This paper will analyze the interdependence between monetary and fiscal policies in Brazil, considering the concept of bounded rationality. The central problem addressed is the impact of expectations about the future on the behavior of intertemporal discounting in the present. To this end, this paper will use Bayesian estimations of a New-Keynesian DSGE macroeconomic model, with quarterly data spanning from 1999 to 2023, and will compare the results between the rational and behavioral approaches. The underlying hypothesis is that the behavioral approach of the proposed model is more in line with the traditional expected behavior of Brazilian monetary and fiscal policies compared to the rational approach, and suggests the presence of evidence of fiscal dominance in the Brazilian economy. The specific objectives include estimating different intertemporal discount parameters for the rational and behavioral approaches, evaluating the behavior of monetary and fiscal policies when there is limitation or leniency regarding the time horizon of economic agents' expectations, and investigating possible evidence of fiscal dominance in the Brazilian economy. This paper aims to contribute to a better understanding of the dynamics of economic policies in the context of bounded rationality, providing relevant advances for the formulation of public policies and opening new perspectives for the analysis of the interaction between monetary and fiscal policies in Brazil.
