Why Are Prices Sticky? Preliminary Results from an Interview Study
通过访谈实际定价者，检验了十几种价格粘性理论的有效性。基于前72次访谈的初步结果显示，典型企业每年调价一次，价格调整通常滞后于需求或成本冲击3-4个月。
This paper reports preliminary results from a large research project on business pricing which is currently underway. The idea is to use interviews with actual price setters to assess the validity of a dozen theories of price stickiness. The rather unorthodox (for economists) methodology is defended; the research design is described briefly; and a few results based on the first 72 interviews (out of a projected 200) are presented. This sample suggests that the median firm changes its price annually and that price adjustments typically lag 3-4 months behind shocks to demand or cost.
