Price effects of commodity financialization: Review of the evidence
这篇综述梳理了2007/2008年金融危机后关于商品金融化价格效应的实证研究，发现统计方法的选择会影响结论，且金融化的定义仍模糊不清。
Abstract Following the 2007/2008 financial crisis, the price effects of commodity financialization have become an important research topic. We review the empirical evidence, focusing on statistical approaches and econometric models, and find that (1) Granger‐causality tests are unable to establish a relationship between commodity futures prices and funds of financial investors, implying a lack of evidence that financialization influences commodity futures prices and (2) studies that use correlation and price spread analysis mostly report evidence of a significant price effect of financialization. Thus, the statistical and econometric approaches adopted by the various studies influence the empirical findings. In addition, data identification may have an impact since economic models and statistical techniques can be sensitive to slight differences in the dataset. Our study of the literature shows that the definition of financialization is open‐ended and ambiguous. A theoretical literature review on financialization could be the logical next step.
