In this paper, we compare subjective and money-metric measures of poverty in South Africa using data collected in the 2008/09 Living Conditions Survey. In addition to collecting detailed information on expenditure, the survey asked respondents to...
The aim of this study is to evaluate the feasibility to implement a tax and benefit microsimulation model for Ecuador using EUROMOD as an interface. We first present a detailed description of the main components of the tax and benefit system in...
Changes in relative prices of commodities consumed in different shares across income groups can be expected to alter real income differentials between these groups. Using Mozambican household budget survey and price data from 2002/03 and 2008/09, we...
This paper investigates inequalities across the major black ethnic groups in South Africa, accounting for 80 per cent of the country’s population. We demonstrate that there is an important ethnic gap in the poverty levels of the Xhosa and the Zulu...
This paper presents new evidence on the study of income mobility in Ecuador over the period 2004–11. We utilize longitudinal data of individual income tax returns to measure income mobility both at the top and at the middle of the income distribution...
We reconcile, both theoretically and empirically, changes in inequality with panel income changes over periods of economic growth and decline. We also explore what factors account for the trends of short-run inequality and of inequality in individual...
This study assesses temporal and spatial distribution of child deprivation and income poverty using the fifth and sixth rounds of the Ghana Living Standards Survey. The first-order dominance methodology was used to examine five dimensions of...
Several large-scale efforts have been made to combat malaria in the last decade under the Millennium Development Goals, and while these have led to a...
South Africa has seen a significant increase in the size of the black middle class in the post-apartheid period, but the attitudinal consequences of indicators of the middle class, as of 2011, are inconsistent and modest in size. While members of the...
Changes in the relative prices of commodities consumed in different shares across income groups are known to influence real measures of inequality. Using household budget survey and price data in Mozambique from 2002/03 and 2008/09, we show that...
This paper seeks to measure and explain changes in incomes, inequality, and poverty in Kenya. It starts from a very long-term perspective covering the last century, but then focuses on a more detailed analysis of the recent period for which data from...

International comparisons of average national incomes omit important information about leisure, home production, health, etc. They are also bedevilled by index number problems. This paper suggests ways of combining working hours and life-expectancy...
This paper's goal is to increase the understanding of the inequality trends during the transitional period in China. From 1978 to 1995, China has been undergoing 18 years far-reaching economic system reform and opening to the outside world nationwide...
Single-party political systems exist in a number of countries, such as China and Vietnam. In these countries, party membership is potentially an important source of economic and social status. This paper investigates these effects and the mechanisms...
Natural disasters cause economic damages and may exacerbate disparities in income distribution among countries across the globe. This paper employs satellite data on real-time active fire locations to evaluate the short-term impact of forest fires on...
This report documents VNMOD, the SOUTHMOD model developed for Viet Nam. This work has been carried out by the Central Institute for Economic Management (CIEM) in collaboration with UNU-WIDER and SASPRI. The results presented in this report are...
We study the effectiveness of social protection benefits in reducing income and consumption poverty in five sub-Saharan African countries—Ghana, Mozambique, Tanzania, Uganda, and Zambia—in normal times and times of widespread economic crisis. Using...
We examine inequality convergence over the past three decades and ask if environmentally related impacts on health, and their effect on human capital, are responsible for the slow rate of inequality reduction in countries. Though higher initial...
We study the short-term effect of the introduction of the mandatory disclosure programme for aggressive tax arrangements by focusing on the one introduced in May 2018 under Council Directive 2018/288/EU (or DAC6). Employing bilateral data on cross...
This note describes methods to derive employment-to-unemployment transition shares across industries during the COVID-19 pandemic and to use these shares in SOUTHMOD tax-benefit microsimulation models to adjust relevant labour market variables. The...
This note, which forms part of a series of technical notes that complement Lastunen et al. (2021), reports the approach used to derive shocks to household expenditures from shocks at the individual-level labour incomes. Its structure is composed by...
This note sets out two different methods on how to adjust incomes in the microdata underlying the standard SOUTHMOD models to reflect a sudden shock, in this case the COVID-19 shock, as done in the accompanying working paper by Lastunen et al. (2021)...
This paper proposes a decomposition framework for quantifying contributions of the determinants of poverty to spatial differences or temporal changes in poverty. This framework is then applied to address the issue why poverty incidence is higher in...

This study investigates the ethnic disadvantage in rural Vietnam, focusing on the magnitude of the majority–minority gap and the constraints on ethnic minority households that contribute to the gap. Using a biannual panel dataset spanning the period...
A consensus among social scientists is that fertility rates in Africa are declining. What determines these declines? I present fresh evidence that shows education, especially for women, is an important determinant of the fertility transition in...
We exploit a spatial discontinuity in the coverage of an agricultural extension program in Uganda to causally identify its effects on malaria. We find that eligibility for the program reduced the incidence of malaria by 8.8 percentage points, with...
It is well known in theory that certain forms of non-linear dynamics in household incomes can yield poverty traps and distribution-dependent growth. The potential implications for policy are dramatic: effective social protection from transient...
This paper provides unique evidence of the positive consequences of seasonal migration for investments in early childhood development. We analyse migration in a poor shock-prone border region in rural Nicaragua where it offers one of the main...
This study explores the extent to which inequality affects the impact of income growth on the rates of poverty changes in sub-Saharan Africa (SSA) compared to non-SSA, based on an unbalanced panel of 86 countries over 1977–2004. For all three...
People in poor countries live shorter lives than people in rich countries so that, if we take income and health together, there is more inequality in the world than if we consider income alone. Yet international inequalities in life expectancy...
I discuss a new approach which decomposes inequality into the contributions of population groups by income sources. I estimate a matrix with rows and columns which indicate different population groups and income sources respectively, with each...
This paper relates Amartya Sen’s capability approach to the literature on equivalence scales. Synthetic indicators of well-being are constructed by adjusting individual incomes for differences in functionings. An exploratory comparative application...
Financial development can exert a significant influence on the distribution of income. In this paper, using Chinese provincial data over the period of 1991-2000 and applying the generalized method of moment (GMM) techniques, we investigate the...
This paper analyzes the evolution of poverty in China from the late 1980s to the late 1990s, employing a version of Shapley decomposition tailored to unit-record household survey data. The changes in poverty trends are attributed to two proximate...
Despite the growing interest in global inequality, assessing inequality trends is a major challenge because individual data on income or consumption is not often available. Nevertheless, the periodic release of certain summary statistics of the...

In this paper we address the issues involved with the use of microeconomic data, that is, household surveys, to compare the patterns of income growth among different regions instead of the commonly used aggregate data. In particular, we investigate...
The paper tests for external effects of local economic activity on consumption and income growth at the farm household level using panel data from four provinces of post-reform rural China. The tests allow for nonstationary fixed effects in the...
This paper examines the impact of income risk on the level of well-being of rural households in Nigeria. While income risk is defined as the risks associated with variability in income well-being is defined in terms of the level of utility reached by...
This paper tests using survey data from China whether individual health is associated with income and community-level income inequality. Although poor health and high inequality are key features of many developing countries, most of the earlier...

China’s recent accession to the WTO is expected to accelerate its integration into the world economy, which aggravates concerns over the impact of globalization on the already rising inter-regional income inequality in China. This paper discusses...
Using new household survey data for 1995 and 2002, we investigate the size of China’s urban-rural income gap, the gap’s contribution to overall inequality in China, and the factors underlying the gap. Our analysis improves on past estimates by using...
While the average level of income per capita has increased in China rapidly, income inequality is becoming a more serious problem that may threaten social stability and the sustainability of economic development. This paper examines the existence in...
This paper applies a new decomposition technique to the study of variations in poverty across the regions of Russia. The procedure, which is based on the Shapley value in cooperative game theory, allows the deviation in regional poverty levels from...
Studies of the inter-recipient allocation of aid may be categorized threefold. First, there are those which attempt to explain the observed allocation of aid. Second, there are those which seek to describe or evaluate the allocation of aid against...
Absolute poverty lines are often derived from the cost of obtaining sufficient calories. Where staples vary across regions, such poverty lines may differ depending on whether they are set using national or regional food baskets. Regional poverty...
A subjective well-being approach is followed to assess the magnitude of inefficiency in the use of income. The information comes from a Mexican survey and an X-inefficiency technique is used. The paper shows that there exists substantial inefficiency...
Inequality in Mexico rose between 1989 and 1994 and declined between 1994 and 2010. We examine the role of market forces (demand and supply of labour by skill), institutional factors (minimum wages and unionization rate), and public policy (cash...

A natural way of viewing an inequality or a poverty measure is in terms of the vector distance between an actual (empirical) distribution of incomes and some appropriately normative distribution (reflecting a perfectly equal distribution of incomes...
This paper reviews the evidence on the ‘inclusiveness’ of the growth in consumption expenditure that has occurred in India over the last four decades or so. The notion of dynamic inclusiveness is framed in terms of imagined normative allocations of...
The book aims to document and explain the sizeable decline of income inequality that has taken place in Latin America during the 2000s. It does so through an exploration of inequality changes in six representative countries, and ten policy chapters...
I present a model of intra-household allocation to show that when income is not perfectly observed by both spouses, hiding of income can occur even when revelation increases bargaining power. I draw data from Ghana and exploit the variation in the...
In this paper, we estimate the recent evolution of global interpersonal inequality and examine the effect of omitted top incomes on the level and direction of global inequality. We propose a methodology to estimate the truncation point of household...
