Byrne J. P., Fazio G. and Piacentino D. Total factor productivity convergence among Italian regions: some evidence from panel unit root tests. Regional Studies. This paper employs panel unit root tests to investigate convergence in total factor productivity (TFP) among Italian regions. These tests provide an inference valid in the presence of heterogeneity and cross-sectional dependence, and when the cross-sectional dimension is smaller than the time dimension, allowing the investigation of convergence among different subsets of regions. The results add a further dimension to the conventional view on growth dynamics in the Italian peninsula depicting a lack of regional TFP convergence not only at the national level, but also at the level of geographical disaggregations where regions are conventionally thought to converge.

Convergence de la methode des facteurs globaux de productivite entre les regions italiennes: donnees probantes issues de tests de racine unitaire en panel. Regional Studies. Dans cet article, nous utilisons des tests de racine unitaire en panel pour etudier la convergence de la methode des facteurs globaux de productivite entre les regions italiennes. Ces tests nous fournissent une inference valide en presence d'une heterogeneite et d'une dependance transversale, et lorsque la dimension transversale est inferieure a la dimension temporelle, ce qui nous permet d'examiner la convergence entre les differents sous-ensembles de regions. Nos resultats ajoutent une dimension nouvelle a l'opinion classique sur la dynamique de croissance dans la peninsule italienne en decrivant une absence de convergence regionale de la methode des facteurs globaux de productivite non seulement au niveau national, mais egalement au niveau des ventilations geographiques, alors que l'idee conventionnelle veut que ces regions soient en train de converger.

Konvergenz der Gesamtfaktorproduktivitat unter italienischen Regionen: Belege anhand von Panel-Unit-Root-Tests. Regional Studies. In diesem Beitrag untersuchen wir mit Hilfe von Panel-Unit-Root-Tests die Konvergenz der Gesamtfaktorproduktivitat unter italienischen Regionen. Diese Tests ermoglichen einen gultigen Ruckschluss bei Prasenz von Heterogenitat und sektionsubergreifender Dependenz sowie in den Fallen, in denen die sektionsubergreifende Dimension kleiner ist als die Zeitdimension, so dass eine Untersuchung der Konvergenz in verschiedenen Untergruppen von Regionen moglich wird. Unsere Ergebnisse verleihen der konventionellen Betrachtung der Wachstumsdynamik auf der italienischen Halbinsel eine weitere Dimension, da sie eine mangelnde Konvergenz der Gesamtfaktorproduktivitat nicht nur auf nationaler Ebene, sondern auch auf der Ebene der geografischen Disaggregationen verdeutlichen, wo normalerweise von einer Konvergenz der Regionen ausgegangen wird.

Convergencia de la productividad total de los factores en regiones italianas: ejemplos de tests de raices unitarias con datos de panel. Regional Studies. En este articulo empleamos tests de raices unitarias con datos de panel para investigar la convergencia en la productividad total de los factores en las regiones italianas. Estos tests nos ofrecen una interferencia valida en presencia de heterogeneidad y dependencia transversal y si la dimension transversal es menor que la dimension del tiempo, podemos investigar la convergencia entre los diferentes subgrupos de regiones. Nuestros resultados anaden una dimension adicional a la imagen convencional sobre las dinamicas de crecimiento en la peninsula italiana representando una falta de convergencia regional en la productividad total de los factores no solo a nivel nacional sino tambien en los niveles de desagregacion geografica donde se supone tradicionalmente que las regiones se convergen.
