O Vale do S?o Francisco, ao longo dos anos, vem se destacando como a principal regi?o produtora de frutas do pa?s, especialmente de manga e de uva. A manga, produzida nessa regi?o, tem alcan?ado uma boa inser??o internacional, principalmente, nos mercados europeu e americano. Entretanto, o pre?o interno tem absorvido cada vez mais o impacto das oscila??es do mercado internacional afetando as expectativas de produ??o e comercializa??o dos produtores. O objetivo do estudo ? analisar a rela??o de transmiss?o dos pre?os de exporta??o da manga, com os pre?os do mercado americano e da Uni?o Europeia, no per?odo entre 2003 a 2013. Pretende-se, ainda, analisar os fatores que afetaram as flutua??es das exporta??es da manga brasileira para os principais mercados importadores. Para alcan?ar os objetivos propostos, empregouse, na metodologia, o modelo vetorial autoregressivo, com a finalidade de se constatar os mecanismos de transmiss?o de pre?os e os mecanismos de impactos por meio da fun??o impulso resposta. Utilizou-se, ainda, o modelo Constant Market Share, com o objetivo de se observar a import?ncia dos efeitos competitividade, destino, e crescimento do com?rcio mundial sobre as mudan?as das exporta??es brasileiras de manga, no per?odo em an?lise. Os dados utilizados foram obtidos no database do Minist?rio de Desenvolvimento e Com?rcio Exterior - MIDIC e do FAOSTAT (Food and Agriculture Organization of the United Nations). Entre os resultados encontrados, constatou-se, que os pre?os do mercado interno brasileiro sofrem influ?ncia dos pre?os do mercado americano, e que choques de pre?os promovidos nesse mercado podem repercutir no crescimento dos pre?os internos por v?rios meses. Notou-se ainda, que o efeito competitividade representou a maior parcela do crescimento efetivo das exporta??es brasileira, ou seja, o pa?s melhorou sua competitividade dentre os demais pa?ses exportadores. / Climate and environmental conditions allowed Brazil to become one of the largest producers of tropical fruits in the world. The S?o Francisco Valley, over the years, has emerged as the main fruit-producing region of the country, especially mangos and grapes. The mango, which is produced in this region, has reached a good international position, especially in European and American markets. However, the domestic price has absorbed more and more the impact of fluctuations in the international market expectations affecting the production and marketing of producers. The objective of the study is to analyze the transmission ratio of export prices of the mango, with the American market prices and the European Union in the period from 2003 to 2013. It is intended also to analyze the factors affecting the fluctuations of exports Brazilian mango for the main import markets. To achieve the proposed objectives, we used, in the methodology, the autoregressive vector model, in order to find the price transmission mechanism and the mechanisms of impacts through the impulse response function. We also used, the Constant Market Share model, in order to observe the importance of the effects competitiveness, destination, and growth in world trade on the changes of Brazilian mango exports in the period. The data used were obtained from the database of the Ministry of Development and Foreign Trade - MIDIC and FAOSTAT (Food and Agriculture Organization of the United Nations). Among the results, it was found that the Brazilian domestic prices are influenced by the US market price, and that price shocks promoted this market can impact on the growth of the internal prices for several months. It was noted also that the competitiveness effect accounted for the largest portion of the effective growth of Brazilian exports, in other word, the country has improved its competitiveness among the other exporting countries.
