Abstract: The presence of asymmetric vertical price contagions in the Italian pork market is investigated, describing the multiple dependence structure along the supply chain and evaluating the degree of extreme value dependence at different market levels. We provide a nonlinear copula-based Vector AutoRegressive (VAR) model built under a three stage estimation method. We contribute to the literature, providing a specification of the copula-based Impulse Response Functions (IRF), giving also an interpretation of the economic results to the empirical analysis.
