With strategic substitutes, commitment power tends to decrease in efficiency whereas the opposite

“Social Distance, Moral Property Right and Value of Gratitude in Dictator Game”
Gratitude is perceived as an intangible property right with value. Would the degree of association
and familiarity affect the valuation? Will a person’s background shape the valuation? Will the
setting influence the valuation? The research designed a dictator game and distributed the survey to
students from various nationalities across universities in Netherlands to answer those questions. The
result from 161 respondents showed the answer is yes, yes and yes. Closer social relation correlated
with higher valuation for gratitude while nationality, field of study and political orientation are good
predictors for a person’s valuation relative to sample average. The setting where a respondent is an
impartial arbitrage generates higher valuation than that where respondents take financial loss for the
valuation.
