This paper demonstrates that the property of 'replication invariance', generally considered to be an innocuous requirement for the extension of fixed-population poverty comparisons to variable-population contexts, is incompatible with other plausible variable- and fixed-population axioms. --...

What is the relationship between inequality and growth? This question has occupied and fascinated social scientists for more than a century. This article critically reviews the recent empirical and theoretical literature on the complex interplay between inequality and economic growth. Inequality...

In this paper, we convey the concept of first-order dominance (FOD) with particular focus on applications to multidimensional population welfare comparisons. We give an account of the fundamental equivalent definitions of FOD, illustrated with simple numerical examples. An implementable method...

This paper undertakes an assessment of the evolution of inequality in the distribution of consumption expenditure in India over the last quarter-century, from 1983 to 2009-10, employing data available in the quinquennial 'thick' surveys of the National Sample Survey Office. We find that...

Using illustrations from research on inequality, this paper offers evidence on the strengths of 'behavioural synthesis', i.e. the reconciliation between neoclassical and behavioural economics. We compare how theoretical models of absolute and relative inequality have evolved from assumptions of...

African populations need better support through social protection mechanisms. Among those who need social security are millions of older people who, having worked all their lives in the formal sector, are in precarious situations with lower benefits. This study aims to appreciate theoretically,...

This paper undertakes an empirical analysis of the adoption of various components of social security systems as well as contribution rates. Apart from economic determinants of the adoption, the empirical analysis features determinants relating to countries' political systems and contagion. We...

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 interest in the level of global inequality has surged in recent years. This paper complements existing estimates of global inequality by providing the first estimates of the level of bipolarization of the global income distribution. During 1975-2010, global bipolarization declined...

This paper develops a new imputation methodology applied to missing incomes values in PNAD. PNAD is the main Brazilian household survey, but it has no imputation. The imputation process starts by fitting regression models applied to different income sources considering the complex sampling...
