Perspectives on poverty and income inequality in Brazil

Exploratory analysis of the advance tabulations of the 1980 Brazilian demographic census suggests the proportion of the population in poverty fell during the decade 1970–1980. The degree of inequality of the distribution of the income of individuals apparently remained about the same from 1970 to 1980, after rising in the 1960s. This near-constancy of the overall inequality of income distribution resulted from two offsetting changes: a narrowing of the gap between rural and urban incomes, and greater inequality within the rural sector.     

The impact of education on income inequality and intergenerational mobility

This paper analyses the effects of innate ability, compulsory education (grades 1–9), and non-compulsory education (grades 10–12 and higher education) on inequality and intergenerational mobility of income, by constructing a four-period overlapping-generation model. We find that innate ability and family investment in early education play important roles in explaining income inequality and intergenerational income mobility. Though children from the wealthiest families are only 1.36 times ‘smarter’ that those from the poorest, the gap in human capital expands to 2.35 at the end of compulsory education and to 2.89 at the end of non-compulsory education. One important reason for the increase is that poor families invest relatively less in children's early education than do wealthy families; therefore, their children attend lower-quality schools, which results in them being much less likely to participate in higher education. By simulating policy experiments for different types of government education expenditure, we find that direct subsidies to poor parents are the most efficient and effective policy for mitigating poor families' budget constraints with regard to early-education investment in their children.     

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。     

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.     

Carbon emissions and income inequality

We find that the distribution of income matters to aggregatecarbon dioxide emissions and hence global warming. Higher inequality,both between and within countries is associated with lower carbonemissions at given average incomes. We also confirm that economicgrowth generally comes with higher emissions. Thus our resultssuggest that trade-offs exist between climate control (on theone hand) and both social equity and economic growth (on theother). However, economic growth improves the trade off withequity, and lower inequality improves the trade off with growth.By combining growth with equity, more pro-poor growth processesyield better longer-term trajectories of carbon emissions.     

Relative income position,individual and social income satisfaction,and income inequality

Summary The survival probability as estimated by an individual is,ceteris paribus supposed to depend on his relative income position in a set of reference incomes. The relative income position is thus defined in close connection to the preference formation theory of Kapteyn. It is shown that then this survival probability, called ‘utility,’ may be equated to the relative income position. A nice result of this approach is the possibility to formulate a utilitarian welfare function, which leads to the definition of income inequality measures. It is shown that the use of sets of reference incomes may lead to considerably smaller measured inequality.     

Dynamics of income inequality in Sweden

This paper investigates income inequality among individuals in Sweden overtime using generalized entropy measures in short-run (annual) and long-run (medium term) from 1978 to 1990. The results suggest that short-run inequality tends to decrease with fluctuations, partially due to transitory components. Long-run inequality declines in early years due to smoothing of transitory components. Further decline in long-run inequality is due to actual equalization. Gender, cohort, marital status, and region are used to investigate their implications. Between-group inequality due to gender and cohort are shown to be significant part of inequality. Within-group equalizations are generally more pronounced. Distinct group specific differences are observed.

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.     

Crime and income inequality: An economic approach

Conclusion When a given pie is redivided in a less equalitarian manner, it is uncertain whether those already undertaking illegal activity will increase or decrease their activities, since the return to illegal activities is countered by the loss due to punishment (which is more painful to a criminal who failed) on one hand, and from the cost of the sacrifice of utility from legitimate activities on the other hand.If the absolute level of wealth remains constant but relative position declines, an incentive is generated to re-establish a person's standing by joining the crime industry. This is certainly the case at the margin for those close to the boundary of joining, i.e., those who are almost indifferent between joining or remaining within the legal framework.Assuming an individual is already participating in illegal activities, the effect of either an absolute or relative change in his level of wealth on his level of illegal activities is indeterminate. This applies both to the case where the total wealth of the society is fixed and the share of the pie going to the rich rises and the case where the total pie rose but the entire gain went only to the rich.In summary, it has been shown that an increase in wealth inequality has an indeterminate outcome both with respect to the decision of the poor on whether or not to enter the crime industry and with respect to the decision of those already participating in illegal pursuits to increase or decrease their level of activity. This conclusion is somewhat contrary to the general consensus of the literature, which appears to hold that increases in wealth inequality will tend to increase both the level of participation in the crime industry and the level of output within the industry.     

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.     

Towards a better measure of income inequality in Indonesia

Indonesia has experienced significant economic growth in recent years (on average, 5% in 2000–08), but many people are still living in poverty. Income inequality, as measured by the official Gini coefficient, has also increased. This paper evaluates household income and income inequality in Indonesia, assessing both market and non-market income to reach a more accurate measure of how actual income affects living standards. We find that if household income considers non-market income, income distribution is significantly more balanced, the coefficient of income inequality falls from 0.41 to 0.21 and the income share of the population's poorest deciles increases more than fivefold. The results suggest that market income alone is a misleading measure of income distribution in Indonesia.     

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.     

Education expansion,assortative marriage,and income inequality in China

In this paper, we study the pattern of assortative marriage in China since 1990 and its impact on income inequality. The results indicate that men in China are increasingly likely to marry women of similar education levels. We calculate the counterfactual income inequality that would prevail if marriages were randomly matched in terms of education. In 2005, China's overall Gini coefficient of household income per capita would decline from 0.512 to 0.476 if marriages were randomly matched. In urban areas, assortative marriage in education increased the Gini coefficients from 0.321 to 0.338 in 2009. The decomposition exercise shows that the rising returns to education contribute most to the increase in income inequality in urban areas between 1990 and 2009, while the change in marriage assortativeness plays a minor role.     

Trade liberalization and income inequality: The case for Pakistan

Trade liberalization policies have been adopted by many developing countries to increase economic growth and reduce poverty. While the positive relationship between trade liberalization and economic growth is generally well accepted, the impact of trade liberalization on poverty and income inequality is still unclear. The objective of this paper is to use real data and real trade agreements of the state of Pakistan, to examine the predictions made by trade models about the impact of trade liberalization on income inequality. To illustrate, the impacts of several alternative bilateral and regional free trade agreements are simulated on household income and income inequality in Pakistan. The results show that trade liberalization does not always lead to a decline in income inequality in the short run. Trade agreements that do improve income equality, favor agriculture and often hinge on a decline in urban and non-farm household income. In the long run, changes in income equality are more positive, suggesting that efforts might best be applied towards improving the mobility of labor and capital.     

The impact of microfinance on poverty and income inequality in developing countries

Economic growth in developing countries provides an opportunity to accelerate progress towards the UN Sustainable Development Goals (SDGs). However, in reality, the number of people living in extreme poverty remains unacceptably high. Utilising the experiences of 34 developing countries for the period 2009 to 2016, the role of microfinance on poverty in these countries is examined. The results imply that the degree to which the existing forms of microfinance effectively reduce extreme poverty is less workable in developing countries, particularly when the hardcore poor are likely being deprived of receiving access to microfinance. It is suggested that governments may need to revise the structure and strategy of microfinance to be more hardcore poor oriented. The hardcore poor have needs beyond pure monetary assistance. More hand‐holding types of assistance are needed as most are also poor in respect of literacy, assets, and skills.     

The long-term evolution of national income inequality and rural poverty in China

Using the five waves of the China Household Income Project surveys conducted during 1988–2013, we investigate long-term changes in national income inequality and rural poverty in China. National income inequality rose markedly to 2007 and thereafter fell slightly. Income growth was widely shared, but inequality increased because the high-income percentiles had faster income growth than lower percentiles and because the gap between urban and rural household incomes widened. The fall in income inequality after 2007 reflects faster income growth among low-income percentiles and the impacts of newly introduced redistributive policies. The paper also finds a considerable, ongoing poverty reduction in rural China. A poverty decomposition analysis indicates that this rural poverty reduction was mostly due to income growth rather than redistribution.     

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.
