主席致辞:货币政策重要吗?叙事方法35年后的进展

Presidential Address: Does Monetary Policy Matter? The Narrative Approach after 35 Years
American Economic Review · 2023 · Christina Romer、David Romer

中文摘要

宏观经济识别的叙事方法使用定性来源(如报纸或政府记录),以提供有助于确立因果关系的信息。本文以关于货币政策影响的新研究为核心应用,讨论了严谨叙事分析的要求。我们阅读了美联储政策制定会议的历史纪要和记录,以识别1946年至2016年间并非为应对当前或预期的实际经济活动发展而采取的重大紧缩性和扩张性货币政策变动。我们发现,此类货币冲击在预期方向上对失业率、产出和通货膨胀具有巨大且统计显著的影响。对可用政策记录的分析表明,2022年很可能发生了一次紧缩性货币冲击。基于对以往冲击影响的实证估计,人们会预期2023年和2024年实际GDP和通货膨胀将受到重大负面影响。

Abstract

The narrative approach to macroeconomic identification uses qualitative sources, such as newspapers or government records, to provide information that can help establish causal relationships. This paper discusses the requirements for rigorous narrative analysis using fresh research on the impact of monetary policy as the focal application. We read the historical Minutes and Transcripts of Federal Reserve policymaking meetings to identify significant contractionary and expansionary changes in monetary policy not taken in response to current or prospective developments in real activity for the period 1946 to 2016. We find that such monetary shocks have large and significant effects on unemployment, output, and inflation in the expected directions. Analysis of available policy records suggests that a contractionary monetary shock likely occurred in 2022. Based on the empirical estimates of the effect of previous shocks, one would expect substantial negative impacts on real GDP and inflation in 2023 and 2024. (JEL E31, E52, E58, E65, N12)
