Price Changes in the Euro Area and the United States: Some Facts from Individual Consumer Price Data
利用欧元区多国商店层面的月度价格数据，分析了价格调整的频率和幅度，并与美国结果对比，揭示了价格粘性的特征。
Prices of goods and services do not adjust immediately in response to changing demand and supply conditions. This paper characterizes the average frequency and size of price changes in the euro area and its member countries, investigates the determinants of the probability of price changes, and compares the evidence for the euro area with available U.S. results. The facts documented in this paper are based on evidence from individual price data recorded at the store level in all euro area countries except Ireland and Greece: that is in datasets covering Austria, Belgium, Finland, France, Germany, Italy, Luxembourg, the Netherlands, Portugal, and Spain, which together account for around 97 percent of euro area GDP. The data used are the monthly price records underlying the computation of national Consumer Price Indices and Harmonized Consumer Price Indices. These data cover a large number of products selected on the basis of extensive Household Budget Surveys.
