No. of bitstreams: 1 TESE_ODILON.pdf: 885119 bytes, checksum: 460d85982ff9b027e21ee9ef445337e1 (MD5) Previous issue date: 2013-09-20 / Several attempts of negotiation of future contracts and price indexes of beef cattle in Argentina and in Uruguay were frustrated along the years. The derivatives issued failed in a short period of time due to lack of liquidity. That scenery and other particularities of the live cattle spot market turned the administration of risk of prices into a problem for the economical agents of the meat chain. In this context, the following question emerged: the cross hedging with future contracts of Brazilian live cattle in the Brazilian Securities, Commodities and Futures Exchange (BM&FBovespa) is effective for the administration of risk of prices of beef steers in the Argentinian and Uruguayan spot market? In an effort to answer this question, it was proposed to verify if it is possible to mitigate the risk of the price volatility of the spot market of Argentinian and Uruguayan beef steers through of cross hedging in the futures market for Brazilian live cattle in the BM&FBovespa. For this, it was used static and dynamic models to estimate of the optimal cross hedge ratio and effectiveness of risk mitigation. The results of the hypothesis test of risk mitigating allow to assure that there are strong empirical evidences of effectiveness of the futures market of Brazilian live cattle in protection against the prices risk of the spot market of Argentinian and Uruguayan steers. Complementarily, it was analyzed the hypothesis of the futures market efficiency. The results present empirical evidence of a stochastic relationship common in long-term between spot and futures prices, and efficiency in predicting short-term price, which suggest that the future contracts of Brazilian live cattle in the BM&FBovespa allow adequate hedge of price for the Argentinian and Uruguayan steers in spot market. / Na Argentina e no Uruguai, diversas tentativas de negociação de contratos futuros e de índice de preços de carne bovina foram frustradas ao longo dos anos, tendo os derivativos lançados fracassado, em um curto espaço de tempo, por falta de liquidez. Esse cenário, somado a outras particularidades do mercado físico da carne bovina, torna o gerenciamento de risco de preços um problema para os agentes econômicos que atuam nessa cadeia produtiva. Nesse contexto, emergiu a seguinte questão: a proteção cruzada com contratos futuros de boi gordo brasileiro da Bolsa de Valores, Mercadorias e Futuros de São Paulo (BM&FBovespa) é efetiva para a administração do risco de preços dos novilhos de corte no mercado a vista argentino e uruguaio? Com a finalidade de responder a essa questão, propôs-se a verificar se é possível mitigar o risco da volatilidade de preços no mercado a vista dos novilhos de corte argentinos e uruguaios por meio do cross hedging no mercado futuro do boi gordo brasileiro na BM&FBovespa. Para tanto, foram utilizados modelos estáticos e dinâmicos de estimação da razão de cross hedge ótima e efetividade em mitigação do risco. Os resultados do teste de hipóteses de mitigação do risco permitiram assegurar que são fortes as evidências de efetividade do mercado futuro do boi gordo brasileiro na proteção contra o risco de preços do mercado a vista dos novilhos argentinos e uruguaios. Complementarmente, verificou-se a hipótese de eficiência do mercado futuro. Os resultados apresentaram evidências de um relacionamento estocástico comum no longo prazo entre os preços a vista e futuros, e de eficiência na predição dos preços no curto prazo, o que sugere que os contratos futuros de boi gordo brasileiro da BM&FBovespa permitem uma trava adequada de cotação-preço para os novilhos argentinos e uruguaios no mercado a vista.
