Interim agreements:
Zeno, Parkinson, and Nash

Zeno's paradoxes of motion, which claim that moving from one point to
another cannot be accomplished in finite time, seem to be of serious
concern when moving towards an agreement is concerned. Parkinson's Law
of Triviality implies that such an agreement cannot be reached in
finite time. By explicitly modeling dynamic processes of reaching
interim agreements and using arguments similar to Zeno's, we show that
if utilities are von Neumann-Morgenstern, then no such process can
bring about an agreement in finite time in linear bargaining
problems. To extend this result for all bargaining problems, we
characterize a particular path illustrated by Raiffa, and show that no
agreement is reached along this path in finite time.
