DMR-BR: um modelo aplicável de equilíbrio geral utilizado para análise dos efeitos de políticas econômicas no Brasil

Abstract

This paper presents the DMR-BR model constructed for the Brazilian economy. This is an Applied General Equilibrium Model, based on the Dervis, Melo and Robinson model built in 1982 to analyze the impact of economic policies in developing countries. The choice of the 15 sectors in Brazilian model was done using the concept of key-sectors. The input-output data base refers to the year of 1994, while the coefficients and parameters were either estimated or obtained from the literature. The simulations were conducted using Gempack, version 5.1, the solutions are giving in growth rates. As this model uses the Johansen approach, the linearization errors were corrected through the use of the Gragg method with the interpolation of the results from two, four and six steps. The results show that DMR-BR model presents a great potential in helping the planning process as well as in the analysis and implementation of the Brazilian economic policies.
