Foreign output shocks, monetary rules and macroeconomic volatilities in small open economies

The 2008 financial crisis is marked by the drop in output of major industrial countries which affected small open economies in various degrees. We examine the role of three different types of monetary policy rules in mitigating or exacerbating the effects of a negative foreign output shock on key macroeconomic variables of a small open economy by numerically solving a dynamic stochastic general equilibrium (DSGE) model. We find that compared to the Taylor rule, small open economies that follow either fixed exchange rate regime or strict inflation targeting tend to stabilize real exchange rate and inflation at the expense of substantial instability in the real economy.
