PRICE TRANSMISSION ON THE MILK PORTUGUESE MARKET

This paper aims to analyze the milk prices transmission along the food chain in Portugal, temporally and spatially. The results show that the volatility on retail prices is small but happens after 2008. The farm gate price does not change when the price of package milk changes. In mainland, price transmission does not happen but for Azores the transmission is effective. In the intensive systems, the risk to collapse is bigger than in the extensive systems, where the volatility of prices reflects the process of markets adjustment.
