Experimental Design (Public) The subjects' main task is to split a fixed amount of money between two strangers for which we exogenously vary the date of participation in the experiment and the date of payment. Precisely, each subject takes the four allocations decisions listed below. At the end of the experiment, we randomly select one of the four decisions and truly implement the allocation decided by the subject. In particular, when the allocation involves strangers who are paid and/or recruited in the future, we effectively recruit and/or pay the individuals as announced. Between subjects, we will consider at least two future dates, namely in 6 months and in 12 months. If budget allows, we may also consider a 18-months horizon. We list below the allocation decisions for a 6-months time horizon, as an example. Subjects must decide how to split a fixed amount of money between: - An individual who participates in the experiment today and is paid today VS another individual who participates in the experiment today and is paid today. - An individual who participates in the experiment today and is paid today VS another individual who participates in the experiment today and will be paid in 6 months. - An individual who participates in the experiment today and is paid today VS another individual who will participate in the experiment in 6 months and will be paid in 6 months. - An individual who participates in the experiment today and will be paid in 6 months VS another individual who will participate in the experiment in 6 months and will be paid in 6 months. The first allocation decision listed above always comes first. Next, we randomize the order of the three following allocation decisions. As in Enke et al (2022), these decisions are all taken with a slider that subjects can move from the individual on the right of the screen to the individual on the left of the screen. Whether a given individual appears on the right or on the left is also randomized.

Additional remark (October 2025): We will also consider treatments in which all dates - payment and participation - are in the future.
