A reproduction and replication of Engel’s meta-study of dictator game experiments.

In this paper, we reproduce Engel’s (2011) meta-study of dictator game experiments using his data, and then replicate it using our own data. We find that Engel’s (2011) meta-study of dictator game experiments is quite robust. We show that meta-analyses of dictator game experiments depend to an extent on the definition of independent variables and consistent coding of studies. This insight pertains in particular to the take-option, which has produced important questions (Bardsley 2008; List 2007; Guala and Mittone 2010) about the epistemological inferences one can draw from dictator game experiments.
