Income Distribution,Household Debt and Growth in Modern Financialized Economies

Abstract:

We analyze some core features of the institutional transformation of the Canadian and U.S. economies over the last half century, as they became increasingly financialized economies resting on household consumption as the key contributor to economic growth, despite weak growth in real wages and personal disposable income. This growth in consumption spending is highly fragile not only because it is a debt-led growth that has relied on an unsustainable expansion of household indebtedness largely dependent on credit bubbles in the housing market, but also because of the perverse form of this indebtedness. Studied from the angle of disaggregated household consumption/saving behavior, it is the poorest and most vulnerable households who have been building up unsustainable debt, thereby presaging increasing financial fragility and crises.     

Household Income Inequality and Income Mobility: Implications Towards Equalizing Longer-Term Incomes in India

This paper addresses three important questions. First, what are the trends, levels and sources of income inequality in India? Second, how have been the patterns of income mobility? And finally, exploring the relationship between income mobility and income inequality in the context of India. Results, based on recent India Human Development Survey (IHDS) longitudinal data, advocate that not only is income inequality very high, nonetheless, it has increased – mainly attributable to different income sources – in India. The paper also focused on whether or not this income mobility equalizes longer-term incomes. Results suggest income mobility has resulted in-albeit not robust- equalizing longer-term incomes. Thus, based on imperative findings, the paper suggests, the nature of longer-term well-being is crucial to designing policy interventions to effectively tackle inequality and in this context, economic mobility can be seen as an avenue to long-term equality.     

Debt Overhang and Deleveraging in the US Household Sector: Gauging the Impact on Consumption

Using a novel data set for the U.S. states, this paper examines whether household debt and the protracted debt deleveraging help explain the dismal performance of U.S. consumption since 2007 in the aftermath of the housing bubble. By separating the concepts of deleveraging and debt overhang—a flow and a stock effect—we find that excessive indebtedness exerted a meaningful drag on consumption over and beyond wealth and income effects. The overall effect, however, is modest—‐around one sixth of the slowdown in consumption between 2000–06 and 2007–12—and mostly driven by states with particularly large imbalances in their household sector. This might be indicative of non‐linearities, whereby indebtedness begins to bite only when misalignments from sustainable debt dynamics become excessive.     

Inequality and Crisis: Conspicuous Consumption as the Missing Link in the Portuguese Case

Portuguese household debt increased above GDP between 2000 and 2007. This article uses conspicuous consumption to explain credit demand dynamics. The author develops an institutionalist framework and consider how rapid high inequalities and increasing top income share favored conspicuous consumption and climbing household debt.     

Market Demand Elasticity and Income Inequality

This paper deals with the analysis of the relation between aggregate demand for a consumption good and the distribution of income across consumers. We obtain sufficient conditions under which changes in income inequality lead to an increase or decrease in the market demand elasticities. The conditions are satisfied for individual demand functions commonly used in economic models, in particular, for the typical demand functions on luxury goods and necessities. An earlier version of this paper was titled “Market demand elasticity, equilibrium stability and income inequality”.

中国城镇、农村居民消费的分析与比较

在借鉴西方跨期最优消费选择理论和相对收入假说所提出的"棘轮效应"的基础上,估计中国的消费函数,鉴于我国城镇和农村居民在消费行为方面存在差异,本文分城镇居民和农村居民对模型单独进行检验,考察两者在影响消费的因素方面的差异,并试图找到产生这种差异的原因。最后,根据城镇居民和农村居民消费函数的不同特点,提出拉动居民消费的政策建议。     

中国居民收入差距对消费倾向变动趋势的影响

本文以消费的边际效用递减规律为基础,探讨了居民收入差距和消费倾向间可能的关系,并对中国居民消费倾向变动趋势进行解释.本文分析表明,收入差距对消费倾向可能的影响和经济发展水平有关系,当经济发展到一定程度时,居民收入差距在一定的范围内变化不会影响消费倾向的变化,但超过一定范围后,随着收入差距变大,消费倾向变低.我们认为过大的居民收入差距是造成近年来消费倾向变低的重要原因.     

中国家庭债务和资产积累关系的实证分析:1997-2008

笔者运用1997年～2008年中国家庭债务和家庭资产积累的时间序列数据,定量分析了家庭负债和家庭资产积累的关系。研究发现,家庭债务和家庭资产积累存在同向的长期均衡关系,家庭债务的变动会影响家庭资产的积累。笔者提出促进家庭资产合理配置和防范中国家庭债务快速增长带来的消极后果的相关建议,旨在为决策部门制定合理的经济政策提供参考。     

收入不平等对人口健康影响的研究综述

自1970年代以来,西方学者从理论假设和实证研究两个角度对收入不平等对于人口健康产生的影响进行了深入而广泛的研究,采用跨国数据进行的研究基本上证实了收入不平等对于人口健康产生的不利影响,而采用跨地区数据以及个人数据进行的研究得出的结论则不尽一致.本文主要从理论假设、实证研究和影响途径三个角度对收入不平等对于人口健康的相关研究进行梳理和归纳,以期对我国的相关研究有所启示.     

西部地区农户收入水平对农村能源消费的影响分析

西部地区农村人口众多,农村能源建设是西部地区可持续发展的一个重要条件,而沼气建设是西部农村能源建设的重点。文章在介绍西部地区农村能源概况的基础上,对农户收入水平对沼气消费的影响进行理论、实证分析,得出农户人均纯收入水平对农村人均沼气消费量的影响是非线性关系的结论,提出针对不同收入水平的农户采取相应的措施来解决农村能源短缺,促进生态农业良性发展。     

收入分配不平等、有效需求与经济增长——一个基于中国经济转型期的实证研究

本文从有效需求角度入手,探究中国经济转型期经济增长与收入分配不平等之间的关系,并运用中国1978-2005年间28个省市的面板数据,通过面板数据单位根检验、协整检验与误差修正模型,对中国经济增长与收入分配不平等、有效需求、劳动力、投资、教育以及收入分配不平等和有效需求交互影响之间的长期关系和短期关系进行了研究。结果显示,中国经济转型期经济增长与收入分配不平等、有效需求具有长期的均衡关系,收入分配不平等通过有效需求机制阻碍了经济增长,且在短期内效果也非常显著。     

The Effect of Better Information on Income Inequality

We consider an OLG economy with endogenous investment in human capital. Heterogeneity in individual human capital levels is modelled by a distribution of innate ability across agents. This distribution is common knowledge but, at young age, no agent knows his/her ability. The production of human capital depends on each individual’s investment in education. This investment decision is taken only after observing a signal which is correlated to his/her true ability, and which is used for updating beliefs. Thus, a better information system affects the distribution of human capital in each generation. Assuming separable and identical preferences for all individuals, we derive the following results in equilibrium: (a) If the relative measure of risk aversion is less (more) than 1 then more information raises (reduces) income inequality. (b) When a risk sharing market is available better information results in higher inequality regardless of the measure risk aversion.

Tourism,Consumption and Inequality in Central America

Much research in international political economy (IPE) has been criticised for focussing on large and powerful actors in post-industrial countries, to the neglect of sites, processes and actors in the global South. This article offers a corrective to this bias in two ways: by locating the analysis in two rural Central American communities; and by exploring the social relations of consumption in these communities. In doing this, I challenge assumptions about rural places being excluded from global processes and explore the complexities and contradictions of how such communities are inserted into global circuits of production and consumption. Drawing on extensive qualitative research, the article explores the ways in which capitalist development through tourism has reconstituted the political economy of consumption in terms of habits, attitudes and behaviour in these two communities. Using the community and the household as sites of analysis, I explore the complex ways in which inequalities have been reconfigured through changing relations of consumption. Certain kinds of social hierarchies, in particular traditional gendered power relations within the household, have been challenged. However, other inequalities – such as class, ethnicity and nationality – have been reinforced by these processes.     

居民资产、财富效应与我国城镇居民消费

现代消费理论认为财富是影响居民消费的重要因素,并且各种财富形式对消费水平影响不同.对我国居民资产财富效应的实证研究表明,股票资产在长期对居民消费有负向影响.财富效应微弱,而房产财富对居民消费的正向效应比较明显,刺激消费作用较强.当前财富效应的产生与我国股市发展不稳定及房地产市场的发展特性相关,而个人可支配收入和储蓄仍是影响我国居民消费支出的主要因素.     

中央银行独立性、收入不平等与通货膨胀--来自中国的实证检验

本文就中国人民银行独立性、收入不平等对通货膨胀的影响机制进行了分析探讨.我们引入中央银行目标函数,对中央银行独立性、收入不平等与通货膨胀间的作用机制进行了模型推理分析.而后我们整合了转型国家中央银行独立性的测度方法,并用此方法对中国人民银行的独立性进行了详细测定.最后,通过计量分析检验了以下结论:收入不平等是引致通货膨胀的一个经验性因素;中央银行独立性越强,越能有效抑制收入不平等引起的通货膨胀.     

A Systemic Debt Payoff Policy

The average family in the US takes on debt to buy homes, to get education, and sometimes to even pay for normal daily expenditures. Outstanding debt generates a stream of rents to creditors and has become a significant burden on many households. A policy of household debt forgiveness could increase both economic equality and individual liberty. Under what conditions might such a policy be socially acceptable and what would be the implications of such a policy? For debt forgiveness to gain social acceptance the U.S. population would have to perceive the policy as fair and believe that such a program would treat all households equally. Furthermore, any such policy would be politically impossible if it stripped asset owners of money due or would not substantially lower household debt levels. This article explores some possible parameters that a politically feasible policy would contain, and it offers an estimate of policy costs.     

The response of household debt to income inequality shocks: a heterogeneous approach

This article explores the impact of changes in income inequality on household indebtedness using Pedroni's heterogeneous panel VAR. As a result, we find evidence in support of large cross-country heterogeneity in the responses of household leverage to income inequality shocks. We also find that such heterogeneity stems from differences in the strength of financial regulations and supervision.     

收入、收入不均与健康:城乡差异和职业地位的影响

本文使用来自中国9个省的微观面板数据,检验了居民自评健康与家庭人均收入和社区内收入不均之间的相关关系。考虑到中国城乡分割的二元经济社会特征,本文将农村样本和城镇样本分开处理;考虑到中国的社会分层结构,计量方程中引入了代表职业地位的变量及其与收入和收入不均的交互项。在实证结果的基础上,本文讨论了收入、收入不均与健康关系的作用机制。主要结论是:收入与健康的关系、收入不均与健康的关系都存在城乡差异和职业差异,这说明在收入、收入不均与健康的关系中,社会经济地位的影响十分重要。要解决健康不平等问题,关键在于加强对社会经济地位较低者,主要是农村居民和生活在城镇的农民的医疗保障,同时要设法改善农村的基础设施和社会资本,并逐步取消各种造成城乡分割的制度。     

经济刺激计划与农村消费启动——基于我国农村居民收入分解的实证分析

文章在对我国农村居民收入构成进行分解的基础上,利用协整等计量工具时影响我国农村居民消费的各种因素进行了量化分析,并由此对照我国政府为应对世界经济危机而出台的一揽子经济刺激计划,分析经济刺激计划中各项具体政策措施在促进农村消费方面的作用.实证分析和政策分析的结果表明:(1)当前对农村居民消费具有显著影响的因素主要是农村居民经营性收入、工资性收入及国家财政农村救济费支出;(2)已出台的经济刺激计划,既有消费价格补贴等短期措施,也有旨在提高农村居民收入、完善农村社会保障、优化农村消费环境的长期性政策,时于促进农村消费具有很强的针对性;(3)未来促进农村居民消费仍需继续着眼于各种长期性政策.国家在加大财政支农力度时,应注重提高农林水事业费以外的支农支出比重;(4)县域经济是启动农村消费的关键.未来的政策着力点可以考虑将启动农村消费与发展县域经济、推动城乡一体化发展相结合.     

Accounting for United States Household Income Inequality Trends: The Changing Importance of Household Structure and Male and Female Labor Earnings Inequality

Using a shift‐share analysis on March CPS data, this paper estimates the degree to which changes in labor earnings, employment, and marriage patterns account for household income inequality growth in the United States since 1979. The factors contributing to the rapid rise in income inequality in the 1980s differ substantially from those contributing to its slower increase since that time. Unlike findings for the 1980s when changes in the correlation of spouses' earnings accounted for income inequality growth, this factor is no longer a major contributor toward its continued increase. Additionally, the 2000s business cycle is the first full business cycle in at least 30 years where changes in earnings of male household heads accounted for declines in income inequality. Instead, the continued growth in income inequality in the 2000s was accounted for primarily by increases in female earnings inequality and declines in both male and female employment.
