Abstract
Este documento describe los métodos de la tercera ola de la Encuesta Financiera de las Familias (EFF2008), prestando atención especial a los cambios introducidos respecto a las olas anteriores. La EFF2008 fue diseñada para dar continuidad a la información sobre finanzas de los hogares recogida a través de la EFF2002 y la EFF2005. Una característica deseable presente en las tres olas es el sobre muestreo de los hogares más ricos. Este sobre muestreo se consigue a partir del Impuesto del Patrimonio a través de un mecanismo de colaboración ciego entre el Instituto Nacional de Estadística y la Agencia Tributaria que respeta estrictos requisitos de confidencialidad. Una característica adicional importante de la EFF es que la segunda y la tercera ola tienen un componente de panel completo. Además, se ha incorporado una muestra de refresco por estratos de riqueza en esas dos olas para mantener la representatividad de corte transversal y el tamaño muestral total. La EFF es la única fuente estadística en España que permite relacionar las rentas, los activos, las deudas y el gasto de cada unidad familiar. La utilidad de la información recogida en una encuesta como la EFF ha llevado a la decisión por parte del sistema europeo de bancos centrales a realizar una encuesta de riqueza a los hogares en todos los países del área del euro siguiendo una metodología similar a la EFF. Por lo tanto, la EFF2008 permitirá comparaciones armonizadas con las nuevas encuestas de riqueza europeas
This paper describes the methods of the third wave of the Spanish Survey of Household Finances (EFF2008), paying special attention to the innovations relative to the previous waves. The EFF2008 was designed to give continuity to the information on household finances collected through the EFF2002 and the EFF2005. A desirable characteristic present in all three waves is the oversampling of wealthy households. This is achieved on the basis of the wealth tax through a blind system of collaboration between the National Statistics Institute and the Tax Office which preserves stringent tax confidentiality. An additional important characteristic of the EFF is that the second and third waves have a full panel component. Further, a refreshment sample by wealth stratum has been incorporated in those two waves to preserve cross-sectional representativity and overall sample size. The EFF is the only statistical source in Spain that allows the linking of incomes, assets, debts, and consumption at the household level. The usefulness of the information contained in a survey such as the EFF has led to the decision from the European system of central banks to conduct a household wealth survey in all euro area countries following a methodology similar to the EFF. Therefore, the EFF2008 will allow harmonized comparisons with the new European wealth surveys
