We model the evolution of age-dependent personal income distribution and inequality as expressed by the Gini ratio. In our framework, inequality is an emergent property of a theoretical model we develop for the dynamics of individual incomes. The model relates the evolution of personal income to...

We analyze and develop a quantitative model describing the evolution of personal income distribution (PID) for males and females in the U.S. between 1930 and 2014. The overall microeconomic model, which we introduced ten years ago, accurately predicts the change in mean income as a function of...

The evolution of personal income distribution (PID) in four countries: Canada, New Zealand, the UK, and the USA follows a unique trajectory. We have revealed precise match in the shape of two age-dependent features of the PID: mean income and the portion of people with the highest incomes (2 to...

The evolution of Gini coefficient for personal incomes in the USA between 1947 and 2005 is analyzed and modeled. There are several versions of personal income distribution (PID) provided by the US Census Bureau (US CB) for this period with various levels of resolution. Effectively, these PIDs...

This paper quantitatively demonstrates that modern estimates of income inequality based on the data reported by the IRS are not reliable. The principal problem of the estimates is highly volatile incomes of people in the low-end of income distribution. This volatility is likely related to...

We consider definitions and measuring procedures of personal income used by three U.S. agencies as well as the evolution of household size distribution and reveal major quantitative inconsistencies in the reported figures of personal and household inequality. The problem with the inequality...

Numerical modelling of the age-dependent personal income distribution (PID) in the USA is fulfilled based on a micro and macroeconomic model and results of the overall PID modelling. As expected from the age-dependent accuracy of the Current Population Surveys, the model has demonstrated an...

Income inequality between different races in the U.S. is especially large. This difference is even larger when gender is involved. In a complementary study, we have developed a dynamic micro-economic model accurately describing the evolution of male and female incomes since 1930. Here, we extend...

Numerical modelling of the personal income distribution (PID) in the USA from 1950 to 2003 is accomplished based on a microeconomic model for the personal income evolution. It is shown that the overall PID demonstrates the existence of some fixed hierarchical income distribution structure in the...

The personal income distribution (PID) above the Pareto threshold is studied and modeled. A microeconomic model is proposed to simulate the PID and its evolution below and above the Pareto income threshold. The model balances processes of income production and dissipation for any person above 15...
