This paper studies monetary policy rules in a small open economy with Inflation Targeting, incomplete pass-through and rigid nominal wages. The paper shows that, when nominal wages are fully flexible and pass-through is low to moderate, the monetary authority should target the consumer price index (CPI) rather than the Domestic Price Index (DPI). When pass-through is high, an economy with high degrees of nominal wage rigidity and wage indexation should either target the CPI or fully stabilize nominal wages. The results of the paper suggest that, by committing to a common monetary policy in a common-currency area, some countries may not be following the right monetary policy rules.
