The study attempts to determine the CACM, MERCOSUR and NAFTA competitive position in the agri-food market taking into account selected indicators related to GDP, productivity and trade. The analysis allowed to state that only for MERCOSUR the competitive position in global food-market improved. In that groupings, compared to NAFTA and CACM, there was a bigger increase in GDP per capita and labour productivity in agriculture. Furthermore, only the share of MERCOSUR agri-food trade in world trade increased which was accompanied by a greater increase of extra-regional agri-food trade than intra-regional ones.
