EFFECTS OF GOVERNMENT POLICIES ON URBAN AND RURAL INCOME INEQUALITY

We use three conventional inequality indices—the Gini, the coefficient of variation of income, and the relative mean deviation of income—and the Atkinson index to examine the effect of income tax rates, the minimum wage, and all the major government welfare and transfer programs on the evolution of income inequality for rural and urban areas by state from 1981 to 1997. We find that these programs have qualitatively similar but quantitatively different effects on urban and rural areas. Most importantly, taxes are more effective in redistributing income in urban than in rural areas, while welfare and other government transfer programs play a larger role in rural areas.     

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.     

INCOME STRATIFICATION AND INCOME INEQUALITY

This paper develops a new index of stratification that highlights the distinction between inequality and stratification. The stratification index captures the extent to which population subgroups occupy distinct strata within an overall distribution. The indices are group specific and control for group size. A weighted sum of group stratification indices is the third term that, together with between-group inequality and a weighted sum of within-group inequality adds to the overall Gini index of inequality.     

INCOME INEQUALITY AND POLITICAL POLARIZATION AND FRACTURALIZATION:AN EMPIRICAL INVESTIGATION OF SOME EUROPEAN COUNTRIES

This paper investigates the relationship between economic inequality and the distribution of votes among political parties, namely political polarization and fracturalization. Economic inequality is captured by the Gini index, whereas new measures of political polarization and fracturalization are offered. This is the first paper to calculate political polarization and fracturalization indices by a methodology previously used for ethnic, religious and linguistic polarization and fracturalization. Empirical analysis uses data for 17 European countries and for three decades, 1980s, 1990s and 2000s. It is shown that increased income inequality increases political party polarization and reduces fracturalization and that political party polarization decreases with increased GDP per capita.     

DYNAMIC STATUS EFFECTS,SAVINGS, AND INCOME INEQUALITY

This article advances the hypothesis that the intensity of status preferences depends negatively on the average wealth of society (endogenous dynamic status effect), in accordance with empirical evidence. Our theory replicates the contradictory historical facts of an increasing saving rate along with declining returns to capital over time. By affecting the dynamics of the saving rate, the dynamic status effect raises inequality, thereby providing a behavioral mechanism for the observed diverse dynamics of income inequality across countries. In countries in which the dynamic status effect is strong (weak), inequality rises (declines) over time in response to a positive productivity shock.     

A META‐ANALYSIS ON THE RELATIONSHIP BETWEEN INCOME INEQUALITY AND ECONOMIC GROWTH

In recent years there is a growing interest in determining the impact of inequality on economic growth. Theoretical papers as well as empirical applications have, however, produced controversial results. Although there is a considerable part of the literature that considers inequality detrimental to growth, more recent studies have challenged this result and found a positive effect of inequality on growth. In this paper, we provide a contribution to the empirical puzzle by using meta‐analysis to systematically describe, identify and analyse the variation in outcomes of empirical studies. We find that estimation methods, data quality and sample coverage systematically affect the results. The results point out that it will be particularly useful to increasingly focus research on determining the impact of income inequality on economic growth using single‐country data at the regional level, or a relatively homogeneous set of countries with adequate controls for country‐wide differences in economic, social and institutional characteristics.     

LAND DISTRIBUTION INEQUALITY AND ECONOMIC GROWTH: TRANSMISSION CHANNELS AND EFFECTS

Abstract.  Land reform in Asian countries is often mentioned as one explanation for the successful economic performance of several Asian countries. Latin American countries did not have land reform and therefore have had lower economic growth. However, this legitimate guess has only scarce evidences. We use a new analytical method to investigate some plausible channels and effects, and we find supportive evidences that part of the regional differential in economic performance of the East Asian and Latin American regions can be explained by their difference in land distribution inequality.     

FALLING LABOR INCOME INEQUALITY IN KOREA'S ECONOMIC GROWTH: PATTERNS AND UNDERLYING CAUSES

Over the last twenty-five years, the economy of the Republic of Korea achieved a remarkable growth rate of 7 percent per year in real per capita income, causing it to be labeled, justifiably, as a "miracle economy." This exceptional economic growth has beenpp accompanied by an even more exceptional fall m labor income inequality. Using a newly-developed methodology, we use data from Korea's Occupational Wage Surveys to quantify the importance of various factors that have contributed to the fall in labor income inequality in Korea. We find the most important factors explaining the level of income inequality are job tenure, gender, years of education, and occupation, while those that are most important in explaining the change in income inequality are years of education, industry, occupation, and potential experience.

LIFE SATISFACTION AND INCOME INEQUALITY

Do people care about income inequality and does income inequality affect subjective well‐being? Welfare theories can predict either a positive or a negative impact of income inequality on subjective well‐being and empirical research has found evidence of a positive, negative, or non‐significant relation. This paper attempts to determine some of the possible causes of such empirical heterogeneity. Using a very large sample of world citizens we test the consistency of the effect of income inequality in predicting life satisfaction. We find that income inequality has a negative and significant effect on life satisfaction. This result is robust to changes of regressors and estimation choices and also persists across different income groups and across different types of countries. However, this relation is easily obscured or reversed by multicollinearity generated by the use of country and year fixed effects. This is particularly true if the number of data points for inequality is small, which is a common feature of cross‐country or longitudinal studies.     

INCOME INEQUALITY AND POVERTY: SOME PROBLEMS

In an important recent book dealing with the measurement of income inequality with particular reference to poverty,¹ Prof. N. Kakwani derives several poverty indices, investigates the effect of negative income tax schemes with the help of those indices and gives a numerical illustration based on Malaysian data.
The aim of this note is to point out some logical flaws in his argument. Some of the ideas expressed in the part of his book we are concerned with have been disseminated for some time now² and referred to in subsequent literature;³ yet their shortcomings do not seem to have attracted anyone's attention. The introductory section gives a concise presentation of the relevant part of Kakwani's contribution. The next two sections deal with some problems with his approach.     

INCOME AND WEALTH INEQUALITY: EVIDENCE AND POLICY IMPLICATIONS

Drawing on the author's work, this lecture presents evidence on U.S. income and wealth inequality. It presents series for top income and wealth shares, and the distribution of economic growth by income groups. It discusses the mechanisms behind the evolution of U.S. income and wealth inequality from historical and comparative perspectives. It analyzes the role of public policy and in particular taxation in the evolution of inequality. (JEL D31, F66, J24)     

FISCAL CONSOLIDATION PROGRAMS AND INCOME INEQUALITY

We document a strong empirical relationship between higher income inequality and stronger recessive impacts of fiscal consolidation episodes across time and space. To explain this finding, we develop a life‐cycle economy with uninsurable income risk. We calibrate our model to match key characteristics of several European economies, including inequality and fiscal structures, and study the effects of fiscal consolidation programs. In our model, higher income risk induces precautionary savings behavior, which decreases the proportion of credit‐constrained agents in the economy. These agents have less elastic labor supply responses to fiscal consolidations, which explain the correlation with inequality in the data.     

股市发展与收入分配不平等

股市发展与收入分配状况的关系是金融理论界和业界广泛关注的问题之一。本文构造全球33个国家从1988年至2013年有关股市发展和收入分配不平等的面板数据,实证研究各国股市发展及自由化改革对其收入分配不平等程度的影响及内在机理。研究发现：首先,一国股市规模越大,由于门槛效应的存在,其收入分配状况趋于恶化,而流动性的提升将在一定程度上改善其收入分配状况。其次,一国股市的发展对不同收入阶层存在不同的影响。最后,股市自由化前后,股市对收入分配状况的影响存在显著差异：股市自由化之后,股市规模的扩大和股市流动性的提升将在一定程度上改善收入分配状况。     

DISTRIBUTIONS OF REAL INCOME: WITHIN COUNTRIES AND BY WORLD INCOME CLASSES

Income and expenditure data from 14 countries (representing one-third of the world's population), mostly from the 1970s, are used to construct national income distributions and , after normalizing by purchasing power parities, to construct a "world" distribution of real income. The density of real-income equivalent groups (socio-economic classes) across countries is measured for the "affluent," the "well-off," and the "poor." In comparison with earlier studies, most national distributions of income seem to have been improving, the numbers of those in poverty (based on real income) are lower, and, most important (and disturbing for some) is that the "affluent" class (and those above "middle class" income levels) has (prematurely) swelled in a number of developing countries.     

INEQUALITY AND PANEL INCOME CHANGES: CONDITIONS FOR POSSIBILITIES AND IMPOSSIBILITIES

Income changes in an economy are usually assessed through the changes over time in cross-sectional variables such as economy-wide inequality. An alternative is to use panel data to gauge income changes among identified income recipients. In this article, we analyze these two approaches taken together, each measured in multiple ways. We establish that under specific conditions, it is impossible to have falling inequality together with divergent panel income changes. We also provide conditions explaining when rising inequality can arise together with convergent panel changes. We provide the intuition behind these results and show when such results fail to hold.
