NEUTRAL TECHNOLOGY SHOCKS AND THE DYNAMICS OF LABOR INPUT: RESULTS FROM AN AGNOSTIC IDENTIFICATION*
研究中性技术冲击对劳动投入的动态影响，使用包含搜索与匹配摩擦的DSGE模型和基于符号约束的SVAR识别方法，发现劳动投入会随中性技术冲击而增加。
This article studies the dynamic response of labor input to neutral technology shocks. It uses benchmark dynamic, stochastic, general equilibrium models enriched with labor market search and matching frictions and investment‐specific technological progress that enables a new, agnostic, identification scheme based on sign restrictions on a structural vector autoregression (SVAR). The estimation supports an increase of labor input in response to neutral technology shocks. This finding is robust across different perturbations of the SVAR model.
