Does corruption affect income inequality and poverty?

This paper provides evidence that high and rising corruption increases income inequality and poverty. An increase of one standard deviation in corruption increases the Gini coefficient of income inequality by about 11 points and income growth of the poor by about 5 percentage points per year. These findings are robust to use of different instruments for corruption and other sensitivity analyses. The paper discusses several channels through which corruption may affect income inequality and poverty. An important implication of these findings is that policies that reduce corruption will most likely reduce income inequality and poverty as well.

Global estimates of growth–inequality–poverty (GIP) triangle: evidence from World Bank’s classification countries

This study extended the concept of ‘growth–inequality–poverty (GIP) triangle’ by using the principle component approach which allows us to composite different poverty and inequality indicators into one single index that contains most of the useful information from the original dataset. Using the idea of GIP triangle, this study examines the long-run relationship among weighted poverty index (which comprises headcount ratio, poverty gap and squared poverty gap); weighted inequality index (i.e., Watts Index, Gini Index and MLD Index) and average monthly per capita income in the designated 138 countries according to World Bank’s classification over a period of 2005–2010. The data set mainly contain countries’ unit record household survey at least one which is conducted between the countries during the sample period. The regression model encompassing the impact of economic growth and income inequality on poverty reflects that income inequality increases poverty while economic growth decreases poverty. It indicates that the impact of inequality in increasing poverty is a somewhat greater than that of growth in average income in reducing overall poverty in a sample countries. The other regression model encompassing the impact of economic growth and poverty on income inequality showed that the poverty itself is also likely to be a barrier for poverty reduction; and inequality seems to predict lower future growth rates. The final regression model depicting the impact of poverty and income inequality on mean income of the household suggests that poverty itself reduces mean income of the household while income inequality increases economic growth. The results are interesting and simply suggest that whenever social institutions malfunction, the incidence of damage would usually be distributed unevenly over the society’s members.     

Homelessness and Inequality

Homelessness and housing insecurity in the United States are not so much a housing problem or a poverty problem as a visible sign that growing wealth inequality has left millions of people unable to earn enough to afford adequate housing. The classical economists David Ricardo and Henry George linked wealth inequality by arbitrage to unequal income and wages. The greater the inequality of wealth, the greater the inequality of income and the lower the wages at the bottom. Neoclassical economics has largely obscured this relationship. Consequently, proposals from both conservatives and liberals to address homelessness focus narrowly on housing. Ultimately, reducing wealth inequality requires national tax reform and a return to vigorous antitrust enforcement. However, cities can reduce local inequality by making property tax assessments uniform, or, better yet, by shifting to taxing land only.     

REGIONAL SHORT-RUN EFFECTS OF TRADE LIBERALIZATION IN BRAZIL

We use a single-country multi-regional computable general equilibrium model to evaluate regional short-run impacts of reduction in import tariffs resulting from recent free trade area agreements, on poverty and distribution of income in Brazil. Results show that trade can reduce inter-regional income inequality, but poor urban households lose with trade liberalization. Trade policy alone is not sufficient for achieving more equitable income distribution goals in Brazil. Without greater investment in human and physical capital, incomes in most regions of Brazil are likely to lag behind incomes in the South/Southeast, the most developed regions in the country.     

The Effect of Income Distribution on the Ability of Growth to Reduce Poverty: Evidence from Rural and Urban African Economies

The present study examines the extent to which income distribution affects the ability of economic growth to reduce poverty, based on 1990s data for a sample of rural and urban sectors of African economies. Using the basic‐needs approach, an analysis‐of‐covariance model is derived and estimated, with the headcount, gap, and squared gap poverty ratios serving as the respective dependent variables, and the Gini coefficient and PPP‐adjusted incomes as explanatory variables. The study finds that the responsiveness of poverty to income growth is a decreasing function of inequality, albeit at varying rates for the three poverty measures: lowest for the headcount, followed by the gap and fastest for the squared gap. The ranges for the income elasticity in the sample are estimated at: 0.02–0.68, 0.11–1.05, and 0.10–1.35, respectively, for these poverty measures. Furthermore while, on average, the responsiveness of poverty to income growth appears to be the same between the rural and urban sectors, there are substantial sectoral differences across countries. The results suggest the need for country‐specific emphases on growth relative to inequality.     

Mobility and the dynamics of poverty in Iran: Evidence from the 1992–1995 panel survey

In the last three decades, revolutionary Iran has experienced large shocks to its political and economic system with likely effects on poverty, inequality, and economic mobility. While poverty has declined, inequality has remained relatively high and stable over nearly four decades. In this paper, for the first time, we examine poverty and inequality in a dynamic context using a 4-year panel data, collected during 1992–1995. We show that short-term income mobility is relatively high, which helps mitigate persistent high inequality. We offer a range of estimates of transition probabilities, indicating that, for example, someone in the lowest (highest) quintile has between 25% and 50% chance of moving up (down) the income ladder. Focusing on the dynamics of poverty, we distinguish between short- and long-term poor and between chronic and transient poverty. Surprisingly, we find that chronic poverty is a more serious problem in urban than rural areas, while transient poverty is geographically more uniformly distributed. Finally, using Tobit and quantile regression, we examine the correlates of these two types of poverty. Both chronic and transient poverty are higher for households headed by women and by younger and less educated men. While minorities suffer more from transient poverty, they are less likely to be chronically poor. We discuss the implications of these findings for policy to alleviate chronic and transient poverty.     

Distributional effects of imputed rents in five European countries

Most empirical distributional studies of well-being in developed countries rely on distributions of disposable income. From a theoretical point of view this practice is contentious since a household’s command over resources is determined not only by its spending power over commodities it can buy in the market but also on resources available to the household members through non-market mechanisms such as the in-kind provisions of the welfare state and the value of private non-cash incomes. In developed market economies the most important private non-cash income component is imputed rent from owner-occupied or subsidized accommodation. Employing a wider definition of imputed rent that also allows the analyst to capture income advantages among tenants living in rent-subsidized accommodations of various sorts (including rent-free or reduced-rent households), the present paper examines the differential effects of including imputed rents in the concept of resources in five European countries (Belgium, Germany, Greece, Italy and the UK). The results suggest that in almost all cases, the inclusion of imputed rents in the concept of resources leads to a decline in measured levels of inequality and poverty. The main beneficiaries are outright homeowners and households living in rent-free (or heavily subsidized) accommodation—most often older persons. The inclusion of imputed rents in the concept of resources does not lead to substantial changes in the ranking of the countries according to their level of inequality, despite widespread differences in the rates of home ownership and subsidization across the countries studied here.

Can innovation improve income inequality? Evidence from panel data

Income inequality is a source of social instability and armed conflict, which in turn are detrimental to economic development. This study examines the role of innovation in income inequality in twenty-three developed countries, using a panel mean group estimator that takes cross-sectional dependence into consideration. Three income inequality indicators are used: the Standardized World Income Inequality Database (SWIID), the University of Texas Inequality Project (UTIP), and the Estimated Household Income Inequality (EHII). The innovation indicators are patent applications and patents granted. The empirical results based on the common correlated effect mean group (CCEMG) reveal that innovation widens income inequality. We also investigate whether the innovation–income inequality nexus is subject to a country’s level of globalization and financial development. The findings suggest that the interaction terms between innovation with these two variables have positive effects on income inequality, whereas innovation failed to reduce income inequality. Globalization and financial development are found to drive income inequality. The empirical results are robust to different income inequality and innovation measures as well as estimation techniques.

The Distributional Effects of Tax‐benefit Policies under New Labour: A Decomposition Approach*

I revisit the distributional effects of tax‐benefit policy reforms under New Labour using counterfactual microsimulations embedded in a Shapley decomposition of time change in inequality and poverty indices. This makes it possible to quantify the relative effect of policy changes compared to all other changes, and to check the sensitivity of this policy effect to the use of (i) income vs. price indexation, and (ii) base vs. end period data. Inequality and poverty depth would have increased, and the sharp fall in child poverty would not have occurred, had the reforms of income support and tax credits not been implemented.     

Boom, bust, and the poor: Poverty dynamics in the Middle East and North Africa, 1970–1999

This paper analyzes changes in poverty and inequality in the Middle East and North Africa. It finds that the structural relationship between poverty reduction, income growth and distribution is the same for MENA and other developing economies. Prior to 1985 rapid growth sharply reduced poverty. After 1985, despite very low income growth, a rising share of income accruing to the lowest quintile meant that the average income of the poor rose more rapidly than that of the non-poor. These unusual poverty dynamics were primarily due to international migration. Remittances both increased per capita incomes in labor exporting countries and increased the share of income accruing to the poor.

Linkages between income inequality,international remittances and economic growth in Pakistan

This paper explores the dynamic linkages between income inequality, international remittances and economic growth using time series data over the period of 1976–2006 in case of Pakistan. The cointegration analysis based on the bounds test confirms the existence of a long-run relationship between income inequality, international remittances and economic growth. Our results reveal that income inequality and international remittances enhance economic growth. The causality analysis based on innovative accounting approach shows bidirectional causal relationship between income inequality and economic growth and same is true for international remittances and income inequality. International remittances are cause of economic growth but not vice versa. Although we find support for Kuznets hypothesis but Pakistan is yet to benefit, in terms of reducing the gaps of income inequality, from the international flow of remittances and economic growth. The paper argues that, from a policy perspective, there is an urgent need for policy makers in Pakistan to reduce the widening gap of income inequality by focusing on income redistribution policies and to go beyond the traditional factors in balancing income inequality.     

Macroeconomic Adjustment and the Poor: Analytical Issues and Cross‐Country Evidence

Abstract.  This paper studies the links between macroeconomic adjustment and poverty. The first part summarizes some of the recent evidence on poverty in the developing world. The second reviews the various channels through which macroeconomic policies affect the poor, whereas the third is devoted to the specific role of the labor market. It presents an analytical framework that captures some of the main features of the urban labor market in developing countries and studies the effects of fiscal adjustment on wages, employment, and poverty. The fourth part presents cross‐country regressions linking various macroeconomic and structural variables to poverty. Higher levels and growth rates of per capita income, higher rates of real exchange rate depreciation, better health conditions, and a greater degree of commercial openness lower poverty, whereas inflation, greater income inequality, and macroeconomic volatility tend to increase it. Moreover, the impact of growth on poverty appears to be asymmetric; it seems to result from a significant relationship between episodes of increasing poverty and negative growth rates.     

Corruption control,shadow economy and income inequality: Evidence from Asia

Developing countries often suffer from high corruption, high income inequality and poor institutional arrangements that give rise to large shadow economies. Earlier evidence shows that shadow economies moderate the negative effects of corruption on income inequality in highly unequal South American countries. For Asia, we show that the persistence of shadow economies raises inequality even if corruption control is strong. Supported by static and dynamic panel data analyses of 21 countries in Asia between 1995 and 2015, we show that in order to combat rising inequality, corruption control must be complemented by the ability to translate secondary and tertiary school enrolment into industrial and, more importantly, service sector jobs. Countries with low corruption but high inequality can reduce inequality by committing to higher public consumption expenditures. Further, combining greater trade openness with low corruption lowers inequality, except for countries in South Asia.     

Income distribution and well‐being: what can we learn from subjective data?

Abstract. How does the income of others affect my own welfare? This survey of the empirical literature stresses the contribution of subjective data to the understanding of this issue, with an attempt to disentangle direct effects (preference interdependence) from indirect informational effects. It shows that perceived mobility is central to the link between other people's income and individual satisfaction, as it determines individual opportunities and risks. Agents also appreciate the egalitarian nature of mobility itself, so that individual welfare depends on dynamic inequality rather than static income distribution. These studies illustrate how subjective data can bring information on aspects of utility and social interactions that are beyond the scope of the method based on action‐revealed preferences.     

The distributional implications of tax and transfer programs in US

The distributional consequences of changes in tax laws and transfer programs in the United States are studied. Using detailed household income data from the Panel Study of Income Dynamics (PSID) from 1981–91, income inequality is measured for both pretax/transfer and post-tax/transfer definitions of household income. A new statistical methodology for assessing the impact of changes in taxes and transfers on the size distribution of income is utilized. Confidence intervals are constructed for various measures of inequality, and hypothesis tests are conducted to determine whether observed changes in the distribution of income due to taxes and transfers are statistically significant. Using decomposable measures of inequality, the implications of type of tax table used are investigated.     

Bridging Africa’s income inequality gap: How relevant is China’s outward FDI to Africa?

This study examines whether: (i) the remarkable inflow of Chinese FDI to Africa matters for bridging the continent’s marked income inequality gap, (ii) Africa’s institutional fabric is effective in propelling Chinese FDI towards the equalisation of incomes in Africa and (iii) there exist relevant thresholds required for the various governance dynamics to cause Chinese FDI to equalise incomes in Africa. Our results, which are based on the dynamic GMM estimator and macrodata for 48 African countries, reveal the following. First, although Chinese FDI contributes to fairer income distribution in Africa, the effect is weak. Second, although Africa’s institutional fabric matters for propelling Chinese FDI towards the equalisation of incomes across the continent, governance mechanisms for ensuring political stability, low corruption, and voice and accountability are critical. Finally, the critical masses required for these three key governance dynamics to cause Chinese FDI and other income inequality-reducing modules to reduce income inequality are 0.8, 0.5 and 0.1, respectively. These critical masses are thresholds at which governance is necessary but no longer sufficient to complement Chinese FDI to mitigate income inequality. Hence, at the attendant thresholds, complementary policies are worthwhile. Policy recommendations are provided in the conclusion.     

DOES EDUCATION REDUCE INCOME INEQUALITY? A META‐REGRESSION ANALYSIS

This paper reexamines the effects of education on inequality through a comprehensive meta‐regression analysis of the extant empirical literature. We find that education affects the two tails of the distribution of income: Education reduces the income share of top earners and increases the share of the bottom earners. Education has been particularly effective in reducing inequality in Africa. Some of the results suggest that secondary schooling appears to have a stronger effect than primary schooling, though this finding is not always robust. The heterogeneity in reported estimates can be largely explained by differences in the specification of the econometric model and measure of inequality and education.
