Este estudo estima uma curva de Phillips com mudança de regime para a economia brasileira no período 1995-2008. De maneira geral, são três os principais resultados encontrados: i) ao contrário do que ocorreu nos resultados anteriores, ao adotarem-se especificações não lineares para a curva de Phillips, o coeficiente da expectativa de inflação torna-se superior ao coeficiente da inflação passada. Isto sugere que artigos que estimam a curva de Phillips por modelos lineares podem estar subestimando o papel das expectativas na dinâmica inflacionária; ii) os testes sugerem fortemente a rejeição da hipótese de linearidade nos parâmetros da curva de Phillips, isto é, a estimação da curva de Phillips por métodos lineares seria viesada e ineficiente; e iii) os resultados econométricos mostram pouca robustez, e alta sensibilidade, dos parâmetros a diferenças nas especificações de não linearidade ou mudanças no conjunto de proxies adotadas. Isto parece indicar a inadequação da curva de Phillips para explicar a dinâmica inflacionária na economia brasileira.
