Fifth meeting of the Society for the Study of Economic Inequality (ECINEQ)




The Fifth Meeting of the Society for the Study of Economic Inequality (ECINEQ) will be held at the University of Bari (Italy) from July 22 to July 24, 2013.

The ECINEQ conference provides a forum for a rigorous analysis of inequality, welfare and redistribution issues, both at the theoretical and at the empirical level, as well as for a discussion of the policy implications of the research findings in this field.

ECINEQ aims at achieving high scholarly standards in both the selection of topics and their debates, whether they concern theoretical issues, empirical analyses or the implementation of policies.

We model the evolution of age-dependent personal money income distribution and income 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 the individual income growth with age. The model relates the evolution of personal income to the  individual’s capability to earn money, the size of her work instrument, her work experience and aggregate output growth. Our model is calibrated to the single-year population cohorts as well as the personal incomes data in 10-and 5- year age bins provided by the Census Bureau. We predict the dynamics of personal incomes for every single person in the working-age population in the USA between 1930 and 2011. The model output is then aggregated to construct annual age-dependent and overall personal income distributions (PID) and to compute the Gini ratios. The latter are predicted very accurately - up to 3 decimal places. We show that Gini for people with income is  approximately constant since 1930, which is confirmed empirically. Because of the increasing proportion of people with income between 1947 and 1999, the overall Gini reveals a tendency to decline slightly with time. The age-dependent Gini ratios have different trends. For example, the group between 55 and 64 years of age does not demonstrate any decline in the Gini ratio since 2000. In the youngest age group (from 15 to 24 years), however, the level of income inequality increases with time. We also find that in the latter cohort the average income decreases relatively to the age group with the highest mean income. Consequently, each year it is becoming progressively harder for young people to earn a proportional share of the overall income.
