The growth–inequality association: Government ideology matters

This note suggests that the association between income inequality and economic growth rates might arguably depend on the political ideology of incumbent governments. Estimates indicate that under leftwing governments, inequality is negatively associated with growth while the association is positive under rightwing governments. This may provide a qualification to recent studies of inequality.     

Unfair inequality and growth*

Fighting against economic inequality is one fundamental social goal in the agendas of most governments. However, recent studies highlight that people actually prefer unequal societies, as they accept inequality generated by an individual's effort and wish to reduce only unfair inequality (generated by factors beyond an individual's control). This distinction might help to explain the fundamental unsolved question about whether inequality is good or bad for growth: unfair inequality (UI) could be growth-deterring, while fair inequality (FI) might be growth-enhancing. We derive a reduced-form growth equation from a stylized overlapping-generations model with human capital that includes FI, UI, and poverty. Then, using an instrumental variable approach, we show for alternative samples and inequality measures at the worldwide level that the estimated coefficient associated with UI is always negative, while the coefficient of total inequality increases when UI is included in the regression. Moreover, we find that poverty mediates this relationship because the higher the poverty rate, the smaller the impact of either type of inequality on growth.     

A political foundation of public investment and welfare spending

This paper develops a political economy model to examine the implications of political selection under an authoritarian regime. We formalize the fiscal policy choice of local governments, focusing on two political selection mechanisms and their implications for public investment and welfare spending. A growth-oriented promotion system induces local officials to increase public investment, which may increase output but crowd out welfare transfers. This mimics the recent investment-driven growth in China and relatively low effort to tackle high inequality. Under a broader incentive structure, we show that it is possible for an authoritarian regime to attain the social welfare of a democracy.     

GROWTH,INEQUALITY, AND ECONOMIC FREEDOM: EVIDENCE FROM THE U.S. STATES

This article returns to the discussion of how income inequality affects economic growth. The main argument of the article is that economic freedom is likely to mediate the association between inequality and growth. In a panel of 300 observations from six 5‐year periods across the 50 U.S. states, I employ five different measures of inequality. The results show that across measures, the growth effects of inequality turn more positive with more economic freedom. The moderating effects are mainly driven by measures of public sector consumption. (JEL O11, O38, O43, P48)     

LOCAL DISTRIBUTIONAL EFFECTS OF GOVERNMENT CASH TRANSFERS IN CHILE

Despite rapid economic growth and poverty reduction, inequality in Chile has remained high and remarkably constant over the last 20 years, prompting academic and public interest in the subject. Due to data limitations, however, research on inequality in Chile has concentrated on the national and regional levels. The impact of cash subsidies to poor households on local inequality is thus not well understood. Using poverty‐mapping methods to asses this impact, we find heterogeneity in the effectiveness of regional and municipal governments in reducing inequality via poverty‐reduction transfers, suggesting that alternative targeting regimes may complement current practice in aiding the poor.     

Foreign direct investment,growth and income inequality in less developed countries

How does foreign direct investment (FDI) affect economic growth in less developed countries (LDCs)? What is its association with changes in the income distribution? This paper empirically examines these issues within a cross section of less developed countries between 1970 and 1989. FDI is positively associated with economic growth within this sample of countries. However, there is no strong association between FDI and changes in income inequality within these same countries and over this same time period. Hence, there is no evidence that FDI is increasing income inequality within this group of LDCs.     

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.     

Income Inequality is not Harmful for Growth: Theory and Evidence

The paper shows that income inequality may theoretically lead to higher economic growth if public consumption enters the utility function. Empirically, baseline estimations and a sensitivity analysis show that income inequality is positively, and most of the time significantly, associated with economic growth. These findings stand in sharp contrast to the negative association between inequality and growth propounded by Alesina and Rodrik and by Persson and Tabellini.     

The impact of redistributive policies on inequality in OECD countries

Due to behavioural effects triggered by redistributional interventions, it is still an open question whether government policies are able to effectively reduce income inequality. We contribute to this research question by using different country-level data sources to study inequality trends in OECD countries since 1980. We first investigate the development of inequality over time before analysing the question of whether governments can effectively reduce inequality. Different identification strategies, using fixed effects and instrumental variables models, provide some evidence that governments are capable of reducing income inequality despite countervailing behavioural responses. The effect is stronger for social expenditure policies than for progressive taxation.     

经济分权、人口迁徙与大国发展之路——基于人均产出增长地区差异的实证分析

文章从分权式改革的视角分析了中国改革开放30年来的经济发展道路,总结了中国经济高速增长的主要成功经验在于政治集权下的经济分权。但是经济分权并不能有效缩小城乡、地区与贫富差距,其原因在于中国人口不能自由迁徙,对落后地区的地方政府不能实现"用脚投票"效应,从而影响了对地方政府的监督与激励作用。文章指出只有在人口自由迁徙的条件下,政治集权下的经济分权才能有效激励地方政府,特别是落后地区地方政府发展地方经济的积极性。在认清分权式改革与人口迁徙关系的基础上,正确设计下一步的改革方略,有利于中国真正走出一条大国发展之路。     

Inequality aversion in post-communist countries in the years of the crisis

This article provides estimates for the parameters of inequality aversion for 10 post-communist economies of central and eastern Europe in the years of the crisis. To this aim, we employ the information on the level of tax progressivity available in the European Union Survey on Income and Living Conditions cross-sectional microdata, under the assumption that the principle of equal sacrifice drives the choices of governments on marginal tax rates. Results reveal a remarkable variety of preferences for redistribution across the countries during the time period considered (2008–2012), with some of them converging towards the generally higher inequality aversion levels of the western European Union, perhaps as a result of policy responses to the crisis.     

The political economy of income comparisons and economic growth

The literature on income inequality has provided various explanations as to how income inequality can affect growth, with the emphasis on ideas such as investments in human capital, issues of occupational choice, or the redistributive policies of governments. Inequality not only has a direct effect on the distribution of consumption in an economy, but it also has a powerful effect on people's subjective sense of well being. This paper takes a novel approach by focusing on the way in which a government's choice of economic policy can be influenced by how individuals perceive themselves relative to other individuals, both within the country and in foreign countries. The chosen policy affects economic growth, with the assumption being that policies that promote growth also tend to result in more switching of individuals between income groups. We show that the government's optimal policy depends on the importance of both inside country and outside country income comparisons, the fraction of national income earned by the different income groups, the potential magnitude of economic growth, the probability of switching between income groups in the presence of growth, and the relative importance of the various income groups. The model predicts that a greater degree of inside country income comparison is bad for growth whereas more outside country comparison is good for growth.     

Causal relationship between apparel exports and macroeconomic factors

Apparel exports make a significant contribution to economic growth in major apparel exporting economies such as Bangladesh, Sri Lanka and Vietnam. This study aims to investigate the causal relationship between apparel export growth and its determinants such as GDP growth, infrastructure, financial development, foreign direct investment (FDI) and labour productivity using panel data from 11 major apparel exporting countries for the period 1996 to 2013. The results confirm a long-run equilibrium association among the variables and reveal that GDP growth, infrastructure, financial development, FDI, and labour productivity have a significant positive influence on apparel export growth. Furthermore, the heterogeneous panel non-causality test results suggest that GDP growth, infrastructure and labour productivity contribute to apparel export growth in the short-run. These findings have several policy implications for the governments of the countries under study.     

EARNINGS INEQUALITY, LABOUR SUPPLY AND SCHOOLING IN HUSBAND–WIFE FAMILIES

This paper describes the association between market work and earnings inequality across families over the life cycle and over calendar time with special attention to the different experiences of college‐educated and high‐school‐educated people. A concise and effective accounting framework is developed that allows for an assessment of the effect of the growing market employment of married women on family earnings inequality. Applying this framework to pseudo‐panel data from successive Current Population Surveys indicates that the increase in wives' employment has diminished the growth in family earnings inequality especially for well‐educated couples. Inferences about the level and change in earnings inequality depend on the degree of labor market attachment of the people studied especially in the case of wives.     

收入不平等与经济增长：移动的库兹涅茨曲线*——新时期收入分配改革的思路与意义

准确判断收入不平等对经济增长的影响，对于客观评价中国各个阶段的收入分配制度改革尤为重要。本文在统一增长理论的框架下引入收入不平等因素，构建了一个人口数量、不平等和经济增长同时内生的理论模型，并利用CGSS数据构造收入不平等指标，使用中国省际非平衡面板数据进行经验检验。研究发现：收入不平等与经济增长之间呈现倒U型关系。更重要的是，随着经济发展水平的提高，倒U型曲线将逐渐向左移动，即最优的收入不平等程度随着经济发展水平的提高而逐渐降低。这一发现意味着改革开放以来，中国各个时期的收入分配制度改革均是在特定历史条件下的最优选择。本文的结论具有深刻的政策含义：为了提高经济增长率，需要进一步巩固“脱贫攻坚”成果，逐渐加大收入分配调节力度，使收入分配制度改革紧跟经济发展的步伐，根据经济发展水平不断缩小收入不平等程度。     

ICT and income inequality: a cross-national perspective

The importance of information and communications technology (ICT) for economic growth and development is widely researched and seemingly well understood, but the effect of such investments on income inequality is less well documented. On the one hand, improvements in infrastructure are expected to expand economic opportunities for previously underserved populations. On the other hand, ICT growth may exacerbate inequality due to differential access and skill premiums. We use panel data from 109 countries during the period 2001–2014 to examine the empirical connection between ICT and income inequality in a cross-national context. Our results suggest that the effect of ICT on income inequality depends both on the specific type of ICT and on the measure of income inequality. In addition, the magnitude of ICT’s effect on income inequality is comparable to that of more traditional forms of economic infrastructure. Finally, we find that the association between ICT and income inequality is conditional on other economic and political characteristics.     

Redistribution,trade and corruption: an empirical assessment

ABSTRACT

This article explores the role of institutional quality in the trade and inequality nexus. Does corruption shape the relationship between trade and inequality through its impact on redistribution? Our answer to this question builds on the hypothesis that trade raises inequality and that governments may want to intervene through appropriate redistribution schemes that aim at taxing the gains from trade in a way that offsets the negative effects of trade on inequality. Moreover, we argue that this mechanism may be distorted by corruption and bad institutions in general. Quite to the contrary to common wisdom, we find that trade reduces inequality in countries with high institutional standards by means of a low level of corruption but increases inequality in countries with low levels of institutional quality.     

Credit constraints,inequality and the growth gains from trade

This paper tests the hypothesis that, in the presence of credit constraints, higher wealth inequality affects negatively the growth gains from trade liberalisation. Variations in the growth rate of value added–decomposed in the growth rate of the number of establishments and the growth rate in average size–of manufacturing industries in 34 developing countries before and after trade liberalisation are used to study the effects of inequality on the difference in growth under liberalised and nonliberalised regimes. The results show that the number of firms in industries with high dependence on external finance in countries with higher inequality grow significantly slower, in both statistical and economic terms, than in industries with low dependence on external finance in countries with lower inequality following a trade liberalisation relative to the closed-economy period.
