Testing the impact of financial inclusion on income convergence: Empirical evidence from Nigeria

Financial inclusion, as a key pillar for inclusive development, has long been considered as an important instrument for reducing poverty and income inequality. However, the income convergence effect of financial inclusion remains only partially explored. Using longitudinal data covering three survey waves on Nigerian households, this study explores the potential of financial inclusion as an instrument for reducing income disparity. After controlling for the endogeneity issues, the results of instrumental variable linear and quantile regressions consistently show a strong nexus between financial inclusion and per capita income. This positive effect is experienced by all households regardless of income distribution. The decomposition results reveal that ab initio, financial inclusion resulted in income divergence leading to widening inequality across the households with various income distributions. However, the income convergence started from the middle to the higher income household categories, with the lowest income lagging behind in the second wave. The lowest income households eventually converged in the data of the third wave. In this sense, it can be argued that financial inclusion could play an important role in the reduction of income inequality.     

Income inequality and access to housing: Evidence from China

Economic theory suggests that income inequality predicts housing price and housing affordability for low-income households. Employing Chinese urban household survey data, this paper examines empirically the relationship between income inequality and access to housing for urban low-income households. The empirical results demonstrate that higher income inequality within cities is significantly related to a higher housing cost burden, a smaller per capita living space, and lower housing quality for low-income households. Further studies demonstrate that the negative impacts of income inequality could be moderated by product differentiation in housing markets, as a higher degree of differentiation in the size of housing units corresponds to a smaller effect of income inequality on housing affordability.     

信贷约束下的农村金融与农村收入分配关系研究

文章建立了一个简单的两期生命周期模型来考察在信贷约束下农村金融与农村收入分配不平等的作用机制。模型结论表明,在存在农村信贷约束的情况下,农村金融的发展能否起到缩小农村居民贫富差距的作用,主要取决于农业投资回报率、农村金融贷款利率和农户进入农村金融市场的成本对比：在其他条件不变的情况下,受农村金融支持的农业投资回报率越高,农村金融贷款利率越低,农户进入农村金融市场的成本越低,则农村金融的发展越有利于缩小农村居民的贫富差距。     

中国开征碳税对价格、福利及公平影响的测度

本文利用投入产出和线性需求模型分析了碳税的价格影响、福利成本以及再分配效应。征税导致占中低收入居民支出比重较大的基本消费品价格大幅上涨,如电热水气、房屋、公共交通、食品等;从等价性变化、补偿性变化的角度看,城镇居民的福利损失随收入降低而上升,而农村居民中中等收入家庭损失最大;Atkinson公平指数显示碳税前后贫富差距有所扩大。因此,碳税具有一定累退性。但是,碳税边际福利成本及其收入差距影响并不大,因此政府可以通过转移支付手段缓解其负面冲击。     

农村公益性小额信贷现状研究——基于贫困户需求视角的分析

文章基于对山东省嘉祥县3个乡镇(卧龙山镇、大张楼镇、马村镇)小额信贷情况的农户调查数据,从需求视角出发,分析得出小额信贷需求的影响因素和贫困农户需求不足的原因。发现以扶贫为设计初衷的农村小额信贷项目实际参与对象已从中、低收入贫困户转向进行非农生产性经营的中等偏上收入户和高收入农户,并且生产性小额信贷资金多被农户用于消费性支出。最后,文章尝试提出了一些公益性小额信贷的新思路和新模式。     

Is income a good welfare indicator for Spanish households? A comparison between both distributions

This paper compares the income and welfare distributions of Spanish households, with the objective of determining whether the first is a good indicator of the second. We consider different inequality measures of both adjusted income and welfare. The results show that the income ranking does not represent the welfare ranking of households and, secondly, that monetary inequality is higher than welfare inequality, which gives support to the idea that leisure time has a compensating effect on household welfare.     

Political Control and Economic Inequality: Evidence from Chinese Cities

This paper explores the consequence of political control on intra-city economic inequality. Utilizing the unique political institution with mass cadre transfers and household survey data from 81 Chinese cities in 2010, 2012, and 2014, we find that cities with a “local” leader enjoy an almost 6% reduction in expenditure inequality, and the gap is especially narrowed in the lower income families. The reduction is attributed to larger amount of targeted transfers to low-income households. This paper is among the first to empirically support the argument supporting local residence duration for office holding in public sectors, and also contributes to understanding the political economy of social welfare programs as well as campaigns in inequality reduction.     

数字普惠金融的创业效应与收入不平等:数字鸿沟还是数字红利？

数字普惠金融与实体经济之间的关系受到学界广泛关注,但其究竟是普惠的数字红利还是金融领域的数字鸿沟,这是数字普惠金融快速发展中亟需回答的重要理论与现实问题。文章通过匹配宏观统计数据和微观调查数据,实证研究了数字普惠金融的发展对收入不平等的影响,并从创业效应这一渠道进行了机制分析。研究发现：数字普惠金融的发展总体上改善了收入不平等状况,而数字普惠金融的创业效应是影响收入不平等的重要渠道之一。进一步的中介效应分析表明,数字普惠金融的创业效应对收入不平等的影响存在异质性：数字普惠金融通过促进生存型创业从而改善了收入不平等,而数字普惠金融对机会型创业的促进却在一定程度上扩大了收入不平等。文章的研究结论对于理解数字普惠金融发展的正外部性以及如何缓解收入不平等提供了新的视角。     

The Influence of Demographics and Household-Specific Price Indices on Consumption-Based Inequality and Welfare: A Comparison of Spain and the United States

Previous research has suggested that inequality is lower in Spain than in the United States when it is based on income. For the present article, both inequality and social welfare are examined, with household consumption expenditures used as a proxy for household welfare. For tractability, equivalence scales depended only on the number of people in the household. Household-specific price indices were used to express the 1990-1991 expenditure distributions in 1981 and 1991 winter prices. Our results reveal that inequality and welfare comparisons are drastically different for smaller and larger households. When all households are considered, the two-country comparison suggests that the income inequality ranking can only be maintained for expenditure distributions when economies of scale are small or nonexistent. However, welfare is always higher in the United States than in Spain. Because inflation during the 1980s in both countries was essentially distributionally neutral, all results appear to be robust to the choice of time period.     

Efficiency or equity? The effect of an exogenous agricultural commercial shock: Evidence from Manchuria in the 1930s

The adoption of high-value cash crops (HVCs) is considered an efficient way to improve farmers' productivity and welfare, although the systematic empirical evidence is limited. By exploiting an exogenous commercial shock for soybeans and microlevel rural survey data from Manchuria of China in the 1930s, where factor markets were relatively well functioning, this study investigates the influence of HVC cultivation on farmers' agricultural performance, welfare, and inequality both theoretically and empirically. We find that (i) larger farms devote a larger proportion of land to HVCs and that (ii) farmers who cultivate a larger proportion of HVCs have higher agricultural productivity, profit, net income, and expenditure. Furthermore, the adoption of HVCs lowers profit, income, and expenditure inequality by enhancing income from wages relative to land rents, which benefits households with less land.     

E-commerce and Consumption Inequality in China

Consumption inequality may impede economic development and hinder the achievement of common prosperity. Using three waves of the China Family Panel Studies from 2014 to 2018, this paper investigated the impact of e-commerce on consumption inequality, as measured by the Kakwani index. The results indicate that e-commerce can reduce household consumption inequality. A mechanism analysis shows that e-commerce can narrow household income inequality, increase the purchasing power of low-income households, and promote the consumption of households with limited access to offline markets, thereby reducing the consumption gap. A heterogeneity analysis suggests that the positive role of e-commerce in reducing consumption inequality can be more significant among vulnerable households, such as households with elderly members and less-educated households. E-commerce can have varying impacts on consumption inequality across different subcategories of household expenditure, with the greatest impact seen in entertainment and education expenditure. These findings provide new evidence for the role of e-commerce in reducing consumption inequality in the digital economy, and the implications of this are discussed.     

Estimating flexible consumption functions for urban and rural households in China

There are few comprehensive studies of household consumption in China that covers all commodities due to data restrictions. This prevents the calculation of inequality indices based on consumption. This lack of coverage also makes analysis of policies that affect consumption difficult; economy-wide models used for analysis often have to employ simple consumption forms with unit income elasticities. We estimate a translog demand system distinguished by demographic characteristics, giving price and income elasticities that should be useful for policy analysis. We estimate separate functions for urban and rural households using household expenditure data and detailed commodity prices (1995–2006). This allows future analysis of social welfare and inequality based on consumption to supplement existing studies based on income. To illustrate an application of the model, we project consumption composition based on projected prices, incomes and demographic changes – aging, education improvement and urbanization.     

人口老龄化对城乡收入不平等的影响效应研究——基于中国二元经济结构演变的视角

理论分析表明,二元经济结构下人口老龄化能够通过要素禀赋结构调整和社会福利改善对城乡居民收入产生不同的收入效应和替代效应,进而影响城乡收入不平等。利用中国2000-2014年省际面板数据进行实证检验发现：中国人口老龄化显著的扩大了城乡收入不平等,但要素禀赋结构和社会福利水平对老龄化条件下的城乡收入不平等影响效应不同;随着对老年人口供养负担的加重,社会福利支出对老龄化条件下的城乡收入不平等主要表现为替代效应,城市偏向的社会福利支出使得农村因照料老人引起的劳动力供给减少扩大了城乡收入不平等;而要素禀赋结构的转变则使得老龄化主要表现为收入效应,劳动力相对资本的稀缺性导致转移劳动力工资上涨,从而缩小了城乡收入不平等;随着老龄化深化,通过社会福利改善和要素禀赋结构调整能够有效抵消老龄化对城乡收入不平等的负面影响;研究也证实了二元经济结构的优化和农业规模化经营对城乡收入不平等的缩小作用,而失业率上升和城乡投资差距却会加剧城乡收入不平等。     

减税降费有助于缩小中国家庭经济不平等吗——来自2011年个税改革的证据

共同富裕要求我们从多维视角审视物质层面的不平等，在当前减税降费的大背景下，个人所得税是调控收入分配的关键手段。文章从收入、消费和财产所构成的多维经济不平等视角出发，对2011年个人所得税改革调节家庭经济不平等的效应进行了探讨。研究发现：个人所得税改革的公平效应是显著的，使经济不平等程度下降了13.64%，其中对城市地区的调节效应更强，对低福利阶层和高福利阶层的影响相对显著。在作用机制方面，个人所得税改革主要影响收入不平等，并进一步作用于消费不平等和财产不平等，最终影响经济不平等。为充分发挥个人所得税的调节效应，应逐步提高个人所得税比重，补充和细化专项附加扣除项目与标准，逐步以家庭为基础征收个税。     

金融普惠可以提高减贫质量吗?——基于多维贫困的分析

切实提高减贫质量对我国打赢打好脱贫攻坚战和守住脱贫成果至关重要。金融普惠作为当前我国金融改革和脱贫攻坚的重要举措,是否有助于提高减贫质量仍是有待回答的问题。文章基于中国家庭金融调查2015年数据,从多维贫困和多维贫困脆弱性两方面出发研究了金融普惠对我国农村减贫质量的影响。研究发现,金融普惠可以同时降低农村家庭多维贫困和多维贫困脆弱性,并且对多维贫困问题严重的农村家庭有更大的作用;区分不同贫困和不同金融服务发现,金融普惠可以显著降低收入贫困、教育贫困及生活质量贫困,对健康贫困的影响则不显著;银行营业网点与金融服务点渗透、以及储蓄、贷款、保险及数字金融服务使用可以提高减贫质量,而其他金融机构渗透、信用卡使用及银行服务评价的作用相对有限。进一步地,文章研究了金融普惠减贫质量效应的环境条件,发现村庄市场及制度环境和家庭需求环境改善有助于充分发挥金融普惠的积极作用,相反则可能构成一定的制约。最后,文章检验了金融普惠的影响机制,发现促进农村家庭人力与物质资本积累、以及地区经济发展等在其中发挥了重要的中介作用。文章结论为我国提高减贫质量提供了可靠的政策工具,同时也可促进我国全面建成小康社会和经济实现高质量发展。     

The long-term evolution of national income inequality and rural poverty in China

Using the five waves of the China Household Income Project surveys conducted during 1988–2013, we investigate long-term changes in national income inequality and rural poverty in China. National income inequality rose markedly to 2007 and thereafter fell slightly. Income growth was widely shared, but inequality increased because the high-income percentiles had faster income growth than lower percentiles and because the gap between urban and rural household incomes widened. The fall in income inequality after 2007 reflects faster income growth among low-income percentiles and the impacts of newly introduced redistributive policies. The paper also finds a considerable, ongoing poverty reduction in rural China. A poverty decomposition analysis indicates that this rural poverty reduction was mostly due to income growth rather than redistribution.     

Debt and household finance: evidence from the Financial Diaries

The Financial Diaries data-set is a unique, new set of year-long daily income, expense and financial transactions for households from three different areas of South Africa. These data show that over-indebted households (those that spend 20 per cent or more of their gross monthly income on debt) do not fit one homogeneous profile. Formal debt tends to be responsible for over-indebtedness in the urban areas, while in the rural areas the cause tends to be informal debt. In the urban areas high indebtedness is more prevalent among medium-income and high-income households, whereas in the rural areas it occurs at all income levels. High indebtedness in grant-dependent rural households tends to be persistent, whereas in wage-dependent urban households it is often short-lived. These findings present a new financial picture of poor rural populations that is unlikely to be touched by recent policy measures to address over-indebtedness.     

Does Financial Intermediation Development Increase Per Capita Income in Rural China？

This paper investigates the impacts of financial intermediary （or banking） development on village-level per capita income using a Chinese dataset for selected years between 1993 and 2006. The empirical results from a random effect regression model indicate that mean per capita income in rural villages follows an inverted U-shaped path as financial intermediation develops. However, using a pooled quantile regression approach, we find that median per capita income in rural villages follows a positive linear path, rather than an inverted U-shaped path, as financial intermediation develops. The positive linear effect of financial intermediary development is observed at the lower and higher ends of the conditional per capita income distribution. This suggests that development of financial intermediation in China might not have statistically significant differential effects in low-income or high-income rural villages.     

中国开征碳税对价格、福利及公平影响的测度

本文利用投入产出和线性需求模型分析了碳税的价格影响、福利成本、以及再分配效应。征税导致占中低收入居民支出比重较大的基本消费品价格大幅上涨,如电热水气、房屋、公共交通、食品等;从等价性变化、补偿性变化的角度看,城镇居民的福利损失随收入降低而上升,而农村居民中中等收入家庭损失最大;Atkinson公平指数显示碳税前后贫富差距有所扩大。因此,碳税具有一定累退性。但是,碳税边际福利成本及其收入差距影响并不大,因此政府可以通过转移支付手段缓解其负面冲击。     

Financial Restraints in a Mature Welfare State--The Case of Denmark

The Scandinavian welfare states are mature in the sense of havinga high level of standards for public provisions of welfare servicesas well as a high replacement level for income transfers, especiallyfor low-income groups. In this welfare model, individuals havebasic rights to welfare services and social transfers independentlyof their ability to pay, their labour-market history, etc. Thefinancial viability of the model relies on a high tax burdenand a high level of labour-force participation for males andfemales. Evaluated on the basis of international comparisonsof income levels and inequality, the model has performed well.In a forward-looking perspective, however, the welfare modelfaces problems that may put the financial viability of the modelat risk. Two important challenges are demographic changes andthe so-called growth dilemma (increased demand for servicesand leisure). We discuss these issues using Denmark as an exampleand argue that while these two challenges may be of the sameorder of magnitude, it is easier to propose solutions to thedemographic challenges than to the growth dilemma which areconsistent with the basic principles of the welfare state.
