The majority of the world's poor, by income poverty and multi-dimensional poverty, now live in countries officially classified by the World Bank as middle-income countries. Of course nothing happens when a country crosses a (somewhat) arbitrary threshold in per capita income but it does matter...

This paper discusses the emergence of two new middles since the Cold War, namely middle-income countries and people living above absolute poverty but below a security-from poverty-line. The paper sets out what has happened. It is argued that although there has been substantial economic growth,...

This paper discusses the 'developer's dilemma' - a tension emerging from the fact that developing countries are simultaneously seeking structural transformation and broad-based growth to raise incomes of the poor. Simon Kuznets originally hypothesized that structural transformation may have a...

In this paper, we present new projections for a range of global poverty-related Sustainable Development Goals (SDGs), specifically, extreme monetary poverty, undernutrition, stunting, child mortality, maternal mortality, and access to clean water and basic sanitation. Our projections, based on...

This paper begins by noting that Uganda has been a public sector reform leader in Africa. It has pursued reforms actively and consistently for three decades now, and has produced many laws, processes and structures that are 'best in class' in Africa (and beyond). The problem is that many of the...

In this paper we argue that the decline in global inequality over the last decades has spurred a 'sunshine' narrative of falling global inequality that has been rather oversold, in the sense, we argue, it is likely to be temporary. We argue the decline in global inequality will reverse due to...

This paper provides a broad picture of national, regional and global trends of inequality in length of life over the period 1950-2015. We use data on life tables from World Population Prospects to develop a comprehensive database of a battery of inequality measures for 201 countries at five-year...

This paper presents the first global and regional estimates of polarization and bipolarization spanning the period 1960-2020. The study relies on group data to implement a flexible parametric model to obtain the global income distribution and polarization estimates. The study introduces a...

Monitoring health is key for identifying priorities in public health planning and improving healthcare services. Life expectancy has conventionally been regarded as a valuable indicator to compare the health status of different populations. However, this measure is simply the mean of the...

Governments can play great roles in their countries, regions, and cities; facilitating or leading the resolution of festering problems and opening new pathways for progress. Examples are more numerous than one might imagine and raise an important question: 'how do governments become great?'....
