Credibility and the credit channel transmission of monetary policy theoretical model and econometric analysis for Brazil

摘要

Purpose - The purpose of this paper is to present a theoretical model and empirically verifies the transmission of monetary policy through the credit channel in Brazil. The study verifies if the monetary policy, the economic activity and the maturity of the inflation targeting regime affect the supply of credit. Design/methodology/approach - The paper offers a review of the literature concerning inflation targeting credibility and the transmission mechanism of monetary policy through the credit channel, it develops a theoretical model based on Bernanke and Blinder and Ferreira and it seeks empirical evidence for the Brazilian economy using ordinary least squares, generalized method of moments and vector autoregressive. Findings - The estimates indicate that the supply of credit is stimulated when the economy heats up, when the monetary authority reduces the interest rate and when the credibility increases. The evidence also indicate that the supply of credit is affected by the variables of the model, economic activity and employment are affected by monetary policy and the supply of credit exerts influence on both employment and output gap. Research limitations/implications - An important implication of this study is that, in inflation targeting emerging economies, such as that of Brazil, following a committed monetary policy to price stability which increases the credibility of the regime of inflation targeting and promoting macroeconomic stability represents a good strategy for improving the volume of lending to the private sector, thus stimulating economic activity and employment. What the findings do indicate is that developing credibility is crucial for emerging economies that are trying to grow, but with inflation being kept under control. Originality/value - The paper presents the following theoretical and empirical contributions: the model incorporates the effect that the credibility of the inflation targeting regime has on the supply of credit and, the econometric approach provides evidence that the monetary policy, the economic activity and the process of anchoring of inflation expectations affect the supply of credit in Brazil. Moreover, the paper finds evidence that the credit channel acts as a transmission mechanism of monetary policy to the economy.
