Regional income inequality in China revisited: A perspective from club convergence

Growing income inequality in China has elicited considerable concern, and consensus has not been reached regarding whether regional income converges into one common steady state. The controversy may be attributed to the various definitions and methodologies for testing convergence. This study analyzes regional income inequality and convergence in China from the perspective of club convergence proposed by Phillips and Sul (2007). Instead of one convergence at the national level, we determine that provincial incomes are converging into two clubs: seven east-coastal provinces (Shanghai, Tianjin, Jiangsu, Zhejiang, Guangdong, Shandong, and Fujian) and Inner Mongolia are converging into a high income club, and the remaining provinces are converging into a low income club. In addition, we obtain strong evidence that income inequality within a club decreases, while that between clubs deteriorates over time. Between-club inequality is associated with investment in physical and human capital, as well as population growth rates.     

Institutional inequality and tax incidence

This paper analyses the effects of taxation when inequality is not innate. A theory of institutional inequality is presented which employs a trade model with circular production and the theory of clubs. Inequality is introduced by constraints on entry into sectors and ‘local’ groups within sectors. Individual time is treated as a fixed factor of production, and work and leisure are re-defined. The analysis suggests that when inequality is institutional and government policy does not alter the mechanisms by which institutions translate the distribution of power into the distribution of income, a redistribution of income by conventional tax-transfer schemes may not always be feasible.     

Income Inequality, Competitive Balance and the Attractiveness of Team Sports: Some Evidence and a Natural Experiment from English Soccer

This paper examines the relationship between financial inequality, competitive balance and attendance at English professional league soccer. It shows that while financial inequality among the clubs has increased, competitive balance has remained relatively stable and match attendance appears unrelated to competitive balance. A clearer test of the relationship is suggested by comparison with FA Cup matches. Because income inequality is primarily driven by inter- rather than intra-divisional inequality, the FA Cup has been a much more unbalanced competition than the divisional championships. Attendance at FA Cup matches relative to the corresponding league matches has fallen over the last twenty years.     

Income convergence clubs for Brazilian Municipalities: a non-parametric analysis

This article analyses the evolution of relative per capita income distribution of Brazilian municipalities over the period 1970–1996. Analyses are based on non-parametric methodologies and do not assume probability distributions or functional forms for the data. Two convergence tests have been carried out – a test for sigma convergence based on the bootstrap principle and a beta convergence test using smoothing splines for the growth regressions. The results obtained demonstrate the need to model the dynamics of income for Brazilian municipalities as a process of convergence clubs, using the methodology of transition matrices and stochastic kernels. The results show the formation of two convergence clubs, a low income club formed by the municipalities of the North and Northeast regions, and another high income club formed by the municipalities of the Center-West, Southeast and South regions. The formation of convergence clubs is confirmed by a bootstrap test for multimodality.     

GLOBALIZATION AND REGIONAL INCOME INEQUALITY: EMPIRICAL EVIDENCE FROM WITHIN CHINA

China's recent accession to the WTO is expected to accelerate its integration into the world economy, which aggravates concerns over the impact of globalization on the already rising inter-region income inequality in China. This paper discusses China's globalization process and estimates an income generating function, incorporating trade and FDI variables. It then applies the newly developed Shapley value decomposition technique to quantify the contributions of globalization, along with other variables, to regional inequality. It is found that: (a) globalization constitutes a positive and substantial share of regional inequality and the share rises over time; (b) domestic capital, however, emerges as the largest contributor to regional inequality; (c) economic reform characterized by privatization exerts an increasingly significant impact on regional inequality; and (d) the relative contributions of education, location, urbanization and dependency ratio to regional inequality have been declining.     

Urban–rural gap and poverty traps in China: A prefecture level analysis

Urban–rural gap and regional inequality are long-standing problems in China and result in considerable number of studies. This article examines the dynamic behaviours of incomes for both urban and rural areas with a prefectural data set. The analysis is conducted by using a distribution dynamics approach, which have advantages in examination on persistence, polarization and convergence clubs. The results show that persistence and immobility are the dominant characteristics in the income distribution dynamics. The prefectural urban and rural areas converge into their own steady states differentiated in income levels. This pattern of urban–rural gap also exists in three regional groups, namely the eastern, central and western regions. Examination on the dynamics of the poorest areas shows that geographical poverty traps exist in both urban and rural prefectural areas. Our results indicate that more policy interventions are required to narrow down the urban–rural gap and to eliminate the poverty traps in China.

Educational systems,growth and income distribution: a quantitative study

This study sets out to develop a dynamic model within an economy characterized by the coexistence of public and private schools, under imperfect credit market conditions, in an attempt to provide a clearer understanding of the evolution of economic growth and income inequality. We find that any government wishing to reduce income inequality should adopt policies aimed at increasing the enrollment rate in public schools. However, whilst high enrollment rates can be sustained in private schools, and thus create enhanced economic growth, this can only occur if accompanied by the liberalization of the credit markets.     

THE DISTRIBUTION OF INCOME IN TRINIDAD AND TOBAGO, 1957–76*

This article describes what happens to income distribution during intensive changes in gross domestic product due to external market conditions. It deals specifically with an open market petroleum-based economy, Trinidad and Tobago, and reviews changes in national product and income levels and the income distribution pattern over the twenty year period 1957–76. The paper argues that during the period characterized by subperiods of steady growth and rapid growth in GDP (the latter associated with the petroleum price rise), income inequality increased between 1957 and 1972 and then decreased in the post petroleum-price-rise period of rapid growth 1973–76. While the effect of intensive changes in national product did trickle down to the lower income groups, income inequality in 1975–76 was greater than that existing in 1957–58. An examination of the spatial, occupational and temporal aspect of the distribution pattern points towards the elimination of structural dualism in the economy as the surest path towards greater income equality in Trinidad and Tobago.     

Non-Linearity and Cross-Country Dependence of Income Inequality

We use top income data and the newly developed regime-switching Gaussian mixture vector autoregressive model to explain the dynamics of income inequality in developed economies within the past 100 years. Our results indicate that the process of income inequality consists of two equilibria identifiable by high inequality and high income fluctuations, and low inequality and low income fluctuations. Our results also imply that income inequality in the United States is the driver of income inequality in other developed economies. High wages and capital gains are found to be the likely channels for the U.S. influence.     

Measures of distance between income distributions

This paper presents a class of measures of distance between two income distributions. The measures are based on distribution functions and evaluate the degree of inequality of income between two populations. This class of measures is derived by an axiomatic approach and it is completely characterized by the properties normally associated with a distance function and a set of axioms.

Persistence and determinants of income inequality: The Brazilian case

Latin America, which is a region known for its high and persistent income inequality levels, experienced a significant decline in income inequality since the second half of the 1990s. Brazil is a particularly interesting case in Latin America. While the country presented notable economic growth and improvements in income distribution in the early 2000s, Brazil continues to experience high levels of income inequality in comparison with other Latin American or advanced economies. This research contributes to the literature by examining the key drivers of income distribution and the degree of persistence of income inequality among Brazilian states. This research also improves upon previous works by using more recent and comprehensive data and addressing concerns regarding heterogeneity and endogeneity by using the system GMM estimation method. Our findings show that income inequality is highly persistent across Brazilian states and that government policies including income transfer programs made important contributions to reduce income inequality in Brazil. This study also shows that the decline in labor income ratios between different ethnic groups and the increase of the share of formal jobs in the labor market contributed to reduce income inequality.     

The impact of education expansion on wage inequality

The findings on education expansion and income inequality have important implications for policymakers to implement effective policies to reduce income inequality. This study attempts to explain how education expansion affects income inequality by education distribution and the rate of return to education. We decompose the effect of education expansion on wage gaps into price effect and structure effect. We compare the income inequality from 2002 to 2013 using the Chinese Household Income Project (CHIP) 2002 and CHIP2013 survey data and employ FFL decomposition method. Our findings suggest that income inequality increased in 2013 and that income inequality among the high-income groups increased even more significantly. The structure effect of education expansion on income inequality is negative, when average education increases one year, the income gap between 80th and 20th will decrease 1.2%, in other words, education expansion decreases income inequality by allowing a wide range of individuals to attend college. However, this effect is offset by the price effect, which is positive and much more significant in magnitude. One extra year of average education will increase income gap by 29% which means that the demand for high-skilled labour is increasing faster than the supply and thus lead to the increasing premium for higher education return.     

Poverty decompositions with counterfactual income and inequality dynamics

Traditional poverty accounting decomposes changes in a country's poverty headcount ratio into changes in income and inequality. We argue that this approach is unsatisfactory from the perspective of policy analysis because it compares a country in two points of time without taking the country's initial situation, and hence its potential for poverty reduction, into account. We thus suggest comparing traditional poverty decompositions with a counterfactual situation. This counterfactual indicates what a country starting from its initial situation could be expected to achieve in terms of income, inequality, and, hence, poverty developments. We construct those counterfactuals by modeling income and inequality trends characterized by convergence and a “Kuznets” relationship between inequality and development. Parameters in those relationships are estimated using PovcalNet survey data from 144 countries and we construct our counterfactual poverty predictions for 71 developing countries. While there is overall a tight relationship between actual developments and counterfactuals, we identify several cases, where both deviate from each other and discuss the policy implications. We also check for commonalities in differently performing countries and find that those who fell particularly short of expectations often underwent political transition and state fragility.     

Income inequality and income bias in voter turnout

In the era of growing income inequality around the world, it remains inconclusive how higher income inequality affects income bias in turnout (i.e., high-income citizens vote more likely than low-income citizens). Using large-scale cross-national survey data, we show that (1) strong income bias in turnout exists in many parts of the world, (2) higher income inequality is related to lower income bias in turnout by demobilizing high-income citizens and mobilizing low-income citizens, and (3) this relationship is partly explained by the pattern that vote buying is more common in societies with higher income inequality and thus mobilizes low-income citizens but decreases political efficacy among high-income citizens. Ultimately, this study suggests that growing income inequality may not exaggerate political inequality, but may challenge the legitimacy of democratic elections.     

中国农村居民收入区域不平衡的动态变化及影响因素——基于人口加权变异系数的分析

论文使用人口加权变异系数探析1993—2009年中国农村居民收入区域不平衡的动态变化,并通过对人口加权变异系数进行空间和收入来源的二重分解,分析这种变化的空间和收入来源影响因素。研究发现,中国农村居民收入区域不平衡程度总体上趋于下降,但自1998年以来下降幅度很小。东部、中部、西部和东北四大区域之间的农村居民收入不平衡是影响中国农村居民收入区域不平衡的主要因素,其次是这四大区域内部的不平衡。从收入来源看,工资性收入是导致中国农村居民收入区域不平衡的最主要因素,其次是家庭经营性收入。     

Regional divergence and club convergence in India

This paper examines regional divergence in income across different states in India, and estimates convergence clubs endogenously. The paper makes two useful contributions. First, the data is analyzed using a novel method due to Phillips and Sul (2007) leading to different conclusions in comparison to past studies, and secondly sectoral level data is employed which to our knowledge has not been employed in the literature before. Applying the novel approach to panel data relating to fifteen major states of India for the period 1968/69–2008/09, the results display significant divergence in per capita income across states at the aggregate and sectoral levels. There is also evidence of convergence clubs and variations in the number and composition of clubs across sectors. While three clubs are identified at the aggregate level, at the sectoral level we find three clubs in the industrial sector, two clubs are identified in both the agriculture and services sectors. The final part of the paper deals with the policy implications.     

CHANGES IN CANADIAN FAMILY INCOME AND FAMILY CONSUMPTION INEQUALITY BETWEEN 1978 AND 1992

This paper uses Canadian cross-sectional income and expenditure data to examine changes in the distribution of family income and family consumption during the period 1978 to 1992. Family consumption data are analyzed because in the presence of intertemporal consumption smoothing, the cross-sectional distribution of consumption may characterize the distribution of lifetime wealth. I find that both Canadian family income inequality and Canadian family consumption inequality moved countercyclically. In addition, both Canadian family income inequality and Canadian family consumption inequality trended upward over the period; however, the change in family consumption inequality was much smaller than the change in family income inequality, suggesting that inequality in the distribution of lifetime wealth may have changed much less than is suggested by changes in the distribution of income.
