Economic transparency and effectiveness of monetary policy

Purpose The purpose of this paper is to study if the central bank (BC) communications affect the effectiveness of the monetary policy. Design/methodology/approach For this analysis, a new Keynesian theoretical model and the ordinary least squared methodology were used. The objective to be achieved was to determine if there is some effect of economic transparency on accountability, inflation average, output gap, interest and central bank credibility. Findings The results highlighted that central banks with greater transparency contribute to decrease inflation rate and interest rate. The findings denote that an increase in the information quality (clarity) implies a significant change in the rate of readjustment of market expectations. Furthermore, central bank transparency contributes to anchor the public expectations and to affect long‐run interest rates. Research limitations/implications Impulse‐answer research was employed to show how the central bank transparency affects the credibility of monetary authorities. Practical implications This paper suggests that the central bank publicizes its outlook, its policy monetary decisions, its expectations and its preferences. Originality/value The originality of the paper resides in the fact that empirical and theoretical studies were made in the single work. Also, new results were found denoting that economic transparency reduces uncertainty effect and increases the power of incentive contract made between the BC and public.
