O trabalho não visa avaliar ou julgar modelos, mas sim utilizar os mesmos como um suporte na avaliação da comparação preditiva. Desse modo procuramos avaliar e/ou comparar se os desvios entre as projeções de mercado e os indicadores efetivamente realizados são melhores do que os desvios entre um modelo econométrico e os mesmos indicadores efetivamente realizados. De um modo geral veremos que a pesquisa Focus do Banco Central do Brasil tem um poder preditivo satisfatória para todos os índices, se comparado com as previsões obtidas através dos modelos econométricos em estudo. / This work aim to compare the predictions obtained through the database of Research Focus from Central Bank of Brazil for the expectations of market exchange rates, interest rates and inflation. The paper does not intend to assess or judge models but use them as a support in the evaluation of the predictive comparison. Thus we evaluate and / or compare whether the deviations between market expectations and the indicators actually realized are better than the deviations between an econometric model and the same indicator actually realized. Generally we will see that the database of Research Focus from Central Bank of Brazil had a satisfactory predictive power for all indexes, compared with forecasts obtained from the econometric models in this study.
