A common critique of most measures of income inequality, which are based on a single year's income, is that they fail to take account of income mobility. If income fluctuations are large, and individuals can smooth consumption, then high inequality and high mobility may be no worse than low...

In a number of high-income countries over the past few decades there has been a large growth in income inequality and at the same time a shift in the burden of taxation from the top to the middle of the income distribution. This paper applies the theory of optimal piecewise linear taxation to...

The available empirical evidence indicates that the distribution of private income in Australia is polarising. While there are a number of factors underlying this trend, it is clear that the dramatic swing to "economic rationalist" policies since the mid 1980s has been a major cause of the...

In recent years, researchers have used taxation statistics to estimate the share of total income held by the richest groups, such as the top 10% or the top 1%. Compiling a standardised top income shares dataset for thirteen developed countries, I find that there is a strong and significant...

This study examines changes in earnings inequality for full-time employees in Australia between 1982 and 1994-95 using individual-level data from the ABS Income Distribution Survey. It present measures of changes in earnings inequality for disaggregated workforce groups. It also provides...

Do income taxes levied at a state or regional level affect the after-tax distribution of income? Or do workers merely move between regions, causing pre-tax wages to adjust? This question is relevant both in across states in the United States, and across countries within the European Union. Using...

Societies typically have three objectives for work and welfare: sustained income/economic growth per capita, employment growth (and job security?), a just distribution of income along with access to certain basic services. There may be tensions between these objectives. This paper tries to...

Prior to the last three decades, regular surveys on household income were rare or non-existent in many developed countries, making it difficult for economists to develop long-run series on income distribution. Using taxation statistics, which tend to be available over a longer time span, I...

Pooling data for 1905 to 2000, we find no systematic relationship between top income shares and economic growth in a panel of 12 developed nations observed for between 22 and 85 years. After 1960, however, a one percentage point rise in the top decile’s income share is associated with a...

This paper studies the changes in earnings inequality. It also examines the causes and consequences of this changes.
