摘要:Prices usually adjust much faster when costs increase than when costs decrease. The mechanism driving this "rockets-and-feathers" phenomenon is not well understood, despite ample empirical evidence of its existence. We use simple experimental markets with and without consumer search and either privately or publicly observed cost shocks to study this puzzle. In contrast with the theoretical predictions, we observe price dispersion and asymmetric price adjustment in all four settings. We attribute the pricing behaviour to bounded rationality and its interaction with adaptive expectations. Neither search costs nor private information is indispensable for prices to adjust asymmetrically.演讲者简介：Dr Ke Changxia于澳大利亚阿德莱德大学获得经济学博士学位，现为德国Max Planck税法与财政研究所（慕尼黑）高级研究员。主要研究领域包括微观经济学、实验与行为经济学、产业组织理论、公共经济学等。
