Long term trends in fair and unfair inequality in the United States

This article analyses the microeconomic sources of wage inequality in the United States from 1967–2012. Decomposing inequality into factors categorized by degree of personal responsibility, education explains over twice as much of inequality today as 45 years ago. However, neither hours worked nor education, industry, marital status, or geographical location can explain the rise in income inequality. In fact, ‘unfair’ inequality (income disparity derived from non-responsibility factors) has risen faster than ‘fair’ inequality (income disparity derived from responsibility factors), regardless of the set of variables chosen as fair sources of inequality. We further examine income inequalities within gender and racial groups, finding substantial heterogeneity. Overall, using micro data to understand the sources of inequality and how these changes over time can provide better information for policymakers motivated to combat rising inequality.     

Status-seeking behavior,the evolution of income inequality,and growth

Using an overlapping generations model, this paper investigates the implications of status-seeking behavior, induced by preferences for relative income, for the evolution of income inequality. When average income rises, an individual’s marginal utility of their own income may increase (keeping up with the Joneses, or KUJ), or decrease (running away from the Joneses, or RAJ). It is shown that income inequality is shrinking over time in the KUJ economy, whereas it is expanding in the RAJ economy. We also explore the implications for long-run growth and inequality, in the existence of both KUJ and RAJ agents.

Earnings Mobility during the Transition: The Case of Hungary

This paper tests the hypothesis that the economic transition if associated with earnings mobility that is higher than in mature market economies, and which offsets the increase in earnings inequality. It uses the Hungarian Household Panel Survey for the period 1992-1997. The paper finds that indeed five-year earnings mobility in Hungary in the early years of the transition was significantly higher than in OECD countries. However, there are sings that the mobility rate has begun to decline. The pattern of earnings mobility had a significant equalizing effect: low earners were raised up while high earners were leveled down. However, mobility was taking place against a backdrop of the fall in real wages and therefore in most cases it implied the worsening of the absolute earnings status. Unfortunately, mobility does not help much low-paid workers. In contrast to most OECD countries, in Hungary low-paid workers have little chances to move up the earnings ladder. Low-paid jobs tend to be a permanent trap rather than a stepping stone to better paid employment.     

Growth and income inequality: a canonical model

Summary. We develop an endogenous growth model with elastic labor supply, in which agents differ in their initial endowments of physical capital. In this framework, the growth rate and the distribution of income are jointly determined. The key equilibrating variable is the equilibrium labor supply. It determines the rate of return to capital, which in turn affects both the rate of capital accumulation and the distribution of income across agents. We then examine the impact of various structural shocks on growth and distribution. We find that faster growth is associated with a more unequal, contemporaneous distribution of income, consistent with recent empirical findings.Received: 7 October 2004, Revised: 18 February 2005, JEL Classification Numbers: O17, O40.Cecilia García-Peñalosa: Correspondence toGarcía-Peñalosa would like to acknowledge the financial support received from the Institut d’Economie Publique (IDEP), Marseille.

Income inequality and FDI: evidence with Turkish data

This article explores how foreign direct investment (FDI) and other determinants impact income inequality in Turkey in the short- and long-run. We apply the nonlinear auto-regressive distributed lag (ARDL) modelling approach, which is suitable for small samples. The data for the study cover the years from 1970 to 2008. The empirical results indicate the existence of a co-integration relationship among the variables with asymmetric adjustment of the income distribution in the short- and long-run. The negative impact of FDI on the Gini coefficient, decreasing income inequality, is statistically significant in the short- and long-run, though with a quantitatively small impact in both cases. In the short run, GDP growth increases inequality initially, an effect that is reversed in the next period, increases in domestic gross capital formation decreases inequality, and increases in the literacy rate have very minor adverse effects on income equality. However, in the long run these variables have no statistically significant effects on the Gini coefficient. A reduction in the population growth rate reduces inequality in the short run but has no effect in the long run, whereas an increase in the rate reduces inequality in the long run but has no effect in the short run.     

Income inequality, democracy and growth reconsidered

Is inequality harmful for growth? Am. Econ. Rev. 84, 600–621) as well as Alesina and Rodrik (Alesina, A., Rodrik, D., 1992. Distribution, political conflict, and economic growth. In: Cukierman, A., Hercowitz, Z., Leiderman, L. (Eds.), Political Economy, Growth, and Business Cycles. MIT Press, Cambridge, MA, pp. 23–50; Alesina, A., Rodrik, D., 1994. Distributive politics and economic growth, Q. J. Econ. 109, 465–490) have argued that income inequality reduces economic growth rates among democracies because it promotes distributional struggles. In this paper I question the supportive evidence for a number of reasons. Measures of income distribution and democracy are unreliable and permit only very tentative conclusions. Changes in data sources or recoding of some influential cases affect results. It is questionable whether equality effects on growth apply only within democracies, as a median voter interpretation of this relationship should make one expect. The general idea that distributional struggle hurts the growth prospects of nations, however, receives some empirical support.     

我国收入不平等、金融发展和消费需求波动的实证研究:1978～2001

本文考察了收入不平等与总消费需求变动之间的联系,在高收入地区,不平等程度越大似乎消费需求波动越大,而在低收入地区,收入不平等越大,消费需求波动反而较小。本文找到证据表明金融发展水平能有助于解释为什么收入分配在高收入和低收入地区中影响消费需求的短期波动是不同的,本文的政策含义是,加快低收入地区如中西部的经济和金融发展步伐,加大金融发展相机调整的力度。     

Finance,income inequality and income redistribution

Using a panel fixed effects model for a large sample of countries covering 1975–2005, we test the hypothesis that income inequality caused by finance (financial development, financial liberalization and banking crises) is related to more income redistribution than inequality caused by other factors. Our results provide evidence in support of this hypothesis. We also find that the impact of inequality on redistribution is conditioned by ethno-linguistic fractionalization. Our findings are robust to the inclusion of several control variables suggested by previous studies.     

The determinants of female labour supply in Hungary

The aim of this paper is to closely examine the effect on a married woman's labour supply decision of non-labour income and of her own wage rate in a transition economy. The paper first shows that labour force participation rates for Hungarian females, though decreasing, were still extremely high and comparable to male economic activity in western countries. It then estimates labour supply parameters using a model that controls for sample selection issues associated with the labour supply of married women. Wage elasticity is estimated to be high and positive (1.81) while the income effect is consistent with leisure being a normal good. No sample selection bias is found.     

弱势就业群体的就业与再就业问题探讨

在我国社会转型、体制转轨的背景下，由于社会保障制度的建立与改革滞后，弱势就业群体的范围和数量不断扩大，他们与其他群体之间的差距加大，其社会心理动荡强烈，日益被边缘化。因此，研究弱势就业群体的就业与再就业问题具有十分重要的现实意义。     

匈牙利科技观察

匈牙利每年投入研发经费10亿欧元左右,约占全国GDP的1％。根据新政府的设想,到2020年,研发投入将提高到GDP的1．5％～1．8％。匈牙利国际科技合作活跃,近年来采取多种办法解决人才流失问题,并吸引海外人才回流。根据国家中期科技和创新战略（2007-2013年）,未来匈牙利要形成知识和创新驱动型经济,以确保匈牙利有能力向国际市场提供有竞争力的产品和服务。匈牙利近年确定了一些高校为研究型大学,加强了对产业集群的引导和支持。但是匈牙利仍面临研究经费不足和人才流失的挑战。     

中国就业发展新论——核心就业与非核心就业理论分析

正如企业创新作为市场经济的基本动力受到忽视 ,核心就业作为市场就业的基础在中国经济改革以来一直没有受到足够重视 ,因此造成了今天就业发展特别困难的局面。核心就业是指直接参与、引导、促进和扶持企业创新活动的那部分就业。在长期 ,核心就业的兴衰决定了市场经济中总体就业的兴衰。中国企业的核心就业水平目前仅达到 2 5%左右 ,总体核心就业水平达到 3 0 %左右。为了达到 80 %左右的市场一般核心就业水平的目标 ,中国需要改变现行的国有企业改革模式 ,建立政府权力均衡机制 ,以良性发挥政府功能 ,以及完善农村的改革和发展道路等各项政策措施。     

Developing transition pathways for a low carbon electricity system in the UK

This paper describes the approach to developing transition pathways for a low carbon electricity system in the UK, being pursued in a major new inter-disciplinary research project. The project aims (a) to learn from past transitions to help explore future transitions and what might enable or avoid them; (b) to design and evaluate transition pathways towards alternative socio-technical energy systems and infrastructures for a low carbon future; and (c) to understand and, where appropriate, model the changing roles, influences and opportunities of large and small ‘actors’ in the dynamics of transitions. The paper describes the approach, which builds on the work of Dutch researchers on transitions and transition management using a multi-level framework of niches, socio-technical regime and landscape, as well as on other parts of the innovation systems literature. It also describes its application to several outline transition pathways to a low carbon energy system in the UK. The pathways embrace both the evolution of the physical and institutional infrastructure changes and the roles of both large actors, e.g. multinational energy supply and distribution companies, national governments, major investors, and small actors, e.g. households, innovators and entrepreneurs.     

Calculation and decomposition of income inequality in low- and middle-income countries: a survey data analysis

This article estimates income inequality in a sample of four low- and middle-income (LMI) countries namely; Albania, Nepal, Tajikistan and Tanzania using the household survey data – Nepal Living Standard Measurement Survey Second. First, we estimate the income generation function for each country and calculate the income inequality using Gini index (GI). Second, we decompose the income Gini into the determinants of income generation functions. Based on the decomposition result, socio-economic factors are the most important determinants of income inequality followed by geographic factors. Demographic factors have the least effect on income inequality in all four countries. Third, we propose a new method to quantify the effect of change in each covariate of income generation function on income Gini. That allows us to quantify the effects of change in specific policy such as increase in investment in schooling or public health to specific group of the population in society on income inequality. A carefully chosen, integrated policy can significantly reduce inequality in all four countries under study.     

Output decline and the demise of the CMEA and the USSR: The case of Hungary

The direct effect of market losses in CMEA on Hungarian output was 4%, out of the 18% decline registered in gross output in 1988–1992. Total (direct and indirect) effects amounted to 8%. In the same period Hungary's export expansion in western markets led to direct and total effects equivalent to 2.9% and 5.6% of the 1988 output, respectively. The share of reorientation within this switch from east to west was not negligible, it amounted to 19% of respective trade volumes. The 1991 price explosion of imported inputs inhibited the activity of Hungarian firms only moderately, due to earlier realistic domestic prices. In 1991 Hungary suffered a 26% terms of trade loss, and could have experienced an income terms of trade loss of USD 1400 to 1600 million, had the trade volume of 1990 been repeated. Since adjustments in 1991, much smaller income losses accrued. Due to earlier special tax arrangements, much of the burden of terms of trade losses had to be born by the budget.     

Real exchange rate and exchange rate policy in Hungary

Five real exchange rate indicators are computed to assess the international competitiveness of Hungarian industry. These indicators are explained in econometric equations by employment, unemployment, productivity, interest spread and real producer wage. Causality tests reveal that external performance has an impact on real exchange rates, and contributes to explaining real exchange rates. There is very limited scope for policy intervention to constrain the negative effects of capital inflows without incurring other costs.     

On the dynamics of inequality

The dynamics of inequality are studied in a model of human capital accumulation with credit constraints. This model admits a multiplicity of steady state skill ratios that exhibit varying degrees of inequality across households. The main result studies equilibrium paths. It is shown that an equilibrium sequence of skill ratios must converge monotonically to the smallest steady state that exceeds the initial ratio for that sequence. Convergence is “gradual" in that the steady state is not achieved in finite time. On the other hand, if the initial skill ratio exceeds the largest steady state, convergence to a steady state is immediate.This paper is based on unpublished notes from 1990; see http://www.econ.nyu.edu/user/debraj/DevEcon/Notes/incdist.pdf. Two considerations suggest that these results may be worth reporting in print. First, the existence of a sizeable recent literature indicates that these relatively early notes may have value outside a filing cabinet or a private webpage. Second, Mukul Majumdar’s own research on economic growth with a nonconvex technology is an even earlier precursor to some of this literature, so the current outlet – a special issue in his honor – seems appropriate. Conversations with Glenn Loury simplified the proof of the main result. I thank Dilip Mookherjee for many useful discussions, and two anonymous referees for helpful comments on an earlier draft. Funding from the National Science Foundation under grant number 0241070 is acknowledged. This paper is dedicated with much affection and warm admiration to Mukul Majumdar – or to Mukulda, as I always think of him – on the occasion of his 60th birthday.     

Measuring fossil resource inequality—A case study for the UK between 1968 and 2000

This paper quantifies fossil resource inequalities amongst income quintiles in the UK between 1968 and 2000. It calculates a resource-based Gini coefficient using an input-output based resource allocation model.The results show that the Gini coefficient for total fossil resource consumption grew by 24% over the time period. By comparison the Gini coefficient for overall household expenditure rose by only 13%. The increase in resource inequality was prompted by the rising demand by high income quintiles for goods and services such as: “fuel and light” (heating and lighting the home), “car use” (private transportation), “recreation”, “travel” and “other services”. The analysis shows further that the Gini coefficient for “direct” fossil resources (“fuel and light” and “car use”) was lower and rose less steeply than the Gini coefficient for fossil resources embodied in other goods and services (indirect fossil resource requirements).Investigation into the drivers behind direct and indirect resource inequalities suggests a number of policy conclusions. Firstly, it is clear that policy initiatives to reduce fossil resource requirements (and the associated climate change impacts) must pay careful attention to distributional differences. Additionally, increased attention needs to be paid to the inequalities associated with indirect fossil resources consumption as well as the more visible direct resource inequalities.
