I fattori determinanti dell'export di vino secondo il modello gravitazionale: un'applicazione alle principali destinazioni mondiali

International wine trade has gained a great importance during years, specially for our country, and there’s a raising interest in the study of its structure, functioning and the forces that govern it. In this work international wine export has been studied with a gravity model - an econometrical model with an increasing importance and acceptance among scientist - for the explication of transactional phenomenal. The study concerned bilateral trade of twelve of the main wine markets, both importers and exporters, from 1997 until 2010, utilizing a proper panel data for still and sparkling wine. According to previous works found in literature regarding gravity wines, in addition to the classical model estimation, it has been proposed an expanded model in order to obtain more accurate results. This expanded model include more variables than those traditionally included in literature (distance and GDP) like exchange rate and wine production of exporting country, language and trade barriers. The hypothesis that lead to variables election is tied to them growing importance in the economic policy intervention at international level, in particular in the market regulation of good and inside the WTO. In practice, the aim was to evaluate if these variables have a great impact also in the case of wine market. Results leads to believe that wine export are strongly conditioned by the income level of the importing country, while distance, even having a negative impact, doesn’t seem to have the same importance found in another goods. When countries have the same official language the model show a trade growth of more than twice, and also exporter exchange rate has a significant effect, with an increasing export when exporter currency devaluate. In order to better evaluate the role of trade barriers, that has growing relevance for alimentary goods and especially for wine, tariff and non tariff barriers have been taken into account. In addition, non tariff barriers have been divided into technical barriers and sanitary – ...
