Inequality and income: The mediating effects of social spending and risk

This paper estimates models of social spending, income risk, and per capita income levels using data from a post-war panel of OECD (Organisation for Economic Cooperation and Development) countries. The objective is to test two theories about the pathway from inequality to per capita income. According to one theory, inequality reduces incomes because it induces social spending, which acts as a drag on the economy. The results here suggest, however, that inequality does not seem to induce social spending, and social spending does not seem to lower per capita incomes. According to a second theory, inequality causes upheaval which adds to the volatility of per capita income, which may reduce the level of per capita income. The results suggest, however, that volatility, measured here as the standard deviation of per capita income, has little measurable impact on either per capita income or social spending. The mainsprings of per capita income are more likely to be the traditional factors: the work force, human capital, and physical capital.

Labour Productivity: A Comparative Analysis of the European Union and United States, 1994–2007

This article confirms that labour productivity in the European economies has continued to slow down in recent years. U.S. productivity growth has been higher than in the EU, but only since 2001. At the same time, both economies have modified previous employment performance: EU employment growth is now higher than in U.S. This article proposes that productivity growth be explained by demand dynamics, and investment in particular, not forgetting the influence of employment, along with other factors such as new technologies.     

基于经济指标构建的社会稳定风险评估研究

本文选用人均GDP、 GDP增速、基尼系数、物价指数和失业率等5项经济指标对社会稳定风险进行了评估,结果表明：国际横向比较,我国社会稳定程度目前处于中等偏上水平,主要得分在高速的GDP增长、较低的物价指数和失业率方面;自身纵向比较,我国社会稳定风险近年呈加大趋势,主要失分在贫富差距扩大和通货膨胀压力上升方面。笔者的分析结果显示,确保在贫富分化项上不再失分甚至有所加分,即确保贫富差距不再扩大并力争有所缩小,对于保持社会稳定极其重要。     

(How) do flexible labour markets really work? The role of profitability in influencing unemployment

This paper assesses the theoretical justifications availablefor policies of flexible labour markets (FLMs) in reducing thelevel of unemployment in developed economies. It empiricallyassesses the OECD's rationalisation of policy linking profitabilityto investment and job creation in four country cases. New capitalinvestment is found to be significant for unemployment in allcases but it is not found to be a consequence of the mechanisticachievement of ‘normal’ profits. Without an empiricallysupported mechanism for how FLMs reduce unemployment, the policyis open to the accusation of being no more than a politicaltool for altering distribution, without concern for the widersocio-economic consequences.     

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。     

Can social spending cushion the inequality effect of globalization?

This paper examines whether social spending cushions the effect of globalization on within‐country inequality. Using information on disposable and market income inequality and data on overall social spending, and health and education spending from the ILO and the World Bank/WHO, we analyze whether social spending moderates the association between economic globalization and inequality. The results confirm that economic globalization—especially economic flows—associates with higher income inequality, an effect driven by non‐OECD countries. Health spending is strongly associated with lower inequality, but we find no robust evidence that any kind of social spending negatively moderates the association between economic globalization and inequality.     

The Future Be Damned: Economists’ Optimism and Nuclear Proliferation

Lower income households make much heavier use of costly financial services, such as payday loans, check cashing services, auto title loans, and many more. These services are crafted for, targeted to, and distributed through outlets in lower income neighborhoods. In other words, there are extensive provisioning systems designed specifically to deliver such products and services to these households. Such marketing aimed at lower income groups reduces both their wealth and welfare relative to upper and upper middle groups.     

Mass Society and Political Conflict: Toward a Reconstruction of Theory

Many recent studies in economics have uncovered the economic and socio-economic factors that are most related to differences among nations in citizens' self-reported levels of well-being (SWB). However, these cross-country studies have generally not taken into account the fact that around the SWB national average, a considerable spread of scores exists within nations. In an extreme case, a country may be in the midst of a major social upheaval, with a large group of dispossessed and disadvantaged individuals, yet this fact is completely hidden by the arithmetical average. Using cross-country data with diverse economic and socio-economic characteristics and the latest available dataset on well-being, we uncover the factors that appear to be the most highly correlated with the inequality of well-being within nations. We find the inequalities in individual incomes and quality of health, and the level of institutional qualities to be most important in explaining the inequalities of well-being.     

中国经济增长与收入差距关系的经验研究

经济增长与收入差距的关系是一个古老而又充满活力的问题。研究发现,尽管全国总量时序数据的Granger因果关系检验表明,中国的经济增长与收入差距不存在任何方向的因果关系,但以各省GDP增长率和城乡收入比为观测点的面板数据检验结果显示:不论是在短期还是在长期,收入差距的扩大都是引起经济增长的Granger原因;经济增长在短期会引起收入差距的扩大,但从长期看,有助于收入差距的缩小。     

Does economic freedom increase income inequality? Evidence from the EU countries

This paper examines the relationship between economic liberalization and income inequality in the EU using panel data for the 2000s. The empirical evidence suggests that economic freedom is strongly related to income inequality. However, not all areas of economic freedom affect income distribution similarly. Government size is robustly associated with inequality, and also when controlling for potential endogeneity in a dynamic panel data analysis. Regulation is linked to income inequality as well, whereas legal system and sound money have no significant effects on income distribution. In the case of freedom to trade internationally, the relationship differs between old (EU-15) and new (former socialist) EU countries.     

收入不平等对经济增长影响的实证研究

采用联立方程分析方法,实证分析了收入不平等对经济增长影响的三种机制,探讨了收入不平等如何通过影响物质资本投资、人力资本投资和居民消费来作用于经济增长。结果表明,从长期看收入不平等的扩大会刺激物质资本投资,但不利于人力资本投资和居民消费增长,收入不平等对经济增长的长期影响为负。因此,从经济发展的角度政府不应容忍收入不平等的过分扩大。     

How does informal employment impact income inequality?

This study investigates how informal employment impacts total income inequality in urban China. Finite mixture methodology is employed to examine the segments that exist in the informal labour market, and the Theil index (T0) is used to break down total income inequality according to different subsamples. We found that the two-segment model (upper-tier and lower-tier) best describes the structure of the informal labour market in urban China and that the upper-tier segment contributes most to the total income inequality.     

收入不平等对中国经济增长的影响

使用21个省市的面板数据,对收入分配总体不平等进行分解,实证检验农村不平等、城市不平等以及城乡间不平等对经济增长的影响。研究发现:农村不平等程度越高,对经济增长的抑制作用越大;城市不平等对经济增长没有显著的影响;城乡间不平等与经济增长之间存在负相关关系。农村不平等、城乡间不平等与城市不平等相比,前两者在解释人均产出增长时发挥了更重要的作用。
