中文摘要
本文介绍RESET示范项目的初步成果, 该项目利用单品层面交易数据构建价格与销售指数。项目的总体目标是通过指向一个以21世纪数据与技术重建官方经济统计的未来, 展示利用现代交易数据进行经济测量的可行性与优势。本文提出了家庭食品的若干新通胀测量指标, 并从两个方面对其加以评估: 一是与现行官方统计相比表现如何; 二是作为能够更准确刻画消费者选择动态的新型指标, 它们能提供哪些增量信息。本文还讨论了利用单品层面交易数据生产可靠且可信的官方统计所面临的挑战, 并报告了关于近期家庭食品通胀趋势的研究发现。
Abstract
ABSTRACT This paper presents early results from the RESET Demonstration Project, an initiative that constructs price and sales indices using item-level transactions data. The project’s overarching goal is to demonstrate the feasibility and advantages of leveraging modern transactions data for economic measurement by pointing toward a future in which official economic statistics are rebuilt on 21st-century data and technology. The paper introduces new inflation measures for Food at Home and evaluates them on two fronts: how they compare to current official statistics and what they offer as novel measures that capture more accurately the dynamics of consumer choice. The paper also addresses the challenges of producing reliable and credible official statistics from item-level transactions data and reports findings on recent Food at Home inflation trends.
