Resumen

The European tomato market is characterised by a constant process of dynamicadjustment toward the equilibrium. Furthermore, Canary tomato exports cause a highseasonal impact on market prices in the winter period. In these circumstances, an adequatedistribution of shipments throughout the campaign could contribute to maximize producers’profits.The goal of this paper is to analyse the seasonal pattern of Canary tomato exports toEurope throughout the first fourteen campaigns following Spanish integration into theEuropean Union. These export levels show some degree of instability, clearly related to thechanges in the European Union trade rules, and there is a long period, the summer, withoutexports. Moreover, we have opted by using weekly data. These factors should be taken intoaccount in order to accurately capture the performance of exports and, specifically, thenature of their seasonal behaviour. Thus, this analysis is carried out inside the framedelimited by the structural approach to time series and the usefulness of spline functions asan alternative to standard seasonal variation models is shown.
