Does decentralization reduce income inequality? Only in rich states

We investigate the relationship between fiscal decentralization and income inequality using data from U.S. states over three and a half decades. Our study contributes to the literature in several ways in terms of empirical methodology and specification. First, we take into account integration and cointegration properties of the data and estimate the cointegrating relationship between fiscal decentralization and income inequality using Fully Modified Ordinary Least Squares, following Pedroni (2000). Second, we investigate the direction of the causality. Finally, and perhaps most importantly, we investigate if the relationship between fiscal decentralization and income inequality is conditional on income in each state. We find that fiscal decentralization does reduce income inequality, but only in rich states. We also find that causality runs from fiscal decentralization to income inequality, not the other way around.     

Economic growth and income inequality in the Asia-Pacific region: A comparative study of China,Japan, South Korea,and the United States

This paper builds an inequality-growth-redistribution nexus, and applies the Engle–Granger two-step ECM approach to estimate the long-run and short-run relationships between inequality and growth for four economies: China, Japan, South Korea, and the United States. Our estimation results support the S-shaped curve hypothesis relating GDP per capita to inequality with different starting points for the four economies. For the reverse relationship, we find a positive causal relationship for China, Japan, and the United States, indicating that increased income inequality spurred economic growth. In addition, we find mixed results on the effect of trade openness on inequality and growth. Trade openness reduced inequality in the United States and Japan, worsened it in China and had no significant effect in South Korea. In the inequality-GDP per capita relationship, exports provided an impetus to economic growth for Japan. As for redistribution, although fiscal redistributive measures reduced inequality in Japan, they played no major role in the other three countries. With regard to the inequality-GDP per capita relationship, all countries except for China show a negative effect of fiscal redistribution on GDP per capita.

政府财政政策对经济增长的影响——基于一个资本积累与创新相互作用模型的分析

政府财政政策对经济增长和社会福利的影响,是经济增长理论和宏观公共财政理论研究的重点,已经有大量的研究。本文在一个资本积累与创新相互作用的框架下内生化劳动力供给,假设政府通过征收平滑的收入税为公共支出融资,并且将政府公共支出区分为资本性支出和研发性支出,从而考察了税收和财政支出结构对经济增长的影响及其作用机制。研究发现,当政府通过征收收入税为生产性公共支出融资时,收入税税率与经济增长率之间存在一个倒U形的关系,从而回到了Barro(1990)的结论,尽管本文强调的政府财政政策作用于经济增长的机制与Barro(1990)差别较大;在基准经济(benchmark economy)的参数环境下,财政支出结构与经济增长率之间存在一个倒U型关系,从而经济中存在一个最优的财政支出结构。     

Asia's quest for inclusive growth revisited

Despite the rapid economic growth and poverty reduction, inequality in Asia worsened during the last two decades. We focus on the determinants of growth inclusiveness and suggest options for reform. A cross-country empirical analysis suggests that fiscal redistribution, monetary policy aimed at macro stability, and structural reforms to stimulate trade, reduce unemployment and increase productivity are important determinants of inclusive growth. The main policy implication of our analysis is that there is still room to strengthen such policies in Asia to better achieve growth with shared prosperity. In particular, scenario simulations based on our results suggests that the effect of expanding fiscal redistribution on inclusive growth could be sizeable in emerging Asia, since the estimated improvement in our proxy of inclusive growth—a measure of growth in average income “corrected” for the equity impact—ranges from about 1% to about 8% points.     

收入分配、医疗资源与人口健康:一个跨国研究

收入分配与人口健康的关系是一个争论已久的问题。本文在总结各种理论假说和以往实证研究的基础上,使用新的、质量较好的跨国面板数据,重新检验了收入分配与人口健康的关系。本文的分析重点有二:一是收入分配对人口健康的滞后影响;二是医疗资源在收入分配与人口健康的相关关系中所起的作用。本文的主要发现是,收入不均对人口健康的确有不利影响,但这种不利影响需要10年或更长的滞后期才能充分显现出来,这种滞后性是以往使用固定效应模型的跨国研究未能检测到收入不均与人口健康具有负相关关系的主要原因。此外,医疗资源(特别是初级医疗资源)人均拥有量对人口健康有积极作用;医疗资源有可能通过某种不可观察固定因素对收入分配与人口健康的关系发生影响。这些发现有助于澄清关于收入分配与人口健康关系的争论,对医疗政策也有重要参考价值。     

The growth,poverty and inequality nexus in South Africa: Cointegration and causality analysis

This study empirically established the long-run relationship and causality effects that exist between growth, poverty and inequality. The analysis was carried out on a panel of nine South African provinces from 1995 to 2012. To capture poverty and inequality in a broader context, two measures of poverty (income and non-income) and three measures of inequality (income, education and land) were adopted for the study. The results confirm that there is a long-run relationship between growth, poverty and inequality. Notable results from the causality tests suggest that growth does not promote equal distribution of income in society but as income distribution begins to equalise, economic growth rises. This is regarded as growth–inequality disconnect. The unidirectional causality, which runs from income poverty to income inequality, suggests that a rising level of income poverty will lead to falling income inequality in the society; likewise, income inequality increases as non-income poverty declines.     

Household appliance ownership and income inequality: Evidence from micro data in China

As the residential sector is becoming increasingly important in the total energy consumption and appliance ownership is a significant but under-examined driver, this study investigates the relationship between income inequality and appliance ownership using panel data from the China Health and Nutrition Survey (CHNS). We find that income inequality has negative impacts on appliance penetration rate across specifications, except for the initial development stage. On average, households start adopting air conditioners at a threshold of over 60,000 (2011 RMB) based on annual income, much higher than TV, fridge and washer (8500–9000 RMB). The empirical results validate the S-shape curve of appliance established in the literature. To understand the magnitude of the impact and policy implications, we further simulate the impact of poverty alleviation and the penetration paths under inclusive versus exclusive income growth. Our results demonstrate that current poverty line is too low to achieve appliance adoption – a signal for modern life-styles. In addition, a more inclusive growth path could lead to much higher penetration for regions that have relatively low growth rate.     

中国财政政策降低不平等的效应分析:嵌入失业风险的视角

本文通过构建一个包含个体失业风险的Hank模型来分析财政政策降低不平等的影响路径与政策效果.研究发现:(1)由于储蓄规则和流动性约束作用,不平等的加剧会增加总储蓄率,不利于向以消费为主的经济结构转型;(2)降低收入所得税对减轻不平等的效果取决于其累进程度,降低比例税可降低不平等,增加一般性转移支付对改善不平等效果不显著...     

Finance and Income Inequality: What Do the Data Tell Us?

Although there are distinct conjectures about the relationship between finance and income inequality, little empirical research compares their explanatory power. We examine the relationship between finance and income inequality for 83 countries between 1960 and 1995. Because financial development might be endogenous, we use instruments from the literature on law, finance, and growth to control for this. Our results suggest that, in the long run, inequality is less when financial development is greater, consistent with Galor and Zeira (1993) and Banerjee and Newman (1993). Although the results also suggest that inequality might increase as financial sector development increases at very low levels of financial sector development, as suggested by Greenwood and Jovanovic (1990), this result is not robust. We reject the hypothesis that financial development benefits only the rich. Our results thus suggest that in addition to improving growth, financial development also reduces inequality.     

Trade openness,FDI, and income inequality: Evidence from sub‐Saharan Africa

The motivation for this study stems from the United Nations Sustainable Development Goals (UN‐SDGs) and their impact by 2030. The UN highlights 17 SDGs that address pertinent local and global issues, one of which—SDG‐10—has been devoted to reducing inequality. This study investigates the nexus between trade openness, foreign direct investment (FDI), and income inequality in sub‐Saharan Africa using panel data from 2000 to 2015 and the generalized method of moment (GMM) technique approach. The findings show that FDI and income have a negative, statistically significant relationship with income inequality, signifying that as FDI and income per capita increase, the level of income inequality decreases. However, trade openness, education, political stability, corruption, and rule of law have a positive, statistically significant relationship with inequality. This study, therefore, offers some recommendations that will help policymakers. First, develop good policies to attract more foreign investors, which will contribute to creating employment opportunities in the region. Second, create more infrastructures to provide good quality education. Third, implement a good policy to motivate local production which will contribute to creating jobs. Fourth, build a strong institution(s) to fight against corruption.     

World economy,level development and income distribution: An integration of different approaches to the explanation of income inequality

The paper briefly outlines explanations of international differences in personal income distribution that have been formulated within the ‘world economy’ and the ‘level of development’ paradigm. The predictive power of the central variables of the paradigms are tested in a cross-national regression analysis with 72 countries. The regression results suggest support for hypotheses from both paradigms, but also suggest a partial integration of theoretical elements from both paradigms. The outcome of the proposed theoretical integration offers a new interpretation of the well-known curvilinear relationship between level of development and income inequality. This new view on the curvature of the relationship expects the integration into the world economy to result in increased income inequality in peripheral countries. But different from other views it is not implied that inequality is substantially reduced in development. The core and periphery position of countries in the world economy is seen to stabilize income inequality differences between these groups of countries. Under these circumstances, developing countries generally cannot be expected to reduce substantially their income inequality in the course of economic growth.

Fertility,income distribution,and economic growth: theory and cross-country evidence

The authors perform discriminatory, empirical tests of a theoretical model that predicts that family size adversely affects output per capita and nonsteady state growth rates. Neoclassical models posit that adverse output and nonsteady growth rates are affected by labor force growth (LFG) or population growth (PG). This study tests whether family size (FS) will be more significant than LFG or PG in explaining differences in economic growth (EG) rates across countries during 1960-88. A proxy variable for the public education system was used to separate government interventions on human capital formation from market forces. Data were obtained for 73 countries, which exclude centrally planned economies, oil-producing countries, and those with less than 1 million population. The empirical test is run with 58-country, 45-country, and 96-country samples to test for robustness and reliability. The empirical test supports the theoretical model. It demonstrates that equal distribution of income and smaller FS enhance EG. With income inequality, the effect of FS was significant, and the effect of the LFG rate or PG rate was insignificant. With a given FS, LFG was positively correlated with EG. A reduction of the net fertility rate by one point would increase the worker output growth rate by 0.25%, and the differences in growth rates between high- and low-fertility countries would be 1%. An increase in the income share of the bottom 60% would increase the growth rate of worker output by about 1%. Higher investments in public or private education would be conducive to growth.     

Political and Economic Inequities and the Shaping of Institutions and Redistribution

This article studies the joint effect of political and economic inequalities on redistributive taxation and institutional quality. The theoretical model suggests that income inequality, coupled with political bias in favor of the rich, decreases redistribution and lowers institutional quality. The effect of the former is to increase productive investment, and the effect of the latter is to decrease it—with resulting ambiguous implications for economic growth. Testing these predictions empirically in a panel of countries, we find that inequality has a negative effect on both institutional quality and redistribution.

Whatever happened to the Kuznets curve? Is it really upside down?

Kuznets (1955) embarked on a research program whose goal was to find the determinants of the long run levels and trends in income inequality and the relationship between income inequality and economic growth. Recently a small body of theoretical work has developed which tries to obtain the inverted U hypothesis as an equilibrium outcome in dynamic general equilibrium model. One of the types of general equilibrium models which can deliver a Kuznets curve is a model which allows for persistent migration out of one sector, e.g. agriculture, into another—e.g., manufacturing. Most industrialized countries have not only experienced shifts from agriculture to manufacturing, but also into services, especially associated with information technologies. This is responsible for the rise in inequality. If such a model of the arrival of new opportunities is correct, we would not expect to find a Kuznets curve, right side up or up-side down. Here we review the empirical evidence regarding the Kuzuets curve.     

对西部地区财税问题的思考

本文认为,西部地区经济欠发达有财税政策方面的原因,如地区财政支出总量不足,结构欠佳,经济发展的财政基础较为薄弱;东西部地区投资的原有财税政策差异明显,严重阻碍了资本的西流;缺乏强有力的财政政策投融资体系与政策的支持等。因此,要开发西部,关键是财税政策的调整与改进。     

实施稳健财政政策重在结构调整

我国财政政策从“积极”转到“稳健”三年来,宏观调控初见成效,但目前经济生活中存在的主要问题是收入差别明显、价格不均衡、财税政策的不完善和结构失衡。因此,2008年财政政策在总体“稳健”前提下更应注重结构调整,应加大政府转移支出的力度,优化经济结构;继续完善税制,促进经济增长;推进公共财政建设,关注民生问题。     

收入分布、厂商定价与耐用品的消费扩张

本文考察了收入差距对耐用消费品消费的影响。我们从厂商的定价理论出发。说明了收入差距对耐用消费品消费呈现出倒U型的影响：随着收入差距扩大，耐用消费品的消费量增加，但是，收入差距继续扩大则会减少耐用消费品的消费。这说明，适当的收入差距有利于社会消费水平提高和经济的发展，过大和过小的收入差距都无助于经济的起飞。我们最后运用城镇居民和农村居民彩电、洗衣机和冰箱的拥有量对该理论进行了实证检验，实证检验结果基本上支持了我们的理论分析。
