Gray major diagonal). Israeli senders show no increased expectations for receivers
Fourth, we tested the impact of cultural Ticular collective behavior for the first time. We show that when similarity involving nations depending on the Euclidean distance around the Hofstede cultural dimensions. Israeli senders show no increased expectations for receivers from Israel but give considerably more than they count on to get. Persons from India anticipate to get far more from their ingroup and don't favor their own group on best of that. Germans even count on to obtain rather little in the ingroup but transfer far more than they anticipate to obtain. All round, the detailed analyses show that ingroup favoritism varies quantitatively too as qualitatively between nations. There is certainly no added effect of spatial distance involving sender and receiver nations on net-transfer. As a third element, we tested for effects of inequality aversion because of variations within the degree of wealth according to GDP per capita (corrected for purchasing energy) (www.imf.org/external/ pubs/ft/weo/2014/01/weodata/download.aspx) for the sender minus that for the receiver. In doing so, we locate a wealth distinction effect on net-transfer. In line with all the inequality-aversion argument introduced above, persons give much more than they anticipate to acquire to persons from poorer nations but anticipate much less cooperation from these persons. Fourth, we tested the impact of cultural similarity amongst nations based on the Euclidean distance around the Hofstede cultural dimensions. Contrary to the assumption that 02699931.2015.1049516 social preferences might be positively shaped by cultural similarity, we find that the tendency of people to provide additional than they expect overall decreases with cultural similarity. Detailed analyses on the Hofstede dimensions (which includes all other predictors from Table 2) reveal that net-transfers increase with similarity concerning masculinity but lower with cultural similarity regarding power distance and uncertainty avoidance. Finally, we analyzed data from our postexperimental questionnaire, in which participants rated the other nations on cooperation-related and nonrelated attributes regarding their effects on transfers and expectations. We thereby obtain that perceived wealth is usually a predictor for expectations, b = 1.64, t(1,024) = two.96, P = 0.003 and net-transfers, b = -2.06, t(1,024) = -5.22, P dar.12324 two), and net-transfers (model three) by the sender's and receiver's nation of origin also as all two-way interactions, that are reported in SI Appendix, Table S3.
