The Effectiveness of Unconventional Monetary Policy at the Zero Lower Bound: A Cross‐Country Analysis
利用八个发达经济体的月度数据，通过面板向量自回归模型评估非常规货币政策对经济活动和消费者价格的短期影响，发现其效果与传统货币政策相似但价格影响较弱。
This paper assesses the macroeconomic effects of unconventional monetary policies by estimating a panel vector autoregression (VAR) with monthly data from eight advanced economies over a sample spanning the period since the onset of the global financial crisis. It finds that an exogenous increase in central bank balance sheets at the zero lower bound leads to a temporary rise in economic activity and consumer prices. The estimated output effects turn out to be qualitatively similar to the ones found in the literature on the effects of conventional monetary policy, while the impact on the price level is weaker and less persistent. Individual country results suggest that there are no major differences in the macroeconomic effects of unconventional monetary policies across countries, despite the heterogeneity of the measures that were taken.
