We are conducting a meta-analysis assessing how people form coalitions in a simple weighted majority game (Komorita, 1984).

Coalition formation is defined as ‘the joint use of resources to determine the outcome of a decision in a mixed-motive situation involving more than two units’ (Gamson, 1964, p.85).
If you have a study (published or unpublished) that fulfils the inclusion criteria below, please inform us via an email to:

h.rabinovitch@uva.nl

We are interested in any study or dataset with experimental data that studies coalition formation. If you have any questions/doubts, please don’t hesitate to write to us.
Looking forward to reading your work!

Inclusion criteria:
1. Participants are assigned to groups of 3 or more;

2. Each participant in a group is endowed with some resources (hypothetical or converted to real payoff);

3. For a coalition to be formed, the coalition must possess a certain amount of resources (or votes), which cannot be achieved by a single player;

4. The formed coalition specifies how the gained resources would be distributed between the coalition members;

5. The coalition members and/or distribution of payoffs can be suggested by the players or by an exogenous agent;

6. The task can be either non-contextualized or contextualized (e.g., power struggle: Cole et al., 1995; landowners: van Beest et al., 2003;

7. Collations can be agreed upon via various protocols (e.g., one step protocol, Komotita & Meek, 1978; tentative coalition protocol, van Beest et al., 2008);

If your study fits with our criteria, please send us your paper/data so that we can include it.
