This paper examines the functional relationships between income inequality, economic factors, institutions, and Kuznets' inverted-U hypothesis. A model that incorporates interactive as well as direct effects of several factors to capture their combined effect on inequality is developed. The...

Income differences arise from many sources. While some kinds of inequality, caused by effort differences, might be associated with faster economic growth, other kinds, arising from unequal opportunities for investment, might be detrimental to economic progress. We construct two new metadata...

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...

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...

Using the Standardized World Income Inequality Database, we examine if the KOF Index of Globalization and the Economic Freedom Index of the Fraser institute are related to within- country income inequality using panel data covering around 80 countries 1970-2005. Freedom to trade internationally...

In this paper we compute inequality measures over the distribution of a subjective well-being variable constructed from a life satisfaction question included in the Gallup World Poll in almost all countries in the world. We argue that inequality in subjective well-being may be a better proxy for...

This paper presents the global income distribution between all individuals living in the developed world. Global inequality for the group of high-income countries, as measured by the Gini coefficient, stands at 37 in 2013 and has increased by almost 3 Gini points since the mid-1990s. This was...

We compare four methodologies to estimate the global distribution of income and find that many methods work well, but the method based on two-parameter distributions is more accurate than other methods. This method is simpler, easier to implement and relies on a more internationally-comparable...
