To understand this part, read first the Experimental Design.
The main intervention is in the second stage of the experiment. Here, I exogenously manipulate the composition of the subjects' pool. Some subjects therefore end up in a pool in which most AP chose to Pay in Decision 1, and some subjects end up in a pool in which most AP chose to Not Pay in Decision 1 (this, of course, depends on how many subjects chose to Pay in Decision 1; if for example all of them chose to Pay, then the two pools will consist only of AP who chose to Pay in Decision 1). The PP, who only make hypothetical decisions (and are told so), are always placed in a pool in which most AP chose to Not Pay in Decision 1.
Main hypothesis: Subjects in groups of multiple AP are more likely to choose to Pay when they are in a group in which most people chose to Not Pay in Decision 1 than when they are in a group in which most people chose to Pay in Decision 1. This hypothesis is tested between-subject (second stage) and within-subject (third stage).
Second hypothesis: If most people in a group chose to Pay in Decision 1, then the PP is better off in a group of one than in a group of multiple AP. If most people in a group chose to Not Pay in Decision 1, then the PP is better off in a group of multiple than in a group of one AP. This hypothesis is tested within-subject (third stage).
