宏觀經(jīng)濟(jì)學(xué)家越來(lái)越多地使用外生變異的外部來(lái)源進(jìn)行因果推斷。然而,除非這些外部工具(代理)捕捉到潛在的沖擊而沒(méi)有測(cè)量誤差,否則現(xiàn)有的方法對(duì)這種沖擊對(duì)宏觀經(jīng)濟(jì)波動(dòng)的重要性保持沉默。我們證明,在具有外部工具的一般移動(dòng)平均模型中,工具沖擊的方差分解是區(qū)間識(shí)別的,具有信息的界。各種附加限制保證了方差和歷史分解的點(diǎn)識(shí)別。與SVAR分析不同,我們的方法不需要可逆性。應(yīng)用于美國(guó)數(shù)據(jù),它們給出了貨幣沖擊對(duì)通脹動(dòng)態(tài)重要性的嚴(yán)格上限。

英文摘要:
Macroeconomists increasingly use external sources of exogenous variation for causal inference. However, unless such external instruments (proxies) capture the underlying shock without measurement error, existing methods are silent on the importance of that shock for macroeconomic fluctuations. We show that, in a general moving average model with external instruments, variance decompositions for the instrumented shock are interval-identified, with informative bounds. Various additional restrictions guarantee point identification of both variance and historical decompositions. Unlike SVAR analysis, our methods do not require invertibility. Applied to U.S. data, they give a tight upper bound on the importance of monetary shocks for inflation dynamics.
