Experimenters make theoretically irrelevant decisions concerning user interfaces and ordering or labeling of options. Reanalyzing dictator games, I first show that such decisions may drastically affect comparative statics and cause results to appear contradictory across experiments. This obstructs model testing, preference analyses, and policy predictions. I then propose a simple model of choice incorporating both presentation effects and stochastic errors, and test the model by reanalyzing the dictator game experiments. Controlling for presentation effects, preference estimates become consistent across experiments and predictive out‐of‐sample. This highlights both the necessity and the possibility to control for presentation in economic experiments.

控制演示效果

实验者在理论上与用户界面,选项的顺序或标签无关的决定。重新分析独裁者博弈,我首先证明了这样的决定可能会极大地影响比较静力学,并导致结果在整个实验中显得矛盾。这阻碍了模型测试,偏好分析和策略预测。然后,我提出了一个简单的选择模型,该模型同时考虑了表现效果和随机误差,并通过重新分析独裁者博弈实验来测试该模型。通过控制表现效果,偏好估计在整个实验和预测性样本外变得一致。这突出了控制经济实验中呈现的必要性和可能性。
