One of the most widely used method of targeting is to reduce welfare benefits as income rises. Although the need for such targeting is clear enough, it also entails two important difficulties. Firstly, the prospect for the recipients of losing part of their benefits if they were to earn more can be a deterrent to work harder. Secondly, by reducing the number of recipients, targeting reduces the political support for taxation and redistribution. The purpose of this paper is to study the voting equilibrium of the degree of targeting and the level of taxation in an economy where labour supply is variable. The analysis reveals that targeting may be fatal for redistribution even though it rejects strictly less than the richest half of the population, and that it is not possible for a coalition of the extremes to form and reject the middle income group from the welfare system. Moreover, because targeting affects labour supply, we find that Pareto improvements are possible when targeting is either “too low” or “too high”. We also find that voting simultaneously over taxation and targeting is favourable to the poor in the sense that they can converge to their most-preferred policy by successively forming a majority coalition with the rich to increase targeting and with the middle to increase taxation.  相似文献

This study examined the prevalence and correlates of sleep disturbance in adolescents. Two hundred seventy-seven 9th- and 10th-grade students completed a questionnaire on sleep quality, sleep habits, beliefs about sleep, and daytime mood and functioning. Based on their responses, subjects were classified as good sleepers (66%), occasional poor sleepers (23%), and chronic poor sleepers (11%). Occasional and chronic poor sleepers reported being significantly more depressed, without energy, tense, moody, and irritable and less rested and alert than good sleepers. They were also more likely to describe themselves negatively. However, poor sleepers were not consistently more tired than good sleepers. Rather, they tended to be least tired in the evening, the time when most good sleepers reported feeling tired. There were few differences in the sleep habits and beliefs about sleep of good and poor sleepers. All subjects reported shifts in bedtimes and waketimes from weekdays to weekends, with occasional and chronic poor sleepers showing a tendency toward greater shifts, a possible factor contributing to their sleep disturbance. Occasional and chronic poor sleepers also reported more observable behaviors and feelings of stress than good sleepers. The need for early intervention with particular attention to teaching adolescents about good sleep habits and the need for stable bedtimes and waketimes and the possibility of joint intervention on daytime stress and sleeping problems are discussed.  相似文献

Value added taxes (VATs) are important major revenue sources worldwide, yet keeping these taxes as easy to administer as possible is often overlooked. A poorly administered VAT raises less revenue than possible and can change the very nature of the tax, resulting in unintended economic distortions. This article analyzes the experience with the VAT in the Russian Federation and provides evidence that poor tax administration both contributed to the decline of VAT revenues beginning in 1993 and continues to hamper VAT revenue collection today. Administrative issues must not be ignored when implementing a consumption-based tax like the VAT.  相似文献

Data on voter turnout and choice at the Rwanda’s 2003 and 2015 constitutional referenda were acquired and analyzed. The results revealed contrasting changes in voter turnout between diaspora and in-country electorate. Arguably, at home, lack of freedom on the part of registered voters to make independent choices may explain the 9.3 percent and 5.2 percent increase in voter turnout and “yes” vote, respectively. On the other hand, while the repressive arm of the regime can reach Rwandan citizens both at home and abroad so as to compel them not oppose its political agenda, voters in diaspora enjoy some level of relaxation, especially those staying in Western democracies, which could explain the 37.8 percent drop in voter turnout. The article further argues that the results of the 2003 and 2015 referenda could be used to support suggestions that the Tutsi electorate indeed stands more divided than it was a decade ago.  相似文献

The rate for the sudden infant death syndrome (SIDS) in Cape Town, South Africa, is estimated to be among the highest in the world (3.41/1000 live births). In several of these areas, including those of extreme poverty, only sporadic, nonstandardized infant autopsy, and death scene investigation (DSI) occurred. In this report, we detail a feasibility project comprising 18 autopsied infants with sudden and unexpected death whose causes of death were adjudicated according to the 1991 NICHD definitions (SIDS, n = 7; known cause of death, n = 7; and unclassified, n = 4). We instituted a standardized autopsy and infant DSI through a collaborative effort of local forensic pathology officers and clinical providers. The high standard of forensic investigation met international standards, identified preventable disease, and allowed for incorporation of research. We conclude that an effective infant autopsy and DSI protocol can be established in areas with both high sudden unexpected infant death, and elsewhere.
