Recent highly publicized traffic accidents involving older drivers have led to renewed interest in state policies and administrative practices that award and renew drivers’ licenses in the American states. Because the probability of traffic accidents is linked to the medical conditions that are more prevalent among the elderly, and because the number of older drivers is expected to rise over the next several decades, one might expect that this will be an increasingly important policy issue. This article discusses variations that are observed across states in law and administrative practice. A longitudinal analysis of data on crashes involving elderly drivers in fifteen states indicates that crash rates are directly related to the length of the renewal cycle for older drivers and inversely related to the stringency of testing at renewal. It is also likely that states requiring physicians to report conditions that would impair driving will experience lower crash rates. A secondary analysis of policy impacts on the licensing rates is not conclusive, a finding that is attributable to inaccuracies in the reported numbers of licensed drivers.  相似文献

Private sector provision of public infrastructure in Australia at all levels of government, including local government, has steadily increased over the past twenty years. Nevertheless, this method of providing public infrastructure remains controversial. This article seeks to provide a critical review of the arguments surrounding private sector provision of infrastructure in Australian local government. It examines both the case for private sector provision of municipal infrastructure in Australia and the major arguments advanced against this approach to infrastructure development. Given the conceptual argumentation and empirical evidence on private municipal infrastructure provision, it is argued that policy makers should employ a nuanced performance evaluation framework to assess the benefits and weaknesses of private provision on the basis of the specific type of infrastructure in question and the kind of services it provides rather than simply endorse carte blanche privatization.  相似文献

The gender gap has been an important feature of American elections since 1980. Yet, most explanations for the effects of gender on voting behavior focus on differences between men and women without taking account of how campaign strategies may serve to highlight or mask these differences. I examine how Senate candidates act strategically in deciding whether and how to target women voters. I find that candidates make these decisions based largely on two factors: (1) the importance of these issues to the state's voters and (2) whether gender gaps had been decisive in previous statewide contests. Analysis of exit-poll data indicates that when campaigns focused more on women's issues, women became more likely to vote Democratic while the vote choices of men were unaffected. Thus, campaign strategies do appear to influence the importance of gender differences in voting behavior.  相似文献

This paper investigates the impact of fiscal institutions on state government borrowing costs. We find that institutions have both a direct and indirect effect on interest costs paid by state governments. Revenue limits are associated directly with higher interest costs; expenditure limits, stricter balanced budget rules, and restrictions on state debt issuance are indirectly associated with lower interest costs because they lead to higher credit ratings. It appears that investors and bond raters incorporate information on fiscal institutions into their assessment of state government credit quality.  相似文献

Pollution liability and general liability insurance policies, in theory, should afford complementary rather than overlapping coverage. While this works well in theory, non-traditional pollution events challenge this outcome. This article focuses on loss events resulting from explosions, and in particular whether the resulting harms should be considered for coverage under a pollution policy or a general liability policy.  相似文献
