在本文中，我们提出的证据，自我形象的关注，在慈善捐赠使用实验室实验。受试者做出一系列的三个决定，在他们自己和一个被动的接受者（慈善机构或实验者）之间分配10英镑的捐赠。在做这些决定时，受试者被告知，他们中的一个将在最后被随机选择，以确定收益。在所有的决定都已经做出并且已经揭示了哪个决定将决定收益之后，我们为受试者提供了一个机会，让他们选择退出最初的决定，并获得10英镑。我们发现，近四分之一的受试者选择退出，而大约三分之一的受试者选择退出积极捐赠。当一个被试决定改变给予的决定，并选择保留全部金额时--这是她做出第一个决定时可以选择的，但没有行使--这一事实表明，最初的给予并不仅仅是出于对接受者的利他主义。我们认为，选择退出可以解释通过一个组合的自我信号由于饱食的好处减少，并在选择退出阶段给予的成本增加，因为它们是实现的确定性。
In this paper we present evidence of self-image concerns in charitable giving using a laboratory experiment. Subjects make a series of three decisions of allocating an endowment of £10 between themselves and a passive recipient that is either a charity or the experimenters. When making these decision subjects are informed that one of them will be chosen randomly at the end to determine payoffs. After all decisions have been made and it has been revealed which decision will determine payoffs we offer subjects an opportunity to opt out from their initial decision and receive £10 instead. We find that almost a quarter of subjects choose to opt out, while around one third opt out from a positive donation. The fact that a subject decides to revise a decision to give and chooses instead to keep the whole amount – an option that was available when she made the first decision and was not exercised – indicates that giving in the first instance was not motivated solely by altruism toward the recipient. We argue that opting out can be explained through a combination of a reduced benefit of self-signaling due to satiation, and an increase in the costs of giving at the opt out stage, as they are realized with certainty.
