A Tale of a Tool
评估了克里斯托弗·西姆斯的向量自回归模型在新古典革命争议背景下对当代宏观计量经济学演化的影响，发现其使用并非全有或全无，而是工具、理论和研究者互动学习的结果。
This article assesses the impact of Christopher Sims’s VARs upon the evolution of contemporary macroeconometrics within the contentious context of the new classical revolution. We argue that the decision of using VARs was not an all-or-nothing affair, but the outcome of the evolving interaction of tools, theories, and researchers, within an overall process of learning by modifying. Using citation and cocitation networks, extracting algorithms and semantic networks, we found evidence that confirms the unfolding of an interdependent and collective evolution of the impact of Sims’s VARs, and the emergence of new groupings of most cocited articles at the interface of macroeconometrics and monetary policy analysis, revealing how the practice of macroeconometrics changed in the interim.
