Human Capital and Regional Wage Gaps

López-Bazo E. and Motellón E. Human capital and regional wage gaps, Regional Studies. This paper uses micro-level data to analyse the effect of human capital on regional wage differentials. The results for the set of Spanish regions confirm that they differ in the endowment of human capital, but also that the return that individuals obtain from it varies sharply across regions. Regional heterogeneity in returns is especially intense in the case of education, particularly when considering its effect on the employability of individuals. These differences in endowment and, especially, in returns to human capital account for a significant proportion of regional wage gaps. López-Bazo E. and Motellón E. 人力资本及区域工资差距,区域研究。本文利用微观数据分析了人力资本对于区域工资差异的影响。西班牙区域研究结果证明了人力资源禀赋方面存在的差异,同时个体回报率也存在巨大的区域差异。回报率的区域异质性在教育领域表现尤为明显,特别在考虑其对个体就业率的影响时。秉赋上的差异尤其是人力资本回报率差异构成了区域工资的显著差异。 教育 经验 区域差异 人力资本回 报率 工资差异分解 López-Bazo E. et Motellón E. Le capital humain et les écarts des salaires régionaux, Regional Studies. Cet article emploie des microdonnées afin d'analyser l'impact du capital humain sur les écarts des salaires régionaux. Les résultats pour l'ensemble des régions espagnoles confirment qu'elles diffèrent par la dotation du capital humain, mais aussi que le rendement qu'en obtiennent les individus varie sensiblement suivant la région. L'hétérogénéité régionale des rendements s'avère particulièrement vive pour ce qui est de l'éducation, notamment quand on tient compte de ses effets sur l'employabilité des individus. Ces différences de la dotation et, surtout, du rendement du capital humain expliquent une proportion non-négligeable des écarts des salaires régionaux.

Humankapital und regionale Einkommensunterschiede, Regional Studies. In diesem Beitrag wird mit Hilfe von Daten auf Mikroebene die Auswirkung von Humankapital auf regionale Einkommensunterschiede untersucht. Die Ergebnisse für die untersuchten spanischen Regionen bestätigen, dass sich die Regionen hinsichtlich der Ausstattung mit Humankapital, aber auch hinsichtlich der von den Personen dafür erzielten Erträge untereinander drastisch unterscheiden. Im Bildungsbereich fällt die regionale Heterogenität der Erträge besonders stark aus, vor allem wenn man ihre Auswirkung auf die Beschäftigungschancen der Personen berücksichtigt. Auf diese Unterschiede bei der Ausstattung und insbesondere bei den Erträgen des Humankapitals lässt sich ein erheblicher Anteil der regionalen Einkommensunterschiede zurückführen.

Capital humano y diferencias salariales por regiones, Regional Studies. En este artículo utilizamos datos a nivel micro para analizar el efecto del capital humano en las diferencias salariales por regiones. Los resultados para el grupo de las regiones españolas confirman que existen diferencias en cuanto a la dotación de capital humano, pero también varían en gran medida los beneficios que las personas obtienen a partir de este capital en las diferentes regiones. La heterogeneidad regional de los beneficios es especialmente aguda en el caso de la educación, en concreto cuando se considera qué efecto tiene para la capacidad de inserción laboral de las personas. Estas diferencias en las dotaciones y, especialmente, en los beneficios del capital humano representan un porcentaje significativo de las diferencias salariales por regiones.
