Plott and Zeiler (2007) manage to extinguish exchange asymmetry—but as a result of failing to control for whether the items are presented sequentially or simultaneously. This study examines the effect of timing. It finds that exchange asymmetry emerges when the timing is sequential, even when we follow the Plott/Zeiler methodology, i.e., use lottery.
