Inflation Targeting and Relative Price Variability: What Difference Does Inflation Targeting Make?

This article studies the effects of inflation targeting (IT) on relative price variability (RPV) using a data set of twenty countries comprising both targeters and nontargeters. We find that a decline in mean inflation after IT adoption is not necessarily associated with a similar fall in RPV and that what matters most for the structural changes in RPV is the initial inflation regime prior to the adoption of IT rather than IT adoption itself. IT adoption impacts the shape of the underlying relationship between inflation and RPV in countries with initially high inflation rates, moving it from monotonic to the U‐shaped profile observed consistently for countries with low‐inflation regimes. The minimum point of this U‐shaped curve is indicative of the public's expectations of inflation and is very close to the announced target for inflation in most of the countries we study.     

Heterogeneous response of disaggregate inflation to monetary policy regime change: The role of price stickiness

This paper explores how a monetary regime change affects headline inflation via differential effects on various sectors in the economy. Using disaggregated CPI data for Canada, we find that the response to the adoption of inflation targeting (IT) was quite heterogeneous across sectors. While sticky-price sectors experienced a notable change in inflation dynamics following IT adoption, little structural change was observed in flexible price sectors. Our analysis based on a common factor model suggests that the structural changes in the sticky price sectors are driven by a decline in their responses to common aggregate shocks, including a monetary shock.

城市建成环境对鸟类多样性的影响 机制研究评述及展望

城市化带来的环境变化是生物多样性的主要威胁， 但城市同样也是生物多样性保护的热点地区。因此，分析和预 测城市环境变化对生物多样性的影响对于维护城市生态系统服 务，提升人类福祉至关重要。目前，越来越多的研究对城市建 成环境进行了详细的分类，分别量化了各个城市特征对生物多 样性水平的影响。然而，对影响城市内生物多样性水平的因 素仍缺乏多尺度、全球性的分析。借助Web of Science和 CNKI，对来自全球37个城市的111篇文献进行了建成环境下 鸟类多样性研究方法和结果的系统性分析，并在归纳关键性城 市建成环境要素的基础上，提出了以生物多样性为导向的建成 环境优化策略，指出了鸟类多样性保护和城市可持续发展的未 来方向。
