“…Researchers have shown, for example, that women send more money to their interaction partner only when risk is not involved (i.e., in the role of a trustee versus that of trustor in a trust game; Buchan, Croson, & Solnick, 2008;Croson & Buchan, 1999) and that the expected return partially mediates the influence of sex on the amount sent (Buchan et al, 2008). Furthermore, studying behaviour in a one-shot public goods game, women contributed significantly less than men and this difference is substantially driven by their lower expectations (Greig & Bohnet, 2009). Finally, considerable sex differences concerning trust could be observed in a recent cross-cultural study including participants from 17 nations (Romano, Balliet, Yamagishi, & Liu, 2017).…”
