Inflation and Attention Thresholds
研究了38个国家中公众对通货膨胀的关注是否存在阈值，发现多数国家在通胀率2-4%时关注度显著上升，且这一现象在报纸报道中也存在。
Abstract One of the dangers of high inflation is that it can cause individuals to pay close attention to it. This internalization of inflation can lead to an accelerationist regime, making inflation harder to control. We empirically assess the relationship between attention and inflation for 38 countries. Our measures of attention are constructed from internet search behavior or the popularity of inflation mentions on Twitter. We find evidence that attention thresholds exist for most of the countries and that they typically occur between 2-4% inflation. We also document interesting variability across countries and find similar thresholds in newspaper coverage of inflation.
