The study analyses trends in global income distribution since 1950 using a new companion WIID dataset with standardized country income percentiles. It investigate the robustness of these trends with respect to key data choices, as well as the degree to which the inequality trend depends on specific...

– Ghana case study
Over the years, money-metric measures of inequality such as the Gini coefficient and the Palma Ratio, as frequently used in Ghana, have become useful in providing quantitative measures of welfare distribution that enable a better understanding of the extent and nature of inequality. From these...

In this paper we explore the links between international migration and income inequality. After presenting a simple model which considers the role of income distribution in individual decisions to migrate, we estimate a set of models on the determinants of yearly bilateral migration from a very...

– The role of different parts of the income distribution
In this paper we reassess the relationship between inequality and human development, focusing on the differential effect associated with the concentration of national income at different parts of the income distribution. To do so, we rely on a large global panel of countries over the last decades...

I discuss the applicability of the recentered influence function (RIF) to the analysis of poverty differentials between distributions (regression-based decomposition into composition and income structure effects). I show that the predominant approach in the empirical literature estimates the...

We revisit trends in within-country income inequality using a newly integrated dataset that covers at least 70 per cent of the global population since 1980. We investigate absolute and relative inequality trends across the past four decades, combining the use of Lorenz curves with a set of...

This paper presents preliminary evidence of the annual global income distribution since 1950 using a new integrated dataset that aggregates standardized country income distributions at the percentile level estimated from various sources in the World Income Inequality Database. I analyse the extent...
Income inequality is the result of complex processes with multiple interacting driving forces but understanding those drivers in emerging economies is particularly difficult because of data and analytical challenges. While most middle-income countries produce comprehensive household surveys these...

Working Paper
pdf
Notwithstanding the unprecedented attention devoted to reducing poverty and fostering human development via scaling up social sector spending, there is surprisingly little rigorous empirical work on the question of whether social spending is effective in achieving these goals. This paper examines...
Position Paper
pdf
This position paper on Aid and the Social Sectors was prepared by UNU-WIDER under the ReCom programme of Research (Re) and Communication (Com) on foreign aid. It aims to provide a coherent up-todate overview and analysis of an extraordinarily important issue in the development field: The contribution of foreign aid to human development.Social sector policy and the services that they provide are recognised for their intrinsic values and instrumental qualities for the functioning of individuals in particular, and the development strategies of countries more general. There is overwhelming...

While the majority of interventions against HIV/AIDS, tuberculosis, and malaria had positive short-term effects, these were frequently not translated into long-term sustainable results. Cash transfers may have the potential of reducing HIV transmissions but the effect is so far insignificant...
Research Brief

Microfinance evaluations reveal a positive impact on per capita income, non-land asset value and poverty incidence. Across countries and methodologies, microfinance is most likely to have a short-term positive effect; regionally, the most positive impacts are seen in Africa. Women tend to benefit...

– Implementation of the New Aid Effectiveness Agenda in Health and Education in Zambia
There is a growing interest in the debate on aid effectiveness for assessing the impact of aid not only on economic growth and poverty reduction, but also on intermediate outcomes such as health and education. This paper reviews evidence from recent in-depth country work on the impact of government...

– Crucial for the Spread of Social Protection Programmes
Evaluations of social protection programmes have been much more comprehensive in Latin America than in sub-Saharan Africa. Monitoring and evaluation protocols are crucial to facilitate improvements in government effectiveness. Anti-poverty transfer schemes seem to be subjected to more evaluation...

– Why Does Aid Not Address Poverty (Much)?
Aid is not generally aimed at the poorest people, though most multilateral or bilateral agencies would like to think they get included. However, donors’ strategies are generally blind to differentiation among the poor, and have not improved in this respect. The special provisions for the least...
