This paper studies the demand for international tourism in the Mediterranean Region. The Introduction is mainly devoted to a review of the most important attempts to model econometrically the demand for international tourism in the past. In Section II, the formal presentation of the theoretical model is given. In particular, a version of the Almost Ideal Demand System (AIDS) is adopted. Description of the variables involved and their sources, together with the estimation procedure, are analysed in Section III. The performed diagrammatic analysis contributes to a better understanding of the evolution of the dependent variable over time. Section IV presents and critically evaluates the empirical findings. In particular, the results with respect to the expenditure as well as to the own- and cross- price elasticities may be regarded as econometrically satisfactory and a reasonable economic explanation may be given. The paper concludes by providing a summary of the main findings and discussing possible extensions for future work in the field.
