Although the framers of the U.S. Constitution agreed that thefirst principles stated by the Declaration of Independence werefundamental, they thought that the form which freedom shouldtake within the Constitution could not be discovered by a resortto natural rights (and thus declined to affix a bill of rightsto the Constitution). They rejected both the view that libertyis independence (whether of individuals or of states) and theview that liberty is equivalent to the rule of the people. Instead,they held a political view of freedom in which liberty is understoodas the scope men have for political action. The institutionsthey designed direct the use of liberty to the common good.In light of this analysis, the issue of whether the Constitution'sprovisions concerning slavery and its treatment of women areindications of an inadequate view of liberty can be answeredin the negative. 相似文献

Cost control commissions provide two primary types of recommendations: widespread benefits-widespread costs and widespread benefits-narrow costs. Both types of recommendations are not of the form predicted by the standard economic models of political behavior. The paper explores why governors sanction these commissions and the types of recommendations governors will accept. Legislators use the maxim of concentrate benefits-spread costs to maximize votes. Governors, however, face a lower return to concentrated benefit policies and a lower cost from concentrated cost policies. This leads a governor to favor at the margin, policies which have widespread benefit-widespread cost or widespread benefit-concentrated cost. Evidence from 5 state cost control commissions support the difference between the politicians. The cost control commissions sanctioned by governors have proposed recommendations of the widespread benefit-widespread cost and widespread benefit-concentrated cost form. Governors accepted approximately two-thirds of the widespread benefit-concentrated cost proposals, although they were more likely to accept recommendations of the widespread benefit-widespread cost nature. Recommendations which required legislative approval saw a lower likelihood of acceptance. This is consistent with the view that legislators prefer concentrated to widespread benefit recommendations. qu][The politician's] favorite strategy is to create a commission to study a problem and make recommendations that may then be used as political cover. Call it government by commission. 相似文献

Voter turnout in the United States is much lower than in almost all other democratic countries. This has been interpreted as a symptom of popular alienation from the political system, suspicion of politicians, and pessimism about the consequences of political activity. When these perspectives are measured directly, however, it is clear that Americans score very low on almost every item. Indeed, there is no relationship between political con- tentment and turnout. Turnout does not reflect international variations in acceptance of politicians or the political system. Rather, it responds to variations in the bureaucratic steps required to cast a ballot. The United States is one of a handful of countries that require a separate step–registra- tion–before the citizen can vote; and with the partial exception of France it is the only country in which the individual rather than the state bears the responsibility for registration. 相似文献

In principle, reporting by state and local governments to thefederal government is essential to the design and implementationof national policy. In practice, reporting often engenders resentmentof federal intrusion and is often dismissed as a waste of stateand local resources. Is reporting useless? Does it strengthenthe federal government at the expense of state and local governments?We asked federal, state, local, and site officials about thevalue and burden of five specific reporting systems in elementaryand secondary education. Common assumptions about reportingdid not correspond to respondent reactions. Both value and burdencascade through the intergovernmental system, reaching policymakersin all governments. Although critics seldom discriminate betweentypes of reporting, we found that reporting designed to improvecompliance with federal standards evoked different judgmentsof value and burden than reporting designed for assistance.These results suggest some new approaches to federal policygoverning the collection of information and to the design ofindividual reporting systems. 相似文献

This attempt to classify Social Security beneficiaries by type of benefit using the new Survey of Income and Program Participation (SIPP) has yielded promising results. Evaluations of the classification algorithm based on comparison of the estimated number of beneficiaries in each of the several categories to independent estimates of the number of beneficiaries indicate that in most instances a high percentage of each category has been identified. For the most part, age and monthly benefit amount size distributions seem reasonable. Furthermore, very few persons in the sample who were identified as Social Security beneficiaries could not be assigned to one or another of the benefit groups. The classification procedure also represents a marked improvement over earlier efforts to classify type of beneficiary that relied on data from the March Supplement to the Current Population Survey (CPS). Most importantly, the benefit classification scheme based on SIPP data appears to provide reasonably reliable distinctions between retired-worker and widow benefits for widowed women and permits the identification of retired-worker benefits for those women dually entitled to retired-worker and spouse benefits. In addition, the distinction between disabled- and retired-worker benefits for recipients aged 62-64 appears to be reasonably reliable, and for women under age 65, the classification procedure distinguishes between disabled-worker benefits on the one hand and widow and widowed mother benefits on the other. Finally, SIPP procedures for identifying minor child beneficiaries yield markedly better estimates than those available from the Current Population Survey. These improvements in the SIPP context are due entirely to the presence of information not collected in the CPS. The enhancement of the SIPP data set in turn resulted directly from an assessment of earlier work carried out by Projector and Bretz in the CPS context and on extensive research into the nature of Social Security reporting errors in the CPS. The superiority of the SIPP data set is linked principally to the presence of three pieces of information: the Medicare BIC, the direct question on reasons for benefit receipt asked of persons under age 65, and the direct measurement of recipiency and amount of benefits for minor children. Other items of some import include self-reported work disability, retirement status (ever retired from a job), previous marital status for currently married women, age first prevented from working due to a health condition, and Supplemental Security Income misreporting items.(ABSTRACT TRUNCATED AT 400 WORDS) 相似文献

Much public discussion about health care assumes, explicitly or implicitly, that only by denial of potentially beneficial care (called "rationing") can cost containment be achieved. This piece critically examines the various current usages of "rationing," and argues that it is being misapplied. Fur- ther, the call for rationing may be deflecting us from fruitful exploration of non-rationing alternatives to cost control. Two of these are briefly sketched as examples: physician fee controls and practice guidelines. 相似文献

Judicial decisions are one element in the erosion of local government budgetary discretion. For example, litigation concerning constitutional rights forces local government officials to allocate resources toward the rights-based population. While rights-based allocation decisions may narrow the budgetary discretion of public officials, some managers may, paradoxically, be "better-off"—defined as the ability to protect and defend their budgets — when discretion is reduced. This thesis is tested through a case study of jail overcrowding litigation in a county government. 相似文献
