Global inequalities 1980-2050: a microdata oriented simulation – Worldsim

Former global inequality models lack realistic features of the population (age, gender,
education, behavior). Worldsim develops a panel sample based simulation of the world
population until 2050, relying on UN, Cepii, etc, big data aggregated forecasts, that we
individually disaggregate. The simulation confirms the decline of the world's Gini index,
but underlines several paradoxes in the socioecodemography of the world, with increasing
gaps between resources and needs. Compared to more standard socioeconomic
simulations of inequalities, we provide more substantial characterization of the population,
and compared to other global simulations, we capture the dimensions of social
divergences between social groups and geographic regions.
