The study analyzes the behavior of the Brazilian’s beef exports, in natura, during the 1995 to 2003 period. It shows that the substantial increase in exports made the country one of the leading beef exporters and tries to identify the factors that contributed for this growth. The methodological procedures involve the application of the Constant-Market-Share model to identify the sources of growth of the exports through the world trade growth effect, origin of exports effect and competitive effect. The composition effect was not estimated given the fact that the model was applied to only one product. The results show that the competitive and structural effects gave a significant increase to the Brazilian’s exports. The study shows, also, that Brazil increased its market share due the several factors that contributed to an expansion in its exports through new world markets.
