Regras monetárias e dinâmica macroeconômica no Brasil: uma abordagem de expectativas racionais

Neste artigo estimamos e simulamos um modelo macroeconômico aberto de expectativas racionais (Batini e Haldane [4]) para a economia brasileira, com o objetivo de identificar as características das regras monetárias ótimas e a dinâmica de curto prazo gerada por elas. Trabalhamos com uma versão forward-Iooking e uma versão backward-Iooking a fim de comparar o desempenho de três parametrizações de regras monetárias, que diferem em relação à variável de inflação: a tradicional regra de Taylor, que se baseia na inflação passada; uma regra que combina inflação e taxa de câmbio real (ver Ball [5]) e uma regra que utiliza previsões de inflação (ver Bank af England [3]). Resolvemos o modelo numericamente e contruímos fronteiras eficientes em relação às variâncias do produto e da infiação por simulações estocásticas, para choques i.i.d. ou correlacionados. Os conjuntos de regras ótimas para as duas versões são qualitativamente distintos. Devido à incerteza quanto ao grau de forward-Iookingness sugerimos a escolha das regras pela soma das funções objetivos nas duas versões. Concluímos que as regras escolhidas com base neste critério têm perdas moderadas em relação às regras ótimas, mas previnem perdas maiores que resultariam da escolha da regra com base na versão errada. Finalmente calculamos funções de resposta a impulso dos dois modelos para algumas regras selecionadas, a fim de avaliar como diferentes regras monetárias alteram a dinâmica de curto prazo dos dois modelos.
