This study investigates the impact of Left political institutions on a nation's amount of poverty. Specifically, the analysis tests three possible causal relationships: whether Left political institutions affect poverty separately from the welfare state, channeled through the welfare state, or...

We investigate the properties of a family of social evaluation functions and inequality indices which merge the features of the family of Atkinson (1970) and S-Gini (Donaldson and Weymark (1980, 1983), Yitzhaki (1983) and Kakwani (1980)) indices. Income inequality aversion is captured by...

Income inequality has risen sharply in the United States over the past generation, reaching levels not seen since before World War II. But while almost two-thirds of Americans agree with the statement that 'income differences in the United States are too large', policies aimed at reducing income...

Across OECD countries there are large differences in the average level and trend of working hours and there is persuasive evidence that attitudes to paid employment, particularly for women, differ significantly. This paper therefore asks the question: 'How much of the difference between...

This paper examines whether retirement-income systems allow older individuals to enjoy socially acceptable income levels independent of paid work (decommodification) and the family (defamilialization). Little research has investigated the degree to which decommodification and defamilialization...

The Luxembourg Income Study data is used to explore the impact of taxes and transfer payments on the distribution of income across thirteen countries for different years. The five-parameter generalized beta distribution and ten of its special cases are considered as models for the size...

Whenever a country experiences an increase in its mean income, inequality roars its ugly head and the net outcome in terms of poverty remains ambiguous. Kakwani (2000) proposes an instrument that allows quantifying this inequality-growth tradeoff. This paper applies that methodology to 28...

Income and expenditure surveys typically provide data on the household level, and household types may differ in needs. In order to make the standard measures of inequality and welfare applicable to such a heterogeneous population, researchers transform it into an artificial quasi-homogeneous...
