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...

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...

Over the past two decades, research on the impacts of a diverse range of public policies and income inequality has seen rapid growth. Despite the large number of publications to date, there remain important lacunae in our understanding of how policy interventions might help to reduce income...

This note revisits the ideas of the so-called semiparametric methods that we consider to be very useful when applying machine learning in insurance. To this aim, we first recall the main essence of semiparametrics like the mixing of global and local estimation and the combining of explicit...

Grouped data in the form of income shares have conventionally been used to estimate income inequality due to the lack of individual records. We provide guidance on the choice between parametric and nonparametric methods and its estimation, for which we develop the GB2group R package. We present...

A major of focus of global development policy is the aim to achieve and sustain income growth of the bottom 40% (B40) of the population at a rate higher than the national average. We propose an alternative approach to assessing shared prosperity using 'inequality lines'. Analogous to poverty...

This paper reviews the evidence on the effectiveness of active labour market programmes in low- and middle-income countries with high informality, highlighting examples of interventions that have been implemented in combination with other policies including social protection measures. In...

This study conducts an international comparative analysis of the recent evolution of social protection systems in sub-Saharan Africa (SSA), Latin America and the Caribbean (LAC), and Asia-Pacific (APAC) regions, paying particular attention to the role of foreign aid in these dynamics. It asks:...

In recent years, randomized controlled trials have become increasingly popular in the social sciences. In development economics in particular, their use has attracted considerable debate in relation to the identification of 'what works' in development policy. This paper focuses on a core topic...

This paper examines the impacts of the financial, food and fuel crises on the livelihoods of low-income households Nigeria. It uses primary household level data from Nigeria to analyse the impacts of induced price variability on household welfare. Our results indicate that aggregate shocks have...
