Unequal access to education and income distribution

Summary This paper attempts a new specification of the education variable in accounting for differences in income distribution in a cross-sectional analysis of 49 countries. The specification refers to the steepness of the educational pyramid, as measured by the coefficient of variation of enrolments within a given country. This variable alone explains 23 per cent of income inequality across countries (as measured by the Gini coefficient), while in the presence of it the traditional (catch-all) per capita income variable becomes insignificant.This finding indicates the importance of the supply side in relative income determination. It is also suggestive that a policy aiming at equalisation of access to the different levels of education might help in reducing income inequality.I would like to thank Arnold Anderson, Mary Jean Bowman, Jan Tinbergen and Peter Wiles for commenting on an earlier draft of this paper.     

Europe’s Demographic Deficit A Plea For A Child Pension System

Summary This paper considers the economic implications of the stalling birth rates and demographic development in Europe. To remedy for this it proposes a child pension system. This system allows additional pension facilities depending on the number of children raised. It should be a PAYG pension financed with an income tax. The main motivation for this is that parents have invested resources which also benefit society.18th Tinbergen Lecture, Amsterdam, October 22, 2004Ifo Institute for Economic Research at the University of Munich.I am grateful to Lans Bovenberg and Peter Cornelisse for useful conversations about the Dutch pension system and Tinbergens views on children and pensions.

Trade openness and income inequality in China and the SAARC Region

The paper empirically examines the effects of trade liberalisation on income inequality in China and the South Asian Association for Regional Cooperation countries. Panel data analysis is conducted for the period of 1973 to 2012. The results show that liberal trade policies have increased income inequality in these countries. These results are robust to alternative liberalisation measures. The control variables used have differing effects on income distribution. Per capita income has an increasing effect on income inequality, while education, financial development, financial openness, democracy, and government size are shown to reduce income inequality. These outcomes can be expected to have important policy implications for the use of trade liberalisation in these countries.     

The Economics of Health System Payment

Summary Health care takes up 10 to 15 percent of GDP in most countries. In this lecture, I consider the efficiency of the medical system, focusing on the potential for payment reform to increase efficiency. Traditionally, medical care reimbursement has been based on the quantity and intensity of the services provided. While this system encouraged valuable innovation, it failed when high quality is not achieved by increased quantity. In theory, a more efficient system could be achieved by paying for medical care on the basis of quality of care provided, not just quantity. I discuss the design of such a payment system and review the literature on how pay-for-performance systems have worked in practice. Cautious optimism about the potential for efficiency gains from payment reform is warranted. This essay was presented as the 19th Tinbergen Lecture on October 21, 2005, in Amsterdam. I am grateful to session participants for comments.     

The Supply Side of the Race Between Demand and Supply: Policies to Foster Skill in the Modern Economy

In his celebrated book on income inequality, Jan Tinbergen (1975) wrote about the race between demand and supply in determining the evolution of wages and inequality. The demand side of the recent labor market is well understood. Skill-biased technical change favors skilled workers in many different economic environments. The supply side is less well understood. In the Netherlands, until recently, the supply side was winning and the returns to education were declining or stagnant. The exact reasons for this phenomenon are not well understood. Recently, however, there is evidence that suggests that the returns to schooling are increasing and that demand is outstripping supply, as it has done in most developed countries around the world. This has produced rising wage inequality. Unless more active supply side measures are undertaken, this trend is likely to continue. This problem, joined with the persistent problem of immigrant assimilation and the growing role of immigrants in the Dutch economy, renews interest in the supply side of the labor market. This lecture examines the determinants of the supply of skills in the short run and the long run. It examines the roles of short- term credit constraints and long-term family factors in fostering or retarding skill accumulation. It summarizes the evidence on a number of policy proposals to foster skills including early childhood programs, programs to alleviate short-term financial pressure, job training and second chance programs, and tax policies. This lecture stresses the cumulative dynamic nature of skill production and the importance of recognizing that skill begets skill in designing suitable policies to reduce inequality and foster economic growth. While the evidence is based on American data, the lessons are relevant for economies around the world. Specific lessons for the Netherlands are emphasized.     

On the theory of macroeconomic policy

Summary Jan Tinbergen originated the theory of policy in the 1950s. Here I apply it to contemporary macroeconomics. The two standard instruments of short-run demand management cannot achieve the two usual targets, full employment and price stability. With respect to those goals, these two instruments are collinear, except for small and transient effects on foreign exchange rates. But the mix of fiscal and monetary policies, relative to one another, does have important effects on the composition of national output, as between investment and consumption.I point out that policy-makers, like portfolio managers, should diversify the instruments they use when they are uncertain of their effects. I discuss some pitfalls in the empirical estimation of policy effects, especially possible misinterpretations of simple correlations, and I note that policy rules cannot be invariant to changes in macroeconomic structure. I argue that policy rules should involve responses to new information and in practice allow discretion. Finally, I suggest that Tinbergen's theory of policy needs to be extended to policy coordination among nations.Third Tinbergen Lecture delivered on October 20, 1989, in Utrecht for the Royal Netherlands Economic Association.     

Social Justice and open coordination in Europe.

In his Tinbergen lecture Jacques Drèze broaches two interesting themes. He argues, firstly, that we have failed to develop an efficient instrument for income insurance on behalf of potentially low-skilled workers; wage subsidies are such an instrument. Secondly, he argues that labour market integration in an economic union like the EU entails externalities, resulting in underprovision of insurance; coordination or matching grants could overcome that second inefficiency. I largely share Drèze's policy paradigm. Yet, I believe enhancing social justice in the European Union requires, at this stage of European cooperation, a different methodology of policy coordination, which has recently been coined 'open coordination.' I will develop my argument in favour of 'open coordination' with reference to the two themes Drèze discusses.     

A decomposition analysis of income inequality of Chinese rural households

This paper reports an application of household survey data collected from grain producing areas in five provinces of China to issues of the determinants of rural inequality. Previous studies suggest that non-agricultural activities have been the major cause of rural income inequality, which has important implications for policy formulation. However, our results show that inequality within the grain producing areas was also very high, with differences in crop income as the major source of inequality. The policy implications are also different from those of previous studies. While some suggest that an increase in agricultural income can reduce inequality, our results indicate that this is not universally true. In some cases, whether the increase in crop income has come from state procurement also matters. These results call for a more cautious and area-specific approach to policy formulation as far as inequality is concerned.     

The distribution of ncome in the UK and OECD countries in the twentieth century

Distributional changes are an important part of the economichistory of the OECD countries over the twentieth century. Inthe UK, income inequality in the 1970s was substantially lowerthan 40 years earlier, and is now much higher than in 1979.The pattern of change in the USA has similarities to that inthe UK, but other countries have exhibited significant differences.In order to explain diversity of experience over time, and differencesin income inequality across countries today, we need to recognizethat the distribution of income is subject to a variety of forces,affecting earnings, wealth, and income. These forces includethe policy choices made by governments affecting market incomesand fiscal redistribution. What we need to explain is why insome periods a number of these forces combine to produce episodesof rising, or falling, inequality. Any single theory, such asthat based on a global shift of demand away from unskilled workers,cannot provide a fully adequate explanation.

Introduction to income inequalities and redistribution in china

This special section presents the main findings about long-run trends in inequality in China and its driving factors as they emerge from a country case study carried out under a UNU-WIDER supported project.¹ Special focus in the umbrella project were on three issues: (i) the role of earnings inequality and its determinants; (ii) the role of top incomes when administrative records or other sources can be combined with household surveys; and (iii) the redistributive impact of public policies. Main findings of the project including those for China results were presented in a special panel during the UNU-WIDER Think Development – Think WIDER development conference held in Helsinki in September 2018.²

1. Motivation

Inequality has once again emerged as a major issue in economic development across the developed and developing world, and addressing this challenge is key in the UN Sustainable Development Agenda. The UNU-WIDER conference on Mapping the Future of Development Economics held in Helsinki in September 2016³ led to the formulation of a project to study inequality in five major developing countries accounting for more than 40 per cent of the world’s population. UNU-WIDER implemented these studies under its Inequality in the Giants project,⁴ designed as part of a broader international effort to shed light on a set of new questions on between-country and within-country inequalities, by generating integrated datasets and applying a consistent methodology to investigate the determinants of inequality dynamics in some of the world’s largest economies. China was included among the five case countries, and the effort included both a series of papers on China, produced under the coordination of Professor Shi Li and various workshops and meetings. Coming to grips with inequality in China is an obvious priority for anyone interested in trends in global inequality; and the present special section contains five key papers produced in the context of the UNU-WIDER project and subsequently accepted for publication by the China Economic Review.

2. Content of the special section

The five papers on inequality in China presented in this special section cover different topics and jointly illustrate a key set of important themes in the recent evolution of China’s income distribution.The opening study by Luo, Li, and Sicular (LLS) provides an overview and analysis of the long-term evolution of inequality in China, while the next three papers — on urban wage inequality, public transfers, and top incomes — each illustrates and delves more deeply into important aspects of the broader trends in inequality.What are the main findings of these papers? The core finding is that inequality in China rose markedly from the 1980s through the early 2000s; only since 2008 has the upward trend stopped or reversed. LLS report and examine the underpinnings of this core finding, using the five waves of the China Household Income Project surveys conducted during 1988-2013. This paper also finds a considerable, ongoing reduction in rural poverty, and a poverty decomposition analysis indicates that this poverty reduction was mostly due to income growth rather than redistribution in rural areas.The second paper by Gustafsson and Wan (GW) is on urban wage inequality from 1988 to 2013 and it sheds further light on the changes in the distribution of wage earnings. The authors highlight that average wages have grown rapidly and that wage inequality increased until 2007. Moreover, age has become weaker and education stronger related with wage. Importantly, the gender wage gap once small widened rapidly between 1995 and 2007, and workers in foreign owned firm and the state sector enjoy a wage premium.While wages are the most important component of income, it is only part of the inequality story. One important additional question is the role of government taxes and transfers. Since the early 2000s, China has embarked on a major effort to put in place a universal social safety net. The study by Cai and Yue (CY), which is the third paper, assess the consequences of these efforts. Their key conclusions include that the same public policy may produce different redistributive implications. Moreover, if the government keeps increasing the social security transfer scale without changing its distribution, then inequality will increase in China. In addition, formal-sector pension takes up the biggest share and is the most un-equalizing sub-item of all social security transfers; and related to the first paper in the special section they argue that the government should spend more on Dibao and rural residents pension to reduce inequality.Arguably, income inequality measured using household survey data understates actual inequality because surveys have difficulty in capturing top incomes. In the Chinese case, concerns about such bias have increased in the past ten years due to the expansion of private wealth and growing numbers of super-rich. The fourth paper by Li, Li, and Wan (LLW) is on top incomes in China and it attempts to correct for this bias using income information for the Chinese super-rich from various sources. They conclude that the Gini coefficient of income inequality increases substantially when samples of top incomes are incorporated.Finally, Gradín and Wu (GW) analyse in the fifth and final study the distribution of income and expenditure in China in a telling comparative perspective with India. Both countries represent two extreme cases in the relationship of inequality using both wellbeing indicators. It emerges that the joint distribution of income and expenditure differs between China and India because there is a higher prevalence of people with a large mismatch between their ranks in income and consumption in India, especially in rural areas, and particularly amongst those reporting low income and high expenditure. The main compositional effects identified are the different demographic and geographical composition of the countries’ populations, mostly the smaller households (especially in rural areas) and the higher level of urbanization in China than in India. The lack of consistency of cross-country comparisons based on income or expenditure calls for the use of hybrid inequality measures combining data on both provided they are available in the same survey.

3. Concluding remarks

The studies brought together in this special section provide telling insights about the trends in inequality in China from which scholars and policy makers can learn a great deal. In a global perspective, further increases in China’s mean income and wealth, both now above the global means, will begin to raise global between-country inequality. This is important in and of itself. Moreover, while we cannot expect that all the world’s poorest countries will follow the same path as China considering that the initial conditions and the international context they face will be very different, the experiences from China do reinforce the observation that much can be done by policy to influence inequality outcomes. In particular, and as argued by Gradin, Leibbrandt, & Tarp, 2020 (forthcoming):“well-functioning labour markets that promote job-creation, decent pay and social inclusion, removing any legal or de facto discrimination based on gender, race, ethnicity or place of origin, providing equal access to human and physical capital, and empowering the most disadvantaged population groups, are a key driver of increased equality”.These insights also emerge clearly from the five China studies in this special section.     

Do International Remittances Affect Poverty in Africa?*

Abstract: International remittances flowing into developing countries are attracting increasing attention because of their rising volume and their impact on recipient countries. This paper uses a panel data set on poverty and international remittances for African countries to examine the impact of international remittances on poverty reduction in 33 African countries over the period 1990–2005. We find that international remittances—defined as the share of remittances in country GDP—reduce the level, depth, and severity of poverty in Africa. But the size of the poverty reduction depends on how poverty is being measured. After instrumenting for the possible endogeneity of international remittances, we find that a 10 percent increase in official international remittances as a share of GDP leads to a 2.9 percent decline in the poverty headcount or the share of people living in poverty. Also, the more sensitive poverty measures—the poverty gap (poverty depth) and squared poverty gap (poverty severity)—suggest that international remittances will have a similar impact on poverty reduction. The point estimates for the poverty gap and squared poverty gap suggest that a 10 percent increase in the share of international remittances will lead to a 2.9 percent and 2.8 percent decline, respectively, in the depth and severity of poverty in African countries. Regardless of the measure of poverty used as the dependent variable, income inequality (Gini index) has a positive and significant coefficient, indicating that greater inequality is associated with higher poverty in African countries, much in conformity with the literature. Similar results were obtained for trade openness. In the same vein, per capita income has a negative and significant effect on each measure of poverty used in the study. Our results also show that inflation rates positively and significantly affect poverty incidence, depth and severity in Africa. In all three poverty measures, the dummy variable for sub‐Saharan Africa is strongly positive, and strongly negative for North Africa. The policy implications of these results are discussed.     

The recent failure of U.S. monetary policy

Summary The very slow growth of the broad money supply has been a primary source of U.S. economic weakness in 1990 through 1992. The velocity link between M2 and the subsequent level of nominal GDP has not declined. But changes in bank reserves brought about by open market operations have had much less effect onM2 than the Fed anticipated for two reasons: (1) reserve requirements now apply to only a small fraction of totalM2; and (2) the new bank capital requirements limit some banks ability to lend. The Federal Reserve failed to appreciate the importance of these conditions and misjudged the strength of the monetary policy stimulus that it was providing.Professor of Economics, Harvard University, and President of the National Bureau of Economic Research.Sixth Tinbergen Lecture delivered on October 2, 1992, in The Hague for the Royal Netherlands Economic Association.     

Carrying forward the Tinbergen initiative in macroeconometrics

Summary The historical roots of macroeconometric model building go back to the studies of Jan Tinbergen in constructing statistical models of The Netherlands and the United States. His work built on the contributions of J.M. Keynes to macroeconomic theory and Simon Kuznets to the design of accounts to measure national income and product. Wassily Leontief's input-output models helped to extend the effort to many industrial sectors. Other economic theorists and statisticians also made important contributions in the 1930s and 1940s. A breakthrough has been the arrival of the electronic computer. Many seemingly impossible tasks are now quite easy. Among the many approaches to economic forecasting, policy analysis, and cyclical analysis, macroeconometric modeling stands out as the most accurate and insightful. There are many challengers, but none that is demonstrably superior on a replicated basis. The present thrust of model building has extended beyond Professor Tinbergen's original work at the national level. World models of economic interdependence are now operational in many international centers.Benjamin Franklin Professor of Economics, University of Pennsylvania.Final draft of the first Tinbergen Lecture delivered on October 24th in The Hague on the occasion of the 125th anniversary of the Royal Netherlands Economic Association.     

Decomposing inequality and poverty in post-war Rwanda: The roles of gender,education, wealth and location

This paper provides an overview of poverty and inequality in post-war Rwanda. Rwanda is one of the poorest countries in the world, and has recently become one of the most unequal. High levels of poverty and inequality have important implications not only in terms of evaluations of social welfare, but also for management of social tensions and the propensity for violent conflict in the future. This paper uses the first two available and nationally representative rounds of household surveys –EICV1 2000 and EICV2 2005 – to decompose and identify the major ‘sources' of poverty and inequality in the country. I find stark differences in vulnerability to poverty by region, gender and widow status of the head of household. I additionally find important changes in the ‘income generating functions' of Rwandan households, and that distribution of land and financial assets are increasingly important in determining the inter-household distribution of income.     

Economic Growth and Income Inequality: Evidence from Dynamic Panel Investigation

This paper empirically investigates the effect of income inequality on economic growth using extended panel data covering a broad range of developing and developed countries. We use system generalized method of moments (GMM) techniques in a dynamic panel analysis, which alleviates the possible positive bias in difference GMM due to the persistence of lagged dependent variables as instruments. We find strong evidence of a negative effect on growth from income inequality, which contradicts the findings of Forbes [2000, September. A reassessment of the relationship between inequality and growth, American Economic Review, 90(4), pp. 869–887] and Li and Zou [1998, October. Income inequality is not harmful for growth: Theory and evidence, Review of Development Economics, 2(3), pp. 318–34]. Further analyses using combined Gini coefficients show that the difference can be overall attributed to the problem of omitted control variables and the differences in how the variations in inequality across countries are reflected. We also find that the negative effects of inequality on economic growth can be of great significance when using a sample of less developed countries or more recent inequality data set.     

Income distribution,basic needs and trade-offs with growth: The case of semi-industrialized Latin American countries

This paper addresses income distribution issues and policy options to eliminate extreme poverty in a particular typology of middle-income semi-industrialized developing countries of Latin America. The countries included in the typology are characterized by a relatively high per capita income (above US$700/yr in 1977), a relatively high degree of industrialization (industry representing over 30% of GNP), a rather large size both in population and area, and relatively well endowed resources in agriculture. A distinctive feature is a strong inequality in the distribution of income and wealth relative to other countries of similar levels of per capita income. The countries included are Brazil, Columbia, Ecuador, Mexico and Peru, representing two-thirds of the population of that region.     

Towards a theory of subsidisation

Summary This paper outlines the conceptual framework of a theory of subsidisation by adapting optimal taxation theory, identifying the appropriate policy maker's welfare functions, and reviewing the uneasy relationship between politics and economics in controlling the distribution of income, information and authority. Introducing involuntary unemployment as an inferior good, new light is shed on the work-leisure choice in social security. Furthermore, it is shown how arguments of altruism and political imposition may be built into traditional welfare functions and how, under the Rule of Law, we are bound to overshoot our targets in the management of entitlements.

收入分配、医疗资源与人口健康:一个跨国研究

收入分配与人口健康的关系是一个争论已久的问题。本文在总结各种理论假说和以往实证研究的基础上,使用新的、质量较好的跨国面板数据,重新检验了收入分配与人口健康的关系。本文的分析重点有二:一是收入分配对人口健康的滞后影响;二是医疗资源在收入分配与人口健康的相关关系中所起的作用。本文的主要发现是,收入不均对人口健康的确有不利影响,但这种不利影响需要10年或更长的滞后期才能充分显现出来,这种滞后性是以往使用固定效应模型的跨国研究未能检测到收入不均与人口健康具有负相关关系的主要原因。此外,医疗资源(特别是初级医疗资源)人均拥有量对人口健康有积极作用;医疗资源有可能通过某种不可观察固定因素对收入分配与人口健康的关系发生影响。这些发现有助于澄清关于收入分配与人口健康关系的争论,对医疗政策也有重要参考价值。     

Intergenerational income mobility and economic freedom

Numerous studies have found that income inequality reduces the chances of upward relative mobility (i.e., climbing up the income ladder). However, most of this work ignores the role played by institutional quality (namely, economic freedom) in determining mobility and increasing the individual's set of choices. We fill this gap by empirically testing the direct and indirect (through economic growth) impacts of economic freedom on intergenerational income mobility. We find that economic freedom has both direct and indirect effects on intergenerational income mobility, while income inequality is a strong predictor of downward income mobility. When we incorporate findings about the purely mechanical relationship between inequality and intergeneration income mobility, we find that the legal system and property rights component of economic freedom matters more than inequality. These results suggest that good institutions can increase intergenerational income mobility.
