In this article, we investigate the relative weights of fairness and strategic con- siderations of proposers in the ultimatum game. For that purpose, we perform a total of 3 separate meta-analyses involving 97 observations of simple ultimatum games in 42 articles published between 1983 and 2012 on the one hand and 150 ob- servations of simple dictator games in 70 articles published between 1986 and 2014. Among the included explanatory variables, the country where the experience is run and being a student in economics have a significant impact on the offered amount in the ultimatum game. In the dictator game, the country where the experiment is run and the double-blind protocol significantly impact the amount given by the dictator. Our comparative pooled meta-analysis also reveals that players from less industrialized countries tend to have a greater proportion of fairness considerations.
