Morally Monotonic Choice in Public Good Games

Complete versions of the instructions seen by the subjects can be viewed by running the software. A central innovation in our experiment was introduction of treatments with endogenous, non-binding contractions of feasible sets.The contraction seen by a subject was dependent on their choice in a previous round and on their belief about choice by another. An implication of this feature is that the specific instruction a subject would see in parts of the experiment was dynamically updated during the experiment to reflect the subject’s own choice and stated belief in a previous round.
