A well‐established strategy for evaluating alternative income distributions is based on the use of an abbreviated social welfare function that depends only on mean income and an inequality index. In keeping with this literature, we study the existence of social welfare functions that can be written as a trade‐off between efficiency and income polarization. This paper proposes a class of social welfare functions consistent with the Esteban and Ray, and Duclos, Esteban and Ray income polarization indices. For this result, we expand the domain for personal preferences to incorporate not only own income but also the well‐being of others. In addition, we link our proposal to the literature on relative satisfaction. The approach is illustrated by an empirical application using the CPS database for the United States in the period 1991–2010.  相似文献

最优所得税主要探讨税收如何兼顾公平与效率问题,以及给定公平偏好程度下,如何确定最优边际税率水平。即使在崇尚罗尔斯社会福利函数的社会里,政府同时兼顾再分配和财政收入目标的基础上,只要略加考虑税收对劳动供给的效应,哪怕是微弱的考虑和兼顾,最高边际税率都不会达到100%。而且,借鉴斯特恩最优线性所得税模型及美国个人所得税制度,估计我国现行个人所得税最高边际税率还可以适当降低到36%左右。  相似文献

This paper attempts to reconstruct and assess the intellectual itinerary of Hicks on the valuation of social income. His 1958 and 1981 papers on that topic have been wholly ignored in the economic literature. In both of them differentmeasures of real income are provided. These show to what extenteach one of them can be relied upon. Our assessment argues that it is impossible to measure social income independentlyof the reasons for which that measure is required and that any valuation cannot ultimatelybe made independently of political and ethical considerations.  相似文献

Axiomatic analysis of bankruptcy problems reveals three major principles: (i) proportionality (PRO), (ii) equal awards (EA), and (iii) equal losses (EL). However, most real life bankruptcy procedures implement only the proportionality principle. We construct a noncooperative investment game to explore whether the explanation lies in the alternative implications of these principles on investment behavior. Our results are as follows (i) EL always induces higher total investment than PRO which in turn induces higher total investment than EA; (ii) PRO always induces higher egalitarian social welfare than both EA and EL in interior equilibria; (iii) PRO induces higher utilitarian social welfare than EL in interior equilibria but its relation to EA depends on the parameter values (however, a numerical analysis shows that on a large part of the parameter space, PRO induces higher utilitarian social welfare than EA).  相似文献

在现代化进程中,农村社会保障始终处于整个社会保障体系的边缘,农民长期游离于社会保障网络之外。改革的实践和理论都未能突破城市和农村两个独立的圈子,这造成了农村社会保障制度建设严重滞后的状况。建立农村社会保障制度必然要付出巨大的成本,包括推行成本和社会保障费用支出成本。但建立农村社会保障制度带来的社会效益也是非常明显,是难以用数据来衡量的。  相似文献

In this article, we explore the historical evolution of social welfare policy in sub‐Saharan Africa focusing on the post‐1900 period. We show that we have seen a very conflicted approach to social development. Social security was reluctantly and very slowly introduced during the colonial period, and the post‐colonial state has likewise been cautious in its approach and has not been able to build a long‐term social contract with society. Instead, it has relied on clientelism, cooption, coercion and patronage. Since the late 1990s we have seen the African state and political systems begin to mature with greater democratisation and the growth of formal welfare systems.  相似文献

构建了一个土地对社会福利影响的分析模型,并用天津市的数据进行检验。研究结果表明:(1)政府对于土地供应量的控制减少了均衡资本量;(2)严格的土地政策会使单位资本产生的福利量减少;(3)土地政策的适时调整能使经济发展沿着社会福利最大化的路径发展。因此,土地政策的制定应该以社会需求为导向,并通过适时调整以实现社会福利最大化。  相似文献

Measuring Attitudes Towards Inequality   总被引:1,自引:0,他引:1  
Individuals' attitudes to inequality aversion are measured using survey data, based on the leaky-bucket experiment, for several groups of students in Australia and Israel. Three forms of social welfare function are estimated. It is found that measures of inequality aversion can be obtained with some precision and that these estimates are substantially lower than the values typically used by those measuring inequality and examining optimal tax structures. Furthermore, a welfare function based on the Gini inequality measure is generally found to give a better fit than forms based on constant relative or constant absolute inequality aversion.

固定资本投资是流动资本投资的前提和基础,也是整个社会经济规模扩张与发展所必须依赖的重要物质基础。现期厂商的固定资本投资会直接导致本期总需求的增加,在保持总供求平衡的前提下,政府本期的调控货币投放规模将会相应减小,从而影响本期社会弱势居民的福利水平。  相似文献

通过构建最优货币政策模型对中国货币政策进行的实证检验,发现中国的货币政策主要以盯住通货膨胀为主要目标,同时关注产出的变化,但对股票价格波动的变化并没有给予充分的关注。而通过中国预设货币政策操作框架下对股票价格波动不同反应状况的分析,发现货币政策对资产价格赋予较小权重时,中央银行的福利损失函数将会有所改善;如果继续加大对资产价格干预的权重,则会导致中央银行福利损失函数的迅速恶化。因此可以认为,中央银行还不适宜对资产价格进行过度的关注,只适合在关注通胀和产出的基础上,对资产价格给予适度的关注。  相似文献

Based on China Household Finance Survey (CHFS) data, China’s Gini Coefficient stood at 0.61 in 2010, above the global average of 0.44, according to the World Bank. The high Gini Coefficient represents a large income disparity of the country. It is understandable that a high Gini is common in fast-growing economies and can be reduced through government’s transfer payments given the experience of OECD countries. This paper illustrates the breakdown of China’s Gini, regional, rural and urban differences in household income. Specifically, it is found that poor health, insufficient social welfare and low education level are the main reasons for poverty of rural households. This paper also provides solutions to reduce the Gini coefficient. In the short term, China government can invest more on social insurance and implement large-scale transfer payments. The figure shows that China government has sufficient financial sources to strengthen secondary distribution to subsidize the low-income group. In the long term, government can increase overall educational level and reduce the opportunity inequality to narrow the income gap.  相似文献

通过构建破坏性创新企业与在位企业进行市场竞争的双寡头博弈模型,分析在具有不同收入分布特征市场中破坏性创新企业的市场绩效及社会福利。研究发现,在收入差距较大的市场中,破坏性创新企业获得更大的市场份额和利润,社会福利相对较小;相反,在收入水平较高且分布趋向同质的市场中,在位企业获得更大的市场份额和利润,并且,破坏性创新厂商的利润随着收入水平的提高而降低。同时,随着收入水平的提高,两企业的产品质量不断提高,但质量差距不断扩大,社会总福利也随之增加。最后,进一步阐释了破坏性创新更多地发生于贫富差距较大的新兴市场的微观机制,为企业根据不同市场的收入分布特征选择竞争战略提供理论依据,为相关国家基于收入分布特点制定限制或支持破坏性创新创业政策提供理论参考。  相似文献

In this paper, we provide a general equilibrium analysis of corporate profit tax on income distribution, unemployment, and wage inequality. With firm dynamics in industrial sector, we identify a new channel through which profit tax affects income and wage inequality: profit tax cut will widen not only the wage gap between skilled and unskilled labor, but also exacerbate the wage inequality of unskilled labor among different sectors. The welfare effect of profit tax cut depends on unemployment deepening (labor-distortion effect) and more manufacturing firms enter the market (business-creation effect), eroding the market share of incumbent firms (business-stealing effect).  相似文献

This paper considers the use of alternative welfare metrics in evaluations of income inequality in a multi‐period context. Using Norwegian longitudinal income data, it is found, as in many studies, that inequality is lower when each individual's annual average income is used as welfare metric, compared with the use of a single‐period accounting framework. However, this result does not necessarily hold when aversion to income fluctuations is introduced. Furthermore, when actual incomes are replaced by expected incomes (conditional on an initial period), using a model of income dynamics, higher values of inequality over longer periods are typically found, although comparisons depend on inequality and variability aversion parameters. The results are strongly influenced by the observed high degree of systematic regression toward the (geometric) mean, combined with a large extent of individual unexpected effects.  相似文献

本文致力于弄清三个方面的问题:(1)通过梳理在确定性和不确定性条件下理性偏好的最新研究成果,指出理性的边界,揭示主流经济学个体主义方法论的局限性。(2)通过考察阿罗不可能性定理的条件,提出阿罗不可能性定理的逆否命题,探索摆脱阿罗不可能性定理的途径和社会福利函数存在的条件。(3)根据阿罗不可能性定理,指出个体主义方法论在分析个人理性和集体理性、微观经济学和宏观经济学、个人效用和社会福利之间的关系时遭遇的困难,进而提出用整体主义方法论解决此类问题的思路。本文认为,制度和规则是社会的灵魂,在规则的语境下新古典经济学和制度经济学不是对立而是互补的。  相似文献

This paper extends an example due to Samuelson (1974) to develop the relationship between possible compensated complementarity between two goods and the two elasticities of substitution in an extended three good CES utility function. It also uses the same utility function to develop the implications of a generalized income share parameter and two different relative prices for possible complementarity between goods. Finally, it explores possible complementarity in a more general utility function with non-constant elasticities of substitution.  相似文献

收入差距、位置消费与社会稳定   总被引:2,自引:1,他引:2  
适度、合理的收入差距,不仅是激励人们竞争,促进发展的重要务件,也是位置消费产生的基本条件;但过分悬殊的收入差距则不仅会影响人们的社会心理,不利于提高有效消费,而且可能产生畸形的位置消费行为,甚至会因此影响社会的稳定.在分析和研究目前收入分配问题时,应当从位置消费的新视角研究它们对社会稳定的影响.研究位置消费有利于我们从人们相互比较的满意度中观察改革的效果,权衡各项利弊得失,并及时地采取微调措施,尽可能地减少改革的摩擦和阻力.  相似文献

A social-welfare (illfare) function framework is applied to compare two demographic groups as to the severity of their unemployment experience. This is based on the assumption that for each individual the disutility of unemployment is an increasing and convex function of spell length. The very concept of spell length and its distribution, however, is not unambiguous. In contrast to previous literature which focuses exclusively on the interrupted spell length in a stock of unemployed, we stress the usefulness of the concept of complete spell length in a cohort of unemployed. We establish an equivalence relationship between second-degree dominance in the cohort and first-degree dominance in the stock. For specific illfare functions the disutilityU(x) when applied to the cohort and the disutilityU(x) when applied to the stock will produce the same value of aggregate welfare (illfare).  相似文献
