This paper points to flaws in Gini decompositions by income sources and population subgroups and to common pitfalls in the interpretation of decomposition results, focusing on methods within the framework of Rao (1969). We argue that within this framework Gini elasticities may provide the only...

Studying lifetime income inequality for individuals who belong to the same cohort can contribute valuable insights that cannot be obtained by usual analyses of annual incomes. Data from the social security system indicates that in West Germany, over the cohorts born between 1935 and 1972,...

This article uses recently released data from the Pesquisa Nacional por Amostra de Domicílios Contínua (PNAD Contínua), Brazilian household survey to calculate changes in inequality as measured by the Gini coefficient from 2016 to 2017. A Shorrocks decomposition by factor components is also...

This text was written as part of the project Modelling of Complex Systems for Public Policy. It reviews the classical authors who jointly contributed to establish the elements of what could constitute a "science of complexity". Based on the original writings of these authors, the text discusses...

In this article we examine how model selection in neural networks can be guided by statistical procedures such as hypotheses tests, information criteria and cross validation. The application of these methods in neural network models is discussed, paying attention especially to the identification...
