Evaluation de «l’effet préférence» de la diaspora algérienne en France pour les produits de terroir

The purpose of this paper is to evaluate consumer preferences of the Algerian diaspora in France to Algerian local products. Many research shows that the consumers of Diaspora affect exports from their country of origin. The methodology mobilized consists to compare the import and export elasticities' obtained by the gravity model to deduce whether the preference effect is more or less high. Our focus is on a category (local product) of product that has not yet attracted the attention of researchers in international economics. It seems to us that these products need our attention, especially since they are getting increasingly importance in international trade. For example, they are on average of 31% of total agricultural / agro-food products exported by Algeria. At the methodological level, we use a questionnaire survey among the consumers of Algerian diaspora, to assess their preferences vis-à-vis the products of their country of origin. Our results showing a net preferences effect of Diaspora consumer for local products.
