Opis:
This paper focusses on income inequality in Asia, its drivers and policies to combat it. It finds that income inequality has risen in most of Asia, in contrast to many other regions. While in the past, rapid growth in Asia has come with equitable distribution of the gains, more recently fastgrowing Asian economies have been unable to replicate the “growth with equity” miracle. There is a growing consensus that high levels of inequality can hamper the pace and sustainability of growth. The paper argues that policies could have a substantial effect on reversing the trend of rising inequality. It is imperative to address inequality of opportunities, in particular to broaden access to education, health, and financial services. Also, fiscal policy could combat rising inequality, including by expanding and broadening the coverage of social spending, improving tax progressivity, and boosting compliance. Further efforts to promote financial inclusion, while maintaining financial stability, can help.

Opis:
Budget control is an important element of budgeting, which is an important management accounting tool. Hence, it is necessary to recognize the need for its development. The article presents the authors’ method of measuring the variation of budget deviations. A synthetic measure of budget differentiation can be used to assess deviation levels in the budgetary control process. The method described herein provides a deviation measure that is a weighted average of the relative and absolute deviations using a convex combination of Gini coefficients, which are used as a measure of variance. The research used data including monthly budgeted and actual costs from a thermal power plant in Poland for the years 2014 through 2016. The article is a methodological approach that fits into the current research on tools used in budgetary control. In addition, the described method is integrated into the development of work on control systems.

Opis:
Measures of inequality, properly adapted, often tend to be used as a tool to address the issue of disproportionality. The most popular of them, such as the Gini or Atkinson coefficient, or entropy coefficient can, under certain circumstances, act as measures of disproportionality. However, one must specify precisely what is to be measured and interpret the results consistently. In this paper we analyze what confusion or outright errors can be committed when using inequality coefficients. The presented analysis is aimed at the Gini coefficient, however, the problem also applies to the rest of the coefficients.

Opis:
Aim: The purpose of this paper is to bring together theory and policy of (personal) income distribution on the one hand and competition policy on the other hand. Design / research: The methods used in this paper cover a brief model set-up, followed by a numerical model-calibration. Thereafter, we present a model simulation and proceed to a Gini decomposition. Herewith, we are able to demonstrate how market imperfections translate into a higher concentration of personal incomes. Conclusions / findings: Our major finding is that only a rigorous competition policy is qualified to not only correct for market imperfections, but also to fight a greater inequality of personal incomes ex-ante. Originality / value of the article: This contribution provides – to our knowledge for the first time – a simultaneous explanation for stagnating, if not falling real wages and a deteriorating development of inequality of personal incomes, as measured by the Gini coefficient ex-ante. The US economy is a case study for this double observation, but many more developed economies may follow in the foreseeable future. Limitations of the research: The implication of the research is that long before government intervenes income distribution via taxes and transfers, competition policy should correct for market imperfections and thereby reduce the inequality of personal incomes. Unfortunately, to this point, we observe a lack of meaningful macroeconomic indicators for market imperfections and hence the possibility to conduct broad econometric studies in this area of investigation.

Opis:
The governmental support program “Family 500+” can be treated as an instrument of income redistribution. Its purpose is to co-finance families with children with a monthly cash benefit, paid in cash, regardless of the income received, for each second and subsequent child. The article analyzes the impact of transfers from the program on income disparities and the extent of poverty. On the basis of data on poverty rates and income inequality measured by the Gini coefficient, it is stated that the program performs redistributive functions, which results in declining poverty, both extreme and relative in almost all types of households and socioeconomic groups, as well as decreasing the Gini coefficient. The stronger redistributive effect is, however, hampered by the too-even allocation of resources from the benefit. The program does not effectively solve the problems of any social group, leaving many people out of the target groups of support in extreme poverty.

Opis:
The aim of the article is to assess the impact of taxes on poverty and inequality in Ukraine and provide recommendations on how taxation should be used to address problems of inequality and poverty. The research methodology is based on a combination of linear regression and commitment to equity (CEQ) methodology, which was designed by Lustig to analyse the impact of taxation and social spending on inequality and poverty in individual countries. The dataset consists of data from the World Inequality Data Base and data from State Statistic Service of Ukraine. The analysis shows that income tax reform in Ukraine should not take place in the context of changing tax rates and tax periods but in the context of shifting the tax burden from the poor to the rich and preventing aggressive tax planning. Also, the results of the analysis show that the Ukrainian government’s policy of reducing free education and health services may contribute to poverty if the government does not change its redistributive policies. The article contributes to the academic literature on the impact of taxation on poverty and inequality in developing countries. The practical results obtained in the paper are useful for developing countries’ governments to design poverty- and inequality-sensitive tax policies.

Opis:
The population is continuously exposed to a background level of ionizing radiation due to the natural radioactivity and, in particular, with radon (222Rn). Radon gas has been classified as the second leading cause of lung cancer after tobacco smoke [1]. In the confined environment, radon concentration can reach harmful level and vary accordingly to many factors. Since the primary source of radon in dwellings is the subsurface, the risk assessment and reduction cannot disregard the identification of the local geology and the environmental predisposing factors. In this article, we propose a new methodology, based on the computation of the Gini coefficients at different spatial scales, to estimate the spatial correlation and the geographical variability of radon concentrations. This variability can be interpreted as a signature of the different subsurface geological conditions. The Gini coefficient computation is a statistical tool widely used to determine the degree of inhomogeneity of different kinds of distributions. We generated several simulated radon distributions, and the proposed tool has been validated by comparing the variograms based on the semi-variance computation with those ones based on the Gini coefficient. The Gini coefficient variogram is shown to be a good estimator of the inhomogeneity degree of radon concentration. Indeed, it allows to better constrain the critical distance below which the radon geological source can be considered as uniform at least for the investigated length scales of variability; it also better discriminates the fluctuations due to the environmental predisposing factors from those ones due to the random spatially uncorrelated noise.

Opis:
The article presents the life-table dispersion measures and analysis results for Poland with special regard to the process of mortality compression. The following measures were analysed: Gini coefficient, average inter-individual difference in age at death, modal age at death, inter-quartile range, standard deviation above the modal age at death, person-years lost (e-dagger) and index of mortality entropy. The empirical analysis employed data for the years 1958–2014 derived from the Human Mortality Database (HMD). The observed tendency towards reduction in the dispersion of age at death was not uniform during the 50 year span analysed and actually stagnated in certain periods. In particular, the results for the male population do not indicate a definite trend towards reduction in mortality dispersion. The results for the female population demonstrate a reduction in age dispersion at death among women over time with regard to all measures, with the modal age at death advancing towards progressively older age groups. The dispersion measures utilised in this study and the results can be used in further research on mortality compression in Poland.

Opis:
The aim of this study is the empirical analysis of the Gini coefficient decomposition by socio-economic groups in Poland from 2005 to 2013. The analysis was based on non-identifiable, individual household budget surveys data collected by Poland’s Central Statistical Office. For the purpose of this study income was defined as equivalized household disposable income, i.e. the unit of analysis is a household and household disposable income was adjusted using the OECD modi-fied equivalence scale. The Gini coefficient decomposition by socio-economic groups revealed that the residual term measuring the extent to which overall inequality is attributable to overlapping income distributions of individual socio-economic groups contributed to the greatest extent to overall income inequality in Poland during the analyzed period. The second most important factor explaining income ine-quality was the component of inequality within socio-economic groups. Income inequality be-tween socio-economic groups contributed about 28–30% to overall income inequality in Poland from 2015 to 2015. The Gini decomposition results allow to conclude, that the structure of the contribution of in-dividual socio-economic groups in Poland was the following. Employees’ households were the group with the largest, increasing contribution of weighted income variability to overall income disparities. The second group that was explaining total income disparities to the greatest extent regarding within-inequality were old-age pensioners. The remaining socio-economic groups had only a marginal impact in this regard in Poland from 2005 to 2013.
Celem pracy jest przeprowadzenie dekompozycji współczynnika Giniego ze względu na grupy społeczno-ekonomiczne w Polsce w latach 2005-2013. Badanie przeprowadzono na nieidentyfikowalnych, jednostkowych danych pochodzących z badań budżetów gospodarstw domowych GUS. W niniejszym studium przez pojęcie dochód należy rozumieć dochód do dyspozycji gospo-darstw domowych na jednostkę ekwiwalentną, tj. za badaną jednostkę przyjęto gospodarstwo domowe, za dochód – dochód do dyspozycji, przy czym zastosowano zmodyfikowaną skalę ekwiwalentności OECD. Dekompozycja współczynnika Giniego według grup społeczno-ekonomicznych pokazała, że największy wkład w kształtowanie się nierówności dochodów ogółem w Polsce w badanym okresie miał składnik resztkowy, czyli efekt wynikający z nakładania się dystrybucji dochodów poszczególnych grup społeczno-ekonomicznych. Drugim, co do istotności czynnikiem wyjaśniającym zróżnicowanie dochodów zgodnie z dekompozycją współczynnika Giniego według grup społeczno-ekonomicznych były nierówności wewnątrzgrupowe. Wkład nierówności międzygrupowych stanowił około 28-30% zróżnicowania dochodów ogółem w Polsce w badanym okresie. Uzyskane wyniki pozwoliły stwierdzić, że w badanym okresie struktura wkładu poszczegól-nych grup społeczno-ekonomicznych w wyjaśnianiu nierówności dochodów ogółem w Polsce kształtowała się następująco. Do grupy o największym, rosnącym wkładzie nierówności dochodów ważonych udziałami w populacji i dochodzie ogółem należały gospodarstwa domowe pracowników. Ważone zróżnicowanie dochodów dla gospodarstw domowych emerytów wyjaśniało nierówności ogółem w drugiej kolejności spośród badanych grup ekonomiczno-społecznych, mimo że grupa ta charakteryzowała się najniższym zróżnicowaniem dochodów w badanym okresie. Ważone nierówności dochodów pozostałych grup społeczno-ekonomicznych miały bardzo niewielkie znaczenie, jeśli chodzi o wkład w zróżnicowanie dochodów ogółem w Polsce w latach 2005–2013.

Opis:
In the presented paper authors attempt to analyze the differences in the use of computers and the Internet in particular voivodships, places of residence and in different socio-economic groups in Poland in the years 2011, 2013 and 2015. To this purpose authors used data on the diagnosis of conditions and the quality of life of Polish people [8]. Gini's indicators and the Lorenz curve were used to visualize the differences in the use of computers and the Internet. The results showed that the greatest variation in the use of Internet and Computers was between students/learners, private entrepreneurs and the pensioners, annuitants and farmers. In the place of residence and the voivodeship, there were no significant differences in the use of these two above technologies.
