RESUMEN: En este trabajo se analiza el patrón estacional de la exportación semanal de tomate canario desde el ingreso de España en la Unión Europea. Un primer examen de los componentes determinísticos de la serie revela la inestabilidad de éstos, claramente vinculada a los cambios en la normativa comercial de acceso a los mercados europeos, así como la presencia de numerosas observaciones anómalas causadas por fenómenos de diversa índole. Estas circunstancias afectan al estudio detallado de la estacionalidad estocástica de la serie bajo estudio, que reúne dos características —la frecuencia semanal de las observaciones y la existencia de períodos sin exportación— cuya consideración es imprescindible para recoger apropiadamente la conducta de las exportaciones y, concretamente, la naturaleza del comportamiento estacional de las mismas. SUMMARY: This paper studies the evolution of the weekly exports of Canary Island tomatoes after the entry of Spain in the European Union. A first analysis of deterministic components reveals their instability, clearly related to changes in the EU commercial regulations of access to European markets, and the presence of many outliers due to different reasons. These factors must be considered in the study of stochastic seasonality of the series. Furthermore, it is necessary to take into account the weekly frequency data and the existence of periods without exports in order to capture its behaviour and, in particular, the nature of its seasonal component.
