Una de las características de los datos de renta procedentes de las Encuestas de Presupuestos Familiares es su escasa fiabilidad, ya que los hogares entrevistados ocultan parte de ella. Recientemente, Pena, Callealta, Casas, Merediz y Núñez (1996) han propuesto una metodología para corregir este problema de ocultación, que ha permitido generar una nueva serie de datos de renta. En este trabajo, estudiamos las repercusiones que tiene la utilización de la serie de renta original y la corregida para el año 1990-91 sobre la desigualdad. En concreto, contrastamos el dominio en sentido de la curva de Lorenz entre las distribuciones generadas por ambas series, siguiendo la metodología de la inferencia estadística paramétrica. The lack of accurate is a relevant feature of income data from the “Encuesta de Presupuestos Familiares“ because the interviewed households do not declare their true income. Recently, Pena, Callealta, Casas, Merediz y Núñez (1996) have generated a new set of data by mean of methodology that tries to correct this problem of hidden income . Throughout this paper, we study the consequences on income inequality of using the original set of data and the correct one. Concretely, we test the Lorenz dominance between the income distribution generated by both sets of data follow a parametric statistical inference approach.
