Opis:
Research background: In applied welfare economics, the constant relative inequality aversion function is routinely used as the model of a social decisionmaker?s or a society?s preferences over income distributions. This function is entirely determined by the parameter, ?, of inequality aversion. However, there is no authoritative answer to the question of what the range of ? an analyst should select for empirical work. Purpose of the article: The aim of this paper is elaborating the method of deriving ? from a parametric distribution of disposable incomes. Methods: We assume that households? disposable incomes obey the generalised beta distribution of the second kind GB2(a,b,p,q). We have proved that, under this assumption, the social welfare function exists if and only if ? belongs to (0,ap+1) interval. The midpoint ?mid of this interval specifies the inequality aversion of the median social-decisionmaker. Findings & Value added: The maximum likelihood estimator of ?mid has been developed. Inequality aversion for Poland 1998?2015 has been estimated. If inequality is calculated on the basis of disposable incomes, the standard inequality?development relationship might be complemented by inequality aversion. The ?augmented? inequality?development relationship reveals new phenomena; for instance, the stage of economic development might matter when assessing the impact of inequality aversion on income inequality.

Opis:
Research background: In the distributive analysis, the constant relative inequality aversion utility function is a standard tool for ethical judgements of income distributions. The sole parameter ? of this function expresses a society?s aversion to inequality. However, the profession has not committed to the range of ?. When assessing inequality and other welfare characteristics, analysts assume an arbitrary level of ?, common to all countries and years. This assumption seems unjustified. Purpose of the article: This paper aims to estimate the parameter ? for each country and year individually using datasets from the Luxembourg Income Study Database in all available years, which dates back to the 1970s. Methods: We utilise the method of estimating ?, which assumes the generalised beta of the second kind distribution of incomes. The estimator of ? is derived from the mathematical condition of the existence of the social welfare function.  Findings & value added: We have elaborated an ?atlas? of  388 estimates of ? for 55 countries across time. Inequality aversion is country-year specific, with a minimum of 0.97 and a maximum of 3.8. Ninety per cent of all estimates are less than 2.5. Inequality aversion is negatively correlated with income inequality, but it is independent of economic development. Thus, inequality aversion appears as an additional dimension of the classical inequality-development relationship. This article contributes to solving a fundamental problem of Welfare Economics: directly measuring the social utility of income (welfare) function. The estimates of ? for 55 countries imply a complete knowledge of these countries' constant relative inequality aversion utility functions.

Opis:
Research background: In Economics, the concept of inequality aversion corresponds with the concept of risk aversion in the literature on making decision under uncertainty. The risk aversion is estimated on the basis of subjective reactions of people to various lottery prospects. In Economics, however, an efficient method of estimating inequality aversion has not been developed yet. Purpose of the article: The main aim of this paper is to develop the method of estimating inequality aversion. Methods: The method is based on two income thresholds which are subjectively assessed by surveyed respondents. Given the level of household income, just noticeable worsening of household welfare is perceived below the first threshold, whereas just noticeable improvement of household welfare is perceived above the second threshold. The thresholds make possible effective calculations of the parameter of the Arrow-Pratt’s constant inequality aversion utility function. In this way, an individual utility of income becomes an empirically observable economic phenomenon. Findings & Value added: In this paper, two theorems are proved which provide the guidance on how to identify a proper version of the above function. The proposed method is tested on the basis of statistical data from the archival survey conducted among Polish households in 1999. The statistical analysis of those data reveals the appearance of convex utility functions as well as concave ones. Nevertheless, the prevailing part of the Polish society exhibited inequality aversion in the year 1999. Another result of this paper is that inequality aversion diminishes as income increases.

Opis:
Research background: Income inequality has risen sharply since the 1990s, despite the increase in the average size of redistribution in countries representing different welfare state models. The problem of increasing income inequality is currently a challenge for the EU economies, not only with well-established liberal traditions, but also with conservative and social-democratic ones. Therefore, it is worth conducting research on the redistributive effects of fiscal policy. Purpose of the article: The article aims to show the redistributive effects of fiscal policy, paying particular attention to the most characteristic trends in redistribution, which are responsible for the growing income inequality. An overview of the fiscal instruments ? mainly personal income tax and benefit systems ? along with an empirical research on their potential impact on income inequality, allows for conclusions to be drawn about the effectiveness of redistributive policy in the EU countries. Methods: Both descriptive analysis and panel data analysis is implemented to examine the effectiveness of redistributive policy in tackling income inequality in the EU?28 countries in years 2005?2017. Findings & value added: Based on the panel analysis, it has been found that social transfers were much more effective than direct taxes in combating income inequality. In addition, the largest increase in income inequality ? as previously assumed ? was observed in the liberal welfare states, while the smallest in the social democratic welfare states. The empirical analysis extends the existing knowledge on main weaknesses of fiscal welfare state, indicating the required changes that may improve both its equity and efficiency.

Opis:
Research background: Income inequality and poverty attract a lot of attention among politicians, activists as well as scientists, who are trying to find a solution to these socio-economic problems. State intervention is commonly expected in this field, however, there is no agreement about the most efficient methods and instruments, as well as about the scale of public expenditure for the purpose of limiting poverty and inequality. Purpose of the article: The aim of the paper is to specify efficiency of government social spending in reducing problems of poverty and income inequality in the EU countries. Moreover, the attention is paid to changes in the efficiency in a period of the 2007 crisis occurrence and its overcoming and to sources of the changes. Methods: To fulfill the main goal of the paper, the DEA method is used, which enables to compare the social efficiency of the EU countries. The Malmquist index is also calculated and decomposed to identify changes in the efficiency and their sources in the crisis period. Data used in the analyses were obtained from Eurostat and OECD databases and cover the period from 2007 to 2016 year. Findings & Value added: The main findings of the paper shed some light on the differences in social efficiency of government spending in the EU countries. Generally, the countries with a higher level of social spending are also those with lower efficiency in inequality reduction, however, the relationship doesn?t appear for poverty alleviation. Thus, the research suggests some substitution between the scale and the efficiency of social spending, at least for the inequality dimension. Moreover, some differences in a social model can be found between the countries of the  South and of the North: the countries of the South focus their social policy mainly on inequality reduction, while the Scandinavian countries as well as some other affluent societies direct their public support mainly on poverty alleviation. The research also shows that in the crisis period decreases in efficiency concerned mainly the poverty dimension. It reflects the fact that the poor were the losers of the crisis in favor of the middle classes. The efficiency losses were induced by negative changes in the current usage of public sources, while institutional reforms positively influenced the efficiency.

Research background: According to classical labor economics, wage differences among regions of a country that has free-factor mobility should eventually vanish. However, the level of wage inequality among Mexican territories is increasing. The nature and causes of this discrepancy are worth identifying. Purpose of the article: To identify the spatial relationship of wage inequality that existed in the Mexican metropolitan system during the years 2010 and 2015. Methods: We develop a model of wages that considers the interaction between spatial units within a region. Then, we specify a spatial autoregressive model with the average wage per municipality as a dependent variable. This variable is spatially lagged along with other controls such as productivity, schooling, and migration. We combine data from population and economic censuses. Then, we perform a quantile regression to estimate the spatial effect of wage in a region upon quartiles of the wage distribution. Findings & value added: Wage inequality increases within a given region when the average wage increases in one of said region?s municipalities. This phenomenon occurs because in municipalities that are neighbors of the one that enjoys a wage increase, the average wage tends to decrease. The impact is larger in those municipalities whose average wage is in the lower range of the regional wage distribution. Wage inequality is also increased by internal migration and increased productivity. These latter findings are some of the first for Mexico at this aggregation level. A novel aspect of our study is its use of territory as an observation unit for which statistics from population and economic censuses are combined to draw inferences about spatial inequality.

Opis:
Research background: The reduction lately observed in interregional differences in the per capita income in Russia requires some clarification of the reasons. One possible way to do this could be decomposition of interregional inequality in personal incomes by income sources, i.e.: wages and salaries, property incomes, social transfers, entrepreneurship incomes and revenues from informal activities. Purpose of the article: The objective of this research is identification of the character, direction and degree of influence of various income sources on interregional inequality and convergence of Russian regions by their per capita income in 2001?2014.  Methods: We brought personal incomes in the regions to a comparable level using the relative cost of fixed consumer basket. Then we applied the population-weighted Gini coefficient, coefficient of variation, and the Theil index to measure the interregional inequality in personal incomes in dynamics. Further usage of various techniques of inequality decomposition allowed us to evaluate contribution of different types of income to the Russian regions? convergence across time. Findings & value added: Various types of income demonstrated different paths of interregional inequality, changes in interaction and in the shares of total income, which altogether influenced spatial inequality. Wages and salaries showed the largest and growing impact on inequality. The contribution of informal incomes to the overall inequality was the second largest, but diminishing and negatively interacting with other unevenly distributed types of income; thereby they provided more than half of the total interregional convergence. Entrepreneurship incomes revealed slightly decreasing influence on inequality, which was mainly neutralized by their reduction in the share of total income. Social transfers demonstrated the largest smoothing effect, however, their contribution to convergence was exhausted. Property incomes evidenced the greatest enhancing impact on inequality especially in the period of recovery. Additionally, informal incomes played the role of substitutes for formal incomes providing self-replicating mechanisms for reducing inequality in Russia.

Opis:
The relationship between the public health status and income inequality has been taken into consideration in the last two decades. One of the important questions in this regard is that whether the changes in income inequality will lead to changes in health indicators or not. To answer this question, life expectancy is used as a health indicator and the Gini coefficient is used as an income inequality indicator. In this study, the relationship between income inequality and the public health has been investigated by panel data in Eviews software during 2000–2011 in 65 low-and middle-income countries. By using panel data and considering fixed effects and heterogeneity of sections, the relationship between income inequality and public health status is a significant negative relationship.

Research background: In the actual sizable populations of households, the standard microeconomic concept of equivalence scales is intractable since its necessary condition of equality of household welfare levels is unlikely to be fulfilled. Purpose of the article: This paper aims to develop a concept of an equivalence scale, which can be suitable for continuous distributions of expenditures in the population. Methods: Using household welfare intervals, we get the random equivalence scale (RES) as the ratio of expenditure distributions of the compared populations of households. Findings & value added: We derive the parametric distribution of RES for the lognormal distributions of expenditures. The truncated distribution of RES is applied to account for possible economies of scale in the household size. A society?s inequality aversion can be helpful when selecting a single equivalence scale. We estimate RES for Poland using microdata on expenditures and subjective assessments of household welfare intervals. The estimated equivalence scales turned out to be very flat and dependent on welfare.

The presented article uses the method of non-weighted average absolute deviation for expressing income inequality in 11 selected Central and Eastern European Countries. Specifically, the analysis of income inequality is done for Poland, the Czech Republic, the Slovak Republic, Austria, Slovenia, Hungary, Romania, Bulgaria, Latvia, Lithuania and Estonia. Based on the determination of income inequality in the article an analysis is made concerning the development of income inequality, including the subsequent inter-regional comparison in the context of the degree of income inequality in a given human society and economy. The text of this article is organized in 4 parts, after Introduction follows the analytic chapter where, primarily, the method of non-weighted average absolute deviation is explained. The third part contains the empirical analysis of income inequality, and the Conclusion highlights some major conclusions of detailed analysis made in Chapter 3. The analysis of income distribution of 11 European households between years 2005-2013 and its order is made in deciles basing on empirical data from the Statistics on Living Conditions and Welfare published by Eurostat.

Opis:
Research background: Economic crisis hit all the European Union Member States hard, with the impact of crisis varying considerably. The low growth performance in the EU has increased concerns regarding an increasing wage dispersion, income inequality at large, and social exclusion in line with poverty. Inequality should be seen as a cornerstone of both sustainable and inclusive growth under the Europe 2020 Strategy. Social inequality in the EU is a real problem, which hampers sustainable economic growth. Purpose of the article: The purpose of this study is to introduce evaluation of social development convergence and divergence trends between the EU Member States in the context of the Europe 2020 Strategy. The study gives an outline of the issues of the labour market and income disparities and poverty. Policymakers must be clear about what social objectives they are aiming to achieve, therefore special attention is paid to headline national goals of the Europe 2020 Strategy. Methods: The main task of this study is to assess social dimension and inequalities problems in the EU27 by applying Data Envelopment Analysis method, resp. time-series dynamic efficiency analysis in the form of output-oriented Malmquist Productivity Index. This study contains changes of key social equality indicators related to the Europe 2020 Strategy and compares objectives and general outlines of period 2010-2015, as well as the impact on national economics and living conditions. Findings & value added: Results contain elements of typology premises of the EU28 and point to a large diversity in inequality patterns, as the Author observes both increases and decreases in inequality at the EU level. Recent changes in social inequality have been associated with the business cycle, particularly with the accessibility of the labour market and, of course, with income inequality. Additionally, the development challenges are discussed for improvement of the socioeconomic well-being of the EU and to avoid social disparities.

Research background: Intensive economic growth in Russian regions during recent decades has been associated with numerous environmental issues, particularly increasing CO2 emissions, as well as income inequality. To achieve sustainable development, it is necessary to resolve these issues. Purpose of the article: To shed light on the impact of income inequality on CO2 emissions based on Russian regional data covering the years 2004?2018. Methods: Gini index and decile dispersion ratio are used to measure income inequality. To study the impact of income inequality on CO2 emissions in the Russian regions, we estimate econometric models with fixed and random effects and apply GMM method. We test the hypothesis of the environmental Kuznets curve to determine the impact of economic growth on CO2 emissions. Findings & value added: The results show that CO2 emissions increase in tandem with growth in income inequality between 10% of people with the lowest income and 10% of people with the highest income. Simultaneously, CO2 emissions decrease with growth of Gini coefficient. The hypothesis of the Environmental Kuznets Curve was confirmed based on GMM method. Our findings underscore that the activities of the extraction and manufacturing sectors, as well as energy consumption, increase CO2 emissions. The chief significance of this paper is the finding that large income gap between extremely rich and extremely poor population cohorts increases CO2 emissions. This implies that economic policy aimed at reducing income inequality in Russian regions will also reduce CO2 emissions, especially if accompanied by increased use of environmentally friendly technologies. From the international perspective, our research can be extended to study other countries and regions.

Research background: The research is based on the assumption that the sectoral structure of economy has a significant impact on the level and dynamics of sub-federal budget tax revenues. It distinguishes the following sectoral determinants of tax revenues in regions: the levels of tax return and tax absorption, inflation and economic growth in various economic activities. Purpose of the article: We aimed at assessment of contribution of economic activities and their determinants to the increase in tax revenues of sub-federal budgets of the Russian Federation in 2011?2015 compared to 2006?2010. Methods: Development of a four-factor additive-multiplicative model of the tax revenue formation in regions, application of the proportional and logarithm methods of factor analysis to assessment of contribution of various activities and their determinants to increase in tax revenues of sub-federal budgets, evaluation of inter-regional inequality of tax revenues growth based on the weighted coefficient of variation, and decomposition of this inequality using the A. Shorrocks technique. Findings & Value added: We identified activities that made the largest contribution to the increase in tax revenues of the Russian sub-federal budgets. We found that the inflation factor had a predominant positive effect on the growth of tax revenues, while the contribution of the economic growth factor was 4 times less; however, the situation in various activities differed significantly. Generally, changes of sectoral levels of tax return and tax absorption influenced negatively the regional tax revenues. In addition, they moved in opposite direction in the regions. Ultimately, the uneven change in tax returns and price levels in the mining and manufacturing activities of Russian regions made the greatest contribution to inter-regional inequality of the growth of sub-federal budgets tax revenues.
