North Korea’s foreign policy track record in the post-cold war era is mixed. Most notable setbacks are the diplomatic normalization between the Soviet Union (now Russia) and South Korea; the reversal of its UN policy that paved the way for the simultaneous admission of the two Korean states to the world organization; and the diplomatic normalization between China and South Korea. On the credit side of Pyongyang’s diplomatic ledger are changes in its relations with Tokyo and Washington. While tangible results have yet to materialize, particularly in North Korea-Japan relations, the groundwork has nonetheless been laid for significant improvement. North Korea’s suspected nuclear weapons development program has played a major role in the unfolding of its relations with the United States. Conceptually, North Korean foreign policy can be explained in terms of its quest for three interrelated goals: security, legitimacy, and development. In the post-cold war era security appears to have emerged as the most important of the three goals. North Korea is at a crossroads. The choices it makes in foreign policy will determine not only the direction of its domestic policy but, ultimately, the survival of the regime itself. The external players in Seoul, Washington, Tokyo, Beijing, Moscow, and Vienna (the IAEA) have varying degrees of leverage over Pyongyang’s policy as well.  相似文献
