Pendulum Arbitration

An approach to arbitration where the arbitrator selects either one of the proposals without modification, designed to discourage unreasonable demands from both parties.

Pendulum arbitration (often called final-offer arbitration) is a dispute-resolution method where each side submits a final proposal and the arbitrator must pick one offer in full rather than “splitting the difference.” The point is to create incentives for both sides to make more reasonable final offers.

Why It Changes Bargaining Behavior

In conventional arbitration, parties may have an incentive to ask for extreme outcomes if they expect the arbitrator to compromise. Pendulum arbitration changes that calculus:

  • If you submit an extreme offer, you raise the probability the arbitrator chooses the other side.
  • If you submit a moderate offer, you may sacrifice some payoff but increase the probability of winning.

This can move final offers closer to what each side believes the arbitrator views as “reasonable,” reducing strategic posturing and sometimes speeding settlement.

Where It Is Used

Pendulum arbitration shows up most often in settings like:

  • public-sector wage disputes where strikes are constrained,
  • sports salary arbitration,
  • labor negotiations where parties want a binding backstop without encouraging extreme demands.

Trade-offs And Practical Limits

Pendulum arbitration is not a magic fix:

  • Outcomes can still be noisy if arbitrator preferences and criteria are unclear.
  • Parties may try to influence perceptions about what is “reasonable” (information and framing battles).
  • If the stakes are very high, risk-averse parties may settle early, but risk-seeking parties may still gamble.

From an economic design perspective, it is a tool for shifting bargaining incentives, not eliminating underlying distributional conflict.
