The Gini coefficient features prominently in Amartya Sen's 1973 and 1997 seminal work on income inequality and social welfare. We construct the Gini coefficient from socialpsychological building blocks, reformulating it as a ratio between a measure of social stress and aggregate income. We...

The merger of populations expands the comparison space of incomes. As a result, measures of the income-based social stress and of the income inequality of the constituent populations need to be replaced by new measures. To this end, we develop a procedure for calculating the aggregate social...

Following Sen's (1973) characterization of the Gini coefficient as a ratio between a measure of aggregate income-based stress ("depression" in Sen's terminology) and aggregate income, we transform the Gini coefficient into a social welfare function rather than having the Gini coefficient feature...

We examine an assumed link between reducing inequality in income distribution, namely reducing the Gini coefficient on one hand, and improving public health in general and lowering the incidence and severity of COVID-19 in particular on the other hand. The Gini coefficient can be shown to...

We provide an analytical-behavioral explanation for the observed positive relationship between income inequality, as measured by the Gini coefficient, and the incentive to migrate. We show that a higher total relative deprivation of a population leads to a stronger incentive to engage in...
