This paper investigates skills and the use of skills at work in 21 OECD countries. The skills included in the analysis are literacy, numeracy and problem-solving. The paper investigates the conjecture that the deterioration of skills with age might be more pronounced in occupations with a limited use of skills than in occupations with more intensive use of these skills - an implication of the ?use it or lose it? hypothesis. The paper examines the development over age of both measured skills and the use of skills at work in two aggregate categories of occupations: a group of high-skilled workers (ISCO major occupations from 0 to 4) and a group of low-skilled workers (ISCO major occupations from 5 to 9). High-skilled workers have higher measured skills than low-skilled workers and high-skilled workers use skills more at work than low-skilled workers. Measured skills decline from the age of 35 both for high- and low-skilled workers at about the same pace. The use of skills at work also declines from the age of 35 for both high-skilled workers and low-skilled workers at about the same pace, and at about the same rate as measured skills. The evidence does not support the ?use it or lose it? hypothesis. Este artículo investiga las habilidades y el uso de habilidades en el trabajo en 21 países de la OCDE. Las habilidades incluidas en el análisis son la escritura, el cálculo y la resolución de problemas. El trabajo investiga la hipótesis de que el deterioro de las habilidades con la edad podría ser más pronunciado en ocupaciones con un uso limitado de las competencias que en ocupaciones con un uso más intensivo de estas habilidades - una implicación de la hipótesis de "usarlo o perderlo". El documento analiza la evolución con la edad del nivel de las habilidades consideradas y el uso de las mismas en el trabajo en dos categorías agregadas de ocupaciones: un grupo de trabajadores altamente cualificados (ISCO principales ocupaciones de 0 a 4) y un grupo de trabajadores de baja calificación (ISCO principales ocupaciones de 5 a 9). Los trabajadores altamente cualificados tienen un nivel de habilidades más alto que los trabajadores poco cualificados y los trabajadores altamente cualificados utilizan más habilidades en el trabajo que los trabajadores poco cualificados. El nivel de habilidades disminuye a partir de los 35 años tanto para los trabajadores de alta y de baja cualificación al mismo ritmo. El uso de las habilidades en el trabajo también se reduce desde la edad de 35 años tanto para los trabajadores altamente cualificados y los trabajadores poco cualificados al mismo ritmo, y más o menos al mismo ritmo que el nivel de las mismas. La evidencia no apoya la hipótesis de "usarlo o perderlo".
