The political feasibility of protectionist policies that regulate international industry derives from the absence of overt collusion among domestic import-competing producers. The regulation of international industry cannot be explicit since governments would thereby be perceived to be approving (or instigating) international collusion. Hence, voluntary export restraints have been popularly presented with a focus on the difficulties confronted by domestic import-competing producers and a de-emphasis on the mutual gains to domestic and foreign producers from monitoring by a foreign government of a restrictive export cartel arrangement. Similarly, trigger-price mechanisms have popularly been explained in terms of the need for anti-dumping measures to preserve fair competition. Likewise, the involuntary export tax derived in the first instance from an administratively validated (but, as demonstrated by Kalt's econometric analysis, contentious) complaint of unfair foreign competition. Voluntary export restraints, trigger-price mechanisms, and involuntary export taxes are however protectionist devices, the beneficiaries of which can transcend national jurisdictions, and which have in common the characteristic that the gains to domestic industry interests derive from the regulation of foreign competitors.A previous version of this paper was presented at a conference on Economics and Power organized by the FWS Institute of Zug and held at Interlaken, Switzerland in July 1988.  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 usual caveats apply. The views expressed herein are solely those of the authors and should not be taken to represent the views of their employers.  相似文献

An increase in birth rates to Minneapolis minors following the enactment of a parental notification law was examined. A well-publicized link between increasing birth rates and the law is shown to have been premature. Birth, abortion, and population data by age, race, and region suggest that the increasing birth rate in Minneapolis was not related to parental notification, but rather to a growing racial minority population.Preparation of this article was supported in part by an Aldeen Grant from Wheaton College. The authors wish to thank the Minnesota Center for Health Statistics, particularly James Wigginton and Carol Vargas, for their considerable work to provide birth, abortion, and population data in a form suitable for the current analysis. The authors also thank Americans United for Life for purchasing the data and providing them to the authors.  相似文献

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

Australia's history as a settler colony within the British Empire fundamentally shapes its sense of security within the Indo-Pacific region. Australia has consistently looked outside of its region for security and sought partners on the explicit basis of political, cultural, and ethnic similarity. What role does Australia's history play in shaping its foreign policy? We argue that these choices in foreign policy are inextricable from Australia's history as a settler colony on the farthest reaches of the British Empire. The AUKUS Agreement (AUKUS) is an example of how Australia operates to preserve racial hegemony in the face of non-white threat — real or perceived. This research utilises critical discourse analysis to interrogate elite-level discourse around AUKUS to ascertain the dominant narratives that inform its creation, the issues it seeks to address in Australian security policy, how it is structured by historical narratives of security, and how it functions to structure those narratives going forward. This article seeks to participate in the growing push to decolonise International Relations by illuminating the way Australia is ontologically and epistemologically invested in the preservation of racial hegemony.  相似文献
