Abstract

English Abstract: We study the effect of time-varying disagreement among professional forecasters on the transmission of monetary policy in Korea, which has transitioned from an emerging to an advanced economy. We find that high levels of disagreement interfere with the transmission of monetary policy and, hence, weaken monetary policy effects. However, under low levels of disagreement, a monetary policy shock elicits textbook-like responses of inflation, expected inflation, and real activity. The findings are consistent with the view that disagreement affects the role of the signalling channel of monetary transmission relative to the conventional transmission channel. We also show that the dependence of the transmission on the level of disagreement remains intact even after controlling for time-varying monetary policy uncertainty and considering the shifts in the Bank of Korea’s inflation target type.

Korean Abstract: 본 연구는 기대인플레이션 불일치 정도가 통화정책 파급효과에 미치는 영향을 한국 데이터를 이용하여 실증분석하였다. 전문가 기대인플레이션의 산포도로 측정된 기대인플레이션 불일치에 따른 통화정책 효과의 변화를 상태의존 국소투영모형(state-dependent local projection model)을 이용하여 분석하였다. 분석 결과 기대인플레이션의 불일치 정도가 높은 상태에서 긴축적 통화정책 충격은 인플레이션을 유의하게 낮추지 못하였으며, 성장률 전망치 등 실물지표는 단기적으로 이론과 반대되는 움직임을 보였다. 반면 불일치 정도가 낮은 상태에서는 긴축적 통화정책 충격이 인플레이션을 낮추고 실물경기를 둔화 시키는 전통적인 결과가 도출되었다. 또한 이러한 결과는 통화정책에 대한 불확실성 지표, 물가안정 목표치의 형태 변화, 성장률 및 단기금리 전망치에 대한 고려 여부 등에 관계없이 강건하게 유지되는 것으로 나타났다.
