Measurement Bias in the HICP: What do we know and What do we need to know?
回顾了欧元区调和消费者价格指数（HICP）测量误差的研究现状，指出由于概念框架模糊、研究不足和指数持续改进，目前缺乏科学依据来估计HICP的正向偏差。
Abstract. The Harmonized Index of Consumer Prices (HICP) is the primary measure of inflation in the euro area, and plays a central role in the policy deliberations of the European Central Bank (ECB). The ECB defines its Treaty mandate of price stability as ‘… a year‐on‐year increase in the Harmonised Index of Consumer Prices (HICP) for the euro area of below 2%[…] to be maintained over the medium term.’ Among the rationales given for defining price stability as prevailing at some positive measured inflation rate is the possibility that the HICP as published incorporates measurement errors of one sort or another that may cause it to systematically overstate the true rate of inflation in the euro area. This paper reviews what currently is known about the scope of measurement error in the HICP. We conclude that given the vague conceptual framework of the HICP, the scant research on price measurement issues in the EU and the ongoing improvements in the HICP, there is very little scientific basis at this time for a point (or even an interval) estimate of a positive bias in the HICP.
