1. if both are from your own group,2. if both are from the other group, or3. if one is from your group, <strong>and</strong> one is from the other group.For each scenario, you must allocate all tokens between the two participants. Allocations haveto be integers. Do not allocate any tokens to yourself. Your answers will be used to determineother participants’ payoffs. Similarly, your payoff will be determined by others’ allocations.After everyone finishes recording their decisions, the computer will r<strong>and</strong>omly select a roundamong the five rounds that is used to calculate the payoffs. Each round of decisions will have anequal chance of being chosen.Next, the computer will generate a r<strong>and</strong>om sequence of the ID numbers. The first number inthe sequence will be the ID number of the person who allocates to the second <strong>and</strong> third IDs. Thesecond ID drawn will allocate to the third <strong>and</strong> fourth IDs, , <strong>and</strong> so on. The last ID will allocate tothe first <strong>and</strong> second IDs. Therefore, your payoff will be the sum of tokens allocated to you by thetwo participants preceding you.For example, the computer generates the following sequence of the ID numbers, 9, 4, 1, 5, 12,· · · , 2, <strong>and</strong> 3. Then subject 9 will allocate tokens to subject 4 <strong>and</strong> 1. Subject 4 will allocate tokensto subject 1 <strong>and</strong> 5, · · · , <strong>and</strong> so on. Subject 3 will allocate to subject 9 <strong>and</strong> 4. Therefore, subject 1’spayoff will be the sum of the tokens allocated to her by subject 9 <strong>and</strong> subject 4.[New Screen]Please record your decisions under the three scenarios below.Note: For each scenario, you must allocate all tokens between the two participants.
