Widely used by economists in Brazil; the "Brazil Cost" concept refers to costs that hinder development, as they burden production, removing its competitive character, indispensable in a globalized economy. Brazil Cost may imply major obstacles to Foreign Direct Investment in the Country (FDI) and consequently impact the country's growth and development. The study evaluated the influence of variables that are part of the Brazil Cost in Foreign Direct Investment over the last six years. For this, the DMA-Dynamic Model Averaging methodology was used, which allowed the modeling of the dependent variable, FDI, as a function of its past and other variables dynamically over time. These results contribute to the evaluation of the assumptions made about the relationship between the components of Brazil Cost and the volume of direct investment in the country. Abstract-Widely used by economists in Brazil; the "Brazil Cost" concept refers to costs that hinder development, as they burden production, removing its competitive character, indispensable in a globalized economy. Brazil Cost may imply major obstacles to Foreign Direct Investment in the Country (FDI) and consequently impact the country's growth and development. The study evaluated the influence of variables that are part of the Brazil Cost in Foreign Direct Investment over the last six years. For this, the DMA-Dynamic Model Averaging methodology was used, which allowed the modeling of the dependent variable, FDI, as a function of its past and other variables dynamically over time. These results contribute to the evaluation of the assumptions made about the relationship between the components of Brazil Cost and the volume of direct investment in the country.

The Cost-Brazil can involve in a big obstacle to the Direct Investment in the Country (IDP) and the growth of the country. This cost is one of the main obstacles for the economic development of the country. This cost refers to rates that makes it difficult to the development and therefore burdens the competitive character that is indispensable in the global economy. The article did a study about the influence of the variable that makes up Cost-Brazil in the direct investment in the country through the last six years. The methodology DMA-Dynamic Model Averaging, that permitted the modeling of the dependent variable IDP in function of other variables in the dynamic form through the years. The found results contribute to verify the assumptions made regarding the components of cost-Brazil and the volume of the Direct Investment in the country.
