Is more exchange rate intervention necessary in small open economies? The role of risk premium and commodity shocks

Author

Abstract

We estimate how the monetary policy works in small open economies with inflation target. To do so, we build a dynamic stochastic general equilibrium model that incorporates the basic features of these economies. We conclude that the monetary policy in a group of representative small open economies (including Australia, Chile, Colombia, Peru and New Zealand) presents strong differences due to shocks from the international financial markets (risk premium shocks, mainly) that explain mostly the variability of the real exchange rate, which has important reallocation effects in the short run. By using the allocations of the Ramsey problem as benchmark, this article shows that if the central banks in small open economies want to reduce the observed volatility of the inflation rate and the output gap, more exchange rate intervention is necessary in order to reduce the volatility produced by risk premium shocks.
