Theft, Gift-Giving, and Reciprocity: A South African Experiment
通过一个“拿取游戏”实验，研究南非被试如何根据潜在受害者的资源转移调整其“偷窃”金额，发现小转移减少受害者总损失，大转移则增加总损失。
This paper uses a taking game to examine how South African subjects alter the amount they choose to 'steal' in response to a resource transfer from the potential victim. Any positive resource transfer significantly reduces the amount taken. 'Small' transfers reduce a victim's total losses, including the transfer and the subsequent 'theft'. Larger transfers increase a victim's total losses. This study failed to find that differences in the frame of a transfer (i.e. gift, as a bribe, or as a payment) influenced a taker's response to the transfer.
