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.     

经济集聚与经济增长——基于中国城市数据的实证分析

新经济地理学已经成为主流经济学中的一个新的亮点，有大量文献从理论和实证两方面针对经济积聚的原因及其对经济增长的影响展开了分析，然而基于中国数据的实证分析并不多。本文基于中国城市的面板数据实证检验了经济集聚对于城市人均实际GDP的影响，结果发现，如果不考虑经济集聚的内生性问题，会得到向下偏误的结果。本文运用工具变量法的回归结果表明：经济集聚具有内生性，它对于城市经济增长具有显著的促进作用。     

Rank, income and income inequality in urban China

While some workers in China attain senior professional level and senior cadre level status (Chuzhang and above), others attain middle rank including middle rank of professional and cadre (Kezhang). This aspect of the Chinese labour force has attracted surprisingly little attention in the literature, a fact which this paper aims to rectify. We define various segments of the urban population in work-active ages and use data from the Chinese Income Project (CHIP) covering eastern, central and western China for 1995 and 2002. For 2002, persons of high rank make up 3% and persons of middle rank make up 14% of persons in work-active ages.Factors that affect a person's likelihood of having high or middle rank are investigated by estimating a multinomial probit model. We find that education, age and gender strongly affect the probability of being employed as a worker of high rank. There is relatively little income inequality among workers of high rank as well as among workers of middle rank. Mean income and household wealth per capita of highly-ranked workers developed more favorably than for other segments of the population studied, and personal income is more polarized by segment in 2002 than in 1995. Workers of high rank, and to a lesser degree, workers of middle rank, are among the winners in economic terms while the increasingly large category of non-workers is the losers. Rates of return to education have increased but income function analysis indicates that this provides only a partial explanation for the increased favorable income situation for workers of high and middle ranks.

The impact of agricultural technology adoption on income inequality in rural China: Evidence from southern Yunnan Province

This study analyzes the impact on income inequality of government efforts to increase agricultural incomes in rural China. It collects and analyzes survey data from 473 households in Yunnan, China in 2004. In particular, it investigates the effects of government efforts to promote improved upland rice technologies. Our analysis shows that farmers who adopted these technologies had incomes approximately 15% higher than non-adopters. Despite this relatively large increase, we estimate that the impact on income inequality was relatively slight. This is primarily due to the fact that lower-income farmers adopted the improved rice technology at rates that were roughly equivalent to those of higher-income farmers.     

Carbon inequality in China: Evidence from city-level data

Carbon inequality has attracted increasing attention worldwide. Utilizing data from China's High Spatial Resolution Emission Gridded Database (CHRED), this paper presents the measured CO₂ emission inequality in China for the years 2005, 2012, 2015, and 2020. Results show that the Gini coefficients of carbon emission report a slight decrease from 0.411 to 0.385 and the distribution becomes more symmetric from 2005 to 2020. Linking carbon inequality to economic level, the positive concentration index (0.230 to 0.118) indicates asymmetricity between carbon emission and economic development. A further decomposition analysis reveals the industrial sector's uneven development, indicating that energy-intensive features can be blamed for a large proportion of carbon inequality. Our findings suggest that policymakers should not consider economic development level alone as the only indicator of the allocation of abatement, as economic structure, energy intensity, and climate conditions are all responsible for such inequality.     

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.     

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.     

Macroprudential policy and household wealth inequality: Evidence from China

The influence of LTV ceiling on household wealth inequality is not constant. This paper finds that when the return on housing investment is higher than the return on liquid assets, the LTV ceiling generally has a negative impact on household wealth inequality; otherwise, it is more likely to be positive. Increasing the LTV ceiling can significantly alleviate household wealth inequality in China. Housing price and the number of houses purchased are important channels, and the house purchase preference (savings rate and house purchase intention) plays a key role in regulating wealth distribution through the LTV ceiling.     

Tariffs,relative prices and wage inequality: Evidence from China

This paper, based on data from China after its membership into the World Trade Organization (WTO), shows the co-existence of a fluctuating skill premium and rises in wages for both skilled and unskilled labor. Our research provides one specific factor, the tariff reduction biased toward unskilled labor-intensive sectors, to explain and quantify the magnitudes of skill premium dynamics using the mandated-wage approach. The empirical evidence indicates that sector-biased tariff reductions have widened wage inequality in China through their effect on product prices. World price competition, on the other hand, has contributed to declining wage inequality via product prices, which is consistent with the endowment-based expectations of China's integration into the more skilled-labor abundant world.     

Intergenerational income persistence and transmission mechanism: Evidence from urban China

In this paper I investigate the intergenerational income association and its transmission channels amid China's economic transition period using urban data from the Chinese Household Income Projects in 1995 and 2002. The estimated intergenerational income elasticity is 0.43 and 0.51 for cohorts educated prior to and after the market reform respectively, and reaches 0.71 among households with above average income in the post-reform era. Besides the conventional channel of education, this paper estimates the contribution from social capital and ownership of work unit across cohorts and income groups. There is weak evidence that prior to market reform, ownership of work unit contributes most to the intergenerational income persistence for households with below average income, while social capital leads the three contributors in households with above average income. However, in the post-reform era, parents with below average income invest statistically significantly in children's education which contributes most to the intergenerational income persistence. The leading contributor in families with above average income shifts to social capital. Possible explanations for such a shift lie in the ability and incentive of parents from different income categories to invest in their children. The results are tested through a series of robustness checks, and provide empirical support for promoting policies on the equality of opportunity.     

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.     

The urbanization-household gender inequality nexus: Evidence from time allocation in China

Urbanization and accompanying socio-economic change, alter intra-household behaviours including paid and unpaid work patterns. China's rapid urbanization raises important questions about the changing nature of gender asymmetries in the household division of labour. Using 24-hour time module data from the China Family Panel Studies, we investigate time allocation of females and males in matched-couples in urban, rural-urban migrant, and rural households. Our model explicitly incorporates the impact of care of young children on time-use. Distinguishing between care and other housework, overall, we find while traditional gendered time-use patterns persist among rural households, urbanization and migration reduces gender differentials in unpaid work. Both urban and migrant fathers engage in more care work than their rural counterparts. We shed new light on the configurations of paid and unpaid work, leisure and self-care; women's burden of a ‘second shift’ of unpaid work; the role of education and income in eroding gender norms; and the impact of grandparents on time-use.     

电力消费和经济增长：来自中国的证据

对1971—2009年中国人均实际GDP和人均耗电量的Zivot-Andrews单位根检验表明,两序列都是带有结构突变的趋势平稳过程,所以,采用两种方法检验两者间的因果关系:基于VAR的Dolado-Lütkepo检验,和基于去势数据的Granger因果检验。两种检验都取得了从人均耗电量到人均实际GDP的单向因果关系的有力证据。这意味着电力供应对满足日益增长的用电量,从而维持中国经济增长是至关重要的。     

Migration,population aging,and income inequality in China

In this study, we examine the effects of four demographic factors, namely, birth, death, natural aging, and net migration, on population aging and income inequality in China. We use the official Chinese data and the China Household Income Project Survey data for the 2007–2013 period and apply a decomposition model based on the Shapley method. Unlike previous studies, we include migration in our decomposition model and find that natural aging is the primary factor contributing to population aging in both urban and rural areas. Further, migration may accelerate population aging in rural areas. Moreover, migration contributes to reducing income inequality in urban areas, while widening income inequality in rural areas. The effect of migration is larger than those of birth, death, and natural aging on income inequality. The robustness checks confirm these conclusions.     

Top incomes in China: Data collection and the impact on income inequality

Using data on top incomes collected from different sources, we combine the samples of top incomes with a household survey (HS) to investigate changes in income distribution with and without top incomes. The Gini coefficient of income inequality using HS data is 0.464 for 2016 and jumps to 0.646 after including the samples of top incomes, which demonstrates the importance of top incomes in estimating income inequality.     

Trade openness and income inequality in China and the SAARC Region

The paper empirically examines the effects of trade liberalisation on income inequality in China and the South Asian Association for Regional Cooperation countries. Panel data analysis is conducted for the period of 1973 to 2012. The results show that liberal trade policies have increased income inequality in these countries. These results are robust to alternative liberalisation measures. The control variables used have differing effects on income distribution. Per capita income has an increasing effect on income inequality, while education, financial development, financial openness, democracy, and government size are shown to reduce income inequality. These outcomes can be expected to have important policy implications for the use of trade liberalisation in these countries.     

Inward and outward FDI and income inequality: evidence from Europe

This paper examines the effects of inward and outward FDI on income inequality in Europe using panel cointegration techniques and unbalanced panel regressions. Our main result is that both inward FDI and outward FDI have, on average, a negative long-run effect on income inequality. This result is robust to employing alternative estimation methods, controlling for potential outliers, using different measures of FDI and inequality, and changing the period and sample selection. Other findings are: (i) while the long-run effect of inward and outward FDI on income inequality is clearly negative, their short-run effect appears to be positive. (ii) Long-run causality runs in both directions, suggesting that an increase in inward and outward FDI reduces income inequality in the long run, and that, in turn, a reduction in inequality leads to an increase in inward and outward FDI. (iii) There are large cross-country differences in the long-run effects of inward and outward FDI on income inequality; for some countries the long-run effects on income inequality are positive.     

Patrilineality,fertility, and women's income: Evidence from family lineage in China

This study investigates how traditional patrilineal family institution influences women's income through fertility behavior by offering evidence from family lineage (zongzu) in China. We hypothesize that family with strong lineage—proxied by owning genealogy—has a negative effect on women's income through the son-targeting fertility behavior. Using a difference-in-differences strategy, this study confirms the hypothesis. Relative to the women whose first child is a son, the women marring into families owning genealogy indeed have more children and lower income, if their first child is a daughter. In contrast, such finding does not hold for the male sample. Preliminary evidence suggests that shorter work time can explain the findings.     

Global value chains,firms, and wage inequality: Evidence from China

How does participating or moving to more upstream in the global value chains (GVCs) affect the premium paid to skilled compared to unskilled labor within firms? In this paper, we develop a model of heterogeneous firms with intermediate trade and two skill inputs, in which we apply the fair wage hypothesis to predict the wage premium changes according to firms' GVCs activities. The model predicts that firms' backward GVC participation, as measured by the share of foreign value-added content in exports (FVAR), has an ambiguous impact on wage inequality of skills, which depends on the relative importance of “FVAR-labor substitution effect” and “FVAR-profit effect.” However, moving to upstream sectors in GVCs, as measured by the export varieties' upstreamness (or average distance from final use), raises a firm's wage premium. Using detailed Chinese firm-level data from 2000 to 2006, we develop a Mincer-type empirical model to study the wage premium changes associated with FVAR and upstreamness. We find robust empirical evidence that the rise of wage inequality in China mainly arises from moving to more upstream sectors rather than changing GVC participation.
