Economic,structural and socio‐psychological determinants of protests in Russia during 2011–2012

This empirical analysis is based on the latent variable framework to identify key determinants of protests in Russia during 2011–2012. We derive logistic regressions from the revolution constraints based on economic (the political Kuznets Curve) and socio‐psychological (grievance) theories of protest. Our findings suggest a positive linear relationship between income and income inequality, contradicting the Kuznets curve. Our estimations show that inequality, share of the poor, the relation of the governor's family income to the average family income, distance to Moscow and accumulated human capital increase the risk of protest, whereas transfers and subsidies decrease these risks.     

Financial deepening and income inequality: Is there any financial Kuznets curve in China? The political economy analysis

The interconnectedness of financial deepening and income inequality has been a highly controversial discussion which has not been concluded despite many empirical and theoretical studies up to date. One of the basic building blocks for many research designs is the reliance upon the Kuznets inverted U-shaped curve which postulates that in the first phase of economic growth income inequality increases, peaks and then decreases to a tolerable level in the later phase after a certain income level had been attained. The role of financial deepening in financing economic growth is an indispensable and necessary condition enabling us to easily draw an analogy between financial deepening and income inequality in a financial version of the Kuznets curve. In spite of 30 years of economic and financial reforms in China, which represents a fairly young history of economic growth and development, there are many indicators that Chinese experience significantly deviates from the presupposed inverted U-shaped curve trajectory and its final equalizing effect. This paper relies on financial deepening data measured by monetary aggregate M2/GDP and domestic banking credit/GDP ratios in its claim that they significantly correlate with rising income inequality. The author’s intention consists not in claiming that financial deepening per se causes income inequality, but provides a political economy analysis of the specific institutional and power configuration which leads to their positive relationship. This configuration is determined by the prevailing banking model, the hukou system, financial repression and the decentralized authoritarian system. On the other hand, the absence of inequality-narrowing institutitons further aggravate the problem. All the aforementioned factors are geared at avoiding mechanical and spurious claims that financial deepening increases or decreases income inequality across countries. A historical institutionalism approach to explain China’s path related to the Kuznets curve prediction shows the central validity of open and inclusive institutions in generating inequality-narrowing benefits of financial deepening.     

Education and Income Inequality: New Evidence From Cross-Country Data

This paper presents empirical evidence on how education is related to income distribution in a panel data set covering a broad range of countries for the period between 1960 and 1990. The findings indicate that educational factors—higher educational attainment and more equal distribution of education —play a significant role in making income distribution more equal. The results also confirm the Kuznets inverted–U curve for the relationship between income level and income inequality. We also find that government social expenditure contributes to more equal distribution of income. However, a significant proportion of cross–country variation in income inequality remains unexplained.     

Does S. Kuznets's belief question the Environmental Kuznets Curves?

Abstract.  This paper examines the link between pollution and income. The main purpose is to assess whether the introduction of income inequality in a Environmental Kuznets Curve (EKC) analysis can give new insights into the relationship between pollution and economic growth. The EKC hypothesis proposes that there is an inverted U‐shape relation between environmental degradation and income per capita. We question this common result, in a simple model where the income inequality evolution is exogenous and where the planner could use only one instrument. For a set of parameter values we find, for example, a two‐hump curve. JEL classification: D3, H4, Q2.

Carbon dioxide emission and income: A temporal analysis of cross-country distributional patterns

This paper explores the relationship between the inter-country income inequality and CO₂ emission and temporal shifts in such a relationship. It also examines how the mean per capita CO₂ emission and its distributional inequality are related to the corresponding mean and the distributional inequality of income. The analysis is based on a cross-country panel data set at the level of country-group. Here environmental damage is treated as a private good and the technique of Lorenz and specific concentration curve analysis have been used as the basic analytical framework to argue that distributional inequality of income should be an explanatory variable in the Environmental Kuznets Curve relationship, along with the mean income level. In the empirical exercise, Johansen's cointegration analysis technique is used to explore existence of statistically significant cointegrating vector(s) relating mean emission and Specific Concentration Ratio of emission to mean income level and Lorenz Ratio of income, using a set of country-group specific time series data set which covers four country-groups (viz., Africa, America, Asia and Europe) and the World as a whole. The empirical results confirm that the inter-country income inequality has significant effect on the mean emission level and inter-country inequality of emission level for most of the country-groups considered.     

Distributional Consequences of Competitive Structural Change

This paper examines the distributional consequences of a shift toward a more capital intensive technique in an economy inhabited by infinitely-lived consumers and with a complete set of competitive markets. We show that income inequality goes through a form of Kuznets curve: inequality jumps when the capital intensive technique is introduced, monotically rises during the structural change, and abruptly falls when the adoption of the new technique ends. The total effect of the structural change is an increase in income inequality.     

Inequality and Economic Growth: A Global View Based on Measures of Pay

This paper discusses two issues in the relationship betweeninequality and economic growth: the data and the econometrics.We first review the income inequality data set of Deiningerand Squire (D&S), which, we argue, fails to provide eitheradequate or accurate coverage, whether through time or acrosscountries. We then introduce our own measures of the inequalityof manufacturing pay, based on UNIDO's Industrial Statistics.These provide indicators of pay inequality that are more stable,more reliable and in our view also more comparable across countries,than the D&S data. Turning to the fabled "Kuznets" relationship between inequalityand economic development, we diagnose several common econometricproblems in the literature, including measurement error andomitted variable bias. By taking steps to account for theseproblems, and by introducing a more complete panel data setbased on pay inequalities, we seek more reliable inferencesconcerning the relationship between inequality, national incomeand economic growth. We find evidence that generally supportsKuznets' specification for industrializing countries: pay inequalitytends to decline as per capita income increases, though withsome tendency for the relationship to curve up for the richestcountries. After 1981 two findings emerge. First, per capitaGDP growth slowed dramatically in most countries, increasinginequality along the augmented Kuznets curve. Second, thereis a global and macroeconomic effect that produces rising inequalityin our data, independent of GDP or its changes. The timing ofthis effect suggests a link to the high real interest ratesand global debt crisis of the period beginning in 1982. (JELC23, D31, J31, O11)     

The income inequality curve in the last 100 years: What happened to the Inverted-U?

This paper examines the shape of the curve that represents the long-run relationship between income inequality and economic growth, using data from four developed countries (USA, UK, France, and Germany) over the period 1915 – 2014. The analysis is carried using a panel data technique (fixed, random, and interactive effects) that takes into account common shocks. We find that in the long-term, this curve has the shape of an “N-shape” and that the Kuznets curve does not explain this path. We also present many factors that may affect the path of inequality up or down, the most important is political, economic and demographic, specifically technological change, globalization, social transfers, economic policies, trade unions, taxation, education, war, and epidemics.     

Taking down the wall: Transition and inequality

In this article, we investigate the main determinants of income inequality in the transition countries of Central and Eastern Europe and the Commonwealth of Independent States during the period 1990–2018. To this end, we address a major methodological challenge that lies at the core of the cross‐country literature on income inequality: the potential endogeneity of income per capita, which is largely ignored by most empirical studies. We adopt a two‐pronged empirical strategy by (1) using trading partners’ weighted average real GDP as an instrumental variable and (2) estimating the model via the two‐stage least squares approach for static models and the generalized method of moments estimator for dynamic models. Our empirical findings are consistent with the Kuznets curve that illustrates a nonlinear relationship between income inequality and the level of economic development. We also find that the redistributive impact of fiscal policy is statistically insignificant and taxation and government spending appear to have the opposing effects on income inequality in transition economies over the sample period.     

Education stock and its implication for income inequality: The case of Asian economies

This study develops a quadratic relationship between education and income inequality among Asian developing economies for the period from 1960 to 2015. Panel cointegration and fully modified OLS is applied for the estimation of long‐run coefficients. The results show that initial, primary, secondary, and tertiary enrollment increases inequality. However, the effect of education on income inequality becomes negative after a certain threshold level (i.e., 97.5% for primary, 43.5% for secondary, and 11% for tertiary). Thus, this result proves the Kuznets phenomenon of an inverted U‐shape relationship for primary, secondary, and tertiary enrollments.     

An Exploration of the Conceptual and Empirical Basis of the Environmental Kuznets Curve

We examine the conceptual and empirical basis of the environmental Kuznets curve. From both perspectives, the relationship lacks firm foundations. In particular, the empirical relationship is shown to be highly sensitive to the choice of pollutant, sample of countries and time period. This strongly suggests that there is an omitted variables problem. We find that two important omitted variables are education and inequality. Also, we show that the observed relationship is sensitive to the measure of income/welfare used. The paper concludes with a discussion of some policy implications of our findings.

Inequality,Democracy, and Persistence: Is There a Political Kuznets Curve?

The aim of this paper is to provide comprehensive empirical evidence on recent theories that link democracy and income inequality for the period 1960–1997. In simple cross-country regressions I find a non-monotonic link between democracy and inequality when using ordinary least squares, instrumental variables, and Eusufzai tests. I also employ dynamic panel data techniques, which control for potential simultaneity and heterogeneity problems. I also find support for the existence of apolitical Kuznets curve. Moreover, it appears that income inequality is unconditionally persistent. Results are robust to different democracy proxies when sensitivity analysis is applied.     

库兹涅茨假说可以解释中国的收入差距变化吗

本文利用中国的数据对经济增长与收入分配的关系进行了经验分析。分析结果没有对库茨涅兹的"倒U型假说"给予足够的支持。中国农村内部、城镇内部和城乡之间的收入差距及其变化特点有其自身的特点,需要从经济发展因素、经济体制转型的因素和政策因素上加以解释。

Entrepreneurship and income inequality: a spatial panel data analysis

The main objective of this paper is to empirically analyze the relationship between entrepreneurship and income inequality. We use a spatial panel data analysis for both 33 high-income countries and 39 middle- and low-income countries over a period of 11 years. Estimation results and rigorous diagnostic analysis suggest that: (i) there is a strong support for the existence of an inverted U-shaped relationship between entrepreneurship and income inequality espoused by the Kuznets Curve hypothesis; (ii) the relationship between entrepreneurship and income inequality is negatively moderated by country’s level of economic development; (iii) regardless of income inequality levels, entrepreneurship has a non-linear relationship with income per capita; (iv) gross domestic expenditure on research and development exhibits significant negative impacts on entrepreneurship; (v) significant mixed effects on the likelihood of entrepreneurial activity are observed with governance, globalization, population growth rate, and competitiveness variables; (vi) there are significant mixed feedback effects on entrepreneurship; and (vii) there are statistically significant, positive as well as negative spatial spillovers to country-level entrepreneurial activity.     

Measuring the Impact of Various Income Sources on the Link between Inequality and Development: Implications for the Kuznets Curve

To understand the link between inequality and development, a decomposition of the Gini index by income sources is used that emphasizes the role of three components measuring the impact of the shares of the sources, the degree to which they are unequally distributed, and their correlation with total income. Such a breakdown explains why the rising section of the Kuznets curve is mainly the consequence of the increasing share of wages while its declining section reflects the decreasing share of entrepreneurial income and the negative correlation between transfers and total income. The data sources were provided by the International Labour Office.     

EFFECT OF INCOME DISTRIBUTION ON THE ENVIRONMENTAL KUZNETS CURVE

This paper augments the model of Andreoni and Levinson by analyzing the effect of income distribution on the inverted U‐shaped relationship between some forms of pollution and income, the so‐called ‘environmental Kuznets curve’. In a context in which pollution abatement technology shows increasing returns to scale and an inverse U‐shaped pollution–income path is present, this study demonstrates the existence of a majority voting equilibrium, and concludes that the inverted U‐shaped relationship is between median income and environmental degradation rather than between per capita income and environmental degradation. Our results suggest that an increase in equality in income distribution improves environmental quality and social efficiency. The implication of the model for the empirical estimation of environmental Kuznets curves is examined using a panel data set of 36 countries over a 20‐year period. Estimation results using different models show that income distribution might be an important factor in the empirical estimation of these curves.     

Poverty decompositions with counterfactual income and inequality dynamics

Traditional poverty accounting decomposes changes in a country's poverty headcount ratio into changes in income and inequality. We argue that this approach is unsatisfactory from the perspective of policy analysis because it compares a country in two points of time without taking the country's initial situation, and hence its potential for poverty reduction, into account. We thus suggest comparing traditional poverty decompositions with a counterfactual situation. This counterfactual indicates what a country starting from its initial situation could be expected to achieve in terms of income, inequality, and, hence, poverty developments. We construct those counterfactuals by modeling income and inequality trends characterized by convergence and a “Kuznets” relationship between inequality and development. Parameters in those relationships are estimated using PovcalNet survey data from 144 countries and we construct our counterfactual poverty predictions for 71 developing countries. While there is overall a tight relationship between actual developments and counterfactuals, we identify several cases, where both deviate from each other and discuss the policy implications. We also check for commonalities in differently performing countries and find that those who fell particularly short of expectations often underwent political transition and state fragility.     

Decentralisation and income inequality in Central and Eastern European countries

This paper provides empirical evidence for the association between fiscal decentralisation and income distribution for a panel of 11 economies from Central and Eastern Europe (CEE) during 1992–2016. We focus on three research topics: the effect of decentralisation on income inequality; the effects of the structure of subnational government finance on income inequality; and the validity of the Kuznets hypothesis. The main findings from the empirical exercise are as follows: first, we provide firm evidence on the presumed favourable effects of fiscal decentralisation on income distribution in the CEE countries; second, our empirical model suggests that the effects of fiscal decentralisation on income inequality are dependent on the source of finance of subnational governments, i.e. intergovernmental transfers may have a role in income equalisation; third, we cannot confirm the validity of the Kuznets hypothesis in CEE countries.
