Abstract: The effects of the Electronic Lodgment Service on relations between tax agents and the Australian Taxation Office provide evidence for both the value and limitations of integrating information technology innovation with regulatory reform strategy. IT innovations such as ELS can promote cooperative regulation. The limitations of this achievement are largely limitations of regulatory context and strategy.  相似文献

This article describes the findings of a program of research exploring the cognitive and behavioral consequences of passionate concern about government policy issues. American citizens vary a great deal in terms of the personal importance they attach to their attitudes on particular policy issues. Citizens whose policy attitudes are especially important to them are likely to think frequently about those attitudes, to perceive competing candidates as being relatively polarized on the issue, and to form presidential candidate preferences on the basis of those attitudes. Also, policy attitudes that citizens consider personally important are highly resistant to change and are therefore especially stable over long periods of time. The American public appears to be structured into many small issue publics, each composed of citizens who are passionately concerned about a single issue. Most Americans fall into very few issue publics, the particular ones being determined by each individual's unique self-interests, social identifications, and cherished values. The implications of these findings for the workings of democracies are discussed.  相似文献

This paper attempted to demonstrate that a rational voter model as derived by Barzel and Silberberg (1973) can be used (with modifications) to explain third party voting in presidential elections. The empirical findings strongly suggest that the rational voter model is applicable in explaining third party voting. This conclusion likewise suggests that people who vote for third parties do so under similar motivations as people who vote for the major parties. Thus, people do not appear to regard votes for third parties as wasted votes or engage in the voting process in an irrational fashion. Lastly, votes for third parties represent the transmission of individual preferences by people who believe that their vote is important and that in the aggregate their signal may be interpreted as a signal to alter the direction of current policies as run by the major parties. Therefore, it does not appear from the evidence presented here that we should distinguish between or treat differently voting participation for the major parties versus the minor or third parties in presidential elections.The author expresses appreciation to Charles Campbell, Gary Pecquet, Paul W. Grimes, and James E. McClure for comments and criticisms. The usual caveat applies.  相似文献

Political influence by a professional association, like the influence of any special interest group, is a collective good for the members of the profession. This paper investigates the variables affecting the ability of state optometric associations to overcome the free rider problem and induce optometrists to join the association. Although the empirical results show little evidence that organization costs are reduced by concentration in urban areas, the results do strongly support the hypothesis that there will be less free riding in smaller groups. The results also support the hypothesis that selective incentives enable latent groups to overcome the free rider problem. By providing continuing education at reduced fees to members of the association, optometric associations have increased the percentage of optometrists who are association members in those states with statutory continuing education requirements.  相似文献

This study examines the roles of the executive budgetary proposal, the executive veto, the legislative override, and legislative uncertainty about the executive's preferences in determining the outcome of a budgetary process. A sequential model of the budgetary process with three institutional agents — a legislature, an appropriations committee, and an executive — is presented. To focus attention on the executive proposal, the veto, the override provision, and uncertainty, simplifying assumptions are made: (1) the appropriations committee has monopoly agenda power, and (2) there is a closed amendment control rule. In order to characterize sequential equilibria of various combinations of veto rules and override provisions, we examine a particular arrangement of agents' preferences and a two item budget. The results demonstrate that the final budget depends critically on the executive proposal, the executive veto rule, the override provision, and the uncertainty. We achieve three striking results. First, the executive proposal may be effective in reducing the frequency of the exercised veto. Second, for a given override provision, a movement from the item veto to the item reduction veto leaves the executive worse off in some cases. Third, with the same change in institutions, the government budget may increase.  相似文献

Using data on all final National Priorities List (NPL) sites, this study employs an integrated model of distributive and public interest politics to determine whether the overall pace of cleanup efforts and funding of the 8.5 billion Superfund program over the past eight years reflects self-interested congressional influence or public interest objectives. Despite the fact that both EPA and Congress have substantial incentives to promote the Superfund program, the results indicate that once a site is on the final NPL, there is little committee-based congressional influence over the distribution of site cleanup or funding, although evidence exists that legislators can hasten a site's transition from proposed to final status on the NPL. The chief determinants of cleanup pace and level of funding are the site's Hazard Ranking System (HRS) scores, whether federal funds are financing the cleanup, and whether the site is designated as a state priority.  相似文献
