Wars or politic hostility between nations can lead consumers to modify their behavior, reducing consumption of goods made in hostile countries. In particular, events concerning the Second Intifada (2000) can be related to the decreasing sales of Arab goods occurred in recent years. This phenomenon can be explained through animosity, defined as "the remnants of antipathy related to previous or ongoing military, political or economic events towards current or former enemies" (Shoham et al. 2007, p.93). This paper has the aim to analyze antecedents and effects of animosity of Jewish-Italian consumers towards Arab products and comparing results obtained in the study of Shoham et al. (2006) in Israel with those obtained in Italy, considering also the role of their personality traits. A nine-section questionnaire, containing different scales, was administered to a sample of Jewish-Italian consumers (i.e., "Jews of the Diaspora"). In spite of their animosity towards Arab goods, they are not dogmatic and buy these products, if these are perceived as being of high quality. This is a result of their utilitarian personality, measured by the Big Five Factors and Utilitarianism/Hedoism high-order meta-traits. In presence of strong animosity, companies have to accurately consider entry strategies, product strategy and communication strategy in foreign markets. This is the first study considering animosity of Jewish-Italian consumers, one of the most ancient Jewish communities. Furthermore, it is the first analysis which considers simultaneously animosity and consumers' personality traits, showing the interesting result that utilitarian personality trait prevails on animosity attitude.
