We prove that the double inequality Mp(a,b)<X(a,b)<Mq(a,b) holds for all a,b>0 with a≠b if and only if p≤1/3 and q≥log 2/(1+log 2)=0.4093…, where X(a,b) and Mr(a,b) are the Sándor and rth power means ...of a and b, respectively.
The subject of discussion in the article is housing inequality in a region on the example of cities in Kirov region. The author analyzes the content components of housing inequality, environmental ...and personal resources that promote and impede the preservation and improvement of housing status. The empirical base of the study was the results of a semi-formalized survey of citizens and expert interviews with realtors conducted in summer 2018 in three cities of Kirov region: Kirov, Vyatskiye Polyany and Kirovo-Chepetsk. The housing "portraits" of citizens are presented, the specificity of the housing plans, practices and self-identification of residents of regional and district cities is analyzed. The empirical study leads to the conclusion that the housing mentality of citizens is characterized by "healthy optimism" and relatively low demands, since the majority of respondents, even against the background of modest opportunities and a "bunch" of housing problems, highly appreciate the quality of their housing and are generally satisfied with its condition. Housing mobility of citizens is mainly reduced to movements within the same housing class. Radical improvements at the expense of available resources can afford only a few, although the population is increasingly using borrowed funds for the arrangement.
In the present paper, we aim to prove a new lemma and quantum Simpson’s type inequalities for functions of two variables having convexity on co-ordinates over α , β × ψ , ϕ . Moreover, our ...deduction introduce new direction as well as validate the previous results.
Social scientists have been aiming to calculate a “subjective income Gini coefficient”of survey respondents that would describe their beliefs about income inequality in their country. Niehues ...(Subjective perceptions of inequality and redistributive preferences: an international comparison, Cologne Institute for Economic Research, IWTRENDS Discussion Paper, 2014) derives this estimate from respondents’ beliefs about the relative sizes of different social classes (answers to “shape of society” questions), while Kuhn (The individual perception of wage inequality: a measurement framework and some empirical evidence, Technical report, Institute of Labor Economics (IZA), 2015) estimates it using beliefs about the pay structure. We combine their efforts to calculate what we call a twofold subjective Gini coefficient, which incorporates both pieces of information independently from one another. We present the country-level distribution of perceived and desired twofold subjective Gini coefficients using the ISSP Social Inequality V survey (ISSP Research Group in International social survey programme: social inequality v—issp 2019, 2019.

). Accounting for both subjective class structure and pay structure yields much lower perceived and desired levels of inequality. At the country level the averages of the twofold subjective Gini coefficients are closer to actual income Gini coefficients than the previous measures. At the individual level the twofold subjective Gini coefficients are better predictors of the individual’s verbal assessment of inequality and their preferences towards redistribution.
In this paper, we prove several new Hardy type inequalities (such as the weighted Hardy inequality, weighted Rellich inequality, critical Hardy inequality and critical Rellich inequality) related to ...the radial derivation (i.e., the derivation along the geodesic curves) on the Cartan–Hadamard manifolds. By Gauss lemma, our new Hardy inequalities are stronger than the classical ones. We also establish the improvements of these inequalities in terms of sectional curvature of the underlying manifolds which illustrate the effect of curvature to these inequalities. Furthermore, we obtain some improvements of Hardy and Rellich inequalities on the hyperbolic space ℍn. Especially, we show that our new Rellich inequalities are indeed stronger than the classical ones on the hyperbolic space ℍn.
A partir de consideraçöes de natureza económica, baseada na chamada economia da desigualdade, o artigo busca examinar, a luz do princípio constitucional da igualdade tributaria, o limite de imunidade ...instituido pela EC 41/2003, no tocante aos proventos dos inativos do serviço público - RPPS -, em valor absoluto igual ao do regime geral de previdencia - RGPS -, de que trata a EC 20/1998 e os reflexos na EC 47/2005, que dobrou o referido limite para os portadores de doença incapacitante. Para tanto, examina-se a natureza tributaria contraprestacional da contribuiçâo previdenciária e demonstra-se que a fixaçâo do limite de imunidade em valor absoluto, sem levar em conta as bases de cálculo sobre as quais incidiram as respectivas contribuiçöes, ofende o principio da igualdade tributária.
This paper is a short review of Mamoon (2007) analysis on inequality where it is contrasted with growth. The economic processes or institutional dynamics that are good for growth may not be a ...priority if inequalities are the prime consideration. For example rule of law and control for corruption are the most salient factors to mitigate inequality but though they are also good for growth, it is good regulation that takes the lead in growth promotion. China has been benefitting from good market regulation - a pro capitalist economic tool kit while suffering from rising inequality that may be due to less emphasis on control for corruption.
This paper reviews recent research on the relationship between central bank policies and inequality. A new paradigm which integrates sticky‐prices, incomplete markets, and heterogeneity among ...households is emerging, which allows for the joint study of how inequality shapes macroeconomic aggregates and how macroeconomic shocks and policies affect inequality. The new paradigm features multiple distributional channels of monetary policy. Most empirical studies, however, analyze each potential channel of redistribution in isolation. Our review suggests that empirical research on the effects of conventional monetary policy on income and wealth inequality yields mixed findings, although there seems to be a consensus that higher inflation, at least above some threshold, increases inequality. In contrast to common wisdom, conclusions concerning the impact of unconventional monetary policies on inequality are also not clear cut. To better understand policy effects on inequality, future research should focus on the estimation of General Equilibrium models with heterogeneous agents.
