Ownership and earnings inequality in urban China

Along with advances in urban state-owned enterprise reform, fast growth of private sector and changes in the wage structure, earnings inequality in urban China has been increasing. Using data from the 1988 and 2007 waves of the urban household survey conducted by China Household Income Project, this paper attempts to examine the impact of the change in ownership structure on earnings distribution in urban China. We find that developing non-state-owned enterprises (nonSOEs) or privatization of state-owned enterprises (SOEs) enlarge earnings inequality, but the difference in earnings level between the two sectors is small. Although workers in SOEs receive higher income than in nonSOEs, the difference is more caused by endowment difference rather than coefficient differences. Introducing market power to wage determination system is more influential to the rising earnings inequality which leads more rewards on working experience and educational attainment.     

The impact of growth and inequality on rural poverty in China

This paper analyzes the evolution of poverty in China from the late 1980s to the late 1990s, employing a version of Shapley decomposition tailored to unit-record household survey data. The changes in poverty trends are attributed to two proximate causes—income growth and shifts in income distribution. Different data sets, poverty lines, poverty measures, and equivalence scales are used to examine the robustness of the results. Potential biases arising from ignoring differential regional prices and inflation are also investigated. Notwithstanding some ambiguities in the results, it is consistently found that rural poverty increased in the second half of the 1990s and adverse distributional changes are the main cause.

The impact of unemployment on inequality and poverty in OECD countries

The purpose of this research is to examine the contribution of unemployment to income inequality and poverty in various OECD countries. These relationships have been explored using Luxembourg Income Study micro-data. Considerable differences across OECD countries are revealed through the use of within-household unemployment distributions. These differences help to explain most of the observed divergences in the relationship between unemployment and income distribution, in conjunction with the heterogeneous influence of social benefits on the economic position of the unemployed in these countries. A sub-group decomposition analysis corroborates the limited effect of unemployment on income distribution in most of the considered countries. However, it seems clear that the unemployed are among those with the highest risk of experiencing poverty.

Increasing urban wage inequality in China

Two strictly comparable cross‐section household datasets, relating to 1988 and 1995, are used to analyse the increase in wage inequality from an initially low level in urban China over this period of labour market reform. The institutional background and the evolution of policy are described. The rapid growth of wage inequality and the sharp widening of wage structure are quantified. Earnings functions are compared, and the increase in both the level and the inequality of wages are decomposed into their constituent elements. Quantile regression analysis is conducted to throw light on the relationships between the observed and the unobserved determinants of wages. Distinctions are made between the variables likely to represent human capital, discrimination, and segmentation. The evidence suggests that productive characteristics were increasingly rewarded as marketization occurred, but that discrimination and segmentation also grew. The move towards a fully‐fledged labour market was by no means complete.     

Migration and rural poverty in China

We analyze two complementary household datasets from China's poor areas to examine whether the poor migrate and whether migration helps the poor. We find an inverted-U-shaped relationship between household endowments and the likelihood of migration. Over time, the poor are more likely to migrate. Using household panel data and taking prior village migration networks as an instrument, we find that having a migrant increases a household's income per capita by 8.5 to 13.1 percent, but that the overall impact on poverty is modest because most poor people do not migrate. Migrants remit a large share of their income and the amount of these remittances is responsive somewhat to the needs of other family members.

Stochastic dominance and decomposable measures of inequality and poverty

In this paper, we characterize some new links between stochastic dominance and the measurement of inequality and poverty. We show that: for second-degree normalized stochastic dominance (NSD), the weighted area between the NSD curve of a distribution and that of the equalized distribution is a decomposable inequality measure; for first-degree and second-degree censored stochastic dominance (CSD), the weighted area between the CSD curve of a distribution and that of the zero-poverty distribution is a decomposable poverty measure. These characterizations provide graphical representations for decomposable inequality and poverty measures in the same manner as Lorenz curve does for the Gini index. The extensions of the links to higher degrees of stochastic dominance are also investigated.     

Trade liberalisation,poverty, and inequality in Vietnam: a quantile regression approach

This study examines the effects of trade liberalisation on rural household welfare, poverty, and inequality in Vietnam, with the use of multiple estimation strategies, including the panel quantile regression approach based on Canay's two-step estimator. Taking account of the multi-faceted nature of trade liberalisation, we consider a set of household-level trade-related variables, including employment in export, import-competing, and manufacturing sectors. A unique panel data set is constructed from the Vietnam Household Living Standards Surveys conducted in 2002, 2004 and 2006. We find that employment in trade-related sectors contributes significantly to rural household welfare. Moreover, the effects of trade-related employment on welfare are heterogeneous across the welfare/income distribution, in that trade-related employment sectors have different influences on different groups/quantiles of households.     

Simulation of the impact of economic policies on poverty and inequality: GEM in micro-simulation for the Algerian economy

This paper presents an illustration of the importance of computable general equilibrium modelling micro-simulation for simulating the impact of economic policies on living levels of households. The CGEM, as built, was used to simulate the effects of some economic policies on the economy and living levels of all households including the classes of modest, middle and wealthy households. In this context, pro-active economic policies are simulated in order to understand their effects on the macroeconomic plan and on the living level of some household categories defined according to statistical criteria. The first on the analysis of two arbitrarily selected tax policy cases, and the other on three investment policy simulations. Different illustrated simulations show improvements in economic growth and upward social mobility, particularly in the case of increasing the overall investment and improving productive capacity. In all simulations, that inequality would have remained rigid downward and would sometimes even accentuate. Overall, it appears that the increase in investment would boost economic growth through demand effect. However, this increase in demand would be met by more imports, which would damage our trade balance. The national productive system, however, could reverse this trend by making profitable investments by strengthening its productive capacity.     

National pro-poor spending programmes and their effect on income inequality and poverty: Evidence from Vietnam

This article examines the causal effects of the national (pro-poor) targeted programmes (NTPs) on both poverty incidence and inequality in Vietnam over the period 2002–2010. While the links between NTPs and poverty alleviation and income inequality have previously been analysed independently, this study is the first to offer a comprehensive analysis of NTPs expenditure on poverty and inequality simultaneously. Applying the system generalized method of moments estimator to a panel of Vietnamese regional data, we are unable to establish that NTPs have significantly mitigated poverty incidence. However, we estimate that NTPs have significantly increased inequality. We offer possible explanations why the NTPs have resulted in these unintended outcomes and discuss potential policies which can reduce both poverty and inequality.     

Wage inequality and between-firm wage dispersion in the 1990s: A comparison of rural and urban enterprises in China

Using a worker–firm matched sample, this paper compares the changes of wage structures of urban and rural enterprises following public sector restructuring in China's manufacturing sector. While the wage responses of rural firms with respect to firm characteristics are found to have declined steadily, compensation of urban workers has become increasingly linked to their firms' ability to pay. Our analysis reveals that industrial restructuring has weakened the influence of institutional factors, such as market power, soft budget constraints, and insider influence, on the wage determination of rural firms but it has enhanced their impact on urban firms.

Social mobility and inequality in urban China: understanding the role of intergenerational transmission of education

China’s rapid economic growth since the late 1980s has been accompanied by great economic and social transformations, which have resulted in a sharp increase in income inequality. This article contributes to the literature of social mobility in China by examining the impact of parental education on the education of their children. Using the 1990 and 2000 Chinese Population Censuses, we employ nonparametric estimation strategies to provide a systematic investigation of intergenerational transmission of education in urban China. We find evidence of increasing parents–children educational correlations. Our results raise concerns regarding economic inequality in urban China as high intergenerational persistence of education is expected to be a barrier to equal opportunities in children’s education attainments and their future labour market outcomes.     

The impact of natural disasters on household income,expenditure, poverty and inequality: evidence from Vietnam

Natural disasters are expected exacerbate poverty and inequality, but little evidence exists to support the impact at household level. This article examines the effect of natural disasters on household income, expenditure, poverty and inequality using the Vietnam Household Living Standard Survey in 2008. The effects of a natural disaster on household income and expenditure, corrected for fixed effects and potential endogeneity bias, are estimated at 6.9% and 7.1% declines in Vietnamese household per capita income and expenditure, respectively. Natural disasters demonstrably worsen expenditure poverty and inequality in Vietnam, and thus should be considered as a factor in designing poverty alleviation policies.     

Evolution of wealth inequality in China

Household wealth is a key indicator that reflects national economic competiveness and individual income levels. The distribution of wealth is central for evaluating social justice in a country. This article uses a data set composed of the 2002 China Household Income Project and the 2010 Chinese Family Panel Survey to analyze the level of wealth and wealth inequality in China during 2002 and 2010. The analysis decomposes the evolution of wealth inequality during that period in terms of the structure and composition of wealth. The findings show that there was a large increase in the quantity of wealth and wealth inequality between 2002 and 2010. The level of wealth in 2010 was four times that of 2002, and housing assets were the greatest component of overall wealth in 2010. Wealth inequality also rose dramatically after 2002, with the Gini coefficient of the distribution of wealth increasing from 0.538 in 2002 to 0.739 in 2010. The rapidly escalating price of housing has been the main contributor to increasing wealth inequality in recent years.     

Unfair inequality and growth*

Fighting against economic inequality is one fundamental social goal in the agendas of most governments. However, recent studies highlight that people actually prefer unequal societies, as they accept inequality generated by an individual's effort and wish to reduce only unfair inequality (generated by factors beyond an individual's control). This distinction might help to explain the fundamental unsolved question about whether inequality is good or bad for growth: unfair inequality (UI) could be growth-deterring, while fair inequality (FI) might be growth-enhancing. We derive a reduced-form growth equation from a stylized overlapping-generations model with human capital that includes FI, UI, and poverty. Then, using an instrumental variable approach, we show for alternative samples and inequality measures at the worldwide level that the estimated coefficient associated with UI is always negative, while the coefficient of total inequality increases when UI is included in the regression. Moreover, we find that poverty mediates this relationship because the higher the poverty rate, the smaller the impact of either type of inequality on growth.     

Income inequality in China: causes and policy responses

The phenomenal economic growth in China has been accompanied by a rapid increase in income inequality. This paper reviews the historical trends and patterns of income inequality in China, discusses the potential causes underlying rising income inequality, and applies the functional distribution of income approach in understanding China’s income inequality. This analytical approach highlights how rising return to capital relative to wage incomes can be an important source for increasing income inequality in China. The paper provides the evidence which shows that the rapid economic growth in China has been relying on a model that pays high returns to various kinds of capital including financial capital and real estate, while the ownership of capital is very unequal. This finding prompts us to rethink about the causes of China’s income inequality and to formulate appropriate policies based on the new way of understanding this pressing issue of income distribution in China.     

The impact of work and non‐work migration on household welfare,poverty and inequality

This article estimates the impact of work migration and non‐work migration on per capita income, per capita expenditures, poverty and inequality in Vietnam using data from the two most recent Vietnam Household and Living Standard Surveys. We find that both work migration and non‐work migration have a positive impact on per capita expenditures of migrant‐sending households. Non‐work migration significantly decreases the incidence, depth and severity of national poverty. The effect of work migration on poverty is much smaller. Still, while work migration does not lift people out of poverty, it makes their poverty less severe. In addition, both work migration and non‐work migration decrease inequality, albeit only very slightly.     

Poverty,inequality and ethnic minorities in Vietnam

The present study examines how and why ethnic minorities are poorer than ethnic majorities in Vietnam using the Vietnam Household Living Standards Survey data for 2002 and 2004. First, the analysis confirms that households belonging to the ethnic minority groups are not only poorer but also more vulnerable to various shocks than those in the ethnic majority groups, namely the Kinh and the Chinese. Second, household composition (e.g., dependency burden), education, land holding and location are important determinants of expenditure and poverty, whilst there is some diversity among different ethnic groups. Finally, the decomposition analyses reveal that the ethnic minorities are poorer not necessarily because they have more disadvantaged household characteristics (e.g., educational attainment or location), but, more importantly, because the returns to the characteristics are much lower for ethnic minorities than for the majorities. Government policies to reduce structural differences between ethnic majorities and minorities are imperative to address the disparities in returns to endowments between them.     

Reform,Growth, and Inequality in China*

This paper provides a survey of the literature on inequality in China – level, change, causes, and consequences. It attempts to answer six main questions. How much has inequality risen? What is its relation to poverty alleviation? What has happened to wealth inequality? What are the main dimensions of rising income inequality? The dimensions examined are: the rural–urban divide; urban labor market reform; regional divergence; rural–urban migration; and entrepreneurship, rent‐seeking, and corruption. Was it inevitable that inequality should rise so much? Does it matter that inequality has risen? Income distribution in China is bound up with both economic reform and economic growth. This paper concludes by considering the countervailing forces that will determine the path of inequality in future years.     

Urban bias and wage inequality

This paper explores how urban bias affects skilled–unskilled wage inequality through building several general equilibrium models. In the basic model, we find that an increase in the degree of urban bias will widen wage inequality if the unskilled sector is more capital intensive than the skilled sector and reduce wage inequality if the skilled sector is more capital intensive than the unskilled sector. In the extended models, we find that the conclusion obtained in the basic model almost still holds under different conditions.     

中国农村人口省际省内迁移机制研究

本文基于农村劳动力转移理论和人口迁移理论,较为全面、综合地从8个层次选择了一系列变量,采用多元回归分析法对各个层面的影响因素进行的精确分析。研究发现,农村剩余劳动力省内转移与省际转移的驱动机制不同。相对较高的迁移成本使得跨省迁移的决策更需要劳动力理性的判断和思考.转移决策更多地取决于就业机会。
