Inflation and Relative Price Variability: Reinstating Parks' Results
重新审视帕克斯关于通胀与相对价格波动时间序列关系的经典研究，发现考虑通胀正负阶段的不对称反应后，两者仍显著正相关，且该结论在排除石油冲击年份、延长样本期、使用替代数据集和更高细分程度下依然成立。
This paper revisits Parks' seminal work on the time series relationship between inflation and relative price variability. The results reported show that a significant positive association is obtained allowing for an asymmetrical response of relative prices to episodes of positive and negative inflation. This finding is maintained after excluding oil shock years, extending Park's original sample to 1996, using an alternative data set and allowing for a higher degree of disaggregation.
