Although the overall level of probabilities is an artifact of the preference set chosen, some additional evidence of variation as issues are added is given in figure B.3, which uses the rotation set. It should be noted that, no matter what preference set is chosen, the probability of trading can only approach unity. There is always one non-trading vector set--when all preference orderings are identical.
In "real" situations, each legislator will have, of course, only one preference vector instead of several, and the probability of trading in any legislature, commission, or committee will be a function of that one vector set. It may be worthwhile, however, when devising new commissions, special districts, or other decision structures, to take some note of the number of independent issues likely to come before such bodies and to examine the
