Cross-Sectional Inflation Asymmetries and Core Inflation: A Comment on Bryan and Cecchetti
使用对Bryan和Cecchetti批评稳健的统计方法重新检验核心通胀与横截面通胀不对称性的关系,发现仅在月度频率上存在显著正相关,并指出抽样问题凸显了蒙特卡洛分析的重要性。
This paper reexamines the evidence relating core inflation to cross-sectional inflation asymmetry using statistical measures that are robust to the criticism of Bryan and Cecchetti. The results here suggest that there does exist significant positive correlation between core inflation and cross-sectional inflation asymmetry, but only at the monthly frequency. Furthermore, a sampling problem is highlighted which underscores the importance of careful Monte Carlo analysis when exact small-sample distributions are unknown.
