Can't Touch This! Similarity And The Willingness to Keep "Dirty Money"

Traditionally, allocations by dictators in Dictator Games (gifts) have been explained by aspects of altruism, reciprocity, and fairness. However, this assumes the gift to be desirable to the dictators and responder. Giving may also be driven by the source of the endowment. We examine this by using three sources to generate the endowment in a Dictator Game:(1) undergraduate students, (2) Amazon Mechanical Turk workers, and (3) users of a racially/ethnically charged web forum. This endowment is provided to subjects in a traditional laboratory experiment. We find dictator similarity with the source of the endowment influences their allocation decision; the more similar subjects feel to the source the more of the endowment they keep. Our results suggest that decisions can be strongly influenced by the provider of income shocks.
