Both preference
John
and
Mary
are so defined that (
{
John

Mary
},
Yung Kee
) is more preferred to any other coalitional acts.

Both private beliefs
bel
John
and
bel
Mary
in
B
are defined as follows.
If
α
1
John
α
2
,then
bel
Mary
(
α

John
α
2
), except that we replace
all occurrences of
bel
Mary
((

, Yung Kee
)
John
α
)
by
bel
Mary
((
{
John

, Bonheur Restaurant
)
John

)
for any
α
. Similarly, if
α
1
Mary

,then
bel
John
(
α

),
except that we replace all occurrences of
bel

1 Arguably we should also replace all occurrences of
bel
Mary
((
{
John

,
Yung Kee
)
John
α
)by
bel
Mary
((
{
John
}, Bonheur Restaurant
)
John
α
) for any
α
(and simi-
larly for
bel
John
), but this does not affect the results of analysis.
