I consumi domestici del vino in Italia: un modello a regressione quantile sulla domanda di vino siciliano

In the past decade or so, Sicilian wines have managedto gain market margins, both in quantitative andqualitative terms. This paper assesses extrinsic andintrinsic attributes of the Sicilian wine1, providingan explicit measure of the appreciation of Italianconsumers. The methodology used is based uponan hedonic price model. From an empirical point ofview, hedonic price estimation can be cumbersomewhen at price ranges correspond quality informationto consumers. The proposed model takes properlyinto account market price segmentation andquality differentiation by performing a quantileregression estimation. The empirical model isbuilt on the Sicilian wines marketed in year 2010in Italy. Transactions sales of 6.600 households,statistically representative of Italian population,were recorded by A.C Nielsen. Results show thatbasic Sicilian wines are particularly appreciated inSicily while premium and super-premium Sicilianwines gain higher prices in extra-regional markets.
