Resumen de Improving small area estimation by combining surveys: new perspectvives in regional statistics

Alex Costa, Albert Satorra Brucart, Eva Ventura Colera

• A national survey designed for estimating a specific population quantity is sometimes used for estimation of this quantity also for a small area, such as a province.

  Budget constraints do not allow a greater sample size for the small area, and so other means of improving estimation have to be devised. We investigate such methods and assess them by a Monte Carlo study. We explore how a complementary survey can be exploited in small area estimation. We use the context of the Spanish Labour Force Survey (EPA) and the Barometer in Spain for our study.
