Abstract

This paper explores excuse-driven behavior in giving. In our powered laboratory experiment, participants play Dictator Games sharing 5e or 1,000e under certainty or ambiguity with a charity. In contrast to previous papers using MPLs {that necessarily introduce additional layers of uncertainty{our subjects participate in two DGs. We �nd no evidence that people use moral wiggles to hide their sel�shness. They share equally out of 5e under certainty and ambiguity and as much out of 1,000e under ambiguity as they do under certainty in the previous literature. These �findings raise the question whether previous results might be an artifact.
