Session-effects in the laboratory
澄清实验经济学中不同场次间被试观测值可能存在的相关性，分析场次效应的成因、形式及潜在问题，并指出标准解决方案的不足。
Abstract In experimental economics, where subjects participate in different sessions, observations across subjects of a given session might exhibit more correlation than observations across subjects in different sessions. The main goal of this paper is to clarify what are session-effects: what can cause them, what forms they can take, and what are the potential problems. It will be shown that standard solutions are at times inadequate, and that their properties are sometimes misunderstood.
