On the Relationship between Inflation Persistence and Temporal Aggregation
研究时间聚合（从月度到季度再到年度）如何影响通胀持久性的不同定义，基于美国CPI和核心PCE平减指数发现时间聚合会引入通胀序列的持久性。
This paper examines the impact of temporal aggregation on alternative definitions of inflation persistence. Using the CPI and the core PCE deflator of the United States, our results show that temporal aggregation from the monthly to the quarterly to the annual frequency induces persistence in the inflation series.
