Résumé

L'utilité pratique des approches non monétaires de la pauvreté est interrogée sur base de l'étude du degré de recoupement entre mesures directes et mesure monétaire de ce concept. L'utilisation de la méthode graphique de la courbe du Receiver Operating Characteristic (ROC) permet, contrairement à l'approche généralement utilisée, d'évaluer ce degré de recoupement indépendamment du seuil de privation utilisé. L'application de cette méthode aux données du Panel Communautaire des Ménages confirme l'aboutissement de nombreux travaux, à savoir que les résultats issus de ces deux approches se recoupent, mais de manière imparfaite. Dès lors, c'est le caractère complémentaire, plutôt que celui substituable de ces deux mesures qui prévaut. Un tel résultat plaide donc pour un approfondissement de la recherche sur les méthodes directes de mesure de la pauvreté, et ce en vue de compléter l'approche monétaire largement utilisée.

Summary

Summary

The practical utility of the non monetary approaches of poverty is assessed on the basis of the study of the overlap between income and direct outcome measures of poverty. The use of the graphic method of the curve of the Receiver Operating Characteristics allows, contrary to the approach traditionally used, to assess the degree of overlap independently of the threshold of deprivation. The application of this methodology to the data of the European Community Household Panel shows a significant discrepancy between these approaches, hence advocating for a complementary, rather than substitutable, use of these approaches and for further research on the methods of measurement of multidimensional poverty.
