Definition 2 (SPi) Social proximity is a measure of the distance be-
tween
i (dictator) and j (recipient). In our context social proximity
may take on values in the interval [0, 1]: 0 (if
j Si); 1 (if j Fi and
the identity of the recipient is known for sure); 1/
fi (if j Fi and the
identity of the recipient is unknown).

Definition 3 (SIi) Social integration of player i is a measure of his/her
outstanding cooperation links.

Players with high levels of social integration are involved in long-run
relationships where cooperation is sustainable. This is highly corre-
lated with the number of friends, or degree-out, |
Fi|, and individual
centrality measures. The initial paper in this literature is undoubtedly
that of
Mobius, Rosenblat and Quoc-Anh (2005) (hereafter MRQ). To
elicit the social network at Harvard dorms MRQ use a coordination
device (with monetary incentives) that lets subjects choose friends
from a list and offers a prize (with some probability) when subjects
coordinate naming each other (see Table 1)8
.

8 A recent paper by Haan, Koreman and Riemersma (2006) uses “inside” information from
teachers to elicit the social network in a group of children.
