Successful Logrolling Requires

Successful logrolling requires:

A) no additional information about the other party than his/her interests, and assumes that simply enlarging the resources will solve the problem.
B) a fundamental reformulation of the problem such that the parties are disclosing sufficient information to discover their interests and needs and then inventing options that will satisfy both parties' needs.
C) that one party is allowed to obtain his/her objectives and he/she then "pays off" the other party for accommodating his/her interests.
D) that the parties establish more than one issue in conflict and then agree to trade off among these issues so one party achieves a highly preferred outcome on the first issue and the other person achieves a highly preferred outcome on the second issue.
