Behavioral games
Run a Dictator Game
Study unilateral allocation choices between human or model players with explicit endowments and recipients.
The basic idea
In the Dictator Game, one allocator chooses how much of an endowment to transfer to another player, who has no veto. It is commonly used to study allocation behavior, but a transfer alone does not identify a single motive such as altruism or fairness.
Give Player 1 an endowment of 100 tokens and record how much they send to Player 2 across model–model, human–model, and human–human sessions.
How to do it
- 1
Assign the allocator to the first seat and the recipient to the second.
- 2
Set the endowment, payoff label, repetitions, actor types, and feedback policy.
- 3
Keep instructions equivalent across actor-composition conditions unless wording is an experimental factor.
- 4
Analyze transfers with the session configuration, round number, actor type, and repeated-measures structure.
What to watch for
- Order and labels can cue generosity.
- One-shot and repeated games answer different questions.
- A model's token transfer is simulated behavior, not evidence of stable human-like preference.
What a useful result looks like
Each round records the allocation and resulting payoffs for both seats, supporting direct comparisons across prespecified actor compositions.
