South Africa is considering introducing carbon taxes to reduce greenhouse gas emissions. We evaluate potential impacts using a dynamic economy-wide model linked to an energy sector model. Simulation results indicate that a phased-in carbon tax that reaches US$30 per ton of CO2 by 2022 achieves...

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...

This study represents the first attempt at an integrated approach to assessing the potential impacts of climate change on the national economy of South Africa via a number of (but not necessarily all) impact channels. The study focuses on outcomes by about 2050. The results show the multiple...

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?'....

'Leadership' is not a common topic for research in international development. In recent years, however, prominent studies like the 2008 Growth Commission Report noted the importance of leadership in development. This and other studies focused on individual leaders - or heroes - when examining...
