Abstract: In this paper, we apply the methodology developed by Jenkins and Lambert (1996) to the study of the evolution ofpoverty in Spain during the 1980's. The main advantage of this approach lies in the fact that it provides poverty orderings consitent with a wide subset of generalized poverty gap poverty indices, while allowing different poverty lines for each of the distributions being compared. Our contnbution focuses on two aspects. (i) We estimate poverty trends for homogeneous subgroups of households of the same size. For the heterogeneous population as a whole, we study the robustness of our results to the choice of the equivalence scale. (ii) We extend to our procedures of statistical inference which are already used in the inequality literature. The main conclusion is the unambrigous fall in poverty levels, both in the population as a whole as well as in all subgroups in the partition by household siz.e.
En este trabajo utilizamos la metodologfa desarrollada por lenkins y Lambert (1996) para analizar la evoluci6n de la pobreza en Espafia durante la d6cada de los 80. La principal ventaja de este enfoque es que proporciona 6rdenes de pobreza consistentes con un amplio subconjunto de indices de pobreza del gap de pobreza generalizado, a la vez que permite la utilizaci6n de lineas de pobreza diferentes en cada una de las distribuciones que se pretenden comparar. Nuestra contribuci6n se centra en dos aspectos. (i) Estimamos los niveles de pobreza en subgrupos homogeneos constituidos por hogares con el mismo tamafio. En el caso de la poblaci6n total estudiamos la robustez de los resultados ante diferentes escalas de equivalencia. (ii) Extendemos a esta metodologfa los procedimientos de inferencia estadistica ya existentes en la literatura de desigualdad. La principal conclusi6n es el descenso unanime en los niveles de pobreza tanto en el conjunto de la poblaci6n como en todos los subgrupos de la partici6n por tamafio del hogar.
