Frick J. R. and Goebel J. Regional income stratification in unified Germany using a Gini decomposition approach, Regional Studies. Using representative micro data from the German Socio-Economic Panel Study (SOEP), this paper delivers new insights into the development of income inequality and regional stratification in Germany after unification. This paper applies a new method for detecting social stratification by a decomposition of the Gini index that yields the obligatory between- and within-group components as well as an 'overlapping' index for the different sub-populations. It is found that East Germany is still a stratum on its own when using post-government income, but since 2001 no longer is when using pre-government income. These results remain stable when using alternatively defined regional classifications. However, there are also indications of some regional variation within West Germany. [image omitted] Frick J. R. et Goebel J. Les tranches de revenu regional dans l'Allemagne unifiee employant une decomposition Gini, Regional Studies. A partir des donnees microeconomiques provenant de la Socio-Economic Panel Study (SOEP - enquete permanente socio-economique) menee en Allemagne, cet article cherche a fournir de nouvelles perspectives sur le developpement des inegalites de salaire et des tranches de revenu regional en Allemagne au lendemain de l'unification. On applique une nouvelle methode qui permet de deceler les couches sociales par la decomposition de l'indice Gini qui fournit les necessairs elements intragroupe et intergroupe ainsi qu'une indice “chevauchante” pour les differentes sous-categories de la population. A partir de la dotation globale de fonctionnement, il s'avere que l'est de l'Allemagne reste toujours une couche a part entiere mais, depuis 2001, il ne l'est plus quand on considere les ressources propres. A partir d'autres classements regionaux, ces resultats restent inchanges. Cependant, il s'avere une certaine variation regionale dans l'est de l'Allemagne. Inegalite Decomposition Gini Tranches Unification allemande Ecarts regionaux SOEP Frick J. R. und Goebel J. Regionale Einkommeusstratifizietung im wiedervereinigten Deutschland mit Hilfe eines Gini-Dekompositionsansatzes, Regional Studies. Mit Hilfe reprasentativer Mikrodaten des soziookonomischen Panels fur Deutschland (SOEP) werden in diesem Beitrag neue Einblicke in das Entstehen eines Einkommensungleichgewichts und einer regionalen Stratifizierung in Deutschland nach der Wiedervereinigung geliefert. Wir nutzen eine neue Methode zur Erkennung von sozialer Stratifizierung mit Hilfe einer Dekomposition des GINI-Indexes, was zu den obligatorischen Komponenten zwischen und innerhalb von Gruppen sowie zu einem, uberlappunge-Index fur die verschiedenen Subpopulationen fuhrt. Nach unseren Ergebnissen stellt Ostdeutschland weiterhin eine eigenstandige Schicht dar, wenn man vom Einkommen unter Berucksichtigung aller staatlichen Transfers ('post-government income') ausgeht, hingegen seit 2001 nicht mehr, wenn man das Einkommen ohne diese Transfers ('pre-government income') untersucht. Diese Ergebnisse bleiben auch bei Verwendung unterschiedlich definierter regionaler Klassifikationen stabil. Allerdings gibt es auch innerhalb von Westdeutschland Anzeichen einer gewissen regionalen variation.

Estratificacion de ingresos regionales en la Alemania unificada usando un enfoque de descomposicion del indice Gini, Regional Studies. Con ayuda de micro datos representativos de un estudio de panel socioeconomico aleman, en este articulo aportamos nuevas perspectivas sobre el desarrollo de desigualdades de ingresos y estratificacion regional en Alemania tras la unificacion. Empleamos un nuevo metodo para detectar la estratificacion social mediante una descomposicion del indice GINI que produce los componentes obligatorios entre y dentro de los grupos asi como un indice de 'solapamiento' para las diferentes subpoblaciones. Al analizar los ingresos posgubernamentales observamos que Alemania del este es todavia un estrato en si pero deja de serlo a partir de 2001 si estudiamos los ingresos pregubernamentales. Estos resultados siguen siendo estables al utilizar clasificaciones regionales definidas de forma alternativa. Sin embargo, tambien hay indicios de cierta variacion regional dentro de Alemania del oeste.
