本文提出了一种为分类行业选择需求转移工具的新方法。我使用投入产出表中的先验信息来识别其产出波动可能对其他行业产生近似外生需求冲击的行业。在理论上激发了这个想法之后,我使用 1977 年详细的输入输出研究中的数据实现了输入输出方法。我对 450 多个美国制造业进行了系统的仪器搜索,发现 200 多个行业拥有合理的仪器。最后,我以一个简短的应用来说明如何使用投入产出工具来估计水泥行业的短期供给曲线。
This article proposes a new method of selecting demand-shift instruments for disaggregated industries. I use prior information from input-output tables to identify industries whose output fluctuations are likely to function as approximately exogenous demand shocks for other industries. After motivating this idea theoretically, I implement the input-output approach using data from the 1977 detailed input-output study. I conduct a systematic instrument search for over 450 U.S. manufacturing industries and find over 200 industries possessing plausible instruments. I conclude with a brief application, showing how input-output instruments can be used to estimate the short-run supply curve of the cement industry.
