Riron to Hoho / Sociological Theory and Methods
本稿は，一方的最後通牒ゲームを同じ二人の被験者間で繰り返し行う条件と，毎回異なる相手と繰り返し行う条件を比較することで，提案者が金銭を分配するときにnon-monetary punishmentに対する互恵性が存在するかどうかを検討した．実験の結果，一つ目の条件では応答者が提案を承諾すると拒否した場合よりも提案者は次のラウンドで高い分配額を提案するが，二つ目の条件ではそうならないことがわかった．この結果は，金銭を分配する人々の行動がnon-monetary punishmentに影響を受け，さらに互恵的に振る舞うことを示唆している． Comparing the results obtained in an experiment on the fixed matching impunity game with multiple rounds and those obtained in an experiment on the random matching impunity game with multiple rounds, we examine whether reciprocity under the condition of non-monetary punishment exists when proposers distribute money. The experimental results indicate that, in the fixed matching treatment, proposer participants offered more money to receiver participants when the receiver participants had accepted the offer in the last round than when the last offer was rejected, but in the random matching treatment, proposer participants did not. This result suggests that proposers can be affected by non-monetary punishment and act on a reciprocal basis.
