Intergenerational mobility of earnings in South Korea

The purpose of this study is to estimate the extent of intergenerational mobility of earnings in the Republic of Korea (South Korea). The elasticity of children's earnings with respect to parent's earnings is estimated using household microdata. When the simulation extrapolation (SIMEX) method is applied along with the multiyear-average method, the elasticity is estimated to be 0.24 or less for sons approximately 30 years old. When the two-stage approach is applied, the elasticity is approximately 0.25 for sons and 0.35 for daughters in their 30s, and approximately 0.35 for sons and 0.4 for daughters from 25 to 54 years old. Nonparametric regression illustrates that sons from low-income families in the younger generation have more equal opportunities than in the older generation     

Social protection,redistribution and economic growth

Social protection has conventionally been associated with redistribution and equity. This paper examines the effects of different types of social protection on economic growth. It looks at the possible effects on human capital formation, on physical investment and innovation, on the local economy and on the macroeconomy, discusses these effects in theory and reviews empirical evidence of such effects. It considers the widely varying impacts that different types of social protection can have on the distribution of incomes and on economic growth. The paper concludes that, in analysing, assessing and planning social protection, it is crucially important to consider the potential drawbacks – and the benefits.     

Describing and decomposing post-apartheid income inequality in South Africa

This paper describes the changes in inequality in South Africa over the post-apartheid period, using income data from 1993 and 2008. Having shown that the data are comparable over time, it then profiles aggregate changes in income inequality, showing that inequality has increased over the post-apartheid period because an increased share of income has gone to the top decile. Social grants have become much more important as sources of income in the lower deciles. However, income source decomposition shows that the labour market has been and remains the main driver of aggregate inequality. Inequality within each racial group has increased and both standard and new methodologies show that the contribution of between-race inequality has decreased. Both aggregate and within-group inequality are responding to rising unemployment and rising earnings inequality. Those who have neither access to social grants nor the education levels necessary to integrate successfully into a harsh labour market are especially vulnerable.     

创新与收入不平等

文章运用1995-2014年中国省际面板数据,从部门内和部门间两个视角,考察总体创新和产业创新水平对收入不平等的影响。实证结果表明不同类型的创新活动对收入不平等产生了不同影响：对于城镇居民收入不平等,总体创新水平和高新技术创新水平具有显著的扩大作用,创新带来了不同收入阶层内部的分化;对于农村居民收入不平等,农业创新水平具有显著的缩小作用,显示出农业创新对农民增收的积极作用;对于城乡收入差距,总体创新水平和农业创新水平具有缩小作用,而高新技术产业创新水平具有显著扩大作用。不仅如此,由于城乡收入差距存在显著的正向空间自相关,总体创新和高新技术产业创新对相邻地区城乡收入差距有显著的扩大作用。     

The convergence dynamics of economic freedom across U.S. states

This study tests for convergence in economic freedom across the 50 U.S. states from 1981 to 2019. In particular, we test for stochastic convergence in overall economic freedom using unit root tests that account for structural breaks and bounded processes, two sources of parameter instability. We find limited evidence of stochastic convergence. Further analysis of relative (club) convergence and weak σ-convergence rejects the presence of overall convergence in the panel of the U.S. states, but the emergence of two convergence clubs with respect to state-level economic freedom. The logit analysis of the determinants of the convergence clubs reveals that more prosperous states and states with a higher initial level of economic freedom have a higher probability of being in the club with more economic freedom. However, more racially diverse states have a lower probability of being in the club with more economic freedom.     

父代关系与代际收入流动：基于教育和就业的视角

文章运用计量方法分析了父代关系与中国代际收入流动性的关系。我们用2010年中国家庭追踪调查中父代为了子女上学和就业“找关系”来衡量寻租行为,通过工具变量法和分位回归法探讨了父代关系对不同人群的影响。结果显示,为子女就学（就业）找关系对于代际收入流动有一定的促进作用;进一步,分位回归和不同社会区域特征的影响揭示,教育和就业领域的“寻租市场”远远不是完全有效市场,在这一市场中所进行的寻租行为进一步加剧了教育和就业资源在城乡之间、不同收入阶层之间原本就存在的分布不均。教育资源均等化和劳动力市场的进一步市场化对于减少为了子代福利而进行的寻租腐败行为、以及建设机会均等的和谐社会具有重要意义。     

Economic freedom and migration: A metro area-level analysis

We examine the determinants of intra-U.S. population migration at the metropolitan area level (MSA), with an emphasis on the presence of policies that are consistent with economic freedom. We are the first to produce a multivariate regression analysis of migration and economic freedom at the local level. Combining a 1993–2014 unbalanced panel of MSA-to-MSA migration data from the Internal Revenue Service with a new economic freedom index for U.S. metropolitan areas, we find that a 10% increase in economic freedom of a destination MSA, relative to the economic freedom of an origin MSA, was associated with a 27.4% increase in net migration from the origin MSA to the destination MSA. If we use mean net migration flows as a benchmark, we would expect a 10% increase in relative economic freedom to increase net migration to the destination MSA by 22 workers per year from each other MSA.     

Inequality in South Africa: The distribution of income,expenditure and earnings

This article empirically analyses the state of inequality in South Africa. International comparisons show South Africa to be among the most unequal countries in the world. The levels of income inequality and earnings inequality are analysed with a range of measures and methods. The results quantify the extremely high level of inequality in South Africa. Earnings inequality appears to be falling in recent years, with relative losses in the upper-middle parts of the earnings distribution. Decomposing income inequality by factor source reveals the importance of earnings in accounting for overall income inequality. The article concludes by observing that, internationally, significant sustained decreases in inequality rarely come about without policies aimed at achieving that, and suggests that strong policy interventions would be needed to reduce inequality in South Africa to levels that are in the range typically found internationally.     

中国居民家庭收入代际传递性分析

本文通过对父子收入代际弹性和家庭收入代际弹性的研究,发现子女收入很大程度上受到父亲收入或家庭收入的影响,证明了中国居民收入代际之间存在着较为明显的传递效应,特别是低收入群体。通过内外因分析,可以发现教育成为影响中国居民收入代际传递现象的重要因素。教育是一种重要的代际流动机制,个人教育水平提高和教育环境的公平可以使低收入群体有机会流向更高收入阶层。

Intergenerational transfer of human capital and its impact on income mobility: Evidence from China

This paper analyzes theoretically and empirically the impact of intergenerational transmission of human capital on the income mobility in China. We use a three-period overlapping-generations (OLG) model to show that the human capital transfer plays a remarkable role in determining the parent-to-offspring investment in human capital and the intergenerational elasticity of income. We then estimate a simultaneous equations model (SEM) using the 1989–2009 China Health and Nutrition Survey (CHNS) data to verify our theoretical predictions. The results show that (i) human capital, measured by health and education, is directly transmitted from one generation to the next, reflecting the parent-induced inequality of development opportunities among offspring in China; (ii) the estimated intergenerational income elasticity increases from 0.429 to 0.481 when the direct transfer of human capital is accounted for, suggesting that omitting this mechanism would overestimate China's income mobility. Our findings provide policy implications on strengthening human capital investments among the disadvantaged groups, reinforcing reforms that promote equality of opportunity, and improving the efficiency of labor markets in China.     

Convergence and Intercountry Inequality within Asia: A Combined Approach Using Decomposition Techniques and Transitional Dynamics Analysis

This study provides a comprehensive analysis of intercountry inequality and convergence in Asia by using a combined approach that is based on decomposition techniques and transitional dynamics analysis. The research is divided into three stages. First, decomposition by regional subgroups is conducted to estimate the contributions of the interregional component and the five spatial groupings to overall inequality to reveal the development of inequality in Asia. Second, the technique of decomposition by income sources is used to evaluate the relative significance of the agricultural, industrial and service sectors to facilitate formulation of industrial policy for economic development. Finally, the present study analyses the evolution of regional inequality and assesses the possibility of convergence.

Financial inclusion as a pathway to welfare enhancement and income equality: Micro-level evidence from Nigeria

While the importance of financial inclusion as a means of poverty and income inequality reduction has long been recognised, the paths to welfare enhancement and income equality through financial inclusion remain partially acknowledged. Using micro-level data on 1 750 rural Nigerian households, this study examines the finance-welfare nexus by constructing a multi-variable financial inclusion index. The results first show that financial inclusion exerts a strong positive influence on household welfare. However, the decomposition analysis shows that middle- and high-income households gain more from financial inclusion in comparison to the targeted low-income households. Second, informal livelihood strategies, such as environmental resource extraction, crops, and livestock production, revealed reduced welfare disparities across income distributions. Therefore, for financial inclusion to alleviate welfare inequality and ensure income convergence, rural financial markets must be redesigned to allow wider access to credit, specifically for low-income and vulnerable households.

Labor Market Reform, Income Inequality and Economic Growth in China

The year 1996 was a turning point both in terms of Chinese labor market reform aria m China＇s economic growth pattern. Before 1996, labor market reform was mainly implemented through adjustment of people＇s occupation and income structure. Since 1996, employment restructuring has led to differentiation in terms of employment status. Labor market reform in the former stage resulted in slow growth in wages, whereas reform in the latter stage enhanced economic efficiency. Both stages have enabled the Chinese economy to apply its comparative advantage of low labor cost. Labor market reform has also increased income disparity and, therefore, new challenges are posed in sustaining economic growth. China needs to adjust its development strategies and introduce labor market reform that can improve income equality, so as to achieve sustainable economic development.
