Abstract

This paper studies the link between wage differences and individual earnings inequality for a sample of Spanish continuously working males from the European Community Household Panel for the period from 1994 to 1998. We analyse and quantify the contribution of two labour market features that could affect this link: the role of permanent and transitory wage inequality, and the existence of a significant response in individuals¿ hours of work to shifts in their own wage rates. Based on Hyslop (2001), we propose a particular specification for wages and earnings that incorporates an intertemporal labour supply model and we obtain predictions on wage and earnings inequality using a covariance structure framework. En este trabajo se analiza la relación entre las diferencias salariales y la desigualdad en rentas laborales individuales para una muestra de hombres empleados de forma continua en España en el período comprendido entre 1994 y 1998 procedente del Panel de Hogares de la Unión Europea (PHOGUE). En concreto, se analiza y cuantifica la contribución de dos aspectos del mercado laboral que pueden afectar a dicha relación o transmisión: el papel de la desigualdad salarial permanente o transitoria, y la existencia de respuestas significativas de las horas de trabajo de los individuos a variaciones en sus propios salarios. Basándonos en Hyslop (2001), se propone una especificación particular para los salarios y las rentas laborales que incorpora un modelo de oferta de trabajo intertemporal. A través de la estimación de dicho modelo, se obtienen predicciones de la desigualdad salarial y la desigualdad en rentas laborales utilizando un enfoque de estructura de covarianza.
