QUIET: Search data reveals Russian household inflation views
A new Central Bank of Russia study introduces QUIET, an indicator of household inflation expectations for Russia and its regions, derived from search engine data. The indicator aims to complement traditional survey-based measures with timely, high-frequency information.
Building the QUIET indicator
The Central Bank of Russia's new research paper introduces QUIET, a novel indicator designed to measure household inflation expectations across Russia and its regions using search engine data.
The methodology involves identifying key search query topics related to inflation dynamics and expectations, then constructing a composite monthly and weekly indicator using the principal components method.
The study demonstrates that QUIET possesses high descriptive power in models assessing price dynamics and significantly reduces short-term forecast errors for the consumer price index (CPI).
It also offers advantages for nowcasting due to its rapid update capability.
The indicator's performance is compared against traditional survey-based measures, such as the inFOM household inflation expectations index and the CBR's business price expectations.
Beyond traditional surveys
Traditional inflation expectation surveys face challenges like high costs, slow updates during economic shocks, and potential respondent misinterpretation due to varying financial literacy.
Issues such as rounding, social desirability bias, and sample selection bias can also distort results.
The paper argues that search engine data offers an effective alternative, providing real-time, high-frequency information with significantly lower acquisition costs.
Users self-provide data, bypassing interpretation issues, and the online format enhances anonymity, reducing social desirability bias compared to traditional survey methods.
A timely policy complement
This study provides compelling evidence that search engine data offers a robust and timely complement to traditional inflation expectation surveys.
By addressing inherent limitations of survey methods, the QUIET indicator enhances the toolkit for understanding household sentiment in real-time.
Such data-driven insights are crucial for central banks aiming to improve forecasting accuracy and the effectiveness of monetary policy.
