This working paper examines the sacrifice ratio, i.e., the percentage cost of actual production lost to every one percentage point decrease in (trend) inflation, for selected Southeast Asian economies. Results indicate that upon adopting a contractive monetary policy, GDP growth dropped by up to 0.5%, confirming that monetary authorities’ disinflationary policies typically trigger declines in both output and employment. However, as even minor adjustments to the way of determining the sacrifice ratio lead to varying results, caution ought to be applied when deriving potential (monetary) policy recommendations.
