Os efeitos da transparência e da clareza do Banco Central do Brasil sobre a volatilidade das taxas de juros de longo prazo

Abstract

This paper aims to study the effects of economic transparency and the clarity of the Central Bank of Brazil on the volatility of long - term interest rates. For this purpose, the term structure of the interest rate was included in a new-keynesian model of open economy and with government. The results of the models with clarity and transparent BCB emphasize the fall in the volatility of these rates, since the monetary authority published information on the future of the basic interest rate. Moreover, in models with clarity, monetary policy shocks have smoother and longer-term effects on future interest rates, indicating the dominance of the forward guidance (BCB’s clarity) tool in determining these rates.
